General
1. Q. In the Rate Category & Load data file on the RFP Web site, does the data for Rate Schedule GS-3 in the SCI and SCI 2008+ tabs comprise data for the entire rate class or only those customers with less than 500 kW peak demand? Will data for Rate Schedule LP-4 customers with less than 500 kW peak demand be provided?
  A.

Thank you for bringing this to PPL Electric's attention. Updated data have been posted to the RFP Web site, and an announcement was sent to all Web site registrants on July 15, 2009 regarding this posting.

Under PPL Electric's Default Service Procurement Plan ("DSPP"), Rate Schedule LP-4 customers with less than 500 kW peak demand will be included in the Small Commercial and Industrial ("Small C&I") Customer Group and Rate Schedule GS-3 customers with 500 kW or greater peak demand will be included in the Large Commercial and Industrial ("Large C&I") Customer Group. The determination of peak demand will be based on the customer's peak load contribution to PJM peak load in the PJM 2008-2009 Planning Year. This initial determination of peak demand and classification of customers will remain effective for the entire term of PPL Electric's DSPP.

Historical hourly load data provided for Rate Schedule GS-3 customers and Rate Schedule LP-4 customers do not include the breakdowns based on the initial determination of peak demand. However, customer counts and load percentages based on the initial determination of peak demand and classification of customers are provided in the "main" tab of the updated load data spreadsheet. Monthly sales and customer count information have been updated to provide additional data for Rate Schedule GS-3 and LP-4 customers between the Small C&I Group and the Large C&I Group based on the initial determination of peak demand and classification of customers.

2. Q. Why are there gaps of data missing in the Residential and SC&I historical hourly data files? 
A. Historical load data is not available the period 12/23/2007-1/02/2008 and 2/21/2008. PPL Electric has been deploying an Advanced Metering Infrastructure (AMI) over the past few years, which has resulted in the replacement of all 1.4 million meters. As with any new system, there have been some problems during the transition, which have resulted in the loss of hourly load data. PPL Electric has been working with their vendors in an effort to eliminate issues such as this. PPL electric is also installing a Meter Data Management System, which will be functional later in 2009, that will ensure that hourly data are available for all hours. 
3. Q. Please provide historical hourly data broken out by all eligible customers, default service customers, and shopping customers. 
A. As stated on the tab of the data spreadsheet labeled "Main," all load values are total retail (including shopping). PPL Electric only has aggregate load data for shopping customers. Currently, most of the shopping customers are in the Large Commercial and Industrial ("C&I") Group and supply for the Large C&I customers is not part of the August 2009 solicitation. PPL Electric does not have historical hourly load data for shopping customers broken out for the rate schedules in the Residential Group or the Small C&I Group. 
4. Q. How are the PLCs provided in the RFP Rules calculated, and what is the underlying reason for the jump in the Residential PLC and Small C&I PLC values compared to the March 2009 solicitation under PPL Electric's Competitive Bridge Plan? 
A.

PJM Forecasted PLCs are referenced in DSPP RFP Documents and are used to delineate the number of tranches and tranche size (MW) which are then used in the RFP auction.  They represent expected PLC based upon the PPL Zone according to PJM – taking into consideration a number of factors including, but not limited to customer and consumption growth, weather variations, and economic trending.

There are a number of reasons why 2010 forecast PLCs differ from 2011 & 2012 PLCs – the first of which is that the 2010 PLCs referenced in the CBP are the result of a forecast based upon 2005 peak load, whereas the 2011 and 2012 PLCs referenced in the DSPP are the result of a forecast based upon 2008 peak load.  The more recent PLCs incorporates updated assumptions not previously available in 2005 – the greatest of which are changes in weather and economic trending.

Please reference the 2009 PJM Load Forecast Report (found here) which dictates differences from the 2008 Forecast PLC and includes projected PLCs per zone.  Important take-away points from this report include a 4.2% decrease in forecast 2008 PLC to forecast 2009 PLC.  Furthermore, page 13 of the report shows two graphs (summer and winter peak demand) that include actual historic demand and forecast demand; both of which show significant changes from season to season and year to year.  Finally, the report also shows that PPL's forecast 2011 and 2012 values are nearly exactly the same as PJM forecast values.

We would like to emphasize that all of these PLCs are "forecast" values, based upon a litany of assumptions, and therefore will change to match actual peak load once supply begins.  Also available are historic PLC values found in the "Rate Category and Load Data" workbook on PPL's DSPP Site (found here), which show changes and variations in PPL Zone PLC from year to year, from 2004 to 2008.

5. Q. Please provide the PLC values from June 2009 through May 2010 for both Residential and Small C&I Customer Groups.
A. Please see the file titled "PPL-ICAP-PLCValues-072209.xls", available here
6. Q.

Please provide the hourly aggregate historical load for the adjusted GS-3 (without 500 kW and above) and adjusted LP-4 (without 500 kW and below) categories.

A.

PPL Electric is unable to provide hourly aggregate historical load due to the way PPL Electric's system gathers and breaks-down the data according to profile type. PPL Electric's load data is an aggregate load value across all rate classes – each rate class has an applicable load profile associated with it, which is then applied to the aggregate load number to break-down this number into specific rate classes. Because those customers within the rates classes GS-3 and LP-4 above and below 500 kW are imbedded in the rate profile for GS-3 and LP-4 as a whole, not based upon kW usage, they are unable to be specifically broken out. This is unlike energy usage data which is aggregated on a bottom-up approach, aggregating usage data on a meter by meter basis. For this reason, monthly break-downs of GS-3 and LP-4 customers (according to the 500 kW split) is the only data available within the "Rate Category & Load Data" spreadsheet.

7. Q. What process is PPL Electric required to follow to change the classification of customers, rate classes or strata among Customer Supply Groups? Will PPL Electric publicly file with the PUC if the Company were to propose making such a change? What notification and revised load data will PPL Electric provide to Sellers and RFP Bidders?
A.

The Customer Supply Groups are defined in the Default Service Procurement Plan reviewed and approved by the Commission. Those Customer Supply Groups are:

The Residential Customer Group, which includes rate schedules RS, RTS and RTD.

The Small Commercial Customer Group, which includes small commercial and industrial customers served under rate schedules GS-1, GH-1, GH-2, IS-1, BL, SA, SM, SHS, SE, TS, SI-1, Standby and the customers from the following rate schedules whose peak demand is less than 500 kW: GS-3, LP-4.

The Large Commercial and Industrial Customer Group includes customers on rate schedules ISP, LP-5, LP-6, LPEP, IST, ISM and the customers from the following rate schedules whose peak demand is equal to or greater than 500 kW: GS-3, LP-4.

PPL Electric does not expect to change the rate schedules that are part of each Customer Supply Group for the duration of the PUC-approved Default Service Procurement Plan, other than as required to comply with applicable regulation and/or legislation. If any change to the rate schedules that are part of each Customer Supply Group occur, notification will be issued.

The PPL Electric EGS Coordination tariff explains the process of developing the load profile for each rate class and can be found at: click here. Any changes to the EGS Coordination tariff must be submitted to the PUC for review.

8. Q. When does the reclassification of GS-3 customers with peak demand equal or greater than 500 kW and LP-4 customers with peak demand less than 500 kW take effect?
A. This reclassification of GS-3 customers with peak demand equal or greater than 500 kW and LP-4 customers with peak demand less than 500 kW takes effect on January 1, 2011. Under PPL Electric's Default Service Procurement Plan ("DSPP"), Rate Schedule LP-4 customers with less than 500 kW peak demand will be included in the Small Commercial and Industrial ("Small C&I") Customer Group and Rate Schedule GS-3 customers with 500 kW or greater peak demand will be included in the Large Commercial and Industrial ("Large C&I") Customer Group. The determination of peak demand will be based on the customer's peak load contribution to PJM peak load in the PJM 2008-2009 Planning Year. This initial determination of peak demand and classification of customers will remain effective for the entire term of PPL Electric's DSPP.
9. Q. What was the PLC and NSPL per tranche for Residential and Small Commercial & Industrial customers for the PJM planning year from June 1, 2009 through May 31, 2010?
A.

The capacity Peak Load Contribution values for the PJM planning year from June 1, 2009 through May 31, 2010 are:

Residential: 2876 MW
Small Commercial & Industrial: 1976 MW
Large Commercial & Industrial: 1885 MW

The NSPL or Network Service Peak Load value applies only to transmission costs for which PPL Electric is responsible and is not a component of the supplier's costs; therefore is not provided. As stated in section 2.3 of the Full Requirements SMA, "Buyer shall be responsible, at its sole cost and expense, for the provision of Network Integration Transmission Service for PPL Electric customers and distribution service necessary to serve the Specified Percentage."
 
Please note that data has been posted, which shows GS-3 loads relative to total SC&I loads and LP-4 loads relative to LC&I loads.  Data has also been provided, which shows the percent of GS-3 sales above 500 kW and the percent of LP-4 sales under 500 kW.  Hence using energy based ratios you can estimate PLC values.

10. Q. Please confirm that the PLC provided for the Small Commercial and Industrial Group excludes all customers in the LP-4 rate schedule. If that is so, please provide the PLCs of GS-3 customers that would be removed since their peak demand is >500 kW and the PLCs of the LP-4 customers who will be added since their peak demand is <500 kW.
A. This is correct, the PLC provided for the Small Commercial and Industrial Group excludes all customers in the LP-4 rate schedule. We are unable to provide the requested information at this time. As described in question Data/General FAQ-4, the PLCs for Residential Customers, Small C&I and Large C&I are all forecast PLCs, calculated by PPL Electric for the rate classes and their customers within those classes. The gross PLC value is based on the prior years peak, which is weather normalized, and then this value is broken down by rate class according to the rate class profile. The current profile does not include this distinction (the GS-3 and LP-4 customers > and < 500 kW) and attempting to remove specific customers from the profile could disrupt the integrity of the profile. Also, please note that these PLCs are forecasts and will change once actual supply begins.
11. Q. With reference to the information regarding GS-3 and LP-4 customer breakdowns provided on the main tab of the "Rate Category & Load Data" workbook, it appears that you used some sort of PLC data to supply estimates of the energy and customer count breakouts.  Why can't the PLCs be summed to provide PLC Data for the Small C&I customer group?
A.

The data regarding GS-3 and LP-4 customers supplied in the on the main tab of the "Rate Category & Load Data" workbook, breaking out customer counts and estimated kWh usage was derived looking at actual historical usage data by customer (as provided in the Rate Category & Load Data workbook on the DSPP Web site), not vetting out these numbers based upon capacity values.  As described in Data/General FAQ-10, rate class profiles do not currently exists for 2011 and beyond, therefore PLCs for GS-3 and LP-4 cannot be individually tabulated.  For this reason, PLCs cannot be summed, as you have requested.

Please see also Data/General FAQ-12 for more information.

12. Q. With reference to Data/General FAQ-10 and Data/General FAQ-11, please provide a breakout of the 2009-10 PLCs, which are in existence today, for Small C&I (with GS-3 and LP-4 Customers below 500 kW) and Large C&I customers (with GS-3 and LP-4 Customers at or above 500 kW).
A.

The data system is not currently set up to retrieve and delineate the requested capacity data according to the 500 kW break-out for GS-3 and LP-4 customers.  While the raw information exists, the classes are currently delineated according to a predescribed profile, not aggregated as usage data is from individual customer meters. The historical capacity PLC data posted on the RFP Web site was not developed by summing individual customer PLCs, but by using profiles.  Hence, it is not an easy exercise to change customer group definition.  PPL Electric is attempting to pull the requested data, but will not be able to provide this information before the Bid Proposal Due Date of August 11, 2009, for this first solicitation. This information will be posted to the RFP Web site when it becomes available and an announcement will be sent to all Web site registrants. PPL Electric expects to have this information available in time for the second solicitation Bid Proposal Due Date of October 20, 2009. 

Please note that data has been posted, which shows GS-3 loads relative to total SC&I loads and LP-4 loads relative to LC&I loads.  Data has also been provided, which shows the percent of GS-3 sales above 500 kW and the percent of LP-4 sales under 500 kW.  Hence using energy based ratios you can estimate PLC values.

Please also see Data/General FAQ-5 for the file titled "PPL_ICAP_PLC_Values_072209.xls" regarding the latest PLC values for all Customer Groups.

13. Q. Please provide PLCs by rate class for all eligible customers, default service customers, and shopping customers.
A. Please refer to the Rate Category and Load Data found (here) for PLC data broken out by month and for all customer classes.  We are unable to provide any greater granularity on this data at this time.  Please refer to Data/General FAQ-4 for more information.
14. Q. The highest historical PLC for the Residential Group in the last three years has been 2,975, however, forecast PLCs are in the 3,500 to 3,700 range.  Please explain the over 20% growth expected in this class by 2011.
A.

There are a number of reasons why 2010 forecast PLCs differ from 2011 & 2012 PLCs, and concurrently, why they do not seemingly match provided historical values.  Historical values are actuals, whereas forecast values are based on a number of assumptions and trending, derived through PJM modeling assumptions.  Please reference question 4 above which describes how forecast PLCs are derived by PJM.  Also, please take into consideration that the forecast values are just that, forecasts, and therefore will change when actual peak load contributions become available once supply starts.

15. Q. How is the tranche size calculated?
A. The tranche size is calculated by dividing 100% by the total number of tranches for a Customer Group.  The total number of tranches for a Customer Group is determined on the basis of the Peak Load Contribution (not on the basis of historical hourly load data) determined so that each tranche is approximately 50 MW of PLC for that Customer Group.  Please note that the PLC for a Customer Group includes customers on Default Service as well as customers that take service from an EGS.  Please see Data/General FAQ-4 for information about how the PLCs provided in the RFP Rules are calculated. As stated in section 1.1.16 of the RFP Rules, "…A Default Service Supplier serving one tranche in a particular product for a Customer Group is responsible for serving a fixed percentage of that Customer Group's Default Service Load represented by one tranche…"
16. Q. The sum of the 2008 MWh for the GL rate class in the "Rate Categories and Load Data" file equals 2,185,799 MWh.  The sum of the 2008 MWh for the GL rate class in the "Size Distributions" file equals 1,982,234 MWh.  Which one of these data sets is correct?
  A. First, there is no GL rate class – there is a BL rate class and a series of GS rate classes.  We believe the 2,185,799 MWh value you supplied comes from adding the 2008 Small C&I data for GS-1 and BL (under Rate Category & Load Data); we also believe the 1,982,234 MWh value is derived by adding the GS-1 data for 2008 (under Size Distributions).  Based upon this assumption, the reason there is a difference between these values is that the MWh value in the Rate Category & Load Data includes BL, or Borderline, customers which is an estimate value – BL is not included as a component of the GS-1 MWh within the Size Distribution file.  Both are correct values and can be used, but simply contain different classes as defined in the heading.
17. Q. In the main tab of the rate categories and load data file, customer counts are provided for the GS3 (20,642) and LP4 (1,016) rate classes. What date are these customer counts as of? Why don't these customer counts correspond to the counts in the MonthlyBillCounts tab of the same spreadsheet for either class?
A. The customer count break-outs for GS-3 and LP-4 customers on the "Main" tab of the Rate Category and Load Data workbook were tabulated as of June 10, 2009.  The summed values you've provided in your question differ from the Monthly Billed Counts because many small and large commercial and industrial customers receive multiple bills, but are listed as a single customer.  Thus, there will be a difference between the customer count numbers and monthly billed counts.
18. Q. What was the PLC on 5/31/09, 6/1/09 and 9/30/09 for all three customer classes?
A. PPL Electric does not currently have this information readily available.
19. Q. What was the NSPL on 12/31/07, 1/1/08, 12/31/08, 1/1/09, 9/30/09?
A. PPL Electric does not currently have this information readily available.
21. Q. Can you provide the daily zonal scaling factors for PPL zone from June 2007 through January 2010?
A. Zonal Scaling Factors for the 2009/2010 delivery year is available on the PJM Web site, here.  Additional scaling factors are not readily available and will not be able to be provided at this time.
22. Q. There has been an extreme amount of press related to Residential shopping statistics within the PPL service territory. It seems that there should be available Residential customer counts / percentages of customers that have signed up or are currently being served by EGS suppliers. Can you please provide a migration report or the current PLC for each tranche adjusted for migration?
A.

As of the week of January 11th, 2010, approximately 225,000 customers (across all classes) have switched energy suppliers. Of the approximately 225,000 customers that have switched, approximately 190,000 are Residential customers.  Depending on when each customer's meter read date is, they may have already begun receiving supply from their new supplier or will in the coming weeks. 

For additional information on PLC's per customer class, please refer to the Aggregate PLC Summary Data file for additional information that PPL Electric is providing to all bidders at this time. 

23. Q. The data file updated on January 12, 2010 includes hourly data through December 31, 2009. What period of data includes the 60-day adjustment? Please confirm that PPL has used profiles to estimate the data for the period that does not include the 60-day adjustment.
A. The data through October 31, 2009 includes the 60-day adjustments, and the data posted for November 1, 2009  through December 31, 2009 use profiles to estimate that data.
24. Q. With the rate caps having rolled off in PPL and customers starting to switch to retail competition, can you provide bidders with a 7-day forecast of PLCs by customer type for both shopping and non-shopping customers?
A.

For current energy suppliers under the Competitive Bridge Plan, in accordance with the CBP SMA, 7-day forecast data is available through PJM's eRPM Web site.  Both historical and forecast data is available according to each supplier's short name.  Additional break-outs are not available through PJM's eSuite System.

PPL Electric has also recently released some Aggregate PLC Summary Data information per class available on the PPL POLR Web site.

25. Q. There are significant differences between your monthly billed sales data and the historical hourly load values for any given month. I have seen CBP-DATA/FAQ-11, which explains the differences due to "billing timing." Can you confirm that the correct data to use for historical energy use is the hourly energy (as opposed to the billed sales energy)?
A. For actual usage during a given month, please use the hourly load data provided in the Rate Category and Load Data file. Please note that for the historical load data, all load values are for total retail customers (including shopping) at the generation level and include all losses.
26. Q. Can you provide the annual historical PLCs for the Large C&I customer group in addition to what is provided for the Residential and Small C&I customer groups. I understand that the PLCs provided for the Small C&I and Large C&I will be based on existing rate schedules used under PPL Electric's competitive bridge plan. Providing the PLCs for the Large C&I customer group will enable a recalculation of the Small C&I class history associated with the GS-3 and LP-4 class shifts?
A. As requested, historical annual PLC data for the Large C&I customer group have been provided in the capacity tab of the Rate Categories and Load Data file. Information provided for the Small C&I and Large C&I customer groups are based on existing rate schedules used under PPL Electric's competitive bridge plan. Please refer to DSPP Data/General FAQ-1 as well as the "Main" tab of the Rate Categories and Load Data file for additional monthly sales and customer count information related to the GS-3 and LP-4 rate classes.
27. Q. Please also provide NSPL values for 2010 as well as PLC values for planning year 10/11 with a breakdown between shopping and non-shopping customers.
A.

Updated annual PLC and NSPL data by Customer Group have been provided in the "Capacity" tab and "NSPL-NITS" tab, respectively, of the Rate Categories and Load Data file. The annual PLC data is only for eligible load. In addition, PPL Electric has provided, in the Aggregate PLC Summary Data file, aggregate PLC values per customer group for POLR customers to help facilitate analysis of migration levels. This data is an estimate of PLC by customer group and is only a snapshot in time.

28. Q. Please provide an updated data file which contains hourly data by rate class for both shopping and non-shopping customers.
A. Updated historical hourly load data for eligible load through February 2010, and monthly billed sales and counts for eligible and shopping customers through April 2010 are also provided in the Rate Categories and Load Data file.  For additional information regarding the hourly load data and monthly billed sales data, please also refer to DSPP Data/General FAQ-25.

PPL Electric does not expect to post additional data prior to the Bid Proposal Due Date of April 20, 2010 for this solicitation.
29. Q. Please provide PLC values for Residential load and Small Commercial & Industrial load for 12/1/2009.
A. PPL Electric does not currently have this information readily available.
30. Q. Please provide PLC data for 1/1/2010 - 1/6/2010 in the Aggregate PLC Summary Data file.
A. PPL Electric does not currently have this information readily available.
31. Q. With reference to the historical load data posted on April 8, 2010, the hourly load data for November and December 2009 appears to be identical to the data posted in January 2010 and does not appear to be updated to include the 60-day adjustment. Can you confirm this fact?
A.

PPL Electric uses the 60-day adjustment primarily to shift load from one supplier to another.  As in the historical load data provided is on an aggregate basis by rate class, and there was primarily only one supplier, PPL Electric did not perform a 60-day reconciliation.  The rate class load data on the RFP Web site is the only rate class load data that is available.  Also, please note that PPL Electric transitioned to a new Meter Data Management System (MDMS) in 2009, which became fully functional in January 2010. The MDMS provides PPL Electric with hourly data available for all hours, and will use profiles only when the hourly metered data are unavailable.

The data provided for November and December 2009 are provided using the MDMS. Suppliers are to note that this is a change in the methodology of gathering the historical load data. On a go-forward basis, PPL Electric will be relying on the new MDMS system to generate historical load data.

32. Q. With reference to the Rate Category and Load Data file that was updated on April 16, 2010, please explain what was updated.
A. The Rate Category and Load Data file that was updated on April 16, 2010, corrected for four (4) numbers; namely, the February and March 2010 data reported in the tab "ShoppingBilledSales" for the rate classes "LP4 < 500 kW" and "LP4 >= 500 kW". These four data points were previously reported in error.

PPL Electric has since provided updated historical hourly load data for eligible load through February 2010, and monthly billed sales and counts for eligible and shopping customers through April 2010 in the file dated May 21, 2010.
33. Q. Do the Monthly Bill Counts and the Monthly Billed Sales reflect only customers on default service or customers that are shopping as well as taking default service?
A.

With reference to the Rate Category and Load Data, the Monthly Billed Counts and Monthly Billed Sales data includes all customers (shopping and default service customers).

Please note that the Rate Category and Load Data file was updated on April 16, 2010. The updated file dated April 16, 2010, corrected for four (4) numbers; namely, the February and March 2010 data reported in the tab "ShoppingBilledSales" for the rate classes "LP4 < 500 kW" and "LP4 >= 500 kW", which were previously reported in error. 

PPL Electric has since provided updated historical hourly load data for eligible load through February 2010, and monthly billed sales and counts for eligible and shopping customers through April 2010 in the file dated May 21, 2010.

34. Q. Can you provide Monthly Sales without adjustments from prior months in Rate Categories Load Data file?
A. PPL Electric does not have this information readily available.
35. Q. Please provide RPM historical daily zonal scaling factors as this data is not available on the PJM RPM Web site. If available, please also provide projected PY 10/11 daily scaling factors.
A. This information is available in eRPM through eSuites from PJM.
36. Q. Do the PLC numbers on slide 21 of the bidder information webcast presentation and section 1.1.16 the Full Requirements RFP Rules reflect migration levels?
A. No, the PLC numbers provided on slide 21 of the bidder information webcast presentation and in section 1.1.16 of the Full Requirements RFP Rules are forecast values of total zonal load and are used for the purpose of determining the number of tranches needed for the RFP. Please refer to Data/General FAQ-4 for more information regarding the forecast values.

For historical PLC values, please refer to the "Rate Category and Load Data" as well as the "Aggregate PLC Summary Data" on PPL Electric's RFP Web site.
37. Q. Can you please explain the sharp drop in default service PLCs for all customer types? This drop should not be due to a change in PLC planning periods between May 31 and June 1 given the fact that the dataset only uses planning period 2010/2011 PLCs.
A. The decline in PLCs for default service customers (Aggregate PLC Summary Data) is due to migration as well as to an update by the Company to the PLCs for the 2010/2011 planning period. Please note that the update in the PLCs is only applicable starting June 1, 2010 as the 2010/2011 planning period starts on June 1, 2010.
38. Q. Has the 300 MW block energy and the 50 MW unit entitlement supply been removed from the Hourly Residential Load Values as posted on your Web site?
A. The hourly load data provided in the "Rate Category and Load Data" file reflect total zonal load of all retail customers (including shopping) on a historical basis. As such, the 300 MW block energy and the 50 MW unit entitlement supply have not been removed from this data series.
39. Q. Does the PLC value need to be grossed up to include losses or are losses already included in this value?
A. The PLC values include all losses, and do not need to be grossed up for losses.  To convert to capacity obligation they need only be adjusted by the appropriate scaling factors as described in Data/General FAQ-21 and Data/General FAQ-35.
40. Q. Can you please provide the daily Res NSPLs since the beginning of 2010 and the Res NSPL on 12/31/07, 12/31/08 and 12/31/09? Please also provide aggregate PLC and NSPL data for Residential customers as at July 3, 2010.
A. The NSPL values are available in the Rate Category and Load data file located here.  The NSPL is calculated as an annual value associated with the PPL Zone and is scaled up or down based on customer changes to match the target NSPL value calculated on an annual basis.  Additional data are not readily available and will not be provided at this time.
41. Q. Would you please post the most recent 60 day reconciled hourly load data? The reconciled load for more recent months should be available.
  A. Updated load data are now available and posted to the RFP Web site: click here. Please also consult Data/General FAQ-31 for information about the data that is provided.
42. Q. On the PA OCA Web site, the Electric Shopping Statistics document indicates the residential migration by customer load as of July 3, 2010 is 35.9%. However, when I divide the Residential POLR PLC in the Aggregate PLC Summary Data as of July 3 (1902 MW) by the total residential eligible PLC in the Rate Categories and Load Data "Capacity" tab (2809.62 MW), I get 67.7% of customers served or 32.3% migration. Which data is a better reflection of migration?
  A. PPL Electric has provided aggregate PLC values per Customer Group for default service customers in order to facilitate analysis of migration levels. This data is available in the file titled Aggregate PLC Summary Data located here. PPL Electric has not reviewed the document provided by the OCA and cannot comment on the document.
43. Q. With regard to the SLAL class hourly load data, can you please explain what this rate class comprised of and how is data for this rate class derived. Also, please explain the intra-day usage differences in the SLAL rate class.
  A. SLAL rate class comprises Street Lighting (SL) and Area Lighting (AL) accounts. In January 2010, PPL Electric converted to using a new meter data management system (MDMS) to track the usage of customers. In regard to the SLAL rate class, there are no actual meters that are used to track the usage, the load data is derived using a sunrise/sunset profile based on number of lights that a customer has and the wattage of each of the lights. In addition, this class also includes a select number of traffic lights which account for the usage in the non-evening hours after 1/1/2010.
44. Q. Do the PPL hourly rate classes represent customers that have opted to take hourly service with the utility as opposed to opting into the fixed price procurement or signing up with a retail service provider?
A. Customers on hourly service with PPL Electric in 2010 are customers in the Large Commercial & Industrial Group who have not opted to receive 2010 fixed price service and who are not taking service from an EGS.  These customers may have opted to take hourly pricing service, or may have failed to affirmatively accept the fixed price POLR service in 2010 within the timeframe to accept the fixed price service and failed to take service with an EGS.  The rate classes of these hourly service customers, for which historical load data are provided, are MP1, MP2, MT1, MT2 and MT3.
45. Q. Was the LP4 class (per 2009 definition) split into LP4 and MP1 starting in 2010?
A. Yes. This is correct. The rate class LP-4 was split into LP-4 for customers receiving fixed price service and MP1 for hourly service customers.
46. Q. ISP and MSP are the only two classes described as "Interruptible Large General Service - 12 kV or Higher," however there is a significant decline in the sum of these two rate classes starting in 2010. There is a sharp increase in the sum of LP5 and MT1 over the same time period. Can you please explain this sudden change in load?
A. Beginning 2010 with the tariff changes, interruptible rates were no longer attractive to the customers. Most customers switched to the fixed rate LP5 or to MT1, which is why the load shifted to those rates.
47. Q. It appears that the load volume for the Residential Class for Mar-Apr-May 2010 is lower than we would have anticipated by about 6%. Can you confirm that there are no problems with the reported load data for the residential class for this period?
A. PPL Electric has confirmed that the data that is posted is the correct load data for that period.
48. Q.

Could you please update file containing PJM deration factors, which appears to be missing data for March 2010.

A. Updated data is now available and posted to the RFP Web site: click here.
49. Q. Can you please provide more detail on what differentiates the individual rate classes for the Large Commercial and Industrial segment? For instance, MT1 and MT2 and MT3 are all described as "Large General Service – 69 KV or Higher (Hourly Price)" and LP5 and LP6 are both described as "Large General Service – 69 KV or Higher."
A. For the Large C&I customer group, rate class LP-5 and LP-6 consists of customers that are taking Large General Service – 69 KV or Higher.  Rate class LP-5 includes customers that are smaller relative to customers in rate class LP-6.  The schedules that start with the letter "M" are the market price (or hourly price) equivalents of the fixed price rate schedules.  Specifically, rate class MT-1 includes customers taking hourly service who would otherwise be in rate class LP-5, rate class MT-2 includes customers taking hourly service who would otherwise be in rate class LP-6, rate class MT-3 includes customers taking hourly service who would otherwise be in rate class IST.
50. Q. With reference to the "rate category and load data" file, it seems as though the data for GS3 and SLAL have been swapped for the month of June 2010.
A. Thanks for bringing this to our attention. This issue has been resolved with the data file that was posted on 10/14/2010.
51. Q. Can you provide Monthly Billed Sales and Monthly Billed Counts for customers within Large C&I customer group that are on fixed price service?
  A. This has been provided on the file that was posted on 10/14/2010.
52. Q. Based on the current data that is provided, if you take that Total LC&I billed sales and subtract Shopping billed sales and Spot LC&I billed sales for August 2010, it implies that 12.5% of LC&I load is on fixed price service. However, the PLC data indicates that 1.5% of LC&I load is on fixed price service. Can you help us reconcile this big difference?
A. PLC data, as found in the Aggregate PLC Summary Data workbook, will not necessarily match billed sales energy usage data because not all customers use energy at the same time and on the same basis.
53. Q. Do you plan on updating the rate category and load data spreadsheet and the Aggregate PLC Summary data files for the April 2011 Solicitation?
A. Yes, the rate category and load data spreadsheet was updated on March 23rd with information up through December 2010 for Aggregate Loads and Feb 2011 for billing data, and the Aggregate PLC Summary data was updated on March 22nd with information up through February 2011.  Subsequent updates will be provided the week of April 11th.
54. Q. Given the reclassification beginning in January 2011 of GS-3 customers greater than 500 KW peak demand and LP-4 customers less than 500 KW peak demand, would PPL now be able to provide hourly load data for the subset of rate class GS-3 and LP-4 customers included in this reclassification?
A. PPL Electric will begin providing this data in the Rate Category and Load data file once January 2011 information has been completely verified (VEE process). We anticipate an update to this file in the week of April 11th.
55. Q. Please provide 2010/2011 and 2011/2012 PLCs by rate class, preferably both on and off-service?  Could you also please provide hourly load data by rate class for on-service customers as well?
A. PPL Electric provides both usage and PLC data found on the Rate Category and Load Data Page (here).  This data is updated at least once prior to each energy auction for potential bidders to use in their independent analysis.  This is the only data PPL Electric is able to provide at this time.
56. Q. The NYPA load data currently provided is through 2008, can you please provide more recent NYPA load?
A. The data is updated through March 31, 2011 and posted here, under "Historical Hourly Load NYPA Supply (.xls)"
57. Q. Could you please explain the significant drop in PLC of customers taking the LCI spot service between 12/29/2010 and 12/30/2010 (from 154 to 71 MW)?  Is the jump in LCI Spot PLCs between 12/31/2010 and 1/1/2011 (from 71 to 96 MW) directly attributable to customers dropping off of the fixed price service and taking spot service on 1/1/2011 by default?
A. The significant drop in LCI Spot PLC was due to a large default customer migrating to an EGS.  You are correct the jump in LCI Spot PLC's from 12/31/2010 to 1/1/2011 is directly attributable to the end of the LCI fixed price option and remaining customers transferring to the spot service.
58. Q. Could you please provide the PLC for PY 11/12?
A. This data has been posted and is available in the Rate Category and Load Data Spreadsheet: click here.
59. Q. Could you please explain to me how should I derive the Default Service load data from the Total system data included in sheets [RS-2008+], [SCI-2008+]
A. PPL Electric is not able to provide comment about how data is analyzed by Suppliers for the purposes of participation in an RFP.  Aggregate load or PLC data is found on the Rate Category & Load Data page (here), as well as on the Rate Category & Load Data .xls file also found on this page.
60. Q. In the file "2011PLCData_Presentation.xls", the non-shopping PLC for SCI decreases by 13% from 701 MW on May 31, 2011 (PY 10/11) to 611 MW (PY 11/12).  However, in the file "rate_category_load_data_21June11.xls", the total SCI PLC increases from 2,032 MW for PY 10/11 to 2,203 MW for PY 11/12, which is an increase of 8.4%. Can you please explain what causes this material difference between the two sets of customers?
A.

The rate category and load data file has PLC data that is for the full load of the PPL territory and is based on the 5 coincidental peaks as determined by PJM. This number is generated off of actual customer usage for the 5 peak hours as determined by PJM and assigned to each customer based on their pro-rata share of that assigned peak.

The PLC data presentation file is a representation of what the actual daily PLC is for those customers that remain on default service. This file was created as a tool that potential suppliers could use to 'forecast' the default service requirements.

The 2 sets of data really do not have any correlation to each other as one is based on a specific period in time while the other is actual data on a daily basis.

61. Q. In the file "2011PLCData_Presentation.xls", the non shopping PLC for residential customers increases by 1.5% from 1,776 MW on May 31, 2011 (PY 10/11) to 1,802 MW (PY 11/12). However in the file "rate_category_load_data_21June11.xls", the total residential PLC decreases from 2,810 MW for PY 10/11 to 2,612 MW for PY 11/12, which is a decrease of 7.0% Can you please explain what causes this material difference between the two sets of customers?

The 2 sets of data really do not have any correlation to each other as one is based on a specific period in time while the other is actual data on a daily basis.

62. Q. Why do the NYPA volumes go negative for a short time period in March 2009?  Is a set schedule of the NYPA volumes given to PPL prior to the month of delivery and if so, will that schedule be provided to the default service provider?
A. The negative values for the short time period in March 2009 was a result of an unknown error, we have looked into it and can not draw any conclusions as to why.  We have reviewed all the data since March of 2009 and have found no additional errors.  PPL Electric does not plan to provide a schedule of NYPA load prior to delivery.
63. Q. As a follow up to Data/General FAQ-60 and FAQ-61, wouldn't the Total PLC = Shopping PLC + non Shopping PLC? While the Total PLC should remain relatively constant over the PJM planning year, the Shopping PLC and non Shopping PLC change based on customer migration.. So based on data provided in the RFP, the residential PLCs decreased by 7% between PY 10/11 and 11/12 and the non Shopping residential PLCs increased by 1.5%. This would imply that the Shopping residential PLCs decreased by 22%. The difference in the year over year change between the two sets of numbers seems very large given that approximately 40% of the residential customers within PPL are shopping. Can you please confirm that this is accurate?
A. The PLCs represented in the data files are correct, as a result of the peak periods that comprise the aggregate PLC.  Additionally, there are other programs that contributed to the decrease in the aggregate PLC from 10/11 PY to 11/12 PY.  As stated in Data/General FAQ-60 and FAQ-61, the NSPL values found in the "Rate Category and Load Data" file can not be directly correlated to "2011 Aggregate PLC Summary Data" file.
64. Q. Please provide the aggregate peak load contribution for the 2011/2012 planning year for the Small C&I load class taking into account the shift of LP4/GS3 customers. 
A. PPL Electric has posted updated data on July 14, 2011. Please refer to the 2011 Aggregate PLC Summary Data file for this information: click here. PPL Electric does not expect to post additional data in advance of the Bid Date for this solicitation.
65. Q. In the answer to Data/General FAQ -38, you mistakenly refer to a 500 MW unit entitlement, but it should be 50 MW. Would you please confirm that this is a mistake?
A. You are correct, this error has been rectified. Only 50 MW is associated with the unit entitlement supply (now known as the Long-Term Product Supply).  
66. Q. Please post hourly load data for the POLR load shares of each customer class. We are a current a PPL POLR supplier and have access to two sets of data: (1) all eligible customer load as reported in the Rate Category and Load Data file, and (2) actual settled load for the tranches of the POLR load we supply.  For the purposes of valuation, we must impute load shapes and volumes for the POLR tranches from the load data provided on the RFP Web site corrected for the implied migration derived from the reported PLC values.  When we do this, we end up with a significantly different value for expected POLR MWhs per tranche from what we are actually settling under our supply arrangement, for the same months. We understand that there might be difference in the effective load factors on the POLR vs. migrated load.  However, the difference appears greater than could be reasonably explained by load factor.
A.

The Rate Category and Load data file has aggregated usage by rate class for all PPL customers. Included in this file is reporting on the retail sales (by rate class) as well as the shopping sales (by rate class). In addition, PPL Electric provides Aggregate PLC data for the POLR load in order to provide additional information to potential suppliers that cannot be derived from the data mentioned above.

PPL Electric Utilities does not see the need to provide any additional data as the forecasting function that companies use to provide their bids should be based on the data that has been provided for all bidders on our Web site, so no additional data will be provided at this time.

The following link provides detail from www.papowerswitch.com on weekly shopping updates as it relates to the load in the PPL Zone. This data may help to refine your modeling used when preparing your bid evaluations.

67. Q. Is the hourly load data shown on the SCI - 2008+ sheet final load (after reconciliation adjustments), or is it preliminary data?
A. Please note that as of 2010, PPL Electric transitioned to a new Meter Data Management System (MDMS). The MDMS provides PPL Electric with hourly data available for all hours, and will use profiles only when the hourly metered data are unavailable. As such, no reconciliation is required on a going forward basis. Prior to the implementation of the MDMS (i.e., prior to 2010), PPL Electric uses the 60-day adjustment primarily to shift load from one supplier to another.  As the historical load data provided is on an aggregate basis by rate class, and there was primarily only one supplier, PPL Electric did not perform a 60-day reconciliation.
68. Q. Please provide historical hourly data broken out by all eligible customers, default service customers, and shopping customers by customer group.
A. PPL Electric has recently posted updated data, including updates to the Rate Categories and Load Data file and to the 2011 Aggregate PLC Summary Data file.  In addition, PPL Electric has posted a file entitled "Supplementary Notes to the Rate Category and Load Data" to provide information regarding updates to the Rate Category and Load Data file. To download the latest data files and supplementary notes: click here. PPL Electric does not expect to post additional data in advance of the Bid Date for this solicitation.
69. Q. With reference to the "Rate Categories and Load Data" file, please confirm that MG-3 and OP-3 rate classes are part of the Large Commercial and Industrial customer group, and L4L rate class is part of the Small Commercial and Industrial customer group. If so, please explain why the MG-3 and OP-3 data is provided in the SC&I tab, and why the L4L data is provided in the LC&I tab.
A. MG-3 and OP-3 are part of the Large Commercial and Industrial customer group, and L4L are part of the Small Commercial and Industrial customer group. The L4L is placed in the LC&I load tab of the "Rate Category and Load Data" file because prior to 1/1/2011, the L4L rate class does not exist and the historical load of the current L4L were included in the historical load of the LP-4 and MP-1 customers. Similarly, the MG3 and OP3 rate classes are placed in the SC&I load tab of the "Rate Category and Load Data" file because prior to 1/1/2011, the MG3 and OP3 rate class does not exist and the historical load of the current MG3 and OP3 were included in the historical load of the GS-3 customers. Prior to 1/1/2011, LP-4, MP-1, GS-3 rate classes include customers less than 500kW as well as customers greater than 500 kW.

Please note that PPL Electric has posted a file entitled "Supplementary Notes to the Rate Category and Load Data" to provide information regarding updates to the Rate Category and Load Data file: click here.
70. Q. With reference to the "Rate Categories and Load Data" file, please confirm that beginning January 1, 2011 hourly data for GS-3 reflects load of customers that have peak load of less than 500 kW (and does not include load of customers with peak load greater than 500 kW).  
A. Yes, beginning January 1, 2011, Hourly load for GS-3 rate class reflects load of all GS-3 rate class customers taking default service and shopping customers that have peak load less than 500 kW.
71. Q. In the "SCI - 2008+" tab of the file "rate_category_load_data_21June11.xls", two new rate classes, TH1 and TH2, began on 1/1/2011. From which preexisting rate classes were these two smaller classes extracted? Can you please map them to existing rate classes before 2011?
A. TH1 and TH2 rate classes, as detailed on the "main" tab of the Rate Category and Load Data file are new classes defined under the Small Commercial & Industrial customer class.  Customers previously on the GH1 rate class that have chosen the Time of Use rate are now placed in the TH1 rate class.  Similarly, GH2 customers that have chosen the Time of Use rate have been placed on the TH2 rate. 
72. Q. Please explain which rate classes did the new L4L rate class belong to prior to 1/1/2011?
A.

Please note that PPL Electric has posted a file entitled "Supplementary Notes to the Rate Category and Load Data" to provide information regarding updates to the Rate Category and Load Data file. To download the latest data files and supplementary notes: click here.

For your convenience, we provide the following summary:

  • On January 1, 2010, the original LP-4 rate class is split into LP-4 and MP-1 rate classes.  Hourly load for revised LP-4 rate class reflects load of customers previously in LP-4 rate class customers taking default service on a Fixed Price basis and shopping customers regardless of size. Hourly load for MP-1 rate class reflects load of customers previously in LP-4 rate class taking hourly default service regardless of size.
  • On January 1, 2011, L4L rate class is introduced. Hourly load for L4L reflects load of customers previously in LP-4 and MP-1 that have peak load of less than 500 kW.
  • L4L is part of the Small Commercial and Industrial customer group.
73. Q. With reference to the "Rate Categories and Load Data" file, please confirm that beginning January 1, 2011 hourly data for LP-4 and MP-1 reflect load of customers that have peak load of equal or greater than 500 kW (and does not include load of customers with peak load less than 500 kW).
A. Yes, beginning January 1, 2011, Hourly load for LP-4 rate class reflects load of customers previously in LP-4 rate class that are shopping customers with peak load equal or greater than 500 KW. Hourly load for MP-1 rate class reflects load of default service customers (equivalent to LP-4 rate class) taking hourly service with peak load greater than 500 kW.
74. Q. With reference to the "Monthly Billed Sales" tab, please confirm that GS-3 customer data contains only data for customers with peak load of less than 500 kW.
A. Beginning January 1, 2011, customers in the preexisting GS-3 rate class that have a peak load equal or greater than 500kW, and that are taking default service or are shopping transitioned to MG-3 and to OP-3, respectively, on the first customer meter read date of 2011. As such, after all customers with peak load equal or greater than 500 kW have transitioned to MG3 and OP3 rate classes, data for GS-3 rate class in the "MonthlyBilledSales" tab reflects data associated with customers with peak load of less than 500 kW only.
75. Q. What causes the Daily Zonal Scaling Factor to be something other than 1.0 on the first day of a new planning period (6/1)?
A. The daily peak load contributions that PPL uploads or schedules to PJM reflect peak loads for the prior year as allocated to individual customers.  PJM changes the load allocated to the PPL zone on the first day of a new planning period (June 1st).  PPL also changes individual customer peak load allocations at that time.  The daily scaling factor is designed to adjust the total PLC assigned to customers to equal the load that was the basis for the amount of capacity purchased for the zone in the PJM eRPM auction in prior years. The value is allocated to the customers that existed in the zone at the time of the prior year 5 coincident peaks, based on their average contribution to the peak load day. There are changes in customers between the time of the PJM peaks due to customers ending service and new customers coming on the system (which typically are assigned default values). As a result the initial scaling factor reflects a reduction (if less than 1.0) or an increase (if greater than 1.0) in the assigned PLC values through the year.

(This response was revised on December 28, 2011.  The original responses previously stated that individual customer peak load allocations were not updated on June 1st in error.)
76. Q. What time zone is the load data in? 
A. The load data provided is in Eastern Prevailing Time.
77. Q. Can you provide shopping and non-shopping NSPL values by customer type?
A. No, PPL Electric does not currently have this information readily available.
78. Q. Why is MG-3 and OP-3 (GS-3>=500kW) listed on the tab for SCI when it is actually LC&I? Also, why is L4-L listed on the tab for LCI when it is actually SC&I?
A. Please see Data/General FAQ-69  for this information.
79. Q. Is data available to differentiate hourly default service and shopping load for GS3 and L4L?
A. The information you requested is not readily available. PPL Electric has provided, in the Aggregate PLC Summary Data file, aggregate PLC values per customer group for POLR customers to help facilitate analysis of migration levels. This data is an estimate of PLC by customer group and is only a snapshot in time.
80. Q. The PPL daily zonal scaling factors posted on the PJM Web site show a material increase from 0.921 on August 19, 2011 to 0.955 on August 20, 2011. There is another increase from 0.954 on August 31, 2011 to 0.989 on September 1, 2011. What has caused this increase of over 7% in the daily zonal scaling factors between mid-August and September 2011 given that the UCAP allocated to PPL zone is fixed for PY 11/12 and the customer PLCs remain fixed for the same time period?
A.

During a review of customer Peak Load Contributions (PLCs), PPL Electric Utilities (PPL Electric) identified an erroneous ICAP PLC value for a residential account.  Specifically, a PLC value was erroneously input as 246.1 MW (versus 2.46137kW).  The error went undetected during the 80 day period beginning 6/1/2011 through 8/19/2011.  An error of this magnitude resulted in a significant change in the PPL Electric Daily Scaling Factor.  To correct the error, PPL Electric will reduce the aggregated ICAP PLC values reported to PJM for the impacted supplier by 246.1 MW for an 80 day period starting 9/1/2011 and ending 11/19/2011.  This correction will result in a change in PPL Electric's Daily Scaling Factors for all suppliers during this period.  Please take note of our estimate of how this correction will impact PPL Electric's Daily Scaling Factor:

  • During the time the error existed (6/1/2011 to 8/19/2011), the PPL Electric Daily Scaling Factor was approximately 0.92.
  • After the incorrect PLC was corrected (on 8/20/2011), the PPL Electric Daily Scaling Factor increased to a more appropriate level of approximately 0.95.
  • Starting 9/1/2011, PPL will apply the correction discussed above for an 80 day period.  During this time, the PPL Electric Daily Scaling Factor will increase to approximately 0.98.

After the correction period is finished (11/20/2011), the PPL Electric Daily Scaling Factor will return to a value of approximately 0.95.

81. Q. With reference to Data/General FAQ-80, due to the reduction of one residential customer's PLC from 246.1 MW to 2.46kW, will the total residential PLC in the file "rate_category_load_data_30aug11.xls" decrease from 2,611.6 to 2,356.5? If this is the case, then residential PLCs decreased by 16% between PY 10/11 and PY 11/12. Given that the PLCs for the non-shopping customers increased between the PY 10/11 and PY 11/12, the drop in PLCs for the shopping customers is even more pronounced. Can you explain why there is such a large drop in PY 11/12 PLCs for the total residential and shopping residential customers?
A. The PLC as stated in the rate category and load file is correct.  The error in the reporting was for current PJM submissions only.
82. Q. When does PPL change individual customer peak load allocations?
A. PPL Electric changes the individual customer peak load allocations on June 1st and the customer Transmission (NITS) value on January 1st of every year in order to coincide with PJM practices.

Please refer to Data/General FAQ-75
83. Q. Please provide the 2012 NSPL data and PLC data.
A. The 2012 NSPL has been posted. To download the latest data files and supplementary notes: click here. PPL Electric does not expect to post additional data in advance of the Bid Date for this solicitation.
84. Q. Could you please explain the steady decline in monthly billed counts for both the GH-1 and GH-2 classes? Is this decline in eligible customers due to a rate class reclassification?
A. The decline is due to an increase in shopping in the Small C&I customer class.
85. Q. Can you confirm that the Historical PLC data provided in the “Rate Categories and Load Data” for Small C&I includes only customers Less Than 500 kW?
A. The Historical PLC data provided in the “Rate Categories and Load Data” for Small C&I is based on rate schedules, and does not account for the revised definitions used in the current Default Service Procurement Plan. In particular, the PLC provided for the Small C&I Customer Group excludes LP-4 customers with peak demand less than 500kW, and includes GS-3 Customers with peak demand greater than 500kW.
86. Q. Could PPL please provide Planning Year 12/13 PLCs and NSPLs broken out by shopping and non-shopping customers as of a specific date?
A. This information is not available at this time.
87. Q. With reference to the following data provided by pjm (click here) and comparing it to data provided by PPL Electric (ie., the “Rate Category and Load Data”), the sum of the Res, SCI, and LCI customer class PLCs plus the aggregate PLC from UGI are very close to the PLC allocated to PLCO zone by PJM.  Could you please explain why there has historically been a daily zonal scaling factor of something far less than 1 (.9238 for June 1st, 2011; .9665 for June 1st, 2010; .9634 for June 1st, 2009, etc.) according to the DZSF posted on the PJM website?  Given the consistency of the zonal peaks from year to year, it appears inconsistent that the DZSF is less than 1 by such a magnitude.  Does PPL have any expectation that the DZSF will not return to 1 beginning June 1st, 2012?
A. During a review of customer Peak Load Contributions (PLCs), PPL Electric Utilities (PPL Electric) identified an erroneous ICAP PLC value for a residential account.  Specifically, a PLC value was erroneously input as 246.1 MW (versus 2.46137kW).  The error went undetected during the 80 day period beginning 6/1/2011 through 8/19/2011.  An error of this magnitude resulted in a significant change in the PPL Electric Daily Scaling Factor.  To correct the error, PPL Electric will reduce the aggregated ICAP PLC values reported to PJM for the impacted supplier by 246.1 MW for an 80 day period starting 9/1/2011 and ending 11/19/2011.  This correction resulted in a change in PPL Electric's Daily Scaling Factors for all suppliers during this period. After the correction was completed the daily scaling factor returned to a more normal range of 0.95.
88. Q. Could you please update the PLC tags for June 1, 2012 forward?
A. The PLC tags for June, 2012 moving forward have been posted. Please note that these are estimates only and that the finalized tags for each month are posted shortly after the month is completed.
89. Q. On the SCI - 2008+ tab in the Rate Categories and Load data file posted as of June 26, 2012, the sum of the individual rate schedules (column C through L) equalled the total SCI (column M) through March 31, 2012. However, beginning on April 1, 2012the sum of the individual schedules in columns C through L does not equal the total (column M). Is there a reason for this, or is this an error?
A. The sums were not updated properly for the categories reported. The file has been corrected and re-posted.
90. Q. On Page 10 of the PPL Electric Default Service RFP for Full Requirements products, you have forecasted PLCs for January 2011 to May 2011 and June 2011 to December 2011.   Will you be able to provide us with the forecasted PLC for June 2012 to June 2013?
A. No. PPL Electric does not have this information readily available. Please also see Data/General FAQ-4 for additional information.
91. Q. PJM's Network Service Peak load for PPL for 2012 (July 22, 2011, Hour 14) shows 7737.5 MW.  However, the sum of the LCI, SCI, and Residential loads provided in the “Rate Category and Load Data” file that you supplied for July 22, 2011 (Hour 14) equals 7311 MW.  Can you please explain this discrepancy?
A. PJM’s NSPL is the average of the 5 peak loads on the PPL system, therefore, any single hour chosen from the Rate Category & Load Data file will not equal the assigned peak.
92. Q. Does PPL have interval metering for all customers (Residential, Small Commercial & Industrial, and Large Commercial & Industrial)?  If so, what data was it implemented for all customers?
A. PPL Electric transitioned to a new Meter Data Management System (MDMS) in 2009, which became fully functional in January 2010. The MDMS provides PPL Electric with hourly data available for all hours, and PPL Electric will use profiles only when the hourly metered data are unavailable.

With the exception of a few customers, hourly meters are installed at almost all customer sites. Please see Data/General-43 and 67 for information.
93. Q. Will the paths associated with the auction revenue rights (ARRs) be provided?
A. No.
94. Q. Can you explain the reason for the drop in the Small Commercial & Industrial PLC from May 2012 (640) to June 2012 (485)?
A. 6/1/2012 was the introduction of 2012/2013 Planning year ICAP tags. The new allocation of PLC is the reason for the change from month-to-month.
95. Q. In the file “2012PLCData_Presentation_070512.xls” the Small C&I Default Service PLC (daily) decreases from 640 MW on May 31, 2012 to 480 MW on June 1, 2012.

The corresponding PLC (annual) for all Small C&I customers, located in the file “rate_category_load_data_07102012.xls”, decreases from 2,202.9 MW to 2,166.6 MW over the two planning years. Can you please explain why the Small C&I Default Service PLCs show a decline of 25% whereas the total Small C&I PLCs on drop by 2%?

In the file “2012PLCData_Presentation_070512.xls” the Residential Default Service PLC (including the Block) decreases from 1,779 MW on May 31, 2012 to 1,701 MW on June 1, 2012. The corresponding PLC (annual) for all Residential customers, located in the file “rate_category_load_data_07102012.xls”, increases from 2,611.6 MW to 2,838 over the two planning years. Can you please explain why the Residential Default Service PLCs show a decline of 4% whereas the total Residential PLCs on increase by 9%?
A. The PLC allocation to customers is based on the customer’s actual meter reads on the PJM peak days assigned in the PPL Zone. Customers are assigned their proportionate share of the load based on their contribution to the peak. In June 2012 the new PJM Planning Year PLC values were assigned to customers. The total Residential PLC increased year-over-year but the Default Service amount declined due to the aggregation of the customers remaining on default providing less of the peak than the previous year. The same methodology to PLC allocation applies to the Small C&I group.
96. Q. Is there a method to enable automated retrieval of the PLC tags? It seems that navigating to the website and manually copying an excel file is a bit cumbersome, especially with the frequent changes in load due to shopping. Does PPL EU have or will they develop and XML interface or FTP Server for this?
A. No, there is not a method to enable automated retrieval of the PLC tags at this time. PPL Electric does not expect to develop an interface for this purpose during the course of this solicitation.
97. Q. 

With respect to the Rate Categories and Load Data file, on the SCI - 2008+ tab, the sum of the columns for the individual rate schedules (C – L) does not equal the total column (M). Is this a mistake?

  A. 

The total column M in the Rate Categories and Load data file for the Small C&I class has been corrected to equal the sum of the columns C-L.

The corrected file was posted on October 5, 2012. 

98. Q. 

The PJM Deration Factors file is missing data for May 31, 2012.  Is this a mistake? 

  A.

Thank you for identifying this error.  The file has been corrected and reposted on October 5, 2012.

99.  Q.

With respect to the 2012 Aggregate PLC Summary Data file, why did the PLC for the Small C&I Class double from August 2012 to September 2012? Is this a mistake?  

  A.  Thank you for identifying this error.  The file has been corrected and reposted on October 5, 2012. 
100.  Q.

When will PPL Electric update data for this October 2012 solicitation?

  A.  On October 5, 2012, PPL Electric has posted the following data files:

The Rate Categories and Load Data file (through August 31, 2012): click here.

The PJM Deration Factors file (through August 31, 2012): click here.

The 2012 Aggregate PLC Summary Data file (final values through September 23, 2012): click here.

The Historical Hourly Load NYPA Supply file (through August 31, 2012). Additionally, in the Historical Hourly Load NYPA Supply file, PPL Electric has added a new tab providing historical NYPA Capacity values: click here.

PPL Electric does not expect to post additional data prior to the Bid Date of October 16, 2012.

101.  Q.

How is the Network Service Peak Load calculated? How are the peak days determined? Do you have a spreadsheet that shows this calculation? 

  A.

Please see Data/General FAQ-40. The NSPL provided in the Rate Category and Load Data file is calculated as an annual value associated with the PPL Zone and is scaled up or down based on customer changes to match the target NSPL value calculated on an annual basis.

Additional data are not readily available and will not be provided at this time. 

102.  Q.  On the "Capacity" tab of the rate-category-load-data.xls file, there is a note stating that "Historical PLC data is based on rate schedule not the new definition of Small vs Large Commercial and Industrial."  Does this note apply to the 2012 planning period as well?  Specifically, for the 2012 planning period, the PLC was based on the 2011 summer which would have been after the new class definitions were instituted and we are concerned that the SCI PLC of 2,166.6 does not in fact need to be adjusted for the class changes.
  A.  The current note does not apply to the 2012 planning period data.  The footnote in the “Capacity tab” of the “rate-category-load-data“ file will be updated to state the following: Prior to the 2012 planning period, Historical PLC data is based on rate schedule not the new definition of Small vs Large Commercial and Industrial. 
103.  Q. With regard to the ‘Rate Category and Load Data’ file, can you provide a spreadsheet example of how you allocate the Network Service Peak Load (NSPL) between the classes (Residential, Small C&I, Large C&I, and FERC wholesale)?
  A. NSPL per customer class (Residential, Small C&I, and Large C&I) is based upon the sum of each individual customers load for that class.  To gain a better understanding of how a customers PLC is calculated, please see the following presentation.
104.  Q.  With regard to the ‘2012 Aggregate PLC Summary Data’ file, the PLC values for the Residential Class for September and October look incorrect. Can you please confirm that the posted data is correct? 
  A.  The values found in the 2012 Aggregate PLC Summary Data table are correct for the months of September and October.  The data was re-run to ensure accuracy, which was reaffirmed.  For these months there was very little movement in customer load. 
105.  Q.  Can you confirm that when you mention that loads are adjusted for losses to the zonal aggregate load bus, you mean de-rated load at the PJM settlement level? 
  A.  Please see Data/Full Requirements FAQ-1 and FAQ-2 for information. 
106.  Q.  With regard to the ‘Rate Category and Load Data’ file, will you be providing hourly customer load data for October 2012, November 2012, and December 2012 before the January 22, 2013 Bid Date? 
  A.  With reference to the “Rate Categories and Load Data” file, PPL Electric expects to update this file with hourly load data up through October 2012 and with monthly sales and customer count information up through December 2012.  PPL Electric anticipates an update to this file in the week of January 14. 
107.  Q. How do you allocate the NYPA capacity and energy between the Residential, Small C&I, and Large C&I?
  A.  Please see Contracts/Full Requirements FAQs-12, 2425 and 26
108. Q.  With reference to note 1 in this file, can you explain what "Interruptioned Load Added Back" means?
  A. The “Interruptioned Load Added Back” term represents load associated with customer participating in the PJM Demand Management program that is added back into the total load number; whereby, if a customer was interrupted during one of the 5 Coincidental Peak periods through participation in the program (thus reducing their load) and is summarily paid for the interruption, their load is added back into the total, as found on this file, to ensure the same customer is not double-compensated and all load totals are accurate.
109. Q. The Presentation does not give a numerical example of how the Transmission PLC is allocated between Classes. Can you please provide an example based on Planning Year 2011/2012 data?
  A. PPL Electric refers to Network Service Peak Load (NSPL) and Network Integration Transmission Service (NITS) interchangeably, as referenced in the Rate Category & Load Data file. Similarly, PJM often refers to NSPL as Transmission PLC. Each term is interchangeable as represented by the presentation. Please see the Rate Category and Load Data file for information: click here.
110. Q. When reviewing the Shopping Billed Sales data provided in the Rate Category & Load Data file, energy migration for the Residential Class seems to increase much more rapidly than the Residential PLC. There are periods when the Residential PLC did not change by much, but the Shopped Billing Sales for the same period changed significantly. Why does this happen?
  A. The “Shopping Billed Sales” data found in the “Rate Category & Load Data” file is based upon actual shopping load data pulled from customer meters and aggregated by rate category. Furthermore, this load is aggregated by month. PLC data as found on the Aggregate PLC Summary Data files is based upon an estimated Default Service Load as submitted to PJM, by date. The PLC data is only an estimate at a point in time and does not necessarily correlate directly to monthly sales figures due to reconciliation, weather normalization, error corrects, etc. Furthermore, billed sales figures are based upon a customer’s billing month (not necessarily aligned with a calendar month), and aggregated as such – whereas, PLC data is a point in time estimate for that exact date, regardless of customer billing period. As such, “shopping billed sales” figures may have greater volatility and/or be disjointed from the values found in the estimated PLC data.
111. Q. In reference to the “Rate Categories and Load Data” file, why doesn’t the value for Monthly Billed Sales (provided on the monthlybilledsales tab) for 8/1/2012 for the residential class equal the hourly load for the residential class (provided on the RS-2008+ tab) for the month of August 2012?
  A. There are a variety of reasons while monthly billed sales at the retail meter times the loss factors do not yield the same value as the sum of hourly loads at the generation level. These include the fact that loss factors are average loss factors and that losses in some months may be higher or lower than that implied by the loss factors. However, the primary reason for the difference is that the comparison you are making is for different time frames. Monthly billed sales reflect what PPL Electric Utilities is billing each month and includes usage of the customer in the prior month. For example, billed sales for a bill issued on May 3, will be all counted toward May monthly billed sales, even though the usage occurred mainly in April and would be included mainly in April hourly loads. Monthly billed sales for any month reflect the billing cycle and generally reflect usage over the current and prior month, with different proportions for each customer depending on when a customer's bill is issued. There is no calculation that will align monthly billed sales and hourly loads.
112. Q. Can you post the historical daily zonal scaling factors?
  A.

Historical daily zonal scaling factors are provided by delivery year under the relevant drop down boxes on the PJM Web site here. This information is also available from eRPM through eSuites on the PJM Web site.

Additional scaling factors are not readily available and will not be able to be provided at this time.

113. Q. Would you please provide the PLC value for Planning Year 2013/2014 for the residential and Small C&I classes?
  A. PPL Electric is currently working on aggregating PLC values by customer class for display within the Rate Category & Load Data file. This is expected to be finalized by the end of January 2013. It is not likely this will be completed prior to the Bid Proposal Due Date of January 22, 2013.
114. Q. In reference to the 2012 Aggregate PLC Summary Data file for September 2012, why does the Residential PLC fluctuate from 1337 to 1330 and then back to 1337?
  A. PLC data found in the Aggregate PLC Summary Data file is pulled directly from the PJM eRPM system and represents actual PLC by customer class. The load fluctuations from day to day in any particular month are a factor of customer migration, customer usage, weather and other similar impacting events. There was no unique event that occurred resulting in the fluctuation found during the month of September 2012.
115. Q. If the variance in the PLC for the month of September 2012 was due to customer migration, customer usage, weather, etc, as provided in Data/General FAQ-114, then why is the value just fluctuating from 1337 to 1330 and then back to 1337?
  A. PPL Electric is not able to provide comment about how data is analyzed by suppliers for the purposes of participation in an RFP. Aggregate load or PLC data is found on the Rate Category & Load Data page (here), as well as on the Rate Category & Load Data .xls file also found on this page.
116. Q. Why does the sum of the capacity obligations for each Class provided in the rate categories and load data file from November 27, 2012 (Residential = 2838, Small C&I = 2166.6, LC&I = 1690) not equal to the capacity obligation for the PPL Electric zone (6890) provided on the PJM website here?
  A. There are two reasons that the two data sets referenced are not matching. First, the capacity values referenced on the Rate Category & Load Data file are 2012 Planning Year values (based on 2011 data); whereas, the PJM referenced file is 2013 values (based on 2012 data). In short, the data sets are for two different years. Second, the data found in the Rate Category & Load Data file does not include FERC Wholesale load, while the PJM file does include that load. FERC Wholesale load equates to approximately 185 MW for both Planning Year 2012 and Planning Year 2013. For these reasons, the two data sets will not match.
117. Q.

In the column RTO Coincident Peaks in the table below, I provide the PJM 2011 and 2012 Summer Weather Normalized RTO Coincident Peaks from the PJM web site. Is the difference between the PJM information and the Total Peak Load Responsibility (“PLR”) data provided in the Rate Categories and Load Data file due to FERC Wholesale Load? Where can I get the FERC Wholesale Load value?

PJM Planning Period PLR Residential PLR Small C&I PLR Large C&I Total PLR RTO Coincident Peaks
2011 2,611.60 2,202.90 1,855.50 6,670.00 6,700.00
2012 2,838.00 2,166.60 1,690.00 6,694.60 6,880.00
  A. As explained in Data/General FAQ-116, the difference between the values given is a factor of both a lack of FERC Wholesale values being included in the Capacity Obligation as represented in the Rate Category & Load Data file, and differing Planning Periods. PPL Electric does not display the FERC Wholesale value on the Capacity tab of the Rate Category & Load Data file; however, this value can be tabulated by subtracting the correct total capacity amount in this file from the PJM file previously referenced. Updated 2013 PJM Planning Period Capacity Values are expected to be issued by the end of January 2013; however, they are not likely to be issued in time for the January 22, 2013 Bid Proposal Due Date.

Load Following Full Requirements
1. Q.

Are the historical load data provided on the RFP Web site de-rated for marginal losses?

  A. No. Historical load data provided on the RFP Web site are not de-rated for marginal losses. However, hourly loss duration factors are provided on the RFP Web site so that each supplier may perform this calculation.
2. Q. Will suppliers be responsible for hourly loss de-rated load, and be paid for this level of load? 
A. Yes. For settlement purposes, suppliers will be responsible for the hourly loss de-rated load, and will be paid by PPL Electric for this hourly loss de-rated load. 
3. Q. To clarify the definition of energy supply equal to hourly loss de-rated load, is this the same load as defined by PJM reports of "Load without Losses?" 
A. The "Market Settlement Overview" on the PJM Web site indicates on page 99 that many billing items including spot market energy, congestion and reserve obligations are settled on what PJM calls "lossless load." Other items such as capacity obligation and Network Transmission Service are settled on what PJM calls "Load + Losses." PPL Electric reports to PJM hourly loads that include all applicable transmission and distribution losses. To access these hourly load data: click here. PJM derates these losses by marginal loss de-ration factors to derive settlement loads for spot market energy, congestion, reserve obligations and other items as indicated on page 99 of the referenced document. To access the marginal loss deration factors: click here. These loads, which include all losses and are de-rated for marginal losses, are the basis for PJM settlement and the basis for payment under the PPL Electric master agreements. It hence seems plausible that what PJM reports as "Load without Losses" is equivalent to load de-rated for marginal losses, but we have not been able to confirm that. We suggest that you contact PJM to confirm that what they report as "Load without Losses" is equivalent to the load de-rated for marginal losses.
4. Q. If supplier delivers 100 MW, is that supplier paid for 100 MW?
A. PPL Electric Utilities will report to PJM loads that include all distribution and transmission losses (including PJM assigned 500 kV losses and unaccounted for energy). PJM will loss derate those loads for settlement purposes. For settlement purposes, suppliers will be responsible for the hourly loss de-rated load, and will be paid by PPL Electric for this hourly loss de-rated load. If the hourly loss derated load for your tranches is 100 MW in an hour you will be required to deliver 100 MW and will be paid for 100 MW.
5. Q. In Full Requirements RFP Rules, the PLC (MW) for the Residential Customer Group are 3765 (01/01/11-05/31/11) and 3585 (06/01/11-12/31/11). Are these PLCs excluding 300 MW block supply contracts and up to an additional 50 MW of long-term unit entitlement supply contract or including both of them? For January-May, 2011, is the obligation 3765 or 3765-300 = 3465?
A.

The PLC (MW) for the Residential Customer Group as provided in the Full Requirements RFP Rules is for the entire Residential Customer Group.

Please note that these numbers are 'forecasts' or projections of PLCs, and will change to match actual peak load contributions once actual supply begins at the commencement of the supply period. For historical PLC data please see the Rate Category & Load Data from 2001 to present found here.

Please also see Data/General FAQ-4 and Data/General FAQ-15 for additional information.

6. Q. The forecast PLCs of the Residential Group as provided in Full Requirements RFP Rules is significantly higher than the current and historical PLCs even considering load growth rate. How are the forecast PLCs in Full Requirements RFP Rules for the Residential Group estimated?
A. Please refer to Data/General FAQ-4 and Data/General FAQ-15 for information related to your question.  PPL Electric would like to emphasize that all of the PLCs provided in the Full Requirements RFP Rules are "forecast" values, based upon a litany of assumptions, and therefore will change to match actual peak load once supply begins.  Also available are historic PLC values found in the "Rate Category and Load Data" workbook on PPL's DSPP Site, which show changes and variations in PPL Zone PLC from year to year, from 2004 to 2008. 
7. Q. The 2011 projected PLC as provided in the RFP Rules is 3585-3765 MW. Does this include long-term supply from NYPA, 300 MW block energy RFP, and up to 50 MW unit entitlement supply? In other words, to derive the load per tranche, before I apply the tranche size, do I need to deduct NYPA supply, the 300 MW from the Block Supply RFP, and unit entitlement supply from my total load forecast?
A.

The PLC (MW) for the Residential Customer Group as provided in the Full Requirements RFP Rules is for the entire Residential Customer Group including the portions to be served by long-term supply from NYPA, by the 300 MW block energy RFP, and by the 50 MW unit entitlement supply.

Please note that these numbers are 'forecasts' or projections of PLCs, and will change to match actual peak load contributions once actual supply begins at the commencement of the supply period. For historical PLC data please see the Rate Category & Load Data from 2001 to present: found here. For historical data related to the NYPA supply, please see the Historical NYPA Load Hourly Supply file: found here.

Please also see Data/General FAQ-4 and Data/General FAQ-15 for additional information.

 8. Q. In reference to the Capacity tab in the Historical Hourly Load NYPA Supply file,  how does PPL Electric calculate the NITS and ICAP values for 1/1/2012 - 12/31/2012? Are these values already known? Do you know the values for 1/1/2012 - 12/31/2013? 
  A. The NITS values staring 1/1/2013 and ICAP values starting 6/1/2013 are calculated based upon the amount of load served by the NYPA generation allocation to PPL Electric at the time of the previous year’s 5 peak days (CP).  These values are equivalent to a customer’s PLC value.  This methodology was implemented to reduce issues associated with the differences between the two cycles (NITS running 1/1-12/31 annually and ICAP running 6/1 – 5/31 annually).  Previously ( NITS: 12/31/2012 and older; ICAP: 5/31/2013 and older) ICAP and NITS were calculated to match the load allocation from Allegheny Energy to PPL Electric for the upcoming year.
