Frequently Asked Questions

Are there application fees for interconnection requests? If so, how are they structured?
Effective Sept. 3, 2019, there will be an application fee for all new Distributed Energy Resources-Renewable Energy (DER) interconnection applications. Application fees will vary from $100 to $350 depending on the size and type of proposed generation. Larger systems have an additional fee per kilowatt. For systems that qualify for net metering, the standard fees outlined in the Public Utility Commission Policy Statement on Interconnection Application Fees were adopted in 2009. These fees are:


Brief Description

Base Fee

Per kW Fee


Certified inverter-based installations of 10kW or less.




Certified inverter-based installations greater than 10kW but 2000kW or less.



3 and 4

Non-inverter-based installations of any size.

Certified inverter-based installations larger than 2000kW.



Are the kW nameplates based upon the AC or DC ratings?
The kW nameplates are based on the net maximum or net instantaneous peak electric output capacity measured in AC (volt-amps) of the generator facility.

Are there any other costs to connect?
There may be costs to connect, depending on the customer equipment size and location. The customer would have to pay PPL Electric Utilities for any upgrades to our system that may be needed to connect their renewable energy source to the grid. The customer also may need to purchase and install additional equipment other than the renewable energy facilities.

What forms of payment are accepted for the Application Fee?
At this time, only a bank transfer or check payment are accepted, but we will consider other forms of payment in the future.

Will my supplier compensate me for the electricity I produce?
If you have a different supplier, ask if or how you will be compensated. Not all electricity suppliers participate in net metering, and may not compensate customers.

Will solar panels provide emergency power during a power outage?
No. By design, solar inverters must disconnect from the power grid if an outage occurs. This isolation is incorporated as a safety feature to protect your equipment from overloading and to protect electric service personnel.

Could generation systems be modified to supply power during a power outage?
System options for generation include “break before make” transfer switching and battery backup systems. These options are already incorporated on some units and could be added on some existing systems for additional cost.

How will PPL Electric Utilities know how much power I produced?
PPL does not know how much power you produced. If the system is producing more electricity than the household is using, then our meter will record how much electricity we receive from you. We don’t measure the total amount of electricity you produce and how much of that energy you use before returning it to the grid.

Will I be paid for excess power?
Payments for customers on rate schedules RS and GS1 will be based on the Price to Compare in accordance with PUC regulations. Customers on rate schedules GS3 or LP4 may contact Business Accounts regarding compensation for excess generation.

How much will I be paid for excess power?
Between settlement periods, excess kilowatt-hours produced are carried forward and applied at full retail value, kilowatt-hour for kilowatt-hours, to offset your usage. At a settlement point in May, your compensation will be dictated by whether you have selected an alternate generation supplier or rely on PPL Electric Utilities to buy power on your behalf.

Will I still get an electric bill if I generate my own power?
Yes. You will continue to receive bill statements from us and will be responsible for the monthly minimum distribution charge that applies to your rate class (see PPL Electric Utilities’ tariff.) Demand charges may apply for GS-1 and GS-3 rate customers. We need to have the same power lines, metering equipment and facilities in place to serve you — whether we’re needed as a backup source of supply or to take and distribute excess power that you produce. The minimum monthly charge, or customer charge, covers a portion of our costs to provide and maintain this equipment. Other charges may apply in certain circumstances.

How do I begin the interconnection process?
Visit the Renewable Energy Connection, an industry-leading online portal designed with customer feedback that lets you easily apply to connect your solar panels or other distributed generation project. Once you’re signed in, click Start New Work Order, then Start Work Order. Select “Distributed Generation” as the type of application you’re submitting.

What is required for the interconnection process?
The interconnection, when complete, must not jeopardize the safety of our workers or the public, and must not compromise the reliability of the electric grid. There are two steps to connecting your distributed generation project to the grid: The online application, which should be submitted before installation, and then the Certificate of Completion. For the online application, customers must answer questions about their system, generation capacity, and technical information about inverters and batteries. Documents required to be uploaded include the one-line diagram, site plan, equipment data sheet, and Appendix A (“Terms and Conditions”). Once the application is approved, you may install your system. Once completed, please submit the Certificate of Completion via email. For systems under 25 kW, email For systems over 25 kW, email PPL will then reply with final approval.

Must I sign a contract?
Yes. You must electronically sign an interconnection agreement with PPL Electric Utilities. Additional service and construction agreements may be required for larger projects under the jurisdiction of PJM Interconnection.

Does PPL Electric Utilities provide generation equipment or installation services?
We supply the metering equipment required for billing purposes. You are responsible for generation equipment and installation.

May I sell power to my neighbor?
No. Only licensed electric generation suppliers subject to Pennsylvania Public Utility Commission regulations may sell power to a third party.
