Firm or Interruptible Power
Industrial and commercial customers with firm or interruptible power requirements can benefit from DSIR; as long as they have a monthly maximum demand of at least 1,000 kw year-round and currently are on the LP-4, LP-5, LP6, IS-P, or IS-T Rate Schedules.
By 5 p.m. each day, PPL Electric Utilities transmits to DSIR customers 24 hourly market prices that will be in effect starting at midnight for the next day. These market prices are for planning purposes only. The actual bill will be based on a market price that is derived from the PJM Locational Marginal Price (LMP) for the PPL Electric Utilities zone.
The price forecast is transmitted through a secured Internal Web site (PPLLink). The customer can then decide how to schedule operations based on the market prices for electricity for the following day.
Interruptible customers are required to interrupt in accordance with the Optional Interruptible Power provision of rate schedule IS-P or IS-T. During an interruption, the DSIR customer's CRL is reduced to the contracted firm power level, after a two-hour notice.
