Retail Competition Background:

The 1997 Electricity Generation Choice and Competition Act, allowed residential customers to have direct access to and purchase power from independent EGSs, while still having their electricity physically delivered by electric distribution companies (EDCs) regulated by the PUC. The law also permitted the EDCs to recover “stranded costs.” Stranded costs include investments in infrastructure made before the law was passed that may have become uneconomic and unrecoverable in a competitive environment. With limited exceptions, once rate caps expired, the companies could no longer collect for stranded costs. In exchange for the recovery of stranded costs, generation, transmission and distribution rates were capped at 1996 levels. The caps on transmission and distribution rates all have expired as of Jan 1, 2011.

The Pennsylvania Public Utility Commission (PUC) launched the Standard Offer Program (Standard Offer) in August 2013 to give non-shopping customers greater access to the competitive electricity market and its benefits. Standard Offer is voluntary, and made available to all residential and small business customers by electric distribution companies (EDCs) that have competitive suppliers actively participating in their program at a given time. Depending upon market conditions, Standard Offer may not always be available in all areas. Prior to Standard Offer, non-shopping customers remained on the sidelines, giving up their right to choose a supplier, take advantage of dozens of new products on the market and potentially save on their monthly bills. Standard Offer is a “win-win” for the electric shopper and supplier alike. The customer wins with potential savings on electric generation over the course of a year, with little or no risk, while the supplier gains a new customer now actively participating in the competitive retail market.

The PUC requires electric utilities to refer certain customers calling the utility (such as customers with a high bill complaints) to a randomly selected retail electric supplier participating in Standard Offer. The supplier, or a third-party acting on behalf of the supplier, must make the Standard Offer, which includes a fixed-rate price, 7 percent below the electric utility’s current Price to Compare (PTC, the price the utility pays for electricity), for a term of one-year with no cancellation or termination fees. A Standard Offer customer can cancel the agreement at any time.


  • With Pennsylvania’s new accelerated switching rules, most Pennsylvania customers can be switched to their new supplier in three (3) business days once the electric utility is notified of the switch by the supplier.  If the utility does NOT have accelerated switching, the effective date of service with the new supplier depends on the customer’s next meter read date and can take 11 to 40 days.
  • The price to compare (PTC) is the price per kilowatt hour (kWh) your electric distribution company (EDC) will charge and includes: charges for generation and transmission; the state’s gross receipts tax; and the utility’s charges for implementation of the Alternative Energy Portfolio Standards (AEPS).  Under the law, an EDC’s PTC may be adjusted quarterly but is not seasonal. An EDC develops its PTC based on what the company pays for electricity during auctions held over a two-year period on the wholesale energy market.
  • In most cases, you should be able to receive a single monthly bill from your electric utility. However, some suppliers might want to bill you separately. In this case, you would receive two bills, one from your electric utility and one from the supplier.
  • Since 2004, the Pennsylvania Public Utility Commission (PA PUC) has been working to implement the Alternative Energy Portfolio Standards Act (AEPS), which encourages reliance on more environmentally friendly sources of energy and helps consumers take control of their energy requirements. AEPS requires that a certain percentage of all electric energy sold to retail customers come from alternative energy sources, such as solar, wind and hydropower.
