Welcome to the Pennsylvania Alternative Energy Portfolio Standard Program website

The Pennsylvania Alternative Energy Portfolio Standard (AEPS) requires that an annually increasing percentage of electricity sold to retail customers in Pennsylvania is from alternative energy sources. The program requires that retail energy suppliers utilize Alternative Energy Credits (AECs) for demonstrating compliance with the standard. An AEC is created each time a qualified alternative energy facility produces 1000 kWh of electricity. The AEC is then be sold or traded separately from the power. This makes it easy for individuals and businesses to finance and invest in clean, emission free solar power.

This website:

To be qualified as an alternative energy facility under this program, an application must be submitted. Once your application is approved, you will be able to generate AECs under this program. Please follow the instructions for submitting your application to qualify your facility.

For alternative energy facilities that are interconnected to the PJM or MISO transmission system, your AECs will be deposited directly into your PJM-GATS account once your application has been approved and your facility has been accepted into the program.

For facilities that are not interconnected to the transmission system (customer-owned systems and energy efficiency/demand-side management measures primarily), you can manage your AECs through this website. If you are a customer-owned generator, such as a small solar, wind, or landfill gas facility, this AEPS Program provides a means for AECs to be tracked within the account you create. You will need to create an account and submit an application for your facility in order to receive a certification number. All certificates are created in the PJM-GATS system and traded within that platform, and you will therefore need an account within the PJM-GATS system as well. If you are represented by an aggregator, a PJM-GATS account is not necessary. After an account has been created on this website, there is a bulletin board is available for you to advertise AECs that you have been issued, however all transactions will be conducted through the PJM-GATS website. This website will help you facilitate the sale of AECs to electric suppliers who are required to purchase of clean energy AECs under the Pennsylvania AEPS program.

Please note that aggregators need to submit an application for each facility they represent. All facilities will receive an individual certification number.
