Various firms in Pennsylvania and across the United States specialize in aggregating Alternative Energy Credits (AECs) or serve as brokers between certified alternative energy generators and Pennsylvania’s electricity distribution companies (EDCs) or electricity generation suppliers (EGSs).

For an aggregator or broker to be authorized to buy or trade AECs, the firm must provide PennAEPS with documentation that an alternative energy generator authorized the transfer of ownership of the generator’s AECs.

The price of an AEC is negotiated between alternative energy generators and the broker or aggregator of their choice. The PUC tracks historical AEC pricing.

AECs can be traded until they expire or are retired for compliance purposes, and no single AEC can be jointly claimed by multiple parties.. AECs are eligible for use in the PA AEPS Program in the energy year in which they are generated, and for the following two energy years. The energy year runs from June 1 to May 31. For example, an AEC generated in August 2020 will be eligible for compliance purposes during energy years, 2021 (credits generated from June 2020 to May 2021), 2022 (credits generated from June 2021 to May 2022) and 2023 (credits generated from (June 2022 to May 2023).

The following firms have requested to be listed as an aggregator and/or broker to buy or trade Pennsylvania AECs. You can also find information about brokers and aggregators on the PJM-GATS website.
