How do AECs Differ from RECs and Green Tags?
AECs are no different from Renewable Energy Credits (RECs) and Green Tags. “Green Tags” is a generic term for electricity generated from a variety of renewable energy sources including solar, wind, small hydro and biomass. The PA AEPS Program chose to call their credits Alternative Energy Credits (AECs) which include both renewable energy resources and other Pennsylvania-specific alternative resources. RECs and Green Tags are widely used to meet various state renewable portfolio standards and are traded in both compliance and voluntary programs in wholesale and retail markets across the U.S.
