Renewable energy facilities create electricity that is delivered to a network of transmission wires, often referred to as the grid. Renewable energy generation produces two products: 1) the electricity or electrical energy produced by a renewable generator and 2) the renewable attributes of that generation. The renewable attributes or green attributes are sold separately as energy certificates, or RECs. A REC can be created only if the renewable electricity was produced, and only one certificate may be issued for reach unit of renewable energy produced. If the electricity was separated from the REC and sold without the REC, that electricity is no longer considered renewable and cannot be counted as renewable or zero-emissions by whomever buys it. Note that PCE does not purchase “unbundled” RECs to supply our products. Instead, PCE purchases renewable energy along with the associated RECs from that facility.
