Forward Capacity Auctions (FCAs) are held annually approximately three years before the capacity resources must provide service. That delivery period is called the capacity commitment period (CCP). Capacity resources compete in the annual FCA to obtain a commitment to supply capacity in three years. This commitment is called a capacity supply obligation (CSO). Suppliers with the lowest-priced offers clear the auction and receive capacity payments based on the auction clearing price. These payments are in addition to what resources receive in the energy and reserve markets. In exchange for capacity payments, the resources have an obligation to be ready to run when called on.
