    The following flow diagram categorises the Capacity Market into five stages. The first stage 'Capacity' represents the determination of the Capacity to be procured. This stage is followed by 'Prequalification', which covers the procedure through which interested parties qualify for participation in the 'Auction'. Applicants who are successful in the Auction receive 'Agreements' outlining their Ca​pacity obligation. Depending on Applicant type, certain obligations have to be fulfilled prior to and beyond the start of the Delivery Year. Once the Delivery Year commences, the agreements enter the final stage i.e. 'Delivery'. During the Delivery, the agreement holders need to be available for delivering their Capacity Obligation to receive Capacity Payments.​
