Nomination is the process of accepting orders for gas where more than one buyer or partner have claim to a shared resource of gas. An agreement between the partners determines how the gas can be nominated. The PSACS system implements these agreements into a trading system to handle nominations as they are processed by the operator. To introduce the main elements of PSACS a typical day using PSACS is reviewed below.
