The Wholesale Market is the primary market for wholesale electricity trading between generators and suppliers. Electricity can be traded from years ahead up to one hour ahead of the delivery. Flexible technologies such as batteries and gas reciprocating engines are mainly targeting short-term trading by providing real-time flexibility to help balance the system. Therefore, they trade mainly in day-ahead to intraday markets.

• Day ahead hourly, half-hourly and intraday auctions

• Within day power markets on the intraday exchange

Two auctions are held yearly to disburse capacity contracts 1 and 4 years ahead of delivery for keeping generation capacity ready for response.

Providers are paid an availability payment for being connected. New build generators can apply for a 15-year contract in the T-4 auction while existing generators or those able to reduce demand can apply for a one-year contract in the T-1 auction. To ensure delivery, there are stringent rules to prequalify and meet the various milestones required to participate in the Capacity Market. 

All of Statera’s assets are designed to deliver this reserve service to National Grid.

This is to respond to events including power station trips, demand surges and intermittent renewable generation. Flexible technologies such as batteries and gas reciprocating engines are well placed to provide real-time flexibility in the BM to help.
