The Capacity Market - CM

If you have a generation asset or can reduce your demand within a four-hour notice period, then you may be able to participate in the Capacity Market. Under this scheme, participants are paid an availability payment for being connected.  

There are strict rules to prequalify and meet the various milestones required to participate in the Capacity Market. These are designed to protect the requirements set for this market and ensures the delivery of the contracted amounts. We have a proven track record in managing and qualifying in this process.

Historical prices have varied significantly in line with market supply and demand. New build generators can apply for a 15-year contract in the T-4 auction whilst existing generators or those able to reduce demand can apply for a one year contract in the T-1 auction. The price paid is determined by an annual auction hosted by National Grid.
