Energy minister Anne-Marie Trevelyan has written to National Grid Electricity System Operator to accept its recommendation to raise the target volume for the upcoming year-ahead (T-1) Capacity Market auction to 2.4GW. The new figure represents a more than six-fold increase on the previous target of 400MW and primarily reflects a significant reduction in the amount of the generation that is expected to be available due to outages, delays or cancellations to new plants and the decommissioning of existing capacity.
