Less capacity should be sought in the forthcoming Capacity Market auctions, according to National Grid.

In its newly-released Capacity Market Auction Guidelines, the system operator has recommended cutting the targets.

National Grid recommends targeting 4.9GW of capacity for the T-1 auction covering the winter of 2018-19, down by 1.1GW.

It also suggests cutting the target for the T-4 Capacity Market auction in 2021-22 by 600MW to 49.5GW.

Auctions due in coming weeks

It said the changes were in light of latest insight into factors included the level of underlying peak demand during cold spells.

The T-1 auction is due to take place on 30 January, while the T-4 auction is scheduled for 6 February.

National Grid’s recommendations will need to be approved by the Energy Secretary.

Last month, the system operator revealed that bidders offering a total of 15.5GW had prequalified for the T-1 auction, while those offering 91GW had prequalified or conditionally prequalified for the T-4 auction.
