The auction parameters letter sets out the target volume to be secured through the T-4 Capacity Auction for 2020/21, the early auction for 2017/18 and the DSR transitional arrangements auction, also for 2017/18. It also includes the de-rating factors for interconnectors. The final auction targets are based on the advice provided National Grid in the Electricity Capacity Report, which has been scrutinised by the panel of technical experts.
Today we are confirming that we will seek to secure:
53.8GW in the early auction for delivery in 2017/18
300MW of turn-down DSR in the transitional arrangements auction for delivery in 2017/18
52GW in the T-4 auction for delivery in 2020/21 (with an additional 600MW in the associated T-1 auction)
The T4 target is some 6GW higher than in last year’s equivalent auction, in line with the Government’s announced intention to buy more capacity and buy it earlier.
