Are you Capacity Market Auction ready?

14 Jan 2021

It’s that time of year again where attentions turn to the capacity market, with a flurry of activities over the coming months leading up to the T-1 & T-4 auctions held on 2nd and 9th March 2021, respectively.

The Capacity Market was introduced by The Depart​ment of Business, Energy and Industrial Strategy as part of the Electricity Market Reform programme to ensure the future security of our electricity supply.

Prequalification closed in September 2020, with a total of 4.4 GW (de-rated capacity) of projects prequalifying, or conditionally pre-qualifying, for the 2021-22 (T-1) auction and 53 GW for the 2024-25 (T-4) auction.

The charts below show the range of prequalified technologies for each auction. Coal operators will be looking to ‘sweat their assets’ in the T-1 auction ahead of the UK coal phase out by 2025. Whilst gas continues to account for a substantial percentage of the mix. Offshore wind has not made the list, as had been anticipated, with onshore wind and solar only accounting for a very small percentage of the mix. Overall, the prequalification list reflects the diversity in the UK’s energy mix with a move away from fossil fuels and increase in low carbon technologies.
