Feb 21 (Reuters) - Britain's auction to ensure enough electricity capacity for 2026/27 has cleared at 63 pounds per kilowatt (kW) per year, National Grid said on Tuesday.
A total quantity of 43 gigawatts (GW) of capacity was procured, a provisional auction document showed.
Britain launched its power capacity market in 2014, offering to pay providers for making supplies available at short notice.
The clearing price is reached when the total offered capacity is equal to that demanded.
Auctions are usually held about four years in advance of the delivery date, with another auction for a smaller amount of capacity held a year before delivery.
Out of the total 43 GW procured, 29 GW was from gas-fired power plants, 6.9 GW from power imports and about 3.1 GW from battery and pumped storage, with the rest from other sources, the document showed.
About 87.4% of the capacity procured in the auction was from existing power assets and interconnectors, the auction results showed.
The companies that bought contracts in the auction included RWE, SSE, Uniper and EP UK.
RWE secured contracts comprising capacity of 6.6 GW while both SSE and Uniper landed contracts for 4.3 GW each and EP UK for about 4 GW.
National Grid's interconnectors with neighbouring countries also procured contracts for about 5.4 GW of capacity. (Reporting by Brijesh Patel and Deep Vakil in Bengaluru; Editing by David Goodman, Mark Potter and Andrea Ricci)
