LONDON (Reuters) – Britain’s auction to ensure enough electricity capacity for 2022/23 cleared at a record high of 75 pounds per kilowatt (kW) per year on Tuesday evening, National Grid said. A total of nearly 5 gigawatts of capacity was procured, National Grid said. Britain launched its power capacity market in 2014, offering to pay providers for making supplies available at short notice. (Reporting by Nina Chestney; Editing by David Goodman)
