(asked on 20th February 2018) - View Source
Question to the Department for Business, Energy and Industrial Strategy:
To ask Her Majesty's Government how many gigawatts of large scale long duration electricity storage, of over four hours, was on the National Grid last year; and what assessment they have made of the total requirement for this year.
This question was answered on 2nd March 2018
Long duration storage, in the form of pumped hydro, accounted for just under 3GW capacity in GB last year. National Grid, as System Operator, takes a technology neutral approach to securing services that meet the needs of balancing the electricity system, and is in the process of setting out future needs through their System Needs and Product Strategy.
