Question:
To ask the Secretary of State for Business, Energy and Industrial Strategy, what progress has been made on developing large-scale electricity storage solutions.
Answer:
Kwasi Kwarteng:
As of 2018 there was around four gigawatts of storage on the system in Great Britain, and three gigawatts of this was from pumped hydro (National Grid Future Energy Scenarios, 2019).
Government is investing to support further development of large-scale electricity storage solutions. In January this year Government launched the ‘Storage-at-Scale’ competition which commits up to £20 million to support the development of innovative, replicable solutions that could provide an alternative to conventional commercial large-scale energy storage technologies.
