Green energy gets switched off as power systems fail to keep up

Wind and solar generators stop production at rising rates as grids and battery storage lags

Wind and solar farms are wasting energy at rising rates by stopping production because there is not enough capacity to transport or store the electricity when demand is not high enough to use it straight away. 

Almost one-tenth of Britain’s planned wind output was stopped from being produced last year and almost 30 per cent of Northern Ireland’s, according to analysis shared with the Financial Times by Aurora Energy Research.
