National grid turns to batteries
Between June and August 2020, the National Grid Electricity System Operator’s (ESO) reliance on battery storage to balance the grid rose by 150 per cent.
The figures, shared in a new report form Cornwall Insight, also show that the use of gas reciprocating engines increased by 338 per cent, the use of aggregated units increased by 518 per cent, and the use of wind energy increased by 125 per cent, compared to 2019.
Lee Drummee, analyst at Cornwall Insight, said to Electrical Review, “what is most interesting is the technologies that have been providing these balancing actions to the ESO.
“Newer asset types such as batteries, gas reciprocating engines and aggregated units, which are formed up of multiple technology types, have seen the greatest percentage increase in activity.”
