Energy aggregators Flexitricity and Limejump were recently called on to balance the National Grid after the UK-French interconnector failed, prompting output to halve and 1 GW to fall off the system. A graph illustrating the interconnector's trip and the subsequent drop in capacity. Limejump said its battery frequency response assets were the first to kick into action, and added there was "minimal" impact on pricing within the balancing mechanism. The UK is also looking at a new generation of energy storage technology that could be used in combination with existing power stations or pumped hydro storage.
