Energy companies Flexitricity and Limejump were recently called on to balance the National Grid after the UK - French interconnector collapsed , prompting output to halve and 1 GW to fall off the system . However Limejump assets were called by the control room at better prices than they would have received if there was no event. Limejump said its high frequency response assets were the first to kick into action , and added there was " minimal " impact on pricing within the balancing mechanism . The collapse happened during a coal - free fortnight for the UK , as an uptick in wind generation caused " significant " drops in energy prices .
