National Grid ESO is set to debut a new fast frequency response service at 11pm tonight (1 October), using Dynamic Containment (DC) to boost the grid’s resilience. Following an extensive consultation period, six tenders were received for the ESO’s new sub-second, post-fault response capability, from which two battery energy storage units were accepted in the first round. These will provide 90MW of fast response services over 24 hours, with 165MW from six units available to compete in the day ahead tender for 2 October. The ESO will now run tenders for DC seven days a week, procuring from 11pm to 11pm, in a move that will help to bring the frequency response market closer to real-time. This will give it an arrangement similar to one of National Grid ESO’s current frequency response auction trials, the operator said.
