National Grid and RES have signed a four-year contract to develop the first battery energy storage systems to provide a dynamic frequency response in sub-second timescales in the UK.
RES aims to provide 20MW of frequency response from battery storage, which will aid National Grid in performing system balancing.
The partners said the battery storage systems will be fully operational within 18 months.
RES has already commissioned six similar projects in North America.
National Grid senior account manager Adam Sims said: “This is the first time that battery storage will be used to provide such fast-acting frequency response service to the national transmission network in Great Britain.
“This technology will enable us to respond to frequency issues in under a second, helping to maintain the integrity of the grid.”
RES energy storage manager John Prendergast said: “RES has previously pioneered the delivery of very fast frequency services in Canada and is one of the largest providers of such services in the USA.
“Now, developing this innovative service with National Grid is a major step in the development of RES’ UK energy storage business.”
