RES will develop a battery system to supply up to 20MW to the grid in less than a second of the detection of frequency deviation.
The renewable energy firm said the system will be in place by the end of 2017.
Six similar projects have already been installed in North America, according to RES.
"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 US.
"Now, developing this innovative service with National Grid is a major step in the development of our UK energy storage business," said RES energy storage manager John Prendergast.
National Grid senior account manager Adam Sims said it would be the first time battery storage has been used to provide "fast-acting" response service to the UK grid.
