Earlier this year, Western Power Distribution, a DNO, signed a contract with RES (a renewable energy company) to deliver an energy storage system co-located with a 1.5MW solar farm. This project aims to demonstrate the network services "solar + storage" can provide behind-the-meter to the owner and operator of the solar farm and to DNOs.
