UK energy company Harmony Energy said its £75m ($90 million) Pillswood battery energy storage system (BESS) in East Yorkshire has officially opened.
Peter Kavanagh, Harmony Energy Limited’s CEO, said the 98MW/196 MWh scheme – Europe’s largest by MWh – was completed well ahead of schedule.
The site is next to National Grid’s Creyke Beck substation. That connection point is proposed for phases A and B of the world’s largest offshore wind farm, Dogger Bank. The first phase is set to go live this summer, said Harmony.
It will provide balancing services to the GB electricity grid network.
Kavanagh said Pillswood is Harmony’s third, and largest, BESS. It employs a Tesla 2-hour Megapack system with lithium iron phosphate batteries.
He told BEST it is the first of six similar projects the Trust intends to deliver in the coming year. They will all use the Tesla Megapacks.
