UK battery storage investor Harmony Energy Income Trust (HEIT) has energised two grid-scale battery energy storage system (BESS) assets, including one of the same size as its flagship ‘largest BESS project in Europe’.

The company announced today that it has energised Bumpers, a 99MW/198MWh asset in Surrey, England, as well as the 49.5MW/99MWh Little Raith project in Fife, Scotland. The pair went online and into operation earlier this month, HEIT said.

The output of Bumpers is 1MW larger than the investor’s Pillswood project, and has the same capacity in megawatt-hours. Pillswood was brought online in November 2022 and is currently thought to be the largest standalone battery storage system in Europe.

It was also winner of Standalone Grid-Scale Project of the Year in the Energy Storage Awards hosted by our publisher Solar Media a few weeks ago, and was the subject of a case study article for our quarterly journal PV Tech Power earlier this year, written by Alex Thornton, operations manager at HEIT’s parent company Harmony Energy.

Developer Harmony Energy, which now has around a gigawatt-hour of BESS projects in operation in the Great Britain (GB) market as well as a pipeline of a few hundred megawatt-hours in development or construction, launched HEIT in 2019 to raise funding for its battery projects.
