The Poland arm of UK-based developer Harmony Energy is looking to bid in around 500MW of battery storage projects into the upcoming capacity market auction, executive director Michał Maćkowiak said.

Europe’s biggest battery storage system earned £2.3 million (US$2.85 million) revenues in Q1 2023.

Battery storage projects totalling 627MW were awarded contracts in the UK’s 2023-24 Capacity Market auction which concluded yesterday (14 February), nearly a two-thirds jump on last year’s.

UK clean energy developer Harmony Energy has brought online a 98MW/196MWh battery energy storage system (BESS) project.

Fotowatio Renewable Ventures (FRV) and UK developer Harmony Energy have begun construction of their 198MWh Tesla battery project in England.

Harmony Energy has secured a £60 million debt facility from major UK retail and commercial banking group NatWest.

The Capacity Market T-1 auction cleared at a record high price in the UK this week, with 17 batteries winning spots.

In an effort to make it easier for smaller participants to bid into the Balancing Mechanism (BM), National Grid ESO has introduced a new interface.
