Nidec ASI has been selected as supplier of batteries to a 49MW energy storage project in the UK by EDF, which will help balance the grid and generate revenues until at least 2035.

Developers who were successful in winning contracts within last week’s Capacity Market auction have lauded the “crucial role” battery storage is set to play in the future for the national grid.

Moves by the US’ Federal Energy Regulatory Commission (FERC) to assess electricity storage’s potential role in wholesale markets and in maintaining a low-cost, reliable network have been welcomed by the Washington-headquartered Energy Storage Association.
