September 13 (Renewables Now) - UK-based battery energy storage asset owner and operator Varco Energy has selected Fluence Energy UK Ltd to deliver a 57-MW/137.5-MWh battery energy storage system (BESS) in England.
The planned facility, named Sizing John, will be located the Rainhill substation, south of the Merseyside town of St Helens.
Varco said that the BESS will assist the National Grid Energy System Operator (NGESO) in grid balancing as more renewables get added. It will also trade in wholesale power markets by shifting excess renewable energy into periods of peak demand, and support energy security via participation in the capacity market.
Sizing John is designed for future expansion to match higher connection capacity expected in 2026, aiding NGESO in addressing grid congestion, Varco added.
"Sizing John is our first project in the British market with a duration of 2.4h, as we are committed to providing tailor-made solutions and applications our customers and markets need," commented Brian Perusse, Managing Director of Fluence Energy UK Ltd.
Varco, a vehicle backed by the Adaptogen Capital Battery Storage Fund, currently has 114 MW of BESS projects under construction in the UK.
Fluence Energy UK Ltd is a subsidiary of Fluence Energy Inc (NASDAQ:FLNC), the energy storage specialist jointly owned by Siemens AG (ETR:SIE) and AES Corp (NYSE:AES).
