UK investment company Harmony Energy Income Trust said it energised its 99MW/198MWh Bumpers battery energy storage system (BESS) in Buckinghamshire, England. It claimed it is the joint largest BESS by MWh in Europe.
The technology is based on Tesla’s Megapack 2XL system, operated through Alfabidder, a trading platform based on Tesla’s algorithms. Each single lithium-ion battery unit has a storage capacity of 3.9MWh.
Scalability is available up to more than 1GWh. The inverter size at 480V AC is up to 1583kVA for a two-hour system. Output is between 380 and 505V for the 3-phase system.
The project will contribute to grid balancing of the national network thanks to its capacity to store surplus of power when renewable generation exceeds demand. The system offers seamless SCADA integration.
Harmony Energy now owns two of the three largest BESS sites in Europe. The company said it controls an operational capacity of 277.5MW/555MWh. Energy group BP announced in September that it will provide physical power trading and optimisation services for two of Harmony’s BESS from the first half of 2024.
Max Slade, Harmony director, said: “We want to be at the forefront of a greener and more sustainable future, and the energisation of the new projects is another significant step in the right direction for achieving net zero and our full portfolio build-out.”
The company said it has another three projects due to complete construction within the next six months at Rusholme, Wormald Green and Hawthorn Pit.
