We look at which BESS suppliers have supplied which UK project owner-operators, with data from our Market Research colleagues.

Sungrow has signed a 2.4GWh strategic deployment agreement for battery storage systems in Europe with solar PV solutions provider SUNOTEC.

Utility and power generation firm EnBW has presented a 400MW/800MW BESS project proposal to a municipal council in Germany, for deployment at its Philippsburg nuclear power plant which is in the process of being decommissioned.
