UK gas and electricity market regulator Ofgem has made a “game changer” decision for UK energy storage, by confirming that solar farms are able to retain accreditation under the government Renewables Obligation (RO) when supplying electricity to batteries.

Developer Anesco has continued to rack up utility-scale storage work after agreeing to retrofit 10 of Ancala Partner’s PV arrays in the UK with battery units.

Trina Best, the energy storage company begun as part of Trina Solar but now a separate entity in its own right, wants to go public by 2020 and has not ruled out building its own battery cell production facilities in future.
