UK renewables and battery developer Anesco has warned that the looming de-rating of battery storage in the Capacity Market risks scaring investors away from the technology.

Anesco is investigating how it could adopt flow batteries into future projects instead of lithium as a response to growing uncertainty around the future of storage de-rating in the capacity market, Clean Energy News can reveal.

UK-based renewables developer Anesco says the inclusion of battery storage has been central to the economic viability of the country’s first subsidy-free solar farm, a 10MW site the company has just unveiled in the east of England.

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.

Green Hedge, a UK renewable energy developer that has diversified into battery energy storage systems, has had an application for a 40MW project approved by local authorities in Derbyshire, England.

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.

Energy efficiency solutions provider and energy storage developer Anesco is to partner with “technology-driven utility” Limejump to deliver 185MW of energy storage capability in the UK into August’s capacity market, with plans for the units to be brought online by the end of 2018.

UK energy efficiency solutions provider Anesco has bolstered its portfolio of operational storage solutions, installing its second commercial battery at a solar farm.
