Anesco plans to build 300MW of battery storage in next two years

Anesco says it will build out around 300MW of new battery storage projects by 2020, taking its portfolio to 380MW.

The Reading-based firm currently has 87MW of battery storage in operation across 27 sites and has several projects under construction, including a 50MW project in Hampshire.

Many firms and financiers are struggling to make battery storage economics stack-up, given high costs and uncertainties over bankable revenue streams. However, Anesco executive chairman Steve Shine said the data from its operational facilities, stretching back to 2014, was a “crucial differentiator”.

This has enabled us to … predict whole life cost, IRR and long term revenue streams – the numbers that really count,” said Shine. “Our batteries are performing above specification and are delivering a strong economic return for our customers,” he claimed.

Last year Anesco developed the UK’s first subsidy-free solar scheme (Clayhill, pictured) by combining it with batteries at a site with a good existing export connection.
