A wind farm with co-located battery storage, in development by UK-headquartered multinational renewables developer and EPC provider RES Group, is to go ahead in Australia.

Scotland’s first utility-scale battery storage facility has been officially opened today, having begun delivering sub-second balancing services to National Grid at the end of June under a bespoke agreement secured before the hotly contested Enhanced Frequency Response (EFR) auction of 2016.

Applications made to the government of New South Wales in Australia for two solar farms totalling 285MW of capacity are open to comment from stakeholders and members of the public.

British investment trust, The Renewables Infrastructure Group (TRIG), has become the latest investor to enter the large scale energy storage market after buying a 20MW project from RES for £20 million (US$25.9 million).

UK-based infrastructure investor Foresight Group has sealed its maiden battery storage purchase, acquiring the 35MW RES-built Port of Tyne project in the North-East of England.

A 1MW/1MWh energy storage system from system integrator Renewable Energy Systems (RES) has been selected for testing by the US Energy Department.

Renewable Energy Systems ranks alongside US firm AES at the top of a new leader-board of energy storage systems integrators; its two new National Grid contracts will see it top the table, it says.
