E.ON Climate & Renewables North America is to build a 10MW battery energy storage facility with a 2MW solar array in collaboration with Arizonan utility Tucson Electric Power (TEP).

German solar integration specialist Belectric has begun serial production of its ‘Energy Buffer Unit’ (EBU) battery system.

Energy storage is to be included in India’s state-run solar energy tenders for the first time under plans to help smoother integration of renewables into the grid.

The UK’s Institution of Civil Engineers (ICE) has publishing a report which looks at how unlocking the potential of electricity storage through regulatory changes would support the transition to a secure and affordable low carbon economy, adding to a chorus of recent voices on similar topics coming from Britain.

Highview Power Storage, a UK company which makes energy storage systems based on liquid air technology, has said that work is well underway on a 5MW demonstration project in the north-west of England.
