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).

The signing of a contract to deploy batteries for dynamic frequency response in Britain is an indication that grid operators and the renewables industry can work together to benefit energy users, developer RES has said.

Battery energy storage used on the grid for ancillary services has been gaining momentum ever since the United States changed its frequency regulation markets by introducing a concept known as pay-for-performance. Roger Lin of NEC ES takes a good look at how this space is evolving, as the UK’s National Grid prepares a 200MW tender for enhance frequency response.

Europe’s largest energy storage battery project could conceivably also be its best looking, as these pictures show. The two companies behind the project, which saw a large-scale energy storage system deployed in the small German village of Feldheim, also decided to call on professional street artists and invited schoolchildren to get involved with designing the outside of the system’s enclosure.

News in brief: Germany’s tiny renewable energy village gets biggest battery; Tesla-backers invest in Kazakh-bound Primus Power and industry partners match US$2 million grant for California distributed resources trial.

Tom Tipple, regional VP for Imergy Power Systems, a flow battery maker headquartered in Fremont, California, recently visited the PV Tech Storage offices to share his thoughts on the global market for energy storage.

A small number of regional markets are leading the way for energy storage deployment in the US, but this is likely to change in the near future, an analyst from GTM Research has said.

Invenergy has brought a 31.5MW energy storage facility online to provide frequency regulation for the grid, near to 230MW of renewable energy generation assets.

A large-scale storage system co-located at a German solar farm by the PV plant’s developer Belectric, has been given the green light to operate in the grid-balancing frequency response market.
