Aggregating connected energy storage systems to create ‘virtual power plants’ is likely to become a big part of the next phase of storage, according to the executive director of the US-based Energy Storage Association.

While debates over renewable energy targets continue to rage at the political level in Australia, Panasonic has signed a deal with three utility companies to pair its energy storage systems with rooftop solar.

Battery and storage system maker A123 will double its production output to 1.5GW through a capital expansion plan worth more than US$300 million, the initial phase of which the company says has already begun.

Electric vehicle manufacturer Tesla and renewable energy developer Gaelectric have announced a joint test project to evaluate utility-scale storage to facilitate the integration of renewables onto the grid.

Lessons learned from solar could help develop financing solutions for energy storage that could be “key” to unlocking the potential of the technology, strongly benefiting PV in the process, Jigar Shah has said.

To hit the best possible cost reduction outcomes, lithium-ion battery producers will have to scale-up to go beyond 1GWh of production capacity, but will hit a ceiling when they reach 10GWh, a new report claims.

SunEdison co-founder Jigar Shah will deliver a keynote address at next week’s Energy Storage Association annual conference and exhibition in Texas. Other organisations and companies speaking at the event represent a bona fide “who’s who” of the US energy storage market landscape.

Trojan Battery, manufacturer of deep-cycle lead acid batteries, has announced that it is expanding its research and development capabilities with a new facility in Sligo, Ireland.

Energy storage solution provider Eos Energy Storage has announced that it has raised US$23 million in Round C equality financing — which it will use to help its commercial launch of the company’s grid-scale battery technology.

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.
