Siemens’ international financing arm, US development bank NADBank and energy storage developer EnerSmart Storage have signed a US$78.2 million loan facility to finance a fully merchant battery storage project in California totalling 165MW.

The opportunities for energy storage in the US continue to grow and grow, but moving away from contracted revenue structures to merchant risk projects will be a challenge, especially for lenders. 

Paris-headquartered renewable energy power producer Voltalia has begun construction of a 32MW / 32MWh battery energy storage system (BESS) project in the UK.

Battery system integrators must navigate a broad array of technologies and varying market drivers when putting systems together. Andy Colthorpe speaks to Powin Energy and Sungrow about the engineering challenges involved in building lithium-ion battery storage.

With a quarter of all solar project proposals in the US including batteries, transmission grid operators across the country are taking a variety of steps to evaluate the role that can be played in wholesale electricity markets by hybrid power plants – defined as generation coupled with energy storage.

Developer NRStor and technology provider Hydrostor have completed work on a multi-megawatt, commercial, advanced compressed air energy storage (A-CAES) system in Canada.

Electricity and heat generator and retailer Vattenfall is developing a third party model for energy storage deployment, which will see the Swedish firm deploy batteries alongside UK solar farms.
