Changes to the de-rating factors for battery storage projects competing in the UK’s Capacity Market (CM) will push the sector towards longer-duration batteries, while potentially sparking a shift towards energy arbitrage as a source of revenue for shorter duration applications. David Pratt heard from several industry sources following last week’s announcement.

The tiny Caribbean island of Saba, a Dutch municipality apparently filmed in silhouette for the 1933 film adaptation of King Kong, is tendering for a utility-scale solar park coupled with battery energy storage.

We often hear about California’s leading position in solar and latterly in energy storage. Perhaps lesser known than direct policy support for energy storage and renewable technologies is the way California’s network operator (CAISO) is starting to reconfigure how it procures demand response, with a positive impact for energy storage – and particularly behind-the-meter assets, as Ted Ko, policy director of Stem, explains.
