With energy storage deployments in the US up almost 50% year-on-year, according to GTM Research analysis, the next big question for the industry might be who gets to own all of the assets.

As might be expected, California’s main utilities led the way in 2016 for US state-by-state deployment of energy storage, with Southern California Edison installing as much as 40% of the national total, according to a new survey.

An analyst at Navigant Research has said he was surprised to see Tesla dominate California’s SGIP (Self-Generation Incentive Program) applications, with the Silicon Valley car and tech company accounting for half of all requested funds.

The US state of California’s Senate has approved a bill that would provide rebates to customers for the purchase of energy storage systems, bringing the legislation a step closer to introduction.

California’s Self-Generation Incentive Program (SGIP), the scheme to incentivise the use of distributed energy, opens for applications at the beginning of next month, weighted to favour energy storage.
