It has been the US’ busiest quarter to date for behind-the-meter energy storage installations, driven in part by residential adoption in the advanced markets of California and Hawaii, GTM Research has found.

According to the latest GTM Research figures, energy storage is coming into its own and is no longer confined to a handful of US states. 21 states now have 20MW of storage projects proposed, in construction or deployed. Further, 10 states have pipelines of more than 100MW.

Software for energy storage systems will be a mixture of in-house solutions by integrator/ developers and third-party providers, in an industry segment set for a steep rise in value, according to one expert.
