Hockey Stick: U.S. Residential Energy Storage Deployments Q1 2018
June 7th, 2018Via: GTM:
Ever since GTM Research began tracking storage deployments in 2013, residential batteries appeared as the faintest of slivers on the industrywide bar graph, nonzero but totally insubstantial.
Now, for the first time, the smattering of a few kilowatts here and there has nearly overtaken the giants of grid-scale mega-projects. That’s a result both of the mega-projects not showing up this quarter and the micro-projects swarming into action.
Dialing into the numbers, it’s clear that California and Hawaii drove this newfound strength with state-level growth that merits no less than the technical designation: “bonkers.”
California’s resi sector rose 3,833 percent year-over-year in terms of megawatts, 4,324 percent in terms of megawatt-hours. The fact that energy capacity grew more reflects that these systems are sizing up to hold more duration.
