US energy storage deployments for the first time saw home energy storage beating out front-of-meter storage figures in the second quarter according to Wood Mackenzie Power & Renewables’ most recent US Energy Storage Monitor.
Wood Mackenzie Power & Renewables (formerly known as GTM Research) this week published its most recent US Energy Storage Monitor in collaboration with the Energy Storage Association, revealing that 156.5 megawatt-hours (MWh) of energy storage were deployed in the second quarter of 2018, 24% over the MWh installed in the first quarter of 2018 but a phenomenal 200% over that which was deployed a year earlier (though it’s worth noting that Q2’17 was particularly low).
In terms of MW installed, the second quarter saw 61.8 MW installed compared to 43.6 MW installed in the first quarter of 2018 and up 60% year-over-year.
The top energy storage markets across the United States depend on the sector in question, with California leading the residential and non-residential sectors, but Arizona driving front-of-meter deployments.
Residential deployments for the quarter were concentrated in California and Hawaii, which together accounted for 72% of all MWh deployed in the quarter. Brett Simon, a Wood Mackenzie Power & Renewables senior analyst, believes that there are no signs that either state will yield their grasp on the top two spots for residential solar installation — though there is a race for the number three spot, with both Massachusetts and Arizona making ground.
“So far in 2018, 24 states and the District of Columbia have taken some form of regulatory or legislative policy action with respect to energy storage, with even more states poised to do so in 2019,” said Kelly Speakes-Backman, CEO of the Energy Storage Association. “The industry is bullish about continued state action designed to ensure fair and equal access for storage to the grid and markets, to enable competition in all grid planning and procurements, and to capture the full value of energy storage. As these barriers to storage are removed in state markets, we will likely see new state names on the leaderboards for residential, non-residential, and front-of-the-meter deployments.”
