US to install 1,233 MWh of energy storage capacity in 2018, says report

CTBR Staff Writer Published 08 March 2018

The US is expected to install 1,233MWh of grid-connected energy storage in 2018, which is almost double than what it has been for the last five years, as per a report from GTM Research and the Energy Storage Association (ESA).

The fourth quarter of 2017 saw 100MWh of energy storage deployed in the US, taking the total of energy storage between 2013 and 2018 to 1,080MWh, revealed the U.S. Energy Storage Monitor 2017 Year-in-Review.

In 2017, there was a 27% growth in the US energy storage market with installation of 431MWh.

GTM Research energy storage director Ravi Manghani said: “We’re going to have to strike the word ‘nascent’ from our vocabularies when describing the U.S. energy storage market.

“Falling costs and favorable policies will be among the core drivers of the market’s breakout 2018. It's not hard to imagine that every solar RFP by the end of the year will include storage.” ?

The report said that most the deployments were made up by the front-of-meter market. However, there was a significant growth of 79% year-over-year for the behind-the-meter market which saw record deployments across residential and non-residential segments.

Among the states, California topped the list for most deployments in the behind-the-meter market. This was largely due to the Self-Generation Incentive Program, according to the report.

Apart from California, other markets like Hawaii, Massachusetts and New York had experienced strong growth.

As far as the front-of-meter market is concerned, there was a growth by 19% quarter-over-quarter, due to longer-duration systems in North Carolina, reveals the report.

It noted that although a number of important projects slipped from the fourth quarter of 2017 into 2018, the front-of-meter segment still had a positive growth of 10% annually in megawatt-hour terms on the year.

The report also forecasts the annual value of the US energy storage market to cross $1.2bn in 2019.
