2018 Utility Energy Storage Market Snapshot

According to US utilities, 2017 storage reports got it wrong.

Want to know what actually happened in the energy storage market last year? We made it easy and did the hard work for you. Our utilities say that GTM Research and other industry sources undercounted the amount of grid-connected storage and behind-the-meter storage deployed in 2017.

The Utility Market Snapshot Series delivers what no other industry reports can: unbiased analysis and figures based on verified interconnection data from over 130 US utilities. No data modeling. No guesswork.  Just hard facts from one of largest utility surveys in the industry, now called the Utility Transformation Survey. In this year’s Utility Energy Storage Market Snapshot, you will learn about the expanding applications of energy storage and key market trends. Some key data points include:

• An emerging, booming market: The market saw 104% growth of deployed MWh from 2016. In 2017, U.S. utilities interconnected 217 megawatts (MW), 523 MWh of energy storage across a total of 2,588 systems.
• Utility-supply dominates growth: Residential deployments accounted for 13 MW, 29 MWh; while non-residential added 59 MW, 140 MWh, and utility supply accounted for the largest share at 144 MW, 355 MWh.
• State-level policy pilots: Details on five state policies to grow local storage markets.

What’s in the report

This year’s snapshot delivers critical data and findings such as:

• U.S. energy storage rankings by utility in MW, MWh, watts per customer account, and watt-hours per customer account
