The US energy storage market deployed 40.7 MW worth of storage in the second quarter this year, its best quarter in two and a half years, says GTM Research.

GTM Research and the US Energy Storage Association released the latest edition of their US Energy Storage Monitor report, which highlighted the country’s impressive second quarter energy storage market growth. Specifically, the second quarter saw the interconnection of a 31.5 MW solar project in the PJM region — a regional transmission organisation that coordinates the movement of wholesale electricity in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the District of Columbia.

This quarter is the largest quarter, and this project is the single largest solo project to come on line, since the fourth quarter of 2012, when the Notrees 36 MW project was interconnected in Texas.


Behind the meter, in the non-residential energy storage market, had its best quarter ever, deploying 4.9 MW of storage, with a big share of that growth coming from California, where GTM highlights “the massive pipeline of [Self-Generation Incentive Program] SGIP-approved projects finally began to be interconnected.

“It is promising to see that outside of PJM and California, 10 states had significant activity related to energy storage policies and programs in the last three months,” explained Ravi Manghani, GTM Research Senior Energy Storage Analyst and lead author of the report. “This is a good sign for the industry, which has leaned on a handful of markets for its growth to date. We have states like Minnesota and Washington that are looking to grow their storage industries, while others like Massachusetts and New Jersey are using storage to modernize the grid and make it more resilient.”

The authors of the report note that PJM and California will continue to be the regional energy storage market leaders for the foreseeable future.

“The number of different states that are actively engaging in energy storage shows that regulators, legislators and utilities are seeking innovative ways to deploy systems,” said Matt Roberts, Executive Director of the Energy Storage Association. “Advanced storage systems are being leveraged to increase reliability and resiliency in the Northeast, offset the need for ‘peaker plants’ in the Southwest, and help replace capacity and integrate renewables across the West. It’s a dynamic addition to the grid, and provides all of these benefits with each system install.”

  • And when he says dynamic, I think he means the most dynamic, on the order of a couple milliseconds reaction time on some battery systems, to maybe a couple of seconds on a flow battery. I hope they can use these things to reduce over production.

    • flow responds in milliseconds too. The inverter is the limiting factor

    • where did you come up with that one ?

      • Which part of what I said were you referring to?

  • This is sad. You cannot have a MW (Mega Watt) of storage. The Watt is a measure of power, not energy. The article should provide values expressed in MWh (Mega Watt hours). Energy = Power x time. Sorry for being so grumpy about this, but this should be pounded into the writers heads like the difference between “can” and “may”.

  • If an electric car can deliver, e.g., 100 kW to its motors, then this is the power equivalent of only about 400 electric car batteries for one quarter (with battery capacity in kWh not specified in the report). Presumably early days.

  • I have to agree that part of energy journalists’ responsibility is to put in appropriate perspective on both MW and MWh when talking storage. Also to put in perspective how tiny this is, in order to get off fossil fuels, U.S. Power storage probably needs to be able to serve about half of the U.S. Grid during evening hours. That’s a couple hundred GW or a couple hundred thousand MW.

  • cool to see more and more articles on storage….
    Like the other comments, they need to be expanded to show both Immediate draw as well as depth. MW/GW/TW and MWH/GWH/TWH..can only hope for the TW and TWH….
