The pipeline for energy storage projects in the U.S. has doubled this year, ballooning to 32.9 gigawatts, according to the latest U.S. Energy Storage Monitor from Wood Mackenzie Power & Renewables and the Energy Storage Association.
While not all of the projects will come to fruition, this is a clear signpost that developers are bullish on energy storage. California continues to lead in total pipeline; however, the report points to surging interest across a variety of new state markets including Missouri, Mississippi, Nebraska, and Oklahoma.
In total, the U.S. saw 136.3 megawatt-hours of storage deployed in the third quarter of the year, up from 44 megawatt-hours in Q3 2017. By the end of the year, Wood Mackenzie forecasts 686 megawatt-hours of energy storage will be deployed in 2018.
We're seeing our energy storage developer clients clearly move towards the longer-duration grid battery projects and we're excited to support their growth as we navigate a rapidly shifting North American market in search of the best talent in the industry.
The types of projects being deployed have shifted over the past year as well. For example, the third quarter’s front-of-meter, utility-scale battery projects were down 14 percent year-over-year when measured in terms of their megawatt power ratings. But in terms of megawatt-hours — how long they can provide their rated power capacity — the projects deployed in the third quarter were up 178 percent compared to the same quarter last year.
