Dive Brief:

• Commercial energy storage capacity will grow by about 720 MW by 2020, or about 34% a year, according to GTM Research.
• The growth will be partly driven by storage cost reductions and the increase in solar. Other drivers include include demand charge reductions for commercial and industrial customers, frequency regulation and state incentives.

Dive Insight:

Energy storage has the potential to make the grid much more efficient and help foster increasing amounts of intermittent renewable generation like wind and solar. The energy storage market is roughly at the same place that solar was in 2005, according to GTM Research.

"The commercial energy storage market is still in its earliest days, but we're starting to see real opportunity emerge for companies that can selectively pursue attractive markets and successfully monetize multiple value streams," Shayle Kann, GTM Research senior vice president, said.
