Big Growth In US Grid-Scale Energy Storage Market

Philip Hiersemenzel, spokesman for Younicos, stated that Germany could be using 60 percent renewables if the right storage tech were in place. Startling as this announcement seems, the US is not as far behind as people think.

The U.S. is surging ahead in terms of adopting battery storage. In 2013-2014, U.S. companies installed, or were in the process of installing more than 300 MW of energy storage capacity. The largest is Southern California Edison’s Tehachapi Energy Storage Project. It is a 8-MW system capable of supplying 32 megawatt-hours of electricity to the grid.

“What we lack is a national energy policy. That’s going to create an environment in which people will be willing to invest and know that 10 to 20 years down the road they can count on a rate of return.” — Allan Hoffman, a former senior executive with the U.S. Department of Energy.
“One of the shots that was heard around the world was AB 2514, which is a California mandate for the minimum amount of energy storage the utilities have to install by 2020. That minimum allocated across the three major IOUs in California — Southern California Edison (SCE), Pacific Gas & Electric (PG&E) and San Diego Gas and Electric (SDG&E) — totals 1.325 gigawatts,” according to John Jung, CEO of the energy storage software, services & systems company GreenSmith.

GreenSmith is battery agnostic. It develops the software used in battery storage facilities. By the end of this year, it will have integrated a dozen battery storage units to the grid. That represents 23 MW of installed capacity deployed in four states.
