What is EPRI's energy storage research program?

This paper presents recent key findings of EPRI’s Energy Storage Research Program, which are intended to advance the understanding of the current near-term costs, value, and benefits of energy storage systems in various applications.

What is an electric energy storage system?

Electric energy storage systems have applications along the entire electric enterprise value chain, as illustrated in Figure 1-1.

Are energy storage systems changing?

Rapid change is underway in the energy storage sector. Prices for energy storage systems remain on a downward trajectory. The deployment of energy storage systems (ESSs) -- measured by capacity or energy -- continue to grow in the U.S., with a widening array of stationary power applications being successfully targeted.

Are energy storage systems economical?

Each type of energy storage technology has its own capital cost and operating cost parameters, which are described in the full paper. In general, based on present-day technology, some energy storage systems will not be economical because more technology development is needed to lower their capital costs.

What is EPRI's energy research portfolio?

EPRI’s energy research portfolio offers collaborative projects, customized research opportunities, thought leadership, and innovation to help energy companies simultaneously decarbonize the energy sector while maintaining a resilient, reliable, and affordable power system on which society depends.

What drives new interest in electric energy storage systems?

EPRI, Palo Alto, CA, 2010. 1020676. A confluence of industry drivers—including increased deployment of renewable generation, the high capital cost of managing grid peak demands, and large capital investments in grid infrastructure for reliability—is creating new interest in electric energy storage systems.
