New technologies advancing energy storage systems help improve power system reliability by balancing utility grids and electricity distribution that smooths the integration of renewable energy from sun, wind and hydro power. Energy storage systems may include lithium-ion battery banks used with photovoltaic solar arrays, tanks of molten salt that store heat from concentrating solar (CSP), geothermal HVAC systems used in conjunction with wind and solar photovoltaic farms.

Research is being done on new science and systems integration software development.
