This presentation provides an overview of the impact of intermittent renewable energy technologies (notably solar and, especially, wind power) on the electric power grid. Multi-hour energy storage (ES) technology options are described; and their technical and economical characteristics are compared. The use of cool thermal energy storage (TES), in both demand-side (electricity user) and supply-side (electric utility generator) applications, is examined, with performance and economic results highlighted. Examples illustrate the varied means by which TES can expand the use of renewable energy resources.
