Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes. This paper is focused on TES technologies that
Bulk storage alters both the dispatch stack and the wholesale electricity prices in the market, changing both the dispatch of other generators and the clearing prices that they earn. A decline in revenues because of decreased capacity factor or decreased electricity prices (or both) could force retirements of existing generating plants [21], [22].
