Thermal Energy Storage (TES) has been proposed as a load management strategy for Small Modular Reactors (SMRs) deployed on constrained grids and/or hybrid energy systems [1] The three main types of thermal energy storage are sensible heat storage, latent heat storage, and thermochemical storage. Sensible heat storage is the most commercially mature technology [2]. In sensible heat storage, there are two modes of operation: charging and discharging. For a two tank, sensible heat TES System, charging involves taking cold TES fluid from a cold tank, heating it and storing it in a hot tank for later use. Discharge involves taking the hot TES fluid from the hot tank, making use of the heat in some manner, and returning the TES fluid back to the cold tank. The theory, control strategies, and results for operating a two-tank sensible heat storage system in charging mode has been reported previously [3]. In this paper, we examine operation of the TES system in discharge mode as a peaking unit.
