Energy storage systems allow energy consumption to be separated in time from the production of energy, whether it be electrical or thermal energy. The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage).

In district cooling, thermal energy storage tanks are used to store cooling energy at night where the electricity is cheaper. During the day, the stored cooling energy is released. By doing so, the operating cost of the district cooling plant is reduced. Some people misunderstood that a district cooling system with thermal energy storage …
Thermal energy storage is a strategic technology that enables end-users to decouple the electric demand associated with a building''s air conditioning system from its production. At a basic level, a thermal storage system allows the building owner to shift energy usage from periods of high energy cost (on-peak) to periods of low energy cost ...
Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics ).

Thermal energy storage (TES) refers to heat that is stored for later use—either to generate electricity on demand or for use in industrial processes. Concentrating solar-thermal power (CSP) plants utilize TES to increase flexibility so they can be used as "peaker" plants that supply electricity when demand is high; as "baseload" power ...
Thermal energy (stored heat or stored refrigeration) is a lower form of energy than electricity or stored hydraulic (potential) energy.
