how much can energy storage provide for thermal power plants
Electricity explained Energy storage for electricity generation
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.

Thermochemical systems commonly require higher temperatures to initiate energy storage but, conversely, provide higher temperatures during the release of that energy. The most relevant chemical processes for chemical energy storage in CSP plants are metal/metal oxide reactions and ammonia [ 7 ].
Thermal Power Plant
Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.
