According to the "Statistics", in 2023, 486 new electrochemical energy storage power stations will be put into operation, with a total power of 18.11GW and a total energy of 36.81GWh, an increase of 151%, 392% and 368% respectively compared with 2022. Second, large-scale power stations have become the mainstream.
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). Thermal energy storage systems can be as simple as hot-water tanks, but more advanced technologies can store energy more densely (e.g., molten salts ...
Electric power companies can deploy grid-scale storage to help reduce renewable energy curtailment by shifting excess output from the time of generation to the time of need.

Energy is a measure of power output over time (energy = power x time). So to calculate energy output in watt-hours we have to multiply our power rating by the number of hours our plant is running. For example, if we have a 1000MW plant, its maximum energy output in a day would be 24,000MWh (1000MW x 24 hours).
