Grid energy storage, also known as large-scale energy storage, is a set of technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed. They further provide essential grid se. Roles in the power gridAny must match electricity production to consumption, both of which vary significantly over time. Energy derived from and varies with the weather on time scales ranging from less th. .
Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in , and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. Th. .
The (LCOS) is a measure of the lifetime costs of storing electricity per of electricity discharged. It includes investment costs, but also operational costs and charging costs. It de.

Ravenswood was originally built and owned by of New York Inc. (Con Edison) in 1963. The first two units constructed in 1963 were Ravenswood 10 and 20, each having a generating capacity of approximately 385 . Then, in 1965, Ravenswood 30 (commonly called "") was commissioned with a generating capacity of nearly 981 megawatts. A new 1,000 MW unit was originally planned to be located on the north side of the
