They must use electricity supplied by separate electricity generators or from an electric power grid to charge the storage system, which makes ESSs secondary generation sources. ESSs use more electricity for charging than they can provide when discharging and supplying. . Battery storage is a technology that enables power system operators and utilities to 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. . Electrical Energy Storage (EES) systems store electricity and convert it back to electrical energy when needed. 1 Batteries are one of the most common forms of electrical energy storage. The first battery, Volta's cell, was developed in 1800. ESSs provide a variety. . This Guide is provided to aid interconnection customers with the Pacific Gas and Electric Company (PG&E) interconnection process for energy storage devices applying under PG&E's Electric Rule 21.

Energy storage systems help balance wind power output. This smooths power delivery to the grid. They store excess energy from wind turbines, ready for use during high demand, helping to achieve energy independence and significant cost savings. The growth of wind energy brings both opportunities and hurdles.
