Understanding grid-side energy storage involves delving into various technologies and their applications. These systems serve as a bridge between energy generation and consumption, allowing for energy to be stored during periods of low demand and released when demand escalates. 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.
