Electricity generation is the process of generating electric power at power stations. This is done ultimately from sources of primary energy typically with electromechanical generators driven by heat engines from fossil, nuclear, and geothermal sources, or driven by the kinetic energy of water or wind. Other power sources are photovoltaics driven by solar insolation, and grid batteries.
By definition, a Battery Energy Storage Systems (BESS) is a type of energy storage solution, a collection of large batteries within a container, that can store and discharge electrical energy upon request.
