Pacific Gas and Electric has piloted the use of 6MWs of Sodium Sulfur batteries on their distribution system. These projects have tested the bulk system use of energy storage on a variety of applications including renewable smoothing, load shifting, local islanding and frequency regulation. In the case of the frequency regulation the projects are the first energy storage device to participate in the California Independent System Operator (CAISO).
