Load Following
In some cases, there are severe changes in total load associated with a region or a specific user, for example power demand increases abruptly in several steps in the early morning. An arc furnace, where metal is fused and melted for reuse, has several periods of demand during a day. An electricity storage system can act as a buffer that isolates the rest of the power grid from these frequent and rapid power changes. VAR support and spike control are also important capabilities of a storage system for the arc furnace amelioration. The latter is a bonus value for device that it has because of the power conversion system. This capability is independent of the energy part of the storage system.
