The Superconducting Magnetic Energy Storage System (SMES) is a system that can store and discharge electricity continuously as needed. Superconductivity is the flow of electric current without electrical resistance and is achieved when electrical resistance is naturally eliminated by cooling certain elements and chemical compounds. In a superconductive state, a constant magnetic field is continuously produced even if electricity is conducted, and as a result, electrical energy can be stored as magnetic energy.

When SMES is used in factories, it can be used as a backup electricity source that can compensate for load damage caused by an instantaneous voltage drop due to lightning or other factors.

Another feature of this system is that it can reliably supply power even in locations where the frequency fluctuates because it can also support drastic load changes.

Chubu Electric Power and Furukawa Electric are establishing SMES system that can supply 10,000 kilowatts of power.
