Well, here's the shocker: substation cabinets physically cannot store energy. These metal enclosures primarily house circuit breakers, transformers, and monitoring equipment - components designed for power distribution, not storage.

Although energy storage does not produce energy—in fact, it is a net consumer due to efficiency losses—it does potentially allow greater use of variable renewables by shifting energy from periods of low demand to periods of high demand, which reduces curtailment and eases.

In the realm of high voltage switches, capacitors and inductors serve as the primary energy storage components. Capacitors store energy by accumulating electric charge between two conductive plates separated by an insulating material.
