Ring main unit cannot store energy

Why does the ring main unit store energy RMUs are designed to provide uninterrupted power supply by using a "ring" configuration. This shall enclose the main components: two switches connecting the load to the main conductors and a fusible switch or circuit breaker arranging the distribution of m lenges of electrical distribution. Ring Main Units (RMUs) are electrical distribution devices that efficiently manage energy flow within electrical networks, 2. Energy storage in RMUs can occur through integration with battery systems or other forms of storage technologies, 3. Ring Main Units are compact modules that are gas-insulated and sealed, comprising main switching devices and ancillary components to ensure continuous secondary power distribution.
