A storage device (2) for electrical power is designed for feeding current to an electricity network (3). The device comprises storage batteries (4) and converters (5) for conversion of electrical direct voltage into electrical alternating voltage. Feeding devices (6) separately feed the power produced in the plant and the electrical power stored in the storage device into the network. The electrical power stored in the storage device is used as an emergency power supply for the plant. An independent claim is also included for a method for operating a power plant.",
