An emergency power system is an independent source of electrical power that supports important electrical systems on loss of normal power supply. A standby power system may include a standby generator, batteries and other apparatus. Emergency power systems are installed to protect life and property from the consequences of loss of primary electric power supply. It is a type of continual power system.

They find uses in a wide variety of settings from homes to hospitals, scientific laboratories, data centers,^[1] telecommunication^[2] equipment and ships. Emergency power systems can rely on generators, deep-cycle batteries, flywheel energy storage^[3] or fuel cells.^[4]^[5]
