Most forms of uninterruptible power supply (UPS) can be either powered by battery or flywheel energy. These are ready for immediate use at the instant that the mains electricity fails, but the relatively small and finite amount of stored energy they contain makes them suitable for short periods of use, typically in the order of a few dozen minutes to a couple of hours depending on the actual load.
EnerSys is a stored energy systems and technology provider for industrial applications. The company manufactures reserve power and motive power batteries, battery chargers, power equipment, battery accessories and outdoor equipment enclosure systems.
When power loss occurs, the rectifier simply drops out of the circuit and the batteries keep the power steady and unchanged. When power is restored, the rectifier resumes carrying most of the load and begins charging the batteries, though the charging current may be limited to prevent the high-power rectifier from damaging the batteries.
Flywheel power storage systems in production as of 2001 had storage capacities comparable to batteries and faster discharge rates. They are mainly used to provide load leveling for large battery systems, such as an uninterruptible power supply for data centers as they save a considerable amount of space compared to battery systems.

A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of energy storage technology that uses a group of batteries in the grid to store electrical energy.
AC power will periodically switch directions, which makes it harder to manage in a battery. The AC power goes through a power management system and is transformed into direct current (DC) power, power that flows in one direction and the power most commonly used in batteries. The DC power is then stored inside of the Energy Storage System (ESS).
A 128-megawatt battery system at Robins Air Force Base in Warner Robins, about 20 miles south of Macon. The batteries will primarily be charged by an existing Georgia Power solar array at the base.
In July 2013, Saft was awarded a $6.5 million contract to supply high power lithium-ion batteries for the Lockheed Martin F-35 Lightning II [27] Saft also supplies the battery for the Exagon Furtive-eGT, a four-seat electric sports car produced by Exagon Motors. The battery is capable of withstanding 3,000 charge cycles while conserving 80% of ...
