What is the world's largest UPS?

The world's largest UPS, the 46-megawatt Battery Energy Storage System (BESS), in Fairbanks, Alaska, powers the entire city and nearby rural communities during outages. An uninterruptible power source (UPS) is an electrical equipment that provides emergency power supply to a electric load when the input power source or mains power fails.

What is an uninterruptible power supply (UPS)?

An Uninterruptible Power Supply (UPS) is defined as a piece of electrical equipment which can be used as an immediate power source to the connected load when there is a failure in the main input power source. In a UPS, the energy is generally stored in flywheels, batteries, or super capacitors.

What is an uninterrupted power supply battery?

Uninterrupted power supply batteries are an essential part of a UPS system. They are the stopgap measure designed to briefly supplement power when the main power source fails. UPS batteries are a key feature in the instantaneous response to power outages and are critical to the protection of sensitive electronics and devices.
