In critical facilities, uptime is essential. When main power becomes interrupted, these applications depend on backup systems to ensure crucial equipment remains up and running. At the heart of any backup system is an uninterruptible power supply (UPS). In the event of a utility power outage, a UPS keeps electricity flowing to vital systems and equipment until auxiliary generators cycle on.
Not all mission-critical facilities are the same, though, and neither are their backup power systems. There are two primary types of energy storage within UPS systems used by mission-critical customers today — batteries and flywheels – and each have advantages and disadvantages.
GE has long helped customers design and install battery-based UPS systems and recently unveiled a new series of flywheel UPS systems to provide flexibility for all of our mission critical customers. While the tried-and-true battery-based system has traditionally been preferred by customers, particularly those in the datacenter industry, many are giving the flywheel UPS system a second look, and for good reason.
