The U.S. Patent Office recently awarded Sure Power Corp., Danbury, Conn., a patent for its onsite power generation systems. Capable of providing 99.9999%—or "six nines"—availability over 20 years, the systems have less than 1% chance of failure.

"Our systems can operate indefinitely without any reliance on the existing utility grid because they utilize our unique version of RAID (Redundant Array of Independent Devices) architecture and our proprietary DC bus system," said Bill Cratty, chief technology officer and co-founder of Sure Power. "Receiving a U.S. patent underscores the ability of our technology to prevent the kinds of power woes that have plagued California businesses for the past year."

Designed for onsite use by energy-reliant businesses that need a constant flow of computer-grade electricity, these systems are ideal for data centers, telecom hotels, high-tech manufacturing operations, and utilities. Available in several configurations capable of generating from a few hundred kilowatts to tens of megawatts of electricity, the units also provide high-availability cooling through a partnership with Trane, the nation's largest provider of applied commercial and industrial air conditioning systems, equipment, controls, service, and parts.

According to Sure Power, after enduring power outages that left it unable to service its largest corporate customers, the First National Bank of Omaha (FNOB), the nation's largest privately owned bank and seventh largest credit card transaction processor, installed one of its systems as the primary power source for its new 200,000-sq-ft technology center. This unit generates 100% of the critical load electricity for the FNBO's computers and storage devices used to process millions of daily credit card and banking transactions. The system has been running without interruption for more than two years and has provided electricity though numerous grid outages and other utility problems.
