Flywheel Backup Without Batteries
Overview Some emerging energy storage systems are generating quite a bit of interest at beta test sites around the country. About a year ago, Hewlett Packard's Greeley facility replaced their existing UPS system with a prototype of a new extended ride through rotary power system called the Dynamic Rotary UPS (DRUPS), built by International Computer Power (ICP). Normally, these beta tests are prone to a number of startup problems; however, the beta test for the DRUPS at this facility has been in operation for 7,500 hours and has performed without interruption since it was first installed. But the process of bringing in this new technology was not done without a few surprises.
