[1] The Advanced Power and Energy Program (APEP) at UC Irvine has full control over the “Level I” sites.In addition, the UC Irvine Central Plant (referred to as a “Level II” site), located less than 0.5 mi from the Level I site, has made available and is pursuing with APEP installation of 1 MW worth of Distributed Generation.Finally, the University Research Park (referred to as “Level III”—a 200 acre light industrial commercial business park located less than 0.5 mi from the Level I site, is participating with APEP in the installation of distributed generation with and without CHP for purpose of reliability.The Level II and III sites offer additional potential test sites which can serve as “field tests” for distributed generation.The close proximity to the Level I site provides convenient monitoring ability.
