Fuel Cell Projects
Sonoma County Administration Center
2680 Ventura Ave.
Santa Rosa, CA
 The fuel cell cogeneration facility at the Sonoma County Administration Center is currently under construction. The facility will host the first 1.4MW rated DFC1500 FuelCell Energy power plant. This system will run on natural gas, and will help Sonoma County achieve its goals of promoting clean and efficient electricity. The exhaust heat from the fuel cell will be recaptured through an air to hot water heat exchanger. The hot water will supplement the hot water needs of the County by tying into the existing hot water loop. The electricity from the fuel cell is transformed up from 480V to 12KV, and interconnected into the County 12KV electrical loop, operating in parallel with PG&E.
California State University East Bay - PG&E Fuel Cell Project
Hayward, CA
 Following the recent approval by the California Public Utilities Commission (CPUC) for PG&E to pursue utility owned fuel cell installations, OHR Energy was awarded the EPC contract to Engineer, design and install a FuelCell Energy 1.4MW DFC1500 fuel cell power plant. The system will be a utility owned fuel cell, located on the campus of CSU-East Bay (CSU-Hayward Hills). The system will include a hot water heat recovery system. CSU-East Bay plans to utilize the waste heat for heating a swimming pool. They also plant to utilize the waste water for landscape irrigation. The systems will be operational in late 2010/early 2011. In conjunction with the installation of the fuel cell power plants, CSU-East Bay plans to incorporate the fuel cell technology in to their respective curriculums to teach students and the public about the benefits of fuel cell systems.
The CPUC approval acknowledged that the installation of fuel cells on university campuses will help to advance the development and understanding of fuel cell technology. Further, the CPUC noted the important role of fuel cells in the State's future energy mix, as illustrated by the support of Governor Schwarzenegger for fuel cell projects.
University of California, San Diego
9500 Gilman Drive
La Jolla, CA
 OHR Energy was chosen as the EPC contractor to design, engineer, construct & install a 2.8MW fuel cell cogeneration system. At UCSD, OHR Energy will be the first to install the FuelCell Energy 2.8MW DFC3000 anywhere in the country. The fuel cell at UCSD is part of a larger project that involves the clean up, CO2 removal and injection of anaerobic digester gas from the Point Loma waste water treatment plant into SDG&E natural gas lines. That gas is then consumed in the fuel cell at UCSD, resulting in a truly renewable fuel cell power. The waste heat from the fuel cell exhaust will be used in an absorption chiller, which will supplement the chilled water demand currently supplied by electric chillers. The chilled water from the fuel cell absorption chilled will be tied into the existing chilled water lines that run throughout the campus. Engineering & design are underway, and construction will begin during Q4 of 2010. The project will be completed and commissioned July 2011.
