Cogenra Completes 272 kW Cogeneration Photovoltaic Installation


Cogenra Solar, a provider of distributed solar cogeneration systems and renewable energy service solutions, has inaugurated a 272 kW solar cogeneration project at the Sonoma Wine Co. in Graton, Calif.

The project will supply heat and electricity to support the company's winery operations. The commissioning represents the first commercial-scale installation of its kind, combining proven photovoltaic and solar thermal technologies in one solar array, according to Cogenra Solar.

The solar cogeneration installation employs 15 individual Cogenra SunBase modules to displace approximately 64,000 kWh and 12,500 therms of natural gas annually. The solar thermal element will heat water to 165 degrees F to fuel Sonoma Wine Co.'s wine tank wash and wine barrel washing system.

The company will purchase the heat and electricity generated from the installation at guaranteed energy rates from Cogenra under the company's Heat and Power Purchase Agreement (HPPA). Under the HPPA, Cogenra will maintain ownership of the solar cogeneration modules, and Sonoma Wine Co. will hedge against rising electric and gas prices throughout the 15-year contract.
