The Sonoma Wine Company and Cogenra Solar have entered into an energy power agreement to purchase the heat and electricity generated from the installation of a new 272-kilowatt (kW) installation, now supplying renewable heat and electricity to support the company’s winery operations. Under the company’s Heat and Power Purchase Agreement (HPPA) Cogenra will maintain ownership of the solar cogeneration modules, and Sonoma Wine Company will hedge against rising and volatile electric and gas prices throughout the 15-year contract.
Former British Prime Minister Tony Blair and Vinod Khosla of
Khosla Ventures 
were among honored guests at a ceremony yesterday afternoon to flip the switch on the new solar power plant. Khosla Ventures is the lead investor in Cogenra and former British Prime Minister Blair was appointed as a senior environmental advisor to Khosla Ventures in May of this year. In his remarks Tony Blair said, “It’s up to companies that are both visionary and savvy, like Cogenra, to set us on the right path to decrease our use of fossil fuels and build a more sustainable future.”
The historic commissioning represents the first commercial-scale installation of its kind, combining proven photovoltaic and solar thermal technologies in one solar array in an important move toward more affordable and efficient utilization of solar energy.“In vetting renewable energy solutions for Graton, we found Cogenra was the perfect match — high impact without high cost,” stated Derek Benham, founder and owner of Sonoma Wine Company. “Their solar cogeneration offering serves our energy requirements for hot water and electricity, and Cogenra’s innovative financing solution provides all the benefits and savings of on-site generation without the capital costs.”
“This is a very significant milestone for Cogenra as we bring our first project online in California’s wine country and toast to a bright future with solar cogeneration,” Cogenra CEO Dr. Gilad Almogy said in his welcoming remarks. “Cogenra’s technology merges the best photovoltaic and solar thermal technologies to meet two valuable industrial needs, low cost heat and electricity. Our solution produces five times more energy and three times the greenhouse gas reductions over traditional solar offerings.”The solar cogeneration installation employs 15 individual Cogenra SunBase™ modules to displace approximately 64,000 kilowatt-hours and 12,500 therms of natural gas annually. The solar thermal element will heat water to 165°F to sustainably fuel Sonoma Wine Company’s wine tank wash and wine barrel washing system. Implementing the system will eliminate more than 120 metric tons per year of greenhouse gases, the equivalent of removing nearly 25 passenger cars from the road annually.
