Hybrid PV and hot water is not entirely new — the real innovativepiece at the Khosla Ventures-funded Cogenra might be the introduction of the Heat and Power Purchase Agreement (HPPA). Cogenra offersrenewable energy below utility rates while trimming natural gas andgrid-sourced electricity usage. This is akin to what Solar City and SunRun offer in residential solar PV and a host of firms like Tioga Energy or Borrego Solar offer for commercial solar.
The firm just officially unveiled a solar cogeneration project at the Sonoma Wine Company in Graton, California. Former British Prime Minister Tony Blair andVinod Khosla of Khosla Ventures were on-hand as the winery flipped theswitch on the 272-kilowatt winery installation.
