June 10th, 2010: Grocery Store Thermal-PPA Billing Begins

The Williamson Street Grocery Cooperative located at 1221 Williamson Street in Madison, Wisconsin is now offsetting its natural gas use (and eliminating approximately 5 tons of CO2 from the atmosphere) via a solar hot water system installed by Resource Solar and financed under a solar thermal power purchase agreement (Thermal-PPA).  Billing commenced today and will continue monthly (at a fixed rate) for 6 years.  The Co-op will buy the system at the end of the 6-year period for less than a third of what a new system would cost, yet have 80% of system life left.  To read an article in the Willy Street Newsletter about the system, please click on the following:  Reader, Feb 2010
