Sonoma County Landfill Becomes 1.8 MW Solar Facility


Cenergy Power and Greenleaf-TNX team up to commission a 1.8 MW solar farm in Cloverdale, California. The project is located on a landfill in Sonoma County, and will operate under a power purchase agreement with the utility PG&E.

Large solar farms have been cropping up all over the place. One prime location that is starting to be realized is landfills. These are generally not useful for many things once decommissioned, but the open spaces provide excellent sites for solar farms. One example is the current solar plant being constructed in New York that is a whopping 10 MW.

Now, Cenergy Power and Greenleaf-TNX have announced that they have successfully commissioned a 1.8 MW solar facility located on a Sonoma County landfill in Cloverdale, California. It is known as the Cloverdale Solar Project, and was designed, engineered, and constructed by Cenergy Power. Cenergy will also provide ongoing operations and maintenance services to the site.

The feed-tariff (FiT) project encountered major obstacles with the landfill site, but was ultimately able to achieve its “permission to operate” prior to an interconnection deadline of June 2014. “We were not allowed to grade the area or penetrate the landfill due to strict guidelines advanced by Sonoma County and the State of California,” stated Andrew Goldin, Senior VP of Operations for Cenergy. “This added complexity to the project’s engineering and interconnection requirements, which were overcome with creative solutions and a great team effort between Cenergy and Greenleaf,” said Goldin. 

“Despite all the challenges confronting this project, we are extremely pleased to have successfully commissioned another FiT project and continued our very good partnership with Cenergy Power,” noted Charlie Fiechter, Partner at Greenleaf-TNX Management. “We are looking forward to commencing construction on an another upcoming FiT project together with Cenergy later this month,” said Fiechter.

Greenleaf-TNX will sell the power generated by the Cloverdale Project to PG&E under a 20-year power purchase agreement. The project is designed to generate over 2.7 million kWh of energy annually, the equivalent of preventing 3,000 tons of CO2 emissions.
