White Pine Renewables Completes Largest Floating Solar Farm In The U.S. Project Will Provide Clean Energy to the City of Healdsburg Healdsburg, CA /PRNewswire/ - White Pine Renewables is pleased to announce the completion of the Healdsburg Floating Solar Project. The project will deliver clean energy to the City of Healdsburg, Calif., under a 25-year power purchase agreement. At 4.78 MW(dc) and sited on ponds at the City's wastewater treatment plant, the project is the largest floating solar project completed in the United States to date. The electricity generated by the project will cover approximately 8% of the City's total energy demand and is an important part of the City's plan to reach 60% renewable energy before 2030. Additionally, siting the solar panels on the ponds avoids using land for the project and will reduce evaporation and algae growth, benefitting the surrounding vineyards that rely on the treated water for irrigation.
