In January 2021, we successfully completed a 4.78-megawatt floating solar installation for the City of Healdsburg, located in Sonoma County, California. This innovative project was designed to address the city’s growing demand for sustainable energy while maximizing the use of existing water infrastructure.

The floating solar system now supplies approximately 8% of Healdsburg’s total electricity needs, significantly advancing the city’s renewable energy goals. Beyond the clean energy benefits, the installation also delivers important environmental co-benefits. By covering a portion of the water surface, the system helps suppress the growth of harmful algae blooms, which can compromise water quality and ecosystem health. Additionally, the reduced sunlight penetration and evaporation contribute to improved efficiency in the city’s recycled water operations.

The enhanced quality of recycled water directly supports the region’s agricultural industry—particularly local vineyards and farms—by providing a more reliable and sustainable source of irrigation. This project reflects the City of Healdsburg’s commitment to environmental stewardship and serves as a model for how floating solar can simultaneously address energy, water, and agricultural needs.
