The City of Healdsburg completed a 4.78 megawatt solar array on the recycled water treatment ponds in January 2021 at the Wastewater Treatment Facility a few miles west of Healdsburg. The project provides 8% of the City's energy needs, as well as cuts harmful algae bloom on the ponds, which improves the quality of water for local vineyards, farms, and residents that use the recycled water.

Given the need for shade and renewable energy, the floating solar project provides an important co-benefit to City operations, recycled water customers, and the community.

The Electric Department connected its first photovoltaic system in 2002, and today has over 360 customer-owned solar arrays and 60 battery systems interconnected in city limits.

City staff continue to increase the amount of renewable and carbon free energy provided to Healdsburg’s electric customers, such as the Antelope project to develop additional solar energy based near Lancaster, California. This additional solar will increase the City’s overall renewable energy sources by roughly 8% and help to reduce GHG emissions associated with market purchases. The Antelope Solar project was completed in late 2022.

Additionally, the City finalized a contract with South Feather Power and Water for both large and small hydro resources within the Sierras. This contract supplied Healdsburg with zero-carbon hydro generation throughout 2022. This project is expected to meet roughly 6% of Healdsburg annual energy needs and replace market purchases based mostly on natural gas generation.

Currently, the City is working with other owners of the Lodi Energy Center natural gas plant to incorporate green hydrogen and reduce carbon emissions from the plant.
