As part of the Town of Yountville’s environmental stewardship and commitment to environmental sustainability practices consistent with its adopted Climate Action Plan, the town has begun installing solar arrays at the Community Center, the Wastewater Treatment Plant/Corporation Yard, and the Wastewater Pump Station. When complete there will be 22,900 square feet of solar arrays, with a combined wattage of the three projects producing about 290 KW of electricity.
The project will provide fixed costs of electricity and help avoid the annual increase in cost for power over the 20-year solar contract. It is estimated to save the town over $2.2 million in energy costs over 25 years.
The project was part of the Sustainable Energy & Economic Development (SEED) program, a regional grant-funded effort to create a collaborative Request for Proposals (RFP) for solar projects in Napa, Marin, and Sonoma counties. The effort was spearheaded by the City of San Rafael and included solar projects from seven other municipalities in the North Bay, where agencies benefitted from a 12 percent reduction in bid prices through group purchasing costs. The program is modeled on a similar successful project that was implemented in the Silicon Valley.
The Yountville Solar Array Project began construction at the Community Center and Wastewater Treatment Plant the week of May 22 with conduit boring and trench, and moved into full construction of the parking canopy at the Community Center May 30. Construction of the steel structures and assembly of the modules are estimated to take about six weeks; they are scheduled to be energized in late August.
