SOLANO WIND

• Year2022-2023

• LocationRio Vista, CA

Clark Bros. is proud to have partnered with the Sacramento Municipal Utility District (SMUD) on the Solano 4 Wind Project, a major clean energy infrastructure upgrade located near Rio Vista, California. The project involves the replacement of 23 aging wind turbines with 19 state-of-the-art Vestas V150 turbines, each with a capacity of 4.5 megawatts (MW). Once fully operational, Solano 4 will add 85.5 MW of clean, renewable energy to SMUD’s portfolio—enough to power approximately 40,000 homes annually. This marks a significant step in supporting California’s clean energy goals and SMUD’s commitment to achieving a zero-carbon future by 2030.

Clark Bros. provided comprehensive civil construction services, including:

•  Grading and site preparation across multiple turbine locations
•  Construction of new access roads and crane pads
•  Foundation excavation and backfill
•  Installation of underground electrical infrastructure
•  Coordination with turbine delivery and erection teams

Construction activities were completed between 2022 and 2024, with turbines entering commercial operation in spring 2024. Clark Bros. is honored to support projects that move California toward a more sustainable and energy-resilient future.
