Solano 4 Wind Project scope

  • Removal of 23 Vestas V47 wind turbines (0.66 megawatts each, 15 megawatts total).
  • Installation of 19 Vestas V150 wind turbines (4.5 megawatts each, 85.5 megawatts total).
  • Increases capacity and energy by 70.5 megawatts and 335 gigawatt hours per year.
  • The combined Solano Wind Project will generate 300 megawatts and 880 gigawatt hours per year. This is a 61 percent increase in the project annual energy generation.
  • New Vestas V150 Turbine Dimensions:
    • Total turbine height, 590 feet
    • Turbine hub height, 344 feet
    • Turbine rotor diameter, 492 feet

SMUD has long partnered with Vestas, a world leader in sustainable technologies, to produce wind power generation. The re-powering project supports SMUD’s goal to reach zero carbon emissions in its power supply by 2030 and will help SMUD reach 60 percent renewable energy by 2025.Construction is expected to be completed by spring of 2024.
