The project site comprises two areas owned by SMUD, Solano 4 East and Solano 4 West, which total 2,237 acres. SMUD would construct up to 22 new wind turbine generators (WTGs), of which, up to 10 would be constructed in Solano 4 East and up to 12 in Solano 4 West. Individual WTGs would have a max height of 492 to 590 ft (150-180 meters) and a maximum rotor diameter of 446 - 492 ft (136-150 meters). Power generated by the new WTGs would be transmitted to the existing Russell Substation on Montezuma Hills Road from new, underground direct-buried electrical cable extending from Solano 4 East and West to Russell Substation. The power would be distributed from the substation via the adjacent Birds Landing Switching Station through the existing Vaca-Dixon-Contra Costa transmission line.
