Document Description
The Project site comprises two areas owned by SMUD, Solano 4 East and Solano 4 West, which total 2,549 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 maximum height of 492 to 590 feet (150 to 180 meters) and a maximum rotor diameter of 446 to 492 feet (136 to 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.
