The U.S. Army Corps of Engineers has awarded a contract worth US$10.98 million to Interstate Electrical Contractors Inc. for a switchyard upgrade at the 320-MW Fort Randall hydropower plant in South Dakota.
The Corps’ Omaha District most recently solicited bids for the work in January in a tender reserved exclusively for small businesses.
Per the contract, Interstate Electrical Contractors will upgrade the capacity of Fort Randall’s switchyard to meet the Western Area Power Authority’s updated requirements. The project also includes the replacement of antiquated oil-filled equipment with modern gas-insulated equipment. The work is expected to take two years.
The Corps also recently called for bids for the mechanical and structural rehabilitation of bridge cranes and a lifting beam at Fort Randall. It awarded a contract in 2012 to Flowmeter Services to supply flow meter panels at the plant.
