Corps awards contract for transformer replacement at Gavins Point hydropower plant

Gavins Point Dam

Yellowstone Electric Co. has won a US$1.8 million contract from the U.S. Army Corps of Engineers to install three generator step-up transformers and related equipment at the 132.3-MW Gavins Point hydropower plant in South Dakota’s Missouri River.

The Corps’ Omaha District most recently called for bids in July for work that includes the removal of three 115-kilovolt GSU transformers. Yellowstone Electric will then replace them with government-furnished transformers on existing transformer pads.

The installation also includes a new oil containment system, two firewalls between transformers, and a 115-kV take-off tower support structure.

Gavins Point Dam is one of several Corps projects receiving work following 2011 flooding in the Missouri River Basin. The Corps has already awarded a contract to Futurenet Group Inc. in 2012 for replacement of tailrace erosion protection at Gavins Pointand also took bids in August to rehabilitate spillway gates.
