Arizona contractor to tune power stabilizers, exciters at 132.3-MW Gavins Point Dam

Gavins Point Dam

The U.S. Army Corps of Engineers has awarded a contract to William Koronka of Phoenix, Ariz., to perform tuning of power system stabilizers and exciters at 132.3-MW Gavins Point Dam on the Missouri River.

The Corps’ Omaha District took bids in July for the work.

Under a $49,075 contract, Koronka is to perform tuning of three power system stabilizers and fine tuning of three exciters at Gavins Point. In addition, the contractor is to provide one power system stabilizer card designed by Siemens to work with existing equipment. Two other PSS cards are to be provided by the government.

The Corps took bids in March to perform load testing of station service and power plant control system batteries at Gavins Point. Last year, it awarded a contract to Yellowstone Electric Co. to install generator step-up transformers and related equipment at the project.
