American Governor receives multi-year deal to upgrade control systems at six Corps hydropower projects

The U.S. Army Corps of Engineers has awarded equipment supplier a $4 million contract to supply standardized digital governor conversion packages for all its hydropower projects on the Missouri River.

The five-year deal, awarded by the Corps’ Omaha District, includes overhauls on 39 generating units in six plants. The Corps most recently sought bids for the work in September.

Details of the contract include:

  • 494.3-MW Big Bend (eight units) — Upgrades to Pelton governors with fixed-blade propellers
  • 185.3-MW Fort Peck (five units) — Upgrades to Woodward governors with Francis turbines
  • 320-MW Fort Randall (eight units) — Upgrades to Woodward governors with Francis turbines, and 10 control room human machine interfaces (HMI)
  • 583.3-MW Garrison (eight units) — Upgrades to Woodward and Pelton governors with Francis turbines, and six control room HMIs
  • 132.3-MW Gavins Point (three units) — Upgrades to Woodward governors with Kaplan turbines
  • 118.2-MW Oahe (seven units) — Upgrades to Pelton governors with Francis turbines

The Pennsylvania-based company said it will supply programmable logic control (PLC) digital governor systems using its “H6B” math model. American Governor will also be responsible for providing complete system design specifications, controller hardware, spare parts, field service support and training.

American Governor recently received a similar five-year deal to convert 146 units in the Corps’ North Pacific Region.
