Charlotte, N.C., July 28, 2010 — ABB has completed a comprehensive project to provide power equipment for the AmerenUE Taum Sauk Pump Storage Hydro plant in Missouri.

ABB installed a complete integrated instrumentation, control and electrical system package to help retrofit the AmerenUE 440 MW plant, allowing for improved functionality, reliability and modernization. The total project value was over $11 million.

“ABB’s replacement of the plant controls — including installation in the new upper reservoir of the most advanced-level monitoring, control and protection system in the country — significantly improves the safety and reliability of the Taum Sauk Power Plant,” said Mark Birk, vice president, Power Operation for AmerenUE.

ABB began this project with a full audit of existing equipment of the 40-year-old AmerenUE Taum Sauk power station. This pump storage hydro plant is comprised of two units, both of which ABB upgraded.

The audit began with the general objective of evaluating the plant against modern designs and making recommendations to improve reliability, operations, maintainability and personnel safety developed from years of working on grass roots pump storage plants across the world.

ABB made the announcement at the HydroVision International conference and exhibition event in Charlotte.
