Ameren Plans to Rebuild Taum Sauk Pumped-Storage Plant

---

Researched by Industrial Info Resources (Sugar Land, Texas). AmerenUE, a subsidiary of Ameren Corporation (NYSE:AEE) (St. Louis, Missouri), is conducting planning and scheduling to rebuild the upper reservoir at the 450-megawatt Taum Sauk Pumped-Storage Hydro Station (Annapolis, Missouri). The original reservoir had collapsed in December 2005 after faulty gauges allowed it to overflow.

A typical pumped-storage facility consists of an upper and lower reservoir. At times of low demand, water is pumped into the upper reservoir and is released back into the lower reservoir through a turbine, generating electricity during times of higher demand.

The plan is to rebuild the upper reservoir with new safety features, such as a roller compact concrete (RCC) monitoring system, new water-level sensors and liners, overflow release structure to protect against damage if the system fails, and video cameras that constantly observe the water level.

Construction is scheduled to start fall 2007, with the plant’s return to service scheduled for 2009.

Paul C. Ritzo Associates (Annapolis, Missouri) is being retained by Ameren to provide conceptual and technical design, plus construction management service for the rebuild.
