Photos of AmerenUE’s Taum Sauk Plant

Taum Sauk includes the 1.5 billion-gallon upper reservoir, in the upper left of this photo, and the generating plant itself, in the lower center. A 7,000-foot-long tunnel joins the two. Water flows through the tunnel to the plant to generate electricity.

The 55-acre upper reservoir sits 800 feet above the East Fork of the Black River.

After six years of feasibility studies and planning, UE chose 1,590-foot-high Proffit Mountain in Reynolds County for the site of the pumped storage plant, completed in 1963.

Crews work to install 1.3 million square feet of polyethylene liner inside the upper reservoir.

The lining project was completed the fall of 2004 in only nine weeks, thanks, in part, to preparation work completed during an outage two years earlier.
