Investing in Clean Energy at Bagnell Dam


Construction crews have poured the final yards of concrete on Ameren Missouri’s $53 million reliability upgrade to the historic Bagnell Dam, a major source of clean energy for the state. The project includes installation of a series of new anchors and concrete on the downstream side of the dam, which improves overall safety, efficiency and reliability of the 85-year-old structure.

Initial work began March 2017 and included the removal of timeworn concrete from the surface of the dam. Crews then installed 67 post-tensioned anchors, strengthening the connection to bedrock. More than 66 million pounds of new concrete was poured to further weigh down the dam. This is the first major structural update in more than 30 years and builds on Ameren's expertise in enhancing dam safety.
