The Ameren Missouri Callaway Energy Center is back in service. The plant was taken out of service on July 26 as a result of an electrical fault on the main electrical power cables exiting the plant.
The arc was caused by a ventilation louver that had dislodged and came in close proximity to the electrical cables. Inspections performed of the cabling and transformers revealed the impacts were limited to the local arc flash and major equipment replacements were not necessary.
The Callaway Energy Center generates about 20 percent of the electricity supplied to Ameren Missouri’s 1.2 million customers. While the Callaway Energy Center was out of service, power was provided to the grid by other power plants within the Ameren system.
