Missouri nuclear power plant back in service

Ameren Missouri Callaway Energy Center back in service electrical fault nuclear power plant

Ameren Missouri (NYSE: AEE)’s Callaway Energy Center has been restored to service after being taken offline as a result of an electrical fault on the main electrical power cables exiting the plant. The 1,190 MW nuclear power facility has been out of service since July 26.

According to Ameren, inspection of the cable and transformers showed no major equipment replacements were necessary after a dislodged ventilation louver caused an arc.

The nuclear plant generates about 20 percent of the electricity supplied to Ameren Missouri’s 1.2 million customers, according to the company. The company used other power plants in the Ameren system to provide power to the grid while the Callaway Energy Center was out of service.
