The blast occurred about 11am Tuesday and according to a statement issued by the municipality-owned utility, an initial investigation has revealed that the Cascade building, a section of the plant that feeds coal into silos, was damaged.
“The plant was online at the time of the explosion, and operators are in the process of taking the plant offline for safety reasons and to investigate further,” CPS said.
A CPS spokeswoman told My San Antonio that one employee suffered minor scratches from the blast.
The utility said it worked quickly to evacuate the building and ensure all employees were accounted for and safe, later tweeting that the incident “will not affect customers' power supply; no safety concerns for nearby residents”
The plant’s units are scheduled to be mothballed by the end of 2018.
CPS Energy is owned by the City of San Antonio, Texas.
