NEW ORLEANS - New Orleans firefighters responded to the Sewerage and Water Board's main power plant after a spike in voltage caused circuit breaker to catch fire.

According to a report from WWL, the fire broke out around noon at the SW&B Carrollton PowerPlant.

Paul Rainwater with the S&WB’s emergency interim management team told WWL that testing Turbine No. 4 caused the explosion at the plant. 

Rainwater said that the explosion will not impact the city's water, sewer or drainage systems. No one was injured in the fire, according to NOFD.

Turbine No. 4, a 1920s-vintage, steam-powered turbine, hasn't operated at full power since Hurricane Katrina and was taken offline completely in 2012.
