Pleasantville, Thornwood and White Plains emergency responders are at the scene of the Con Edison substation on Manville Road where a brush fire was reported earlier this evening.
"There was an explosion," confirmed Pleasantville Fire Chief Bruce LaMonica at the scene.
He said the explosion did not involve transformers, but did cause a brush fire in the area off the street. Crews were still dousing the area with water a few hours later as a precaution, but the flames have been extinguished.
Con Edison is also at the scene assessing possible hazards.
Pleasantville Police Chief Richard Love said the cause of the explosion may involve a feeder line.
The case of the explosion is unknown at this time.
While the flames have since been extinguished, he said some black soot remains at the scene.
Repairs may continue into the overnight.
Members and apparatus from the Chappaqua Fire Department are on standby at the Washington Avenue headquarters of the Pleasantville Fire Department.
Love said no residents have been evacuated in the area, nor have any lost power.
However, Manville Road is closed from the intersection of Route 117 to Academy Street.
"It's all under control," said Love.
