A small explosion occurred at a power plant in Queens on Wednesday night, though no one was injured.

The Fire Department said the explosion took place about 7:30 p.m. at the US Power Gen plant on 20th Avenue in Astoria. More than 80 firefighters arrived at the scene, but it was quickly determined that the explosion was contained in one area and did not cause a fire, the Fire Department said.

In a statement, the company said that Unit 4 at the Astoria generating station “tripped off line due to a tube rupture in the reheat boiler, resulting in window breakage and noticeable shaking of the building.”

The company said that one person was taken for medical evaluation, and that the damaged unit would remain out of service for an undetermined amount of time. The station has three other units that have continued operating and supplying electricity without any hiccups since the explosion.
