On July 19, local time, a transformer exploded and caught fire at the Hoover Dam hydropower station on the border between Nevada and Arizona.
The accident caused no casualties.
The Associated Press reported that a transformer at the Hoover Dam exploded on the 19th and produced flames and smoke.
Federal Bureau of Reclamation official Jaclyn L. Gould said the fire started around 10 a.m. that day and was extinguished within half an hour.
CNN quoted Gould as saying that no employees or tourists were injured, the hydroelectric plant was still generating electricity and the power grid was not threatened.
