AVILA BEACH, Calif. - A small fire was quickly extinguished today on a back-up diesel generator that was out of service at Pacific Gas and Electric Company’s (PG&E) Diablo Canyon Power Plant.

There was no risk to plant safety or public health and no injuries occurred. Units 1 and 2 were not impacted and remain at 100 percent power.

The Unit 1 back-up diesel generator involved in the incident was out of service at the time for planned maintenance. The brief fire began when a piece of insulation became heated during testing of the equipment. The generator was shut down immediately, effectively extinguishing the fire.
