This is the definition of a bad day at a power plant:
The fire comes out the wrong end of the turbine.
This is a photo of Desert Basin's Unit 2 inlet ablaze. The unit was shut down for maintenance and no one was injured. It may be a while before they can get it back up.

Update: Here's a video of the fire. Looks like it was isolated to the evap media (highly flammable stuff). I love how the news guys talk about it affecting power across the state even though the unit was already shut down for a planned outage.
