Fire traps workers beneath Colorado power plant
Five contractors were working in an underground penstock, or pipeline, at the Cabin Creek Station, where the fire broke out. Xcel said the workers climbed to a safe distance from the blaze and were communicating with plant operators by radio.
The 48-inch diameter pipe was opened to get air into the pipe, Xcel spokeswoman Ethnie Groves told reporters at a news conference.
Firefighters from the Clear Creek County Fire Authority were battling the blaze. The plant was shut down for routine maintenance at the time, the company said. The cause of the fire was not immediately known.
The pipeline is between 1,500 and 2,000 feet (460 and 610 meters) below ground and carries water from a reservoir to power turbines inside the plant.
The power station, which is west of Denver, has two turbines and a generating capacity of 324 megawatts.

California's solar energy gains go up in wildfire smoke
LOS ANGELES - Smoke from California’s unprecedented wildfires was so bad that it cut a significant chunk of solar power production in the state. Solar power generation dropped off by nearly a third in early September as wildfires darkened the skies with smoke, according to the US Energy Information Administration.
Those fires create thick smoke, laden with particles that block sunlight both when they’re in the air and when they settle onto solar panels. In the first two weeks of September, soot and smoke caused solar-powered electricity generation to fall 30 percent compared to the July average, according to the California…
