The Yosemite Rim Fire has threatened to disrupt the power supply to San Francisco, just 150 miles to the west. Power continues to flow to customers, officials stressed, but a rise in wildlfires could post a broader threat to energy infrastructure.

No power disruptions have been reported, but the fire's creep toward the Hetch Hetchy power stations drove Gov. Jerry Brown to declare a state of emergency for the area of the fire and San Francisco, just 150 miles west.
The threat to energy infrastructure comes during a peak period for electricity demand in a state squeezed for capacity. In June, the troubled San Onofre Nuclear Generating Station in southern California was closed permanently. The current 125,000-acre wildfire in northern California, which has burned for 10 days and is 15 percent contained, is adding new stress on the state's energy distribution.
Power continues to flow to customers uninterrupted, officials stressed, and the Hetch Hetchy hydroelectric power stations in the fire's path do not make up core capacity.
