US, Wisconsin: Fires at two transmission substations in Madison, Wisconsin knocked out power to thousands of customers sending dual plumes of thick, black smoke into the air and shutting down government buildings, courtrooms and businesses, and leading the governor to declare a state of emergency.
No injuries were reported as a result of the 7:40 a.m. explosion and fire at the Madison Gas and Electric main power center a few blocks from the state Capitol, which was among the buildings that were forced to close. A second fire at a substation near the University of Wisconsin-Madison, a couple of miles to the west, prompted the evacuation of nearby buildings. No injuries were reported as a result of that blast, either.
At its peak, more than 13,000 people were without power.
