A full-scale training exercise simulating a long-term mass power outage in Wisconsin kicks off today at sites around the state. There will be no actual power outages associated with this training exercise. Known as Dark Sky, the exercise runs May 15-17 in Brown, Calumet, Dane, Fond du Lac, Milwaukee, Outagamie and Winnebago Counties and will test the abilities of private utilities, law enforcement, first responders and the National Guard to respond to the scenario as well as its second and third order effects.
The public should not be concerned if they notice an increased emergency responder presence, military personnel, vehicles and equipment, or non-military unmanned aerial vehicles operating in those communities during the exercise. The exercise includes an Alliant Energy facility in Fond du Lac County, which will serve as one of the National Guard training sites.
The goal of the exercise is to increase understanding of the coordination, policies, and procedures required to conduct a joint inter-agency response to cyber and physical threats to critical infrastructure in Wisconsin.
