ANN ARBOR, February 11, 2014: Power outage maps for those utility companies that provide it are listed here by state, alphabetically. As of February 11, 2014, 45 of 50 states have something here.
The list is known to be incomplete, but the list from Wikipedia (outage management system) is also incomplete. To be overly comprehensive, if there are screen captures that I can gather, I will; they will not be current when you look at them, but I will time and date stamp them as best I can.
Wherever possible, I'm also capturing service area or service territory maps, mobile device apps, high capacity transmission interconnection maps, media contact information, regulatory agencies, and regional coordinating bodies.
Power outage related products
You might want to have an battery backed emergency sump pump or a water powered backup sump pump, plus a basement water sensor and alarm. Be aware of approaching weather with a weather alert radio and a hand crank emergency radio. Or spring for a 27 kilowatt whole house generator that runs on propane or natural gas.
