A severe spring snowstorm in Carbon County, Wyoming, led to a 36 hour power outage in Rawlins after a transmission line crossarm failed. The incident stranded motorists on I-80 and disabled critical infrastructure, including refueling stations for snow plows and emergency communication lines.

A single broken crossarm taking out an entire town for 36 hours is a classic N-1 contingency failure. It shows how fragile these radial feeds are. Do we know if there is any redundancy planned for the Platte and Whiskey Peak corridor, or is this just the way it is?
The real issue here is the lack of resilience in the transmission design. When a single point of failure shuts down emergency services and refueling for road crews, the cost of inaction on grid hardening is higher than the investment. This is a policy failure in utility reliability standards.
The fact that people had to be moved to a community center for heat shows the lack of building envelope efficiency in these areas. If these structures had better insulation or independent backup heat, the emergency response wouldn't be so strained during a simple power cut.
