Severe weather conditions during winter impact the power grid’s transmission and distribution infrastructure, disrupting power delivery to consumers. Idaho Falls Power (IFP) relies on the surrounding transmission system to supply 75% of the town’s demand for electricity. The connection between the transmission system and IFP offers limited redundancy, making IFP vulnerable to events and vandalism that impact this connection. Moreover, no advanced measurement devices are currently used to monitor the IFP grid. Small “run-of-the-river” hydropower plants connected to the IFP grid can serve about 25% of the total load demand, but if a disconnection occurs, they cannot operate. Thus, the impacts from transmission-level events on reliability are very high.
