Lower Valley Energy Recovers From Regional Power Outage
Afton, WYOMING (July 20, 2016) – Due to a capacitor failure at a main Bonneville Power Administration (BPA) substation in Goshen, Idaho, Lower Valley Energy experienced a system-wide power outage yesterday at approximately 5pm. The outage also affected Fall River Rural Electric, which serves Victor and Driggs, Idaho – and a large part of southeast Idaho.
Instead of waiting for grid power to come back online, Lower Valley Energy coordinated with Palisades Dam operators to bring generation on to critical loads. The issue at Goshen was identified and repaired by 7pm, at which point the region’s power was brought on areas at a time (to avoid overloading the system). The entire system was restored at approximately 8pm with a few small, sporadic outages occurring due to blown fuses.
A second outage occurred at approximately 1 am this morning, affecting a large portion of the Lower Valley Energy service territory. The rerouted Bonneville Power Administration path experienced a failure, causing the outage. The system was restored by 2:24am.
Lower Valley Energy has been working with Bonneville Power Administration for 13 years to develop a new transmission path from Soda Springs, tapping in to Lower Valley Energy’s southern transmission system. The line should be finished by the end of 2017. Had this line been in place, the regional outage stemming from Goshen would have been minimized or eliminated.
While outages like these are unfortunate and few, Lower Valley Energy’s goal is to keep your power on at all times. Lower Valley Energy apologizes for any inconveniences caused and is working hard to prevent this in the future. Lower Valley Energy also appreciates members’ patience and cooperation during outages.
