Idaho Falls Power

Building for your future


North Loop Project

Idaho Falls Power continues to move ahead with the North 161kV Transmission Project to secure reliable delivery of electric service to its customers. The project calls for the construction of a transmission line on the north side of Idaho Falls that will link the City’s two main substations and complete the backbone infrastructure as originally planned.


Idaho Falls is pushing the capacity limits of its sub-transmission system throughout the core of the City. Continued growth has led to peak demands that have routinely exceeded capacity on the line for the last five years, and additional growth planned for the near future will exceed the line’s capacity.


The North 161 kV Transmission Loop will alleviate those concerns. The transmission line will help IFP meet the demand on the north side of the City, and it will provide the utility with the ability to redirect power loads during periods of peak usage. Extending this service capacity to the north will help IFP reliably deliver power to new and existing customers.
“Completing this project is critical to our ability to continue to provide safe, reliable, high quality electric service to our customers, while keeping our costs among the lowest in the region,” said Jackie Flowers, Idaho Falls Power General Manager.


IFP has been planning and laying the groundwork for this project the past four decades. The need was first identified in a study conducted in 1972. Idaho Falls has grown significantly since then, as has the demand for electricity. While the study lead to the construction of a portion of the project (the south loop), construction of the complete transmission loop as initially planned was not completed.  A 2007 transmission planning study update reaffirmed the need for the complete project envisioned in 1972.


The project will be funded using capital improvement monies that have been saved in preparation — thus no rate impact.  We have received and implemented public input; held public comment periods (although none were required); conducted engineering design and environmental analysis; and held numerous meetings with property owners, stakeholders and various agencies.
