Project Need
Growth in the Ontario, Ore., area has resulted in increased electrical demand on the Nyssa-Vale-Ontario power transmission system serving the area. This reduces the options available to deal with maintenance and repair issues on the system. 

In order to continue to provide reliable electric service to Ontario, Nyssa, and Vale area customers and to meet existing and future electrical capacity needs, Idaho Power plans to build a new transmission line in 2008 from the Ontario Substation and tie in to the line between Nyssa and Vale at a place that will be called Ontario Junction. the 16-mile powerline will be built to 138,000-volt standards, but will be energized at 69,000 volts.

As electrical loads in the area grow, the Ontario Junction site will be developed into a substation called Sage Substation. The location of the junction/station has been selected to provide the greatest reliability at the lowest cost to customers in the Ontario, Nyssa, and Vale area.

Conditional Use
A Conditional Use permit is required for this new junction point/station. Pending approval, construction will begin in the spring of 2008.

Station Details
The proposed Ontario Junction/Sage Station site is located about halfway between Nyssa and Vale, Ore. The substation site will be approximately two acres. The station’s purpose is to provide alternate means of supplying power and increased voltage support to the Ontario, Nyssa, and Vale substations.

See Project Schedule for the proposed schedule.
