Location: Hermiston, OR
Lines east of Hermiston, from UEC’s Columbia Substation on South Edwards Road to the Foster West Substation on Hwy. 37, were replaced. These improvements support irrigation load in the region, providing additional capacity and allowing irrigators in the region to create more irrigated agriculture circles.
Anticipated Construction Schedule
Start Date: May 2021
Completion Date: March 2026
Why Rebuild The Existing Transmission Line?
The segments improved have served our membership for many years. These lines predominately serve residential and agricultural loads, which continue to experience growth. In order to continue to provide reliable, cost effective power while supporting this growth long into the future, it was necessary to rebuild these line segments.
UEC’s Commitment to Our Membership
Transmission lines are high-voltage lines that carry electricity from generation plants to substations, or from substation to substation.
By replacing the existing line, UEC has improved the reliability and resiliency of the transmission system in the Hermiston area. These improvements ensure that UEC can provide reliable power long into the future.
Benefits and Value Carefully Considered
Most of the work was conducted without the need to interrupt power. In some instances, an outage of one hour or more were needed to safely transfer power to the new lines. Affected members were notified in advance of a planned outage.
