Why Rebuild The Existing Substation?
UEC needs to invest in new infrastructure to meet the increased need of the rapidly growing region. The substation was completely rebuilt for improved efficiency and resiliency for members in the area. By rebuilding the infrastructure, capacity was increased significantly to service members in the area.
UEC’s Commitment to Our Membership
Substations are critical links in the electric distribution system, containing utility circuit protection, voltage regulation, and equipment that steps down higher voltage to lower voltage. Before reaching homes, businesses or farms, power is routed through our transmission system to a substation, where it is changed to a lower voltage that can be managed, utilized and delivered to members.
Benefits and Value Carefully Considered
If the Umatilla Substation was not rebuilt, we would have continued to rely on aging and antiquated infrastructure that was experiencing capacity constraints and nearing the end of its useful life – increasing the risk of equipment failure and member power outages over time. Our mission is to provide reliable power to our members. UEC will continue to address the area’s growing energy needs to ensure we can continue to provide reliable power for years to come.
