​Central Oregon Load Interconnection Capability
​To support the broader economic development goals of the region, BPA is seeking to better understand local economic development priorities and inform customer and stakeholder decisions by pro-actively providing information about BPA’s local load-service capabilities.

The Central Oregon area includes the community of Madras to the North, the city of Redmond to the west, the city of Prineville to the east and the cities of Bend and La Pine and community of Sun River to the south. It includes Crook, Deschutes, Jefferson, Lake, Klamath, and Burns counties in Oregon.
Utilities in the Central Oregon Load Area include
  • ​Central Electric Cooperative
  • Midstate Electric Cooperative
  • PacifiCorp
  • Portland General Electric
​Recent BPA projects completed in the area
  • ​Ponderosa 500/230 kV Transformer #2 Addition
  • La Pine Capacitor and Reactor Addition
  • Slatt-Buckley Series Capacitor Addition
  • Bakeoven Series Capacitor Optimization

The upgrades at Slatt substation on the Slatt-Buckley 500 kV line and series capacitor optimization at Bakeoven Compensation Station on the John Day-Grizzly #1 and #2 lines increase the main grid capability in the Central Oregon Redmond Import area by 315 MW. These upgrades are in addition to previous infrastructure investments BPA has made over the last 10 years to increase the main grid capability and enable load service in Central Oregon, which has collectively increased the Redmond Import area capacity from 560 MW to 1145 MW.
