- Ratings
- The cited records do not disclose a current operating status, normal or emergency thermal rating, or verified circuit count. The Pacific DC Intertie’s voltage and transfer rating apply to a different transmission corridor.
- Transmission system
- BPA’s July 2025 rate study places its Big Eddy–Celilo facilities in the Southern Intertie segment, which carries power between the Pacific Northwest and California. It lists facilities named Big Eddy–Celilo No. 1 through No. 4. Individual circuit numbers are not identified in the HIFLD route.
