Large-load connection requests in this county
Requests to connect large new demand — data centres, industry, electrification — as distinct from generation. 3 recorded here.
| Request | Capacity | Status | Queue | Stated end use |
|---|---|---|---|---|
| Chemawa-Waconda 115 kV Line Project | 0 MW | active | BPA | not stated |
| Conser 115kV | 0 MW | active | BPA | not stated |
| Lyons Loop | 0 MW | active | BPA | not stated |
494 of the 545 large-load requests we hold state no end use at all, so most cannot be attributed to any industry. Where this table says “not stated”, that is the filing’s own silence, not our omission.
