BPA transmission lineRegional context
Rock Creek-John Day No 1
About this record
BPA line geometry as published, with the operating voltage in kV as reconciled from the source field; no power flow or capacity.

Operating voltage
500kV
Source & method
BPA field VoltageMeas read as kilovolts: the source declares no unit, but every line whose name states a kV figure carries that figure in the field and values fall on standard classes (validation check lines.voltage_unit_is_kv)
2026-07-07 · reported · derived · valid · final
Unit established by reconciliation: line names that state a kV figure agree with the field for every such line, and values fall on standard transmission classes; the Pacific DC Intertie rows read 1000-1100 (pole-to-pole DC)

Line layer only - Route
- BPA’s published geometry, 22.5 km long, retrieved 2026-09-29 04:56 UTC from the layer as BPA reloaded it 2026-09-26 16:01 UTC.The geometry as retrieved from BPA's layer on this date. BPA reloads the layer weekly and can change a line's geometry at any reload; the reload stamp dates the layer, not this line. Length: Planar length of the published geometry in CONUS Albers (EPSG:5070), within about 1% in the region; BPA publishes no length.
- Voltage
- 500 kVThe layer declares no unit; VoltageMeas is read as kV on the layer-wide reconciliation (validation lines.voltage_unit_is_kv) No BPA document is cited for this line’s voltage.
- Owner
- Bonneville Power Administration ↗ BPA publishes the line in its own layer; no BPA document read here states its ownership. No document read names an operator separately.
- Paths
- No curated path names this line.
Planned work
Rock Creek-John Day 500 kV Line Upgrade ↗BPA’s GERP layer, as published 2026-07-29: GERP 1.0 · Design · expected energization 2030This project is an upgrade of the existing Rock Creek – John Day #1 500-kV line. BPA would rebuild 14 miles of line between the Rock Creek Substation (Goldendale, WA) and John Day Substation (Rufus, OR), including a Columbia River crossing.The layer does not say what the figure covers: the project's other segments and substations, or a group of projects, may share it 109,000,000 USD
Each cost is the figure its document states for the scope it names, never this line’s alone; figures from different documents are not added or reconciled. Dates are BPA’s expectations as each document prints them.
Not published here
ConductorConductor type, size and bundling are not in BPA's public line layer; a planned reconductor names no conductor.
Held by BPAStructure design
BPA publishes structure points by line name in a separate layer with a symbol code it does not define; designs, heights and circuit arrangement are not published. The atlas does not acquire that layer.BPA source ↗RatingsThermal and operating ratings (MVA or amperes) are not in any public BPA layer. A path's transfer capability limits the whole cut and is never this line's rating.
Held by BPAAvailable capacity
BPA calculates available transfer capability per flowgate or path, not per line (ATC Implementation Document); a line has no available-capacity figure of its own.BPA source ↗Outages
BPA posts outage plans and its outage policy on its Outage Coordination site (ATC Implementation Document, section V); outages of this line are not collected here.BPA source ↗Flow
BPA publishes metered flow per path, not per line; a path's flow is never attributable to one of its lines.BPA source ↗In-service date and edit historyThe layer's CreationDate and EditDate are stamped on every feature at each weekly reload: they date the reload, not this line's construction or last change.
Held by BPA
A line beside a plant or project never establishes a connection, available capacity or transmission service.

Informational geometry, name and operating voltage (kV, reconciled). No connectivity, capacity, ownership beyond what BPA states, or flow is asserted.

Proposed line rebuilds and upgrades as BPA published them for its GERP cycle: expected energization year, estimated cost in dollars and status are BPA's planning figures at publication and change with each cycle; the geometry is the existing line the project follows, not a final route.
