Plant and service-territory candidates

Which service-territory polygons contain each published plant's reported coordinate, from four state-hosted layers: Washington Ecology's electric utility service areas, Oregon ODOE's (electric areas only), Idaho's electricity providers and Montana's rural electric cooperatives. A row is a candidate from point-in-polygon containment, never a service relationship or a supplier: the layers are unofficial and approximate, overlaps and gaps are kept, a plant can sit inside several polygons or none, Montana's layer covers cooperatives only, and service questions go to the utility.

Measures

ColumnUnitWhat it measures
territory_entity_idcountOne row per published plant and polygon whose boundary contains the plant's reported coordinate. The table carries no quantity; a row is a candidate, never a service relationship.

Population

What the rows are counted against
  • Publishedpublished plants of the inventory year; those with a source-reported coordinate are tested against every polygon a layer keeps, and overlaps are kept, so a plant may have several candidates

What is missing, and why

  • Listed without a reported value · candidateRows with no value for this measure; published as null, never zero
    0 candidates
  • No row in the sourcePublished plants with a reported coordinate in a state a layer covers that fall inside no polygon of any layer: the layers are unofficial and approximate with their gaps kept, and Montana's covers cooperatives only. No service relationship is implied either way
    28 plants
  • Not applicablePublished plants with a reported coordinate outside every layer's state and inside no polygon: no territory layer covers their state
    16 plants
  • Not derivedPublished plants without a source-reported coordinate: containment cannot be tested, so they have no candidate, which is not a claim of none
    4 plants
  • Outside the atlas framePlants in the inventory that the atlas does not publish: outside the frame authorities and the core states, never tested
    15,424 plants
  • Not applicablePolygons a layer's declared filter leaves out, such as natural-gas service areas in a combined gas and electric layer: never tested against plants
    3 polygons

None of the four layers states a fixed schedule. Ecology's layer metadata gives its maintenance frequency as needed; ODOE's item says it regularly updates utility service areas and keeps an update log; the Idaho and Montana items state no update frequency.gis.ecology.wa.gov/serverext/rest/services/CPR/CPR/MapServer/0/metadata ↗www.arcgis.com/sharing/rest/content/items/2102826e218c4d36a24583613df76f0c ↗www.arcgis.com/sharing/rest/content/items/88b876b91ca14dc6b94d7794522c7373 ↗www.arcgis.com/sharing/rest/content/items/ba0648df3ce94af78865f10d0c583451 ↗

The layers are boundaries without a reporting period. On the checked date Ecology's metadata dated its publication June 3, 2024, and the Idaho, Oregon and Montana service layers were last edited October 11, 2024, August 25, 2025 and February 19, 2026.
