Council demand forecast (draft Ninth Power Plan)

The Northwest Power and Conservation Council's frozen-efficiency demand forecast for the draft Ninth Power Plan, from its 28 public area workbooks as published: annual energy in average megawatts (the Council writes aMW; the dictionary unit here is MWa, the year's megawatt-hours divided by the hours in the year) and the annual single-hour peak in MW, for 2027 through 2046, under each of five future pathways and each of three climate-model weather patterns, with the total load broken into its residential, commercial and industrial, incremental data-centre, electric-vehicle and hydrogen components. Frozen efficiency means equipment efficiency is held fixed so the Council's resource model can choose cost-effective efficiency afterwards: it is a planning input, not a sales forecast, not an observation of load and not a utility integrated resource plan expectation, and it is never merged with one. Futures and climate models are separate dimensions and are never averaged, summed or collapsed together; energy in MWa is never added to a peak in MW. Areas are the Council's own labels, not the atlas frame and not service territories, and NPCC is the Council's own whole-region aggregate, never a sum of the thirteen area rows made here. The hydrogen component is null with not_published on the peak series, which has no hydrogen column. The plan is a draft open for public comment. The data-centre and hydrogen workbooks in the same folder are the forecast's inputs, with their own trajectories and zones, and are described in their own dataset, council-demand-inputs; the folder's README is the citation for the units.

Measures

ColumnUnitWhat it measures
valueMWaAnnual energy the Council forecasts for the area, future pathway, climate model and year, in average megawatts: "the total energy load in megawatt-hours divided by the number of hours in the year" (DemandForecast_README.xlsx Glossary!D3). The component total is the Council's own Total_Load column, never a sum of the components made here; it can differ from them by a unit or two of rounding and is not corrected.
valueMWThe single hour of highest load the Council forecasts for the area, future pathway, climate model and year, "reported in single hour MW units" (DemandForecast_README.xlsx Glossary!D3), with the hour itself kept as the workbook prints it in Pacific wall clock with its PST or PDT label. A peak in MW is never added to energy in MWa. The peak workbooks carry no hydrogen column.

What is missing, and why

  • Listed without a reported value · annual energyRows with no value for this measure; published as null, never zero
    0 values
  • Listed without a reported value · annual peakRows with no value for this measure; published as null, never zero
    0 values
  • Not applicable · annual peakRows where NOT (metric = 'annual_peak' AND component = 'hydrogen_production') is false and that carry no value; the measure does not apply to them
    4,200 values
  • not_computedForecast years after 2046. The README describes the forecast as covering 2027 to 2049; the published area workbooks carry 2027 to 2046 and the atlas publishes what the workbooks carry, never an extrapolation.
    Not computedthe acquired workbooks end at 2046

How often it changes

Checked 2026-09-22
Publisher
The Northwest Power Act requires the Council to produce a power plan at least every five years, and the Council posts the supporting demand workbooks to the plan's public folder as the forecast is developed. The Council states no schedule for the workbooks themselves; the README sheet dates itself "Last updated August 08, 2025 / Initial upload June 30, 2025".www.nwcouncil.org/energy/ninthpowerplan/technical-elements/ ↗nwcouncil.box.com/v/ninthplandemndfcastworkbooks ↗
Delay
The plan these workbooks support is a draft: Council document 2026-3, cover date August 12, 2026, published August 13, 2026 and open for public comment through October 16, 2026. A final plan will supersede it, and filename dates such as "final 03.16.2025" are the publisher's labels on individual files, not the plan's status.www.nwcouncil.org/reports/ninthplan/ ↗www.nwcouncil.org/energy/ninthpowerplan/ ↗
This atlas
Each workbook is pinned by its SHA-256 in the source registry: a changed byte fails acquisition rather than becoming a new edition silently, so the table changes only when a pin is reviewed and moved. No timed refresh.www.nwcouncil.org/energy/ninthpowerplan/technical-elements/ ↗
