Evidence and method

modeled · directThe resources the Council's model selects under each sensitivity of its draft Ninth Plan scenario analysis: a planning scenario, not the plan's recommended resource strategy, not a utility's plan and not a forecast of what will be built. Each sensitivity's portfolio is optimized over the same sampled futures (demand, gas prices, hydro, wind and solar; Appendix K, all-appendices PDF page 480), so there is no future pathway or climate model in the workbook. Units: the Data sheet heads its value column 'Nameplate Cap. (MW)' ('Size in nameplate MW', Glossary!D10), but the plan draws conservation (resource type EE) in average megawatts (Figure 4-1 axis 'Nameplate MW / Conservation aMW', plan PDF page 92; Figure N-6 'average MW', all-appendices PDF page 559), and the EE rows summed over zones reproduce Figure N-6's bars; EE is recorded here in MWa and every other type in MW nameplate. A snapshot lists what the model holds in that simulated year, including resources built in an earlier year; snapshots are never added together, sensitivities are never averaged, and conservation in MWa is never added to capacity in MW. Zones are the Council's own model zones (Glossary!D7: supply-side resources may be built in one zone for another zone's demand), not the atlas frame or a service territory. The plan is draft 2026-3, open for comment through October 16, 2026.

The plan this workbook supports 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. The workbook is the model's selection under each sensitivity; the plan's recommended resource strategy for 2027 to 2032 is set out in its Chapter 4.www.nwcouncil.org/reports/ninthplan/ ↗www.nwcouncil.org/energy/ninthpowerplan/ ↗

The 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 the pin is reviewed and moved. No timed refresh.www.nwcouncil.org/energy/ninthpowerplan/technical-elements/ ↗
