The Pacific Northwest has entered a new era of energy demand.

“Energy demand isn’t waiting for our planning processes to catch up.”

That statement captures a defining challenge for the Pacific Northwest. Advanced manufacturing, high-tech facilities, electrification and economic growth are reshaping the region’s energy needs. Meeting those needs requires timely investment in the resources and infrastructure that deliver energy to customers. For families, employers and communities, the stakes are practical: dependable service, manageable bills and confidence that energy will be available when it matters most.

The Northwest Power and Conservation Council’s initial forecast projects annual electricity demand growth of 1.8–3.1% and annual peak demand growth of 1.9–3% from 2027 through 2046. Across Washington, Oregon, Idaho and western Montana, average electricity demand could rise from approximately 22,000 average megawatts to between 31,000 and 44,000 by 2046. The upper end represents roughly twice today’s consumption. These figures describe electricity demand, one component of the region’s broader energy needs.

The projected growth establishes a clear planning challenge. High-tech facilities are a major near-term driver, while electrification of vehicles and buildings adds longer-term requirements. Planning must account for how much electricity customers consume, where they need it and when that demand occurs.

NWGA’s 2026 Pacific Northwest Gas Market Outlook shows that natural gas demand is also evolving. Its expected case projects 12.2% cumulative growth over the ten-year forecast period, covering British Columbia, Idaho, Oregon and Washington. Growth varies considerably by sector and location: residential and commercial demand in Washington and Oregon remains essentially flat, while Idaho shows growth.  The industrial growth is driven largely by the anticipated Woodfibre LNG facility in BC. Gas demand for electricity generation returns to modest projected growth after declines forecast in the previous two Outlooks. These differences matter because infrastructure planning must reflect the location, timing and purpose of new demand.

Annual totals, however, tell only part of the story. Energy systems must deliver during prolonged periods of extreme weather, when heating requirements climb and generating conditions may deteriorate. The joint gas-electric adequacy document provides a concrete example: during the January 2024 cold snap, the Northwest relied on nearly 5,000 megawatts of electricity imports on average to maintain reliability. Serving customers also required emergency operations, conservation requests and close coordination between gas and electricity providers. That experience demonstrates why dependable delivery deserves attention alongside total energy supply.

E3’s June 2026 resource adequacy presentation reinforces the urgency. Its modeling identifies a gap of 9 gigawatts of effective capacity by 2030, growing to 14–18 gigawatts by 2035, driven by accelerating demand and continued resource retirements. Effective capacity measures a resource’s contribution to reliability, rather than simply its rated generating capacity. The study highlights extended cold weather during low-hydropower years as a critical challenge, with simulated shortfalls lasting multiple days. These are modeled risks under study assumptions, giving planners a basis for preventive action.

Natural gas and electricity planning must advance together. The Outlook reports that average utilization of regional interstate pipelines exceeded 90% during December through February over the preceding five years. Existing infrastructure therefore has limited flexibility during stressful conditions. As electric generators rely on gas during critical hours, planners must evaluate fuel delivery, storage availability and competing heating requirements together. A generating facility’s reliability contribution depends on its ability to obtain fuel when customers need its output.

The response should combine energy efficiency, flexible demand, renewable generation, storage, dependable capacity and delivery infrastructure. E3’s analysis identifies a diverse portfolio as a pathway to substantial emissions reductions while maintaining reliability and affordability. Turning that pathway into operating resources requires coordinated forecasts, workable permitting schedules, timely transmission development and realistic construction assumptions. Policymakers should also recognize the continuing contribution of direct natural gas service when evaluating changes to winter electricity needs.

For NWGA, Reality 7 calls for decisions that connect ambition with implementation. Every forecast should lead to an assessment of what must be built, upgraded, conserved or coordinated—and by when. Customers deserve an energy transition that supports economic opportunity while protecting reliability and affordability. Demand is growing now. Our planning, infrastructure and shared commitment to delivering energy must keep pace.
