Pacific Northwest energy plan proposes massive grid expansion by 2032

The Northwest Power and Conservation Council has released a draft of its Ninth Power Plan, outlining a strategy to meet surging electricity demand in the Pacific Northwest by 2032. The plan calls for a massive expansion of the regional power system to accommodate growth driven by data centers, vehicle electrification, and population increases.

To achieve this, the region—comprising Oregon, Washington, Idaho, and Montana—will need to add over 11,000 megawatts (MW) of new generation and more than 5,000 MW of storage. The proposed resource portfolio includes 9,000 MW of renewables and 2,100 MW of natural gas. The plan also emphasizes energy efficiency, targeting 1,060 average-megawatts (aMW) across the region.

The estimated fixed cost for this portfolio is $2.3 billion. Jennifer Light, Director of Power Planning, stated that no single resource can meet future needs alone, necessitating a diverse mix to balance economics, reliability, and adequacy. The council will hold public hearings in September and October across the four states, with public comment open until October 16.
