Supporters back heat-pump replacement rules while utilities and builders warn on costs and grid implications

Several speakers at the Aug. 7 hearing urged the SBCC to adopt proposals that encourage replacing failing air conditioners and other equipment with heat pumps at time of failure. Kimberly Loewen of Elevate said proposal 209 and related items would boost heat-pump adoption "at the most practical and cost effective times" and improve resilience during heat and wildfire smoke events.

Supporters included climate and public-health groups that said heat pumps reduce emissions and improve indoor air quality; David Camp of 350 Spokane and Colleen Anderson of 350 Yakima urged the council to step up electrification and resilience measures. Technical witnesses urged preserving ERI flexibility while correcting modeling errors.

Opponents — including Cascade Natural Gas, Northwest Natural, homebuilders and many contractors — warned that some provisions (notably electric-readiness mandates and credit penalties for fossil-fuel systems) would raise first costs, complicate retrofit work, and could create grid reliability pressures in regions with constrained distribution infrastructure. "Mandating oversized electrical panels, heavy amp service upgrades, and redundant electrification readiness conduit for gas appliances drives up both equipment and labor costs before homes are even occupied," said Zachary Silikian of Northwest Natural.

Multiple speakers asked the council to fix a discrepancy in the residential U-factor tables (0.056 vs. 0.045), to restore an ERI envelope multiplier that limits trade-offs, and to publish credit tables so stakeholders can meaningfully comment. The Department of Commerce and other agency representatives said the TAG-forwarded package aligns with the state energy strategy and statutory targets.
