Puget Sound Energy - Multi-Family Efficiency New Construction Grant Program

PSE offers grants for new multifamily buildings (5+ attached units) based on energy savings, paying $0.45/kWh or $8/therm for standard projects, with 50% higher rates for affordable housing that meets state low-income requirements. Contact PSE early in your design phase through their application or Willdan's team at 206-216-3405 to get pre-approved and receive a customized analysis of your building's energy-saving potential.

Your multifamily projects in PSE's service territory qualify for performance-based grants if the building has at least 5 attached units and you engage PSE before construction begins; the program covers prescriptive equipment and custom measures, with incentives tied to verified energy savings and 50% bonus incentives available for affordable housing projects meeting state low-income thresholds. Pre-approval from PSE is required before installing any efficiency measures, and projects move through enrollment, preliminary analysis, design bundle selection, construction verification, and final incentive issuance.

This whole-building performance program pays incentives at $0.45/kWh ($8/therm) for standard projects and $0.68/kWh ($12/therm) for affordable housing, with the bonus multiplier applying to all efficiency measures including lighting. PSE targets multifamily new construction in its electric and gas service areas, requires pre-approval and early design-phase engagement, and verifies final construction compliance; eligible affordable housing projects must meet Washington State Housing Finance Commission low-income requirements (at least 40% of units at ≤60% AMI, at least 20% at ≤50% AMI, with income averaging allowed).
