Puget Sound Energy - Energy Efficiency Custom Retrofit Grant Program

PSE's Custom Retrofit Grants can cover up to 70% of equipment and installation costs for energy-efficient upgrades like boiler replacements, heat recovery systems, and VFDs that don't fit their standard programs. You must be a PSE business customer and get pre-approval before installation by contacting PSE early with your project details—submit an online application with cost proposals, drawings, and energy-savings calculations.

This program allows you to help customers access substantial incentives ($0.45 per annual kWh saved and $8 per annual therm saved, up to 70% of project costs) for custom efficiency measures like process boilers, chillers, and compressed air upgrades. PSE requires customer pre-approval and documented energy savings before installation, so engage with PSE early in project planning to confirm eligibility and maximize grant value for your clients.

The Custom Retrofit Grants program incentivizes non-standard commercial and industrial efficiency projects (schools, manufacturing, government facilities) through cost-effectiveness review and pre-approval, with electric incentives at $0.45/annual kWh and gas at $8/annual therm, capping at 70% of eligible costs. PSE engineers manage eligibility assessment and customer support, while funding availability is subject to program capacity; separate O&M grants (up to 100% coverage) support tune-ups and optimization with $0.10/kWh and $2/therm rates.
