Custom Retrofit Grants

Get PSE incentives for retrofits on your commercial facility

PSE offers incentives on cost-effective energy efficiency measures that have quantifiable costs and energy savings. Common custom measures include boiler upgrades, the installation of variable frequency drives (VFDs) on fans or pumps, HVAC equipment replacement, building envelope improvements, high-efficiency chillers, and air compressor upgrades. Other common measures such as Lighting, HVAC Controls, and Advanced Rooftop Controls have their own programs. All other custom measures may be incentivized through this program.
