Commercial Horticultural Incentives
Earn incentives for upgrading your grow lights and dehumidifiers
Whether you’re growing cannabis, lettuce or some other crop, our Commercial Horticulture program offers incentives for installing energy-efficient equipment.
What you get
Lighting incentive amounts vary depending on whether you’re replacing existing lights (retrofit) or installing lights in a new area (new construction). Dehumidifiers are incentivized at a different rate than lighting. Current incentive rates are listed below.
Retrofit - Lighting
New Construction - Lighting
Up to $0.20 per annual kWh saved
Up to 100% of the incremental cost difference between a WA Energy Code baseline and the proposed LEDsRetrofit - Dehumidifiers
New Construction - Dehumidifiers
Up to $0.45 per annual kWh savedUp to 100% of the incremental cost difference between a WA Energy Code baseline and the proposed dehumidifier unitsHow you qualify
To be eligible for the Commercial Horticultural program:
- You must be a PSE commercial or industrial electric customer.
- You must be growing indoor or greenhouse plant canopy.
- If pursuing a lighting incentive, you must install LED fixtures that are listed on the Design Lights Consortium Horticultural Qualified Products List.
- You must be pre-approved by PSE prior to the installation of any energy-efficiency measure.
How you apply
To get pre-approved for a Commercial Horticultural incentive:
- Complete the online custom retrofit grant application.
- For lighting projects, please include the following additional information: PSE horticultural lighting calculator, manufacturer's specification sheets for the proposed LED grow lights, and a PDF printout of the LED product listing from the Design Lights Consortium.
- For dehumidifier projects, please include the following additional information: PSE horticultural dehumidification calculator, manufacturer’s specifications sheets for the proposed equipment.

Additional information
Do you have an energy efficiency upgrade in mind that is not lighting or dehumidifiers? Consider applying for an incentive through our Custom Retrofit Grants program or our Commercial New Construction program.
How your incentive is calculated
For retrofit projects, PSE will compare the existing system efficiency to the proposed system efficiency. Existing lighting or dehumidification systems must be confirmed by PSE before the work begins.
For lighting projects, savings will be calculated using the Photosynthetic Photon Efficacy of the proposed LEDs. This means you’re likely to receive a higher incentive when installing an LED fixture with a higher umol/J rating. The same is true for a dehumidifier’s L/kWh energy factor.
