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.

Up to $0.20 per annual kWh saved

Up to 70% of the full cost of materials

How 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.
