The Cool Switch Low Impact Refrigerant Program’s goal is to incentivize the use of refrigerants with lower Global Warming Potential impacts.
Hydrofluorocarbons (HFCs) are a common type of chemical refrigerant in the U.S. HFCs were developed as alternatives to chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which damage the earth’s ozone layer. Though safer for the ozone layer, HFCs still contribute to global warming. Other types of refrigerants, such as “natural refrigerants,” or a new class of refrigerants called hydrofluoroolefins (HFOs) have limited climate impacts and can provide an alternative to HFCs.
Cool Switch offers participants grants for replacing existing refrigerants with low GWP refrigerants or installing new systems that use low GWP refrigerants.
All Delaware non-residential consumers that use at least 50 lbs of refrigerant are eligible to participate in Cool Switch.
Applicants should keep abreast of regulations currently under development that may affect the use of certain HFCs in Delaware.
Installed refrigerants must have a GWP less than 1,500. Examples include: R-449A, R-448A, Ammonia, and Carbon Dioxide.
Avoided tons of CO2-equivalent emissions associated with a Cool Switch Project will be calculated using the following inputs:
Incentives for all pathways will be paid at a rate of $25 per ton of avoided CO2 equivalent emissions up to the limits described below:
Retrofit System Incentive Limit:
New System Incentive Limits:
All grants require pre-approval prior to purchasing any services, equipment or refrigerants. Participants must submit an application form to DNREC. Information required includes:

A pre-installation site visit may be required.
After project completion, participants submit itemized invoices for all install equipment and refrigerants. DNREC will conduct a final review and may require a post-installation site visit. Once the project passes final review, the grant is disbursed.
DNREC’s Energy Efficiency Investment Fund (EEIF) can be used to supplement a Cool Switch grant. Cool Switch program participants can apply for and receive EEIF grants based on the energy savings associated with Cool Switch projects.

The State Energy Program Revolving Loan Fund can be used to supplement an EEIF grant project or as a stand-alone loan for installation of energy efficiency measures. Information on the Revolving Loan Fund is available on the EEIF web page. Applicants must have an energy audit that includes a detailed description and documented energy savings of the proposed project. Applicants can be from non-residential, commercial, or industrial sectors.
