SMUD Launches Natural Refrigerant Incentive Program

The Sacramento Municipal Utility District (SMUD) has announced the launch of a new pilot program that will provide incentives for direct greenhouse gas (GHG) emission reduction. The program will provide incentives for both energy savings and GHG emissions reduction.

The program is open to SMUD's commercial customers that install new natural refrigerant system or retrofit a system from a high-GWP refrigerant to a natural refrigerant. New systems can include distributed systems, transcritical and cascade, stand-alone systems or self-contained units. 

Incentive levels for GHG emissions reduction are calculated separately from energy savings. Energy savings are paid under SMUD's Custom Incentive program for both kW and kWh reduced. GHG emissions reductions are paid per metric ton of CO2-equivalent emissions reduction.

A bonus incentive is available for projects implemented by small businesses located in disadvantage communities. The bonus equates to 25% of the GHG emission reduction incentive.

The total combined incentive is capped at $250,000 or 50% of the project cost, whichever is less.

The GHG emission reduction calculation is based on the refrigerant GWP, charge size and annual leak rate. For retrofits, GHG reduction is calculated based on the difference between the existing and forecasted performance of the system. New systems will use a pre-defined baseline that assumes a default refrigerant, change and leak rate. The following equation will be applied:

Participants must also agree to allow SMUD access to collect energy consumption data for a minimum of a three-year period. Sub-metering equipment will be installed on refrigeration and electrical systems to monitor energy use.

According to SMUD, in addition to the energy savings and GHG emissions reduction, one of the primary purposes of the pilot is to conduct research that will contribute to the growing body of literature that supports refrigerant policy and practice.

NASRC Receives Award from the National Small Business Environmental Assistance Program

NASRC was recognized by the National Steering Committee (NSC) of Small Business Environmental Assistance Programs (SBEAPs), and Small Business Ombudsmen (SBO) for its leadership nationwide in the areas of compliance assistance, sustainability, advocacy and collaboration. The award was presented to NASRC at the NSC meeting May 17, 2017, in Denver, Colorado.

NASRC was awarded for its work in accelerating the transition from fluorinated gases — F-gases, including hydrofluorocarbons — to low-global warming potential, or GWP, refrigeration equipment and technologies. F-gases are the fastest-growing source of greenhouse gas emissions in California and globally.

NASRC is being recognized for establishing best practices for natural refrigerants such as low-charge hydrocarbon and ammonia, and carbon dioxide; providing educational resources to service providers, end users and manufacturers of natural refrigerants; and supporting certification organizations and government agencies to help streamline approval processes for natural refrigerant equipment and technologies.

NASRC’s collaboration with utilities such as the Sacramento Municipal Utility District and end users of refrigeration equipment has been instrumental in developing utility incentives that include an extra bonus for small businesses to encourage the conversion to natural refrigerant gases and energy efficiency equipment. Because refrigerant equipment has a high cost of ownership, it is imperative small businesses have incentives. This award underscores NASRC’s leadership in the industry, not only shining the spotlight on sustainable practices, but also for showcasing low-GWP alternatives and the importance of business/small business incentives, and the role of small businesses in this industry.

NASRC board members Clay Rohrer, Tristam Coffin, Keilly Witman, Aaron Daly, Todd Washburn, Bryan Beitler, Peter Narreau and Peter Dee pose with the award of the most recent board meeting.

“It is a great honor to be selected for this award. NASRC has accomplished a tremendous amount given we have only been in existence for less than two years. There is still much work to be done to remove the barriers of adopting natural refrigerants, especially for small businesses that need financial incentives to support the transition. This award not only highlights the important role of natural refrigerants in significantly reducing greenhouse gas emissions but the collaboration necessary in order achieve our vision of a more sustainable future,” said Danielle Wright, executive director of NASRC.

NASRC member Source Refrigeration has also collaborated with the California Air Resources Board’s SBEAP in the production of a leak inspection video and fact sheet. NASRC has analyzed whether financial incentives could help promote more immediate transition for small- and medium-sized markets. In addition to this incentive program, it is helping to establish best practices for natural refrigerants, providing education resources and online training opportunities.  

The SBEAP/SBO NSC Awards are the premier environmental awards for recognizing outstanding environmental performance, programs and individuals. The awards honor and recognize small businesses, individuals, trade associations and others who have made significant contributions to protecting the environment. 

About the Small Business Environmental Assistance Programs (SBEAPs)

The Small Business Environmental Assistance Programs were created under Section 507 of the Clean Air Act Amendments of 1990.  For more than 25 years, the SBEAPs have provided extensive, hands-on technical assistance to small businesses across the country to help them understand and comply with complex environmental regulations. SBEAPs recently launched a new website,, which is a resource for program participants and small businesses. Find state-specific contacts at

Danfoss CO2 Mobile Unit to Offer Hands-On Training and Live Demo

Danfoss will deploy its CO2 Mobile Training Unit across the Western US this Summer making stops in Anaheim, California and Boise, Idaho. The CO2 Mobile Training Unit will be hosted by Source Refrigeration in Anaheim, June 19-29th, and by DC Engineering in Boise, July 11-19th. Both locations will feature two-day hands-on training sessions of CO2 equipment, components and interactive learning modules.

The two-day hands-on trainings will be in-depth technical training targeted for retailers, contractors and service technicians featuring interactive learning modules ranging from simple booster systems to more complex parallel compression. The CO2 Mobile Training Unit is helping to meet the growing demand for system building, installers and service technicians that are familiar with CO2 refrigeration systems.

“CO2 is continuing to gain traction in commercial refrigeration as food retailers look for ways to comply with legislation that phases out higher-GWP refrigerants,” explained Peter Dee, food retail sales and services director. “Danfoss has already been involved in more than 10,000 installations of CO2refrigeration systems worldwide.”

NASRC will partner with Source Refrigeration in Anaheim, and DC Engineering and CTA in Boise, to offer Natural Refrigerant Seminars and Live Demos of the system. These events will be half-day sessions focused on providing a broader overview of natural refrigerants, including benefits and challenges, as well as case studies.

The CO2 Mobile Training Unit will also be on display at the ATMOsphere America Conference in San Diego, California, June 5-7.
