Your Smart Energy enrollment helps fund projects that reduce, or prevent the release of, greenhouse gas.
Smart Energy Renewable Natural Gas Projects
Currently, for customers with service in Washington, the Smart Energy program purchases RTCs from the Wasatch Resource Recovery Facility in Utah and retires them on participants’ behalf.
Renewable natural gas is produced by capturing emissions from sources like landfills, food and agricultural waste, and wastewater, then using those emissions as a carbon-neutral fuel.
For every dekatherm (10 therms) of renewable natural gas produced and used at qualifying facilities, a renewable thermal certificate (RTC) is created. An RTC represents the environmental attributes of the generation and use of the dekatherm of renewable natural gas, similar to renewable energy certificates for wind and solar electricity generation. RTCs are currently tracked, validated and retired via the Midwest Renewable Energy Tracking System (M-RETS), which ensures the validity and integrity of RTC creation and retirement. For more information on RTCs, please visit the M-RETS Renewable Thermal Tracking System Website.
Smart Energy Carbon Offset projects
Your enrollment helps Smart Energy purchase carbon offsets from innovative environmental projects like biodigesters on dairy farms that can turn waste into an on-demand renewable energy source. The Average Home enrollment option will prevent more than 20 pounds of greenhouse gas emissions from entering the atmosphere every day.
Bear Creek Watershed
Bear Creek Watershed - Astoria, OR
B6 Dairy - Gooding, ID
Captured methane from the anaerobic digestion of manure at this family farm generates about 1 million kilowatt-hours of renewable electricity every month.
Castelanelli Brothers Dairy
Castelanelli Brothers Dairy - Lodi, CA
Davis Landfill - Layton, UT
Farm Power Lynden
Farm Power Lynden - Lynden, WA
Captured methane from an anaerobic digester was used to generate renewable electricity. The resulting heat waste heated commercial greenhouses.
Farm Power Misty Meadow
Farm Power Misty Meadow - Tillamook, OR
This family-owned dairy diverts manure from a 14-million-gallon lagoon to a 1-million-gallon anaerobic digester, where captured methane is used to generate renewable electricity.
Farm Power Rexville
Farm Power Rexville - Mt. Vernon, WA
Farm Power Tillamook
Farm Power Tillamook - Tillamook, OR
Five family-owned dairy farms pipe manure from about 2,500 cows to a central digester, where captured methane is used to generate renewable electricity.
Lochmead Farms - Junction City, OR
This family-owned dairy turned waste from about 1,100 cows into renewable electricity.
Moses Lake - Moses Lake, WA
This ENERGY STAR®-rated facility diverts organic waste and potato trim from lagoons to an anaerobic digester. Captured methane is used on-site as a source of renewable natural gas.
Oak Lea Dairy
Oak Lea Dairy - Aumsville, OR
This small family-owned dairy uses captured methane to generate renewable electricity—enough to power about 300 homes in Oregon each year.
Roseburg LFG Energy - Roseburg, OR
This project captures methane emitted from the Roseburg Landfill municipal waste facility. The captured methane is then refined and sent to a 1.6-megawatt energy plant to generate renewable energy.
Shaan Seet Improved Forest Management Project - Prince of Wales Island, AK
This project sequesters atmospheric carbon by preventing commercial timber harvesting activities from occurring on this 8,891 acre area of old-growth forest. Owned by Shaan Seet Inc., an Alaska Native Claims Settlement Corporation that provides economic development for the community of Craig (Shaan da) on the west side Prince of Wales Island, this project will also improve wildlife habitat, protect biodiversity, and protect water quality for local fisheries.
TMF Biofuels - Boardman, OR
Captured methane from co-digested organic waste and cow manure generates about 4.8 million megawatts of renewable electricity annually.
Van Warmerdam Dairy
Van Warmerdam Dairy - Galt, CA
Manure from roughly 1,400 cows power a 600 kilowatt-capacity generator, which produces peaking power for Sacramento Municipal Utility District.
Whiteside Dairy - Rupert, ID
Captured methane heated farm buildings and generated renewable electricity.
Winston Creek Forest Carbon Project - Lewis County, WA
This project sequesters carbon by extending the rotation time between timber harvests on a 10,088-acre plot of commercial forest. Made up primarily of Douglas fir, the project protects valuable habitat for local wildlife, including the spotted owl and marbled murrelet.
Misty Meadow Dairy
How we select carbon offset projects for Smart Energy
NW Natural contracts with accredited third-party verification bodies to procure verified carbon offsets on behalf of the Smart Energy program.
All Smart Energy carbon offset projects meet rigorous quality standards and ensure environmental integrity. Projects must:
- Ensure greenhouse gas emission reductions are in addition to business-as-usual activities.
- Apply quantification protocols that generate a conservative volume of emission reductions.
- Be rigorously monitored and third-party verified.
- Contribute to sustainable development goals, such as protecting water quality and creating jobs.
