Your Smart Energy enrollment helps fund projects that reduce greenhouse gas emissions and contributes to renewable energy innovation in our region.

Smart Energy 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

By extending the time between timber rotation, this Forest Stewardship Council-certified watershed forest sequesters atmospheric carbon and helps provide clean drinking water.

B6 Dairy

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

This family-owned dairy uses captured methane from diverted manure to generate renewable electricity for the farm.

Davis Landfill

Davis Landfill - Layton, UT

Captured methane is piped to Hill Airforce Base, where it is used to generate renewable electricity.

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

The digester sits between two dairies and generates electricity with the captured methane from manure and municipal food waste.

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

Lochmead Farms - Junction City, OR

This family-owned dairy turned waste from about 1,100 cows into renewable electricity.

Moses Lake

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

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

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

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

Whiteside Dairy - Rupert, ID

Captured methane heated farm buildings and generated renewable electricity.

Winston Creek

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.

We have three children and all three have a passion for the dairy industry. We think it's a great move, and a great future for the farm.

How we select projects for Smart Energy


NW Natural contracts with The Climate Trust®, an internationally recognized Portland-based nonprofit, to ensure that only verified high-quality offsets are purchased and retired on behalf of the Smart Energy program.


All Smart Energy carbon-offset projects are vetted by The Climate Trust® to 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.
