Wanner Family Farm ProjectHB
NativeEnergy helped the Wanner family build a methane digester that reduces greenhouse gas emissions and produces surplus renewable energy.
Carbon Project Type: Farm Methane Power
Location: Narvon, Pennsylvania, U.S.
Volume: 35,337 metric tonnes
Capacity: 130 kW
Seven generations of the Wanner family have developed the Pride-N-Joy Farm located in Narvon, Pennsylvania, in eastern Lancaster County. The farm was founded in 1840, and it is operated today by Alfred Wanner and his two sons, Matt and John, with 600 milking cows. Their goal is to keep the farm viable for future generations.
In early 2006, the Wanners began to improve their manure management by constructing increased manure storage capacity, manure solids separation, and an anaerobic digester. The anaerobic digester, completed in the summer of 2007, produces approximately 2,000 kWh of electricity each day, more than three times the amount of electricity the farm currently uses.
With plans to sell the surplus generic electricity to their power provider, the Wanners turned to NativeEnergy to provide an upfront purchase of the digester’s RECs and carbon offsets to help fund the project.
Other benefits from the project include producing digested manure solids, which after composting can be sold to landscaping contractors. Digested manure liquids, which have reduced odor compared to untreated manure, will be irrigated on nearby fields as natural fertilizer.
Sustainable Development Benefits
- Displaces polluting local grid-based electricity with renewable energy
- Reduces 35,337 metric tonnes of greenhouse gas emissions
- Reduces the farm’s nutrient runoff, odor, and pathogens
- Creates safer organic fertilizer to apply to the fields
- Reduces energy and nutrient management costs for the farm
- Creates bedding for the cows, replacing expensive and hard-to-find wood shavings
- Preserves open space, local agriculture, and the traditional community
This project is a collaborative effort between the Wanner family and NativeEnergy.
Validation and Verification
This project was validated using Climate Neutral Network methodologies. The project’s performance is third-party verified every other year.
This project meets NativeEnergy’s stringent additionality criteria, as our funding was necessary to the project’s implementation.
