Butterfield and Milky Way Dairy Projects
Avolta, a renewable energy company focused on originating, developing, owning, and operating renewable natural gas (RNG) projects, contracted with Nacelle on the development of two RNG projects in Arizona. Collectively, these projects are one of the largest biogas projects currently being developed in the United States. When complete, the projects will generate over 675,000 MMBtu of RNG annually which will ultimately be distributed as renewable transportation fuel. The two projects will create 200 construction jobs and sustain long-term employment at the operational facilities once the plants are commissioned. The Butterfield and Milky Way projects are scheduled to begin delivering gas into a Southwest Gas Pipeline during the first and second quarters of 2022, respectively. Both facilities will be operated and maintained by Nacelle Solutions.
- Integrated with Existing Equipment

These facilities are a family business that collectively care for more than 60,000 cows. The de Jong family has a deep history rooted in dairy farming, dating back to 1620. The de Jongs want to keep the family tradition alive and help create the next chapter in the family legacy through sustainable innovation.
