Dairy Digesters


Renewable Energy That Works.

Dairy Digesters & Renewable Natural Gas (RNG)
Development, Financing, and Operations

What We Do

Dairy Digester Design & Development Plans

Design and Projections

We prepare capital budgets, site plans, and operational projections to help dairy operators scope a Producer-Owned digester; or we can finance and own the project ourselves at no cost to the dairy. We have the best digester team in the country to procure grants, energy contracts, and carbon credit funding.

Methane Digester Development in Progress

Project Development

Our RNG development company has developed the majority of all West Coast digesters built in the past decade. Grid interconnection, regulatory permits, computer-aided design, financial management, and construction oversight, we do it all. In-house, on time, done right.

Digester Operations & Maintenance Work


Just like dairy cows, methane digesters require attention. Our team supports our digesters 24x7, with remote operations, on-call support, parts, utility scheduling, and repairs. Managing a dairy is already a massive undertaking. All operations of the digester are handled by our team so you aren't left trying to master another industry.

Producer-Owned or Developer-Owned.
Your Choice.

If you want to own a digester, Maas Energy Works will handle the entire process, start to finish. All design, financial projections, grant financing, grid interconnection, regulatory permits, procurement, and construction management are included.

When the project is online, we will operate the site for you with 24/7 monitoring and operations support. 


Our digester projects average 94% up-time.


If you prefer not to own the digester, we can develop, build, and operate the facility at no cost to you, paying you a guaranteed annual rate per cow.
