Some of what we do


MMW packages power generation systems for net metering, sales via Power Purchase Agreement, backup power, or other needs. Our turn-key units include every component you need, working together with one company responsible for the package. They are built using open source equipment and software that keeps YOU in control of your equipment—not the factory technician or the sales rep. Our systems are built to prioritize serviceability using commonly available parts and consumables with minimal proprietary roadblocks.


The Fabrication team specializes in providing custom solutions to biogas product needs. We build heat exchangers, gas processing systems, and packages to meet whatever system challenge you’re facing. We’ve operated biogas systems in wet climates and dry, hot and cold. We know what it takes to stand up to real world biogas handling needs.


Tired of having 6 different controllers that don’t talk to each other? MMW can build comprehensive control packages, or help integrate what you already have. Our design and construction of electrical control systems are optimized for on-farm/in-field duty where reliability and serviceability are key. We also have a top tier electrical team that can work with any voltage up to 24,000.


Our technicians can field-service most brands of biogas engines in a growing western USA service territory. We also provide in-field or in-factory engine rebuilds, new or retrofit installations, controls upgrades, and specialty troubleshooting of the engine and auxiliary systems—even if we didn’t install it.
