Propane
Our approach to propane solutions is about providing you with as many options as possible. We develop a custom plan that fits your needs and budget to service home heat customers, commercial operations, and agricultural businesses.

Our residential propane solutions offer the most diverse and customer-friendly contracting in south central Wisconsin and northern Illinois. With multiple contract options, we customize a program to fit your needs by offering Even Pay, Prepay, Booking, and Budget contracts.
You can also take advantage of low market pricing and the opportunity to lock-in propane pricing with multi-year contracts. And our contracts never have any hidden or rental fees.

As with our residential propane services, we have flexible contracting options to fit your needs and budget, including Even Pay, Prepay, Booking, and Budget contracts. To ensure equipment availability, you can contract with us for multiple seasons.
Propane Autogas
The popularity of propane autogas vehicles is increasing throughout the country. Fleets including buses, law enforcement, and delivery vehicles are discovering that propane autogas offers reduced emissions, year-round reliability, and the lowest total cost-of-ownership available. We help fleets take advantage of this clean-burning fuel’s economic and environmental benefits.
With propane autogas, you’ll reduce your impact on the environment, but also see the benefits in your bottom line. Autogas vehicles need fewer oil and filter changes, require less maintenance, aren’t affected by cold weather like a diesel vehicle, and don’t require compliance additives.
Our knowledge and skill in this area, along with the strong relationships we’ve established to set up new and updated refueling stations across Wisconsin, have made us the area’s leader in propane autogas.
Refined Fuels
Cenex Premium Diesel Fuels have been designed to operate with higher efficiency and less downtime, which is why we’re a partner and provider of Cenex Premium Diesels.
