Dairyland Power Cooperative

Landfill Gas-to-Energy

Members of Dairyland Power Cooperative receive renewable energy from three landfill gas-to-energy (LGE) biogas facilities. Nearly 12,000 homes in Dairyland’s service territory can be powered with by the three LGE power plants.

LGE plants turn something negative—methane gas—into something positive that we all need: renewable energy. The plants are also very efficient power producers, and don’t come with concerns about fuel supply. It’s unlikely landfills will ever run out of garbage!

In 2004, Dairyland received the U.S. Environmental Protection Agency’s Landfill Methane Outreach Program’s Energy Partner of the Year award for the Seven Mile Creek LGE plant. Dairyland was selected for its success launching the innovative plant, and the environmental benefits of the renewable energy facility.

How does it work?


LGE Diagram

The process from curbside garbage to green energy is simple in concept. The trash you put out on the curb is collected and sent to a landfill. As the trash decomposes, it produces methane gas. This natural byproduct of garbage decomposition is the fuel used to generate renewable energy. An LGE facility harnesses the methane gas to power the generators.
