Dairyland Power invests in landfill biogas plants

La Crosse, WI, June 1, 2006 — Dairyland Power Co-op has invested in more renewable energy for its members by purchasing the electricity from two new landfill gas-to-energy (LGE) generating facilities, owned by Waste Management Inc.

The generating facilities are sited at the Timberline Trail Landfill near Bruce, WI, and the Central Disposal Landfill near Lake Mills, Iowa. Both came online in spring 2006.

The natural byproduct of the residential waste landfills, methane gas, is the fuel used to generate the renewable energy. The 3.2 megawatt (MW) Timberline Trail facility can power 2,700 homes. The 4.8 MW Central Disposal facility can power 4,000 homes.

Dairyland receives energy from a third such plant, the 3 MW ONYX Seven Mile Creek Landfill gasto-energy facility in Eau Claire, WI. The generating plant, owned and operated by Dairyland, was brought online in 2004 and is expected to expand in 2007.

Dairyland also supplies renewable energy to its member distribution co-ops from its Flambeau Hydro Station near Ladysmith, WI, and from participation in two wind farms in southwestern Minnesota. In addition, Dairyland operates three “cow power” manure digester facilities at dairy farms in its service territory.
