Biomass Power

Making Waste Work

Biomass is a small yet important piece of our diverse energy mix. The energy from waste products – such as wood and agricultural waste and garbage – can be used to produce electricity. Wood waste can be burned as is or converted to a gas and burned in a boiler to produce heat for converting water to steam to run a generator. The same is true for garbage – it can be turned into refuse-derived fuel and burned in a power plant boiler. As garbage or animal waste decays in a landfill or agricultural operation, it produces methane gas, which can be used as a fuel, similar to natural gas, to produce electricity.

While using biomass to produce electricity provides a waste-management solution, it is generally done today on a smaller scale because it is costly and requires a plentiful, steady fuel source, sometimes more than a single waste stream can produce. We operate in several locations where waste wood is plentiful, and we are participating in test projects for growing biomass crops.

Biomass Power on Our System

We own and purchase about 195 megawatts of biomass generation on our systems, enough to power more than 140,000 average-size homes. All of the biomass plants that we own are former coal plants, and in 1979, our Bay Front Generating Plant in Ashland, Wis., became the first investor-owned utility plant to consume waste wood to generate electricity.

How Biomass Power Works

  1. Heat is created by:
    - burning coal, oil, natural gas or biomass fuel or splitting atoms in nuclear fission
  2. to boil water to make steam.
  3. Steam turns the blades of huge turbines...
  4. which spin generators to create electricity.
  5. A transformer increases the voltage to send electricity over...
  6. distribution lines. Then local transformers reduce the voltage...
  7. for you to use.

Energy Saving Tip

What's the point in filling your home with cool or warm air, only to have it disappear? Invest in high quality insulation to help keep temperature-controlled air where it belongs.

Signs of an Overloaded Electrical System

Lights that flicker, dim or blink and warm or discolored wall plates may be warnings of an overloaded electrical system.
