Environmental Disclosure – Illinois

As part of Illinois’ electricity deregulation process that began implementation in 1998, all electricity suppliers in Illinois must provide environmental information in utility bills four times per year. These include charts and graphs that will help consumers learn more about where their electricity comes from, and how much pollution it causes.

When Illinois is fully deregulated in 2002, consumers will be able to choose their electricity company. Each company will offer a different "mix" of electricity that comes from different sources of fuel. To help the environment, you should choose an electricity supplier that:

  • uses non-polluting, renewable fuels, such as solar, wind, and biomass
  • uses non-nuclear energy
  • uses less coal energy from older, dirtier power plants

Everyutility selling electricity in Illinois shall, on at least a quarterly basis, provide in billing inserts the following information, in a clearly legible manner, to the maximum extent practicable:

  1. A break-down, on a percentage basis, of the known sources of electricity supplied in Illinois. This break-down shall provide percentages of biomass power, coal-fired power, hydro power, natural gas-fired power, nuclear power, oil-fired power, solar power, wind power, other resources and unknown resources purchased from other companies, respectively.
  2. A pie-chart that graphically depicts the above list of electricity sources.
  3. A table that depicts the amounts of carbon dioxide, nitrogen oxides and sulfur dioxide emissions and high-level and low-level nuclear waste attributable to the aggregate known sources of electricity as identified in number 1.
