The following is the Michigan Public Service Commission (MPSC) Staff's calculation for regional fuel mix, emissions, and nuclear waste. This has been prepared as directed by the Commission in its orders in Case No. U-12487, dated June 5, 2001 and December 20, 2001, concerning supplier disclosure standards as required under 141 PA 2000. Suppliers may rely upon this information to meet their disclosure requirements for the year 2008.

For the 12-month Period
November 2007 - October 2008
Regional Average Fuel Mix
Used to Generate Electricity in
Michigan, Illinois, Indiana,
Ohio, and Wisconsin
 Coal     69.8 %
 Nuclear 23.9%
 Gas 4.4%
 Oil 0.5 %
 Hydroelectric 0.6 %
 Renewable Fuels Total 0.9 %
    Biofuel - -
    Biomass 0.01 %
    Solar - -
    Solid Waste Incineration * 0.33 %
    Wind 0.15 %
    Wood 0.43 %

Emission/Waste
Regional Average for
Fossil/Nuclear Generation for
Michigan, Illinois, Indiana,
Ohio, and Wisconsin
Pounds per Megawatt-hour
 Sulfur Dioxide 11.33
 Carbon Dioxide 2,089.9
 Nitrogen Oxides 3.25
 High-Level Nuclear Waste .0083

(1) *Includes landfill gas; (2) "- -" Not applicable or negligible; (3) Emissions rates are per megawatt of regional fossil generation; Nuclear waste rate is per megawatt of regional nuclear generation; (4) Sulfur Dioxide, Carbon Dioxide, and Nitrogen Oxides are calendar year 2006 emissions, with 2007 generation using actual generation from Jan - Aug and estimated from Sept - Dec 07; (5) High level nuclear waste produced is based on discharged fuel for a time span approximately 2 years in length ending in 2002.  This data is collected irregularly by the Department of Energy; the amount nuclear fuel burned (and discharged) per megawatthour has changed very little in recent years according to DOE.
