MPSC - Calculation for regional average fuel mix

The following is the Michigan Public Service Commission (MPSC) Staff’s calculation for regional average fuel mix, emissions, and high-level nuclear waste. This data has been prepared as directed by the Commission in Order Case No. U-12487, dated June 5, 2001 and December 20, 2001, concerning supplier disclosure standards as required under 2000 PA 141. Suppliers may rely upon this information to meet their disclosure requirements for the year 2011.

Regional Electric Power Fuel Sources, Emissions, and Nuclear Waste
for Electric Supplier Disclosures for the Year 2011
Issued: November 08, 2011

Fuel Source For the 12-month Period August 2010 - July 2011	Regional Average Fuel Mix Used to Generate Electricity in Michigan, Illinois, Indiana, Ohio, and Wisconsin
Coal	64.66%
Nuclear	24.03%
Natural Gas	7.11%
Oil	0.42%
Hydroelectric	0.68%
Renewable Fuels Total	3.09%
Biofuel	0.13%
Biomass	0.40%
Solid Waste Incineration*	0.42%
Solar	0.01%
Wind	1.70%
Wood	0.44%

^* Includes Landfill Gas

Emission/Waste ¹	Regional Average for Fossil/Nuclear Generation for Michigan, Illinois, Indiana, Ohio, and Wisconsin (lb/MWh)
Sulfur Dioxide	8.21
Carbon Dioxide ²	2,186
Nitrogen Oxides	2.01
High-Level Nuclear Waste	0.0083

¹ Sulfur Dioxide, Carbon Dioxide, and Nitrogen Oxides are calculated for the calendar year 2009. High-level nuclear waste is based on discharged fuel for a time span of approximately 2 years in length ending in 2002.
²Carbon Dioxide emissions for the historical years 1998-2008 have been revised by EIA due to changes in emission factors.
