Average Fuel Mix Comparisons
Beginning January 1, 2002, the Customer Choice and Electric Reliability Act gave all consumers in Michigan the option to choose the company that provides their electric supply. When choosing a supplier, it is important to know the sources of generation different companies may have. Included here is information regarding Wisconsin Public Service's fuel mix and emissions compared to other regions.
The environmental characteristics of your electricity as reported to the Michigan Public Service Commission pursuant to Public Act 141 of 2000 are as follows:
Average Fuel Mix Comparison: WPS vs. Regional Average
The information shown in the tables below includes data for different time periods, due to the availability of such data. In making energy purchase decisions, you may find it more helpful to compare the fuel mix data of individual suppliers to that of other individual suppliers, rather than comparing the fuel mix of any one supplier to the regional fuel mix.
| Fuel Source | Percentage of Fuel Type Used to Produce WPS's Total Electricity |
Percentage of Fuel Type Used to Produce Electricity in Michigan, Illinois, Indiana, Ohio and Wisconsin |
|---|---|---|
| Coal | 70.05 | 68.90 |
| Nuclear | 22.20 | 23.30 |
| Gas | 2.58 | 5.60 |
| Oil | 0.16 | 0.60 |
| Hydroelectric | 4.03 | 0.60 |
| Renewable Fuels | 0.98 | 1.00 |
| Biofuel | - | - |
| Biomass | 0.01 | 0.06 |
| Solar | - | - |
| Solid Waste Incineration | 0.71 | 0.35 |
| Wind | 0.13 | 0.05 |
| Wood | 0.11 | 0.54 |
| Other - Tire Derived | 0.02 | - |
- The information shown is for the WPS system, which includes generation in Wisconsin but does not include generation of any of its affiliate companies. It is for the period of November 2007 through October 2008. The regional information is for the 12-month period of September 2006 through August 2007.
- Solid Waste Incineration includes landfill gas.
- " — " denotes "not applicable" or "negligible."
- In this table, the fuel mix data for the electricity supplied to you by WPS includes regional average fuel mix data from Michigan, Illinois, Indiana, Ohio and Wisconsin as a proxy for the actual fuel mix of certain electricity purchased by WPS. This is because the actual fuel mix of that purchased electricity could not be discerned. Purchased electricity accounted for 20.91% of the electricity supplied by WPS during the relevant period.
Airborne Emissions and High-Level Nuclear Waste Comparison: WPS vs. Regional Average
| Type of Emission/Waste | WPS Average | Regional Average of All Generation in Michigan, Illinois, Indiana, Ohio and Wisconsin |
|---|---|---|
| Sulfur Dioxide | 6.90 | 12.40 |
| Carbon Dioxide | 2182.10 | 2088.10 |
| Oxides of Nitrogen | 4.90 | 4.98 |
| High-Level Nuclear Waste | - | 0.0074 |
- Emission rates are pounds per megawatt-hour of regional fossil generation. The nuclear waste rate is pounds per megawatt-hour of regional nuclear generation.
- The regional information for sulfur dioxide, carbon dioxide and nitrogen oxides is for the calendar year 2002. The WPS information is for the 12-month period ending December 31, 2007.
- The regional nuclear waste produced is based on the most recent fuel cycle periods for the region's nuclear plants, ending in 1998 and approximately 2 years in length. The WPS information is for the fuel cycle period of June 2000 to September 2001.
