American Transmission Company
• Started in 2001 (helped by WI act 204 in 19999)
• Consolidation– MG&E, Alliant Energy,
Wisconsin Public Service Corp. (Integrys Energy) and We Energies
• ~32 miles– $152 Million +
• Part of $4 Billion plan for T-lines
Guarantied Rate of Return
• Guarantied return of 12.2% on investment in WI, 9.15% outside WI– $18.24 Million return
for Beltline T-line
• Return rates started by FERC and then picked up by Gov. Thompson in 1999 (Act 204).
Sources Energy and Demand
• Last year needed 421,475.017 MW at any given second in the US.
• Sources– Coal– Natural Gas– Hydro– Nuclear – Wind – Solar
• Electricity Market is in 15 Min windows
• Federal contracts • Missing power output in
window results in $10,000 fine

Other Solar Cells
• Thin-Film Solar PV cells – Lower cost and
efficiency ~10%
• Transparent solar cell – 1% efficient – Researchers seeking 5%
efficiency
Wind
• Different designs– May or may not have
gearbox
• Limited to maximum efficiency of 60% from energy in air

Growth of wind
• Tax credits for wind offered at $.01 -.02/ KWH– Get upfront cash grants to accelerate process
• Decreasing cost of power electronics • Using power electronics to allow for variable
blade speed (modify TSR) increasing efficiency• Improving Capacity factor
