  1. Transmission and the Growth of Wind Energy November 2011

  2. The central United States has some of the world’s best wind resources Average 80 m wind speed. Source: NREL, AWS

  3. The potential energy from the region is effectively unlimited Top States in Terms of Wind Resource Potential Top ten states have 5,239 GW of high capacity factor wind potential, compared to 2009 average US electricity load of 425 GW Based on windy land area in Lower-48 states with a gross capacity factor (without losses) of 40%+ at 80-m height, and the wind energy potential from development of the “available” windy land area (excludes areas such as wilderness areas, parks, urban areas and water features) Source: NREL; AWSTruewind; AWEA

  4. Wind energy from the best resources is less expensive than any other new power plant Levelized Cost of Energy1 $ / MWh Mid-point of Lazard’s LCOE estimates, except for lower-end for coal (no carbon capture). Wind uses lower-end LCOE estimate (for best quality wind) Source: Lazard

  5. The big challenge is transmission Existing High Voltage Transmission Lines (500–999kV AC and HVDC)

  6. Clean Line has four projects that can help solve the challenge… Clean Line projects Rock Island Clean Line’s projects connect the regions where wind power is most abundant; existing extra-high voltage transmission lines do not Grain Belt Express Centennial West CA Plains & Eastern Existing High Voltage Transmission Lines (500–999kV AC and HVDC)

  7. …but we need a lot of help to make the projects happen STATE POLITICAL SUPPORT LEVEL PLAYING FIELD FOR INDEPENDENTS STATE SITING WHERE POSSIBLE FEDERAL SITING AS A BACKSTOP LONG TERM CONTRACTS FROM UTILITIES IN-STATE ANDOUT OF STATE PROJECTS
