The potential energy from the region is effectively unlimited

1. 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)

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

Wind energy from the best resources is less expensive than any other new power plant

Levelized Cost of Energy1

$ / MWh

1. 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)

The big challenge is transmission

Existing High Voltage Transmission Lines(500–999kV AC and HVDC)

Clean Line’s projects

connect the regions where wind power is

most abundant;

existing extra-high voltage transmission lines do not

Clean Line projects

Clean Line has four projects that can help solve the challenge…

…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 AND OUT OF STATE PROJECTS
