The Joint Coordinated System Plan, the first step of a transmission and generation system expansion analysis of the majority of the Eastern Interconnection, estimates the electricity sector will need over $80 billion in new transmission infrastructure to obtain 20% of the region's electricity from wind generation.

This initial analysis, which was performed with participation from major transmission owners and operators in the Eastern U.S., looked at two scenarios to examine transmission and generation possibilities between 2008 and 2024. The first, a Reference Scenario, assumes "business as usual" with respect to wind development, with approximately 5% of the region's energy coming from wind. The second was a 20% Wind Energy Scenario and was based on the U.S. Department of Energy's Eastern Wind Integration and Transmission Study.

"We believe that, although JCSP'08 examined a small set of scenarios with limited variables, this study nonetheless gives a clear idea of the scale of commitment it will take to integrate large amounts of renewable resources into the grid," said John Bear, president and CEO of the Midwest ISO. "This is information we believe that our leaders need to consider as they begin work under a new administration and start defining our energy future."

JCSP'08 estimates that incorporating 5% wind energy (the "Reference Scenario") will require the addition of approximately 10,000 miles of new extra-high voltage transmission at a cost of approximately $50 billion, in addition to nearly $700 billion in total generation capital costs by 2024.
