EnerNex led the Eastern Wind Integration and Transmission Study (EWITS), a culmination of an effort that spanned two and one-half years. The study team began by modeling wind resources in a large part of the Eastern Interconnection and finished by conducting a detailed wind integration study and top-down transmission analysis.

The study resulted in information that can be used to guide future work. A number of other studies had already examined similar wind integration issues, but the breadth and depth of the analysis in EWITS was unique. EWITS built on the work of previous integration studies, which looked at considerably smaller geographic footprints, focused almost exclusively on wind integration, and did not include transmission. EWITS took the next step by expanding the study area and including conceptual transmission overlays.
