This special report illustrates the recent and ongoing efforts of EEI members to develop transmission to support renewable resource integration. Total investment in these transmission projects is approximately $21 billion, based on current estimates provided by EEI’s members. In addition to the projects identified in this report, there are a number of important transmission projects in development that support the integration of renewable resources whose investments will be less than $20 million.

This report is intended to give a broad, but not comprehensive, perspective on the variety of transmission projects being built to support renewable resource integration. It must be noted that, given the nature of power flows and grid design on alternating current (AC) transmission systems, a transmission project cannot be dedicated to a specific renewable resource project or limited to transmitting renewable energy.

A brief profile of each participating EEI member company is included along with the representative projects provided.  Information included for each project submitted includes a project map, brief description, estimated cost, current status, potential partners and intended benefits.
