ITC Attains Public Utility Status in Wisconsin

ITC Holdings Corp.

today announced that The Public Service Commission of Wisconsin (PSCW) has approved its applications to become an authorized public utility holding company in the state and for its operating subsidiary ITC Midwest LLC to become a Wisconsin public utility. The approvals issued by the PSCW on May 7 represent ITC Midwest's first step toward developing its portion of a regional transmission project in Wisconsin and Iowa called multi-value project (MVP) #5 by MISO – the Midcontinent Independent System Operator. This project, a new 345 kV line from the Dubuque, Iowa area to the Madison, Wisconsin area, was identified because it is expected to improve service reliability, reduce system congestion and facilitate the interconnection of lower-cost generation resources in the region. The project is a reflection of ITC's continuing efforts to facilitate the development of regional transmission projects. "We are grateful to the Wisconsin commission and staff for their prompt and thoughtful attention to our applications," said Doug Collins, president of ITC Midwest. "We look forward to bringing our track record of success and corporate citizenship in other Midwest states to customers in Wisconsin." About ITC Holdings Corp. ITC Holdings Corp.
