Enbridge Completes Acquisition of Tonbridge Power Inc.

October 13, 2011

CALGARY, ALBERTA--(Marketwire - Oct. 13, 2011) - Enbridge Inc. (TSX:ENB) (NYSE:ENB) announced today the closing of its acquisition through a plan of arrangement of all outstanding common shares of Tonbridge Power Inc. ("Tonbridge") for $20 million.

As part of the plan of arrangement, Enbridge will also repay approximately $50 million of debt incurred in the development of the Montana-Alberta Tie-Line (MATL) power transmission project being developed by Tonbridge. Enbridge will also inject further funding to complete the first 300 megawatt (MW) phase of MATL as well as a low cost expansion to 550-600 MW. The total cost to Enbridge for both phases of MATL is expected to be approximately $300 million, of which approximately half is being funded through a low cost 30-year loan from the Western Area Power Administration of the U.S. Department of Energy.

MATL is a 345-kilometer transmission line from Great Falls, Montana to Lethbridge, Alberta, designed to take advantage of a growing supply of electric power in Montana, including green power production, and the buoyant power demand of Alberta. Required permits for the first phase of MATL have been obtained and the project has secured long-term, take-or-pay contracts for the system's entire northbound capacity. In addition, Tonbridge also has a 200-km southern extension of MATL, the Green Line, in early development.

"We are delighted to welcome the Tonbridge team to Enbridge," said Richard Bird, Executive Vice President, Chief Financial Officer and Corporate Development, Enbridge Inc. "Tonbridge management will bring their power transmission project development expertise and experience, and with Enbridge adding our strong core competencies in project management and execution, we will focus on bringing the line into service in mid-2012. We also look forward to working with our new team to act on future opportunities to grow and expand our power transmission business."
