Montana-Alberta Tie-Line

The Montana Alberta Tie Line (MATL) is a 214-mile (345-kilometer), 230-Kilovolt transmission line that interconnects the electricity markets of Alberta and Montana. It is the first power transmission line between Alberta and Montana, and the largest transmission line project in Montana in the past 20 years.

The MATL runs from a substation outside of Lethbridge, Alberta to one near Great Falls, Montana. It allows much-needed energy fl ow in both directions, ensuring more reliable supplies of electricity which will make both Montanans and Albertans less vulnerable to power outages. The MATL will enable the development of new wind-energy projects by linking this renewable and emission-free source of power to consumers across North America.

The MATL project was partially financed by Western Area Power Administration (WAPA), that received $3.25 billion in federal stimulus funds for transmission lines for renewable energy. WAPA received 200 inquiries for transmission line projects, with MATL rising to the top because it was shovelready with contracts in place for the energy.

The Morrison-Maierle survey team began working on this project in 2006, providing preliminary boundary, control, and routing survey tasks. As the project progressed survey services were expanded to include boundary surveys for easement acquisition, topographic surveys, control surveys, wetland delineation surveys, cultural surveys, right of way staking, and structure staking.

In 2011 Enbridge, Inc. acquired Tonbridge, Inc., and expanded Morrison-Maierle’s services to include program management of the entire line, in both the U.S. and Canada.
