Montana Alberta Tie Line (MATL)
The Montana Alberta Tie Line (MATL) is a 230 kilovolt (kV) transmission line connecting the Montana electrical grid at Great Falls, Montana and the Alberta electrical grid at Lethbridge, Alberta. The line is 345 kilometres long and has a capacity of 300 MW with the potential to further increase available capacity.
MATL has been an essential part of the electrical energy system in both Alberta and Montana since going into service in 2013.
BHE Canada owns the Canadian portion and manages the facility's day-to-day operation. BHE U.S. Transmission owns the portion of the line in the United States.
Key benefits:
- There is no cost to ratepayers for the operation of the transmission line, the owners fully fund the cost
- MATL has transmitted a net 2,629 GWh of electricity into Alberta, providing enough energy to power approximately 38,000 homes annually
- More than five times the amount of energy has been transmitted north into Alberta than south into Montana
Sale of existing MATL southbound capacity
Starting on or around October 2023, MATL will be undertaking an Open Solicitation process for its remaining southbound capacity. Capacity will be allocated in 20 MW increments and for a term of greater than one year up to five years.
Interested parties should complete the Open Solicitation registration form available in the “Open Solicitation” folder of the left-hand navigation pane at https://www.oasis.oati.com/matl/.
