BHE Canada and BHE U.S Transmission own and operate the Montana Alberta Tie Line (MATL). MATL is a 345 kilometre, 230 kV merchant electricity transmission line with a capacity of 300 MW and the potential to further increase available capacity in the future. MATL is located on rights-of-way, in road allowances or highway rights-of-way.

A right-of-way refers to the physical space in which a transmission line is located and includes areas on either side of the transmission line structures and the conductors, which are the wires that carry the electricity.

A road allowance or highway right-of-way is a strip of land set aside by the Province of Alberta for roads, but also provides for other facilities, such as powerlines. Transmission lines are often located within 1 metre of the boundary of the road allowance or highway right-of-way to reduce the impact on private landowners. Road allowance may be developed or undeveloped, but the same safety precautions always apply.

To ensure the safety of the public and the reliability of Alberta's electrical system, we work with landowners, developers, municipalities and companies to ensure that our transmission lines in rights-of way, road allowances and highway rights-of-way are properly managed.


MATL is an International Power Line (IPL) that crosses the Alberta/Montana international borders. As such, MATL is obligated to comply with Canadian Energy Regulator (CER) International Power Line Damage Prevention Regulations (IPLDPR). Written approval from BHE MATL is required for any of the following work prior to the work beginning:


To help us to ensure your safety and the reliability of the electrical system, you must contact us by filling out a Right-of-Way Use Application when you are planning any use of or alteration within BHE-Canada's rights-of-way.

In addition, some land uses and alterations outside the BHE-Canada right-of-way but near transmission lines have the potential to impact safety and reliability. For this reason, BHE Canada requests and strongly encourages you to notify us if you are planning to use land, build new structures, or make alterations to existing structures that are adjacent to a right-of-way or transmission line by filling out a Proximity Notification form. We recommend that you contact us if your use or alteration is within 30 metres (approximately 100 feet) of the nearest transmission line conductor. This includes uses or alterations adjacent to BHE Canada transmission lines in road allowance or highway right-of-way. We will review your proposal and will work with you to develop safe working conditions as necessary.

You may also have a legislative obligation to contact BHE Canada for certain developments in proximity to a utility right-of-way. Industrial land uses, such as gravel pits, mines, well sites and pipelines may be subject to special regulations. The following table lists industrial uses and the recommendation notification distances:

Pipelines 300 m (~985 ft) Canadian Standards Association (CSA) standard C22.3 NO.6-13 Principles and Practices of Electrical Coordination Between Pipelines and Electric Supply Lines
Well Sites 100 m (~330 ft) Alberta Energy Resources Conservation Board (ERBC) Directive 056
Seismic Exploration Activities 60 m (~200 ft) Exploration Directive ED2006-15
Gravel Pits 30 m (~100 ft) Alberta Occupational Health & Safety Code subsections 535(1) and 535(2)



There are two types of forms that may be submitted to BHE Canada:

If you are unsure whether your proposed activity is within the BHE Canada Right-of-Way, please contact us at and we can assist you.

Once you have determined the appropriate form to submit, please complete the following steps:

  1. Complete the Right-of-Way Use Application OR Proximity Notification (PDF).
  2. Complete the appropriate crossing/data sheet or drawing for the type of work. See the attached for Samples of Work (PDF) document and Blank Survey Data Sheets (PDF).
  3. Submit all documents to

If you have a detailed cover sheet that includes all of the information above, you can submit that in lieu of 1 and 2. However, please include whether you are submitting a Right-of-Way Use Application or Proximity Notification in the subject of your email.

Please allow up to two weeks for feedback on Proximity Notifications, and up to four weeks for Right-of--Way Use Agreements.

For uses within the right-of-way, BHE Canada will review your completed Right-of-Way Use Application and look at whether your proposal is compatible with Alberta's Electrical Utility Code and Occupational Health and Safety Standards, as well as BHE Canada's safety, reliability and access requirements. If your proposal is found to have a potential impact, BHE Canada will work with you to identify and recommend adjustments or modifications that could be made to your proposal to minimize these impacts.

If your application is compatible with applicable regulations and our requirements, we will create an BHE Canada Right-of-Way Use Agreement for you to sign and return. Please do not start your activities until you have signed and returned the Right-of-Way Use Agreement. In some situations, we may request an on-site meeting to review safety procedures prior to any work being completed.

For uses or alterations adjacent to the Right-of-Way or transmission line, BHE Canada will review your proposal and determine whether any additional safe working conditions are required. To ensure your safety, we request that you do not start your activities until you have received written confirmation from BHE Canada.

A number of factors are taken into consideration during the review process, including:

Thank you for your cooperation as we work to ensure the safety of the public and the reliability of the electrical system.

We look forward to working with you.


Examples of uses and activities in the right-of-way or adjacent to a transmission line that do not require review and coordination with BHE Canada:

Examples of uses and activities in and adjacent to the right-of-way or transmission line that require coordination with BHE Canada:

Examples of uses and activities that will not be approved within the Right-of-Way:


Roads that lie immediately adjacent to or within the boundaries of the right-of-way will be considered on a site-specific basis. Roads, including driveways, are generally compatible within the right-of-way provided that:


Transmission line wires can sag in increased hot or cold weather and may swing in strong winds. Trees or plants growing in or along the edge of a transmission line right-of-way can become a potential hazard when there is a risk of the tree falling or branches dropping onto the transmission line. Trees that become a fire risk or a safety hazard will be identified for removal at BHE Canada's discretion. Before any work commences, we contact property owners to discuss the work required.

Landscaping and agricultural uses are generally compatible within the right-of-way provided that:

  • The height and species of trees are approved by BHE Canada and, if required, are trimmed to maintain safe clearance from transmission line wires
  • Landscaping does not limit BHE Canada's crews and equipment in accessing the transmission facilities
Use of construction vehicles and machinery within the right-of-way may be compatible provided that:
  • Vehicles and machinery do not approach within a minimum 1 metre (3 feet) horizontal distance of BHE Canada's facilities (towers, poles and anchor wires)
  • Agricultural vehicle height (including antennas) does not exceed 4.3 metres (14 feet) to highest point (such as an antenna)
  • Soil stability and drainage are maintained so as not to impact BHE Canada's facilities

Note that many transmission facilities can safely accommodate agricultural vehicle heights greater than 4.3 metres (14 feet). If your vehicle exceeds 4.3 metres (14 feet), please contact BHE Canada at


  • Parking is temporary
  • All parked vehicles meet the minimum vertical electrical clearance requirements as specified by BHE Canada in writing
  • A minimum 4 metres (13 feet) zone for access is maintained around BHE Canada's facilities (towers, poles and anchor wires)
  • Protective barriers are installed, at your expense, for BHE Canada's facilities, if required
