Key players
AltaLink
AltaLink is an independent company that owns and operates approximately 11,800 kilometres of transmission lines and 270 substations. We provide electric service to more than 85 per cent of Albertans and own the majority of the transmission system in central and southern Alberta.
The Alberta Electric System Operator (AESO)
The AESO is an independent, not-for-profit entity responsible for the safe, reliable and economic planning and operation of the Alberta Interconnected Electric System. The AESO determines the need for transmission reinforcement and directs Transmission Facility Owners, such as AltaLink, to submit a Facility Application for permitting and licensing to construct and operate transmission facilities.
The Alberta Utilities Commission (AUC)
The AUC is a quasi-judicial agency that ensures the fair and responsible delivery of our utility services. The AUC is the provincial regulator responsible for reviewing Facility Applications. AUC approval is required before construction of facilities can occur.
Southern Alberta Transmission Reinforcement Project
Alberta’s electrical grid needs more capacity to make room for power generated from new wind farm projects proposed throughout southern Alberta. New transmission lines are required to support this growth and collectively these projects make up the Southern Alberta Transmission Reinforcement Project (SATR).
The Medicine Hat 138 kV Project is included in the SATR. The AESO filed the need for SATR in a formal application with the AUC in December 2008. The AUC completed a public hearing in June 2009 in Lethbridge to review the need for these projects. The AUC approved the need for these projects in September 2009.

The Medicine Hat 138 kV Transmission Project includes:
• A new 138 kV double circuit transmission line from the existing Bullshead Substation to the proposed Bowmanton Substation
• Upgrades to the existing single circuit 138 kV transmission line between the existing Medicine Hat Substation and the existing Chappice Lake Substation area by removing the existing line and constructing a new double circuit 138 kV line
• Some structures may be removed, and some new structures added in the immediate area around both the Bullshead Substation and Medicine Hat Substation
• A new 138 kV single circuit transmission line approximately 800 metres in length connecting the proposed Bowmantion Substation to the existing Chappice Lake Substation
• Additions to the proposed Bowmanton Substation and existing Medicine Hat, Bullshead and Chappice Lake Substations to accommodate the proposed new transmission lines
Landowner compensation
AltaLink is committed to providing fair and reasonable compensation to landowners who may have transmission facilities on their property.
We provide compensation for easements and Annual Structure Payments (ASP) for the land used by our transmission facilities.
Information regarding compensation and the easement acquisition process will be available throughout the consultation process.
Environmental evaluation
The environmental evaluation involves reviewing available databases, maps and other references along with field surveys. It examines:
• Provincial fisheries, wildlife and vegetation inventories
• Alberta natural heritage and cultural area inventories
• Wetlands and water body data
• Environmental literature
• Aerial and roadside reconnaissance of potential routes
• Public input and regulatory consultation
• Rare plant and vegetation surveys
• Wetland and watercourse surveys
• Wildlife surveys
• Soil and geo-technical assessments
The environmental evaluation will help define mitigation measures to prevent or reduce potential environmental impacts.
Route identification process
This diagram shows how we identify potential route options.
Environment
How does AltaLink consider the environment in project planning?
• Incorporate environmental evaluation results into route selection process
• Avoid environmentally sensitive areas
• Where avoidance is not possible, develop mitigation plans to minimize disturbance
• Parallel existing corridors such as roads, pipelines, power lines and quarter lines where applicable
• Ensure routes meet all current environmental regulations
Route identification criteria
The table below lists the general criteria we take into consideration when identifying and refining potential routes.
Criteria Examples
Agricultural • loss of crops • reduced efficiency
of field operations
Residential • loss of developable lands and constraints on development
• proximity to residences
Environmental • alteration of natural areas and interference with outdoor educational opportunities
Cost • construction costs and land acquisition costs
Electrical • reliability and reparability of the line
Visual • visual impact of structures and lines as seen from residences, farms, roads and recreational installations
Special considerations
• electrical interference with radio transmitting stations and other telecommunication equipment etc.
Please let us know if you think there are other important criteria we should consider when refining route options.
Project details
This project involves transmission line development in the Medicine Hat area.
• A new double circuit 138 kV (138,000 volts) transmission line approximately 45 to 55 kilometres in length, from the existing Bullshead Substation (located about three kilometres south-west of Desert Blume) to the proposed Bowmanton Substation (located on the east side of Range Road 43, south of Township Road 144). From the proposed Bowmanton Substation to Township Road 114, the eastern most proposed routing parallels a portion of the proposed East Medicine Hat to Whitla transmission line route.

PROPOSED LINE 674L/675L
The proposed transmission structures will be spaced approximately 140 metres apart (460 feet).
Some route segments follow open and unopen road allowances. In these circumstances structures will typically be placed one metre within the area boundary. Where not on a road allowance a right-of-way 20 metres in width (65 feet) will be required.
• Upgrade the existing single circuit 138 kV transmission line between the existing Medicine Hat Substation (located near the Trans-Canada Highway and Power House Road) and the existing Chappice Substation (located east of Range Road 43, and south of Township Road 144, approximately 800 metres from the proposed Bowmanton Substation) to double circuit 138 kV. The rebuilt line will connect to the proposed Bowmanton Substation, approximately 27 kilometres in length.

Electric and magnetic fields (EMF)
AltaLink’s position on EMF
AltaLink recognizes that some people are concerned about EMF and we treat those concerns very seriously.
Based on more than 30 years of research, national and international health agencies have not concluded that EMF associated with high voltage transmission lines will adversely affect your health or the health of plants and animals.
They have not recommended the general public take steps to limit their everyday exposure to EMF. AltaLink will ensure any problems caused by interference from our facilities are corrected and all applicable guidelines are met.
Where can you find EMF?
• Earth’s magnetic field
• electric facilities
• appliances
• building wiring
Common questions around electrical effects include:
Will there be TV/radio interference?
There is no impact on cable TV. Other impacts can typically be mitigated.
Will Global Positioning Systems be affected?
There is typically no impact.
Will there be wireless internet interference?
There is typically no impact.
Will there be any affect to cardiac pacemakers?
Most have shielding, but we can provide answers to you about the specific pacemaker model.
What about audible noise?
AltaLink meets AUC noise guidelines.
Building and fence induction?
This is mitigated through grounding we install during construction.
What about stray voltage?
This is not caused by transmission lines; it is more typically caused by distribution lines or local wiring.
