The demand for power is increasing as Calgary continues to grow. The Alberta Electric System Operator (AESO) has determined
the existing transmission system in south Calgary will become overloaded as the demand for power rises. The reliability of your
power supply is reduced as transmission lines become overloaded and the likelihood of power outages increases.
The AESO has identified the need to add
a new 138 kV transmission line between
ENMAX No. 65 Substation and ENMAX No.
41 Substation via ENMAX No.54 Substation
in order to prevent transmission line
overloads in the South Calgary area.
To meet this need, ENMAX Power
Corporation has identified two viable
transmission routes – a preferred and an
alternate. The total length of the proposed
transmission line to be constructed is
approximately 14 – 22 kilometres depending
upon the approved route. New equipment
will be added at ENMAX Substations No.
65 and No. 41 to accommodate the new
transmission line
Project Update – FATD Macleod Trail
ENMAX Power is proposing a new 138 kV transmission line between a substation located at 88 St. SE and Hwy 22X and 213
Shalom Way SW. Alberta Transportation has advised ENMAX Power, the original proposed routes through Macleod Trail and
Stoney Trail SE will conflict with construction of the future expansion of this intersection as part of the Southwest Calgary Ring
Road project. ENMAX has redesigned the routes through this intersection to accommodate the road infrastructure.

The Preferred transmission line route will now cross Stoney Trial and proceed north along the east side of Macleod Trail, and then
cross Macleod Trail to connect to the original route along the west side. The Alternate transmission line route will still continue
north along the west side of Macleod Trail, but extend further west around the interchange.

Transmission Structures
The proposed single circuit transmission structures are selfsupporting steel monopoles and have a height of 18 – 24 metres
(58 – 78 feet). Distance between structures will be between
100 – 125 metres (325 – 410 feet).
The revised preferred route will require nine poles; three fewer
than the original preferred route and will be located on the east
side of Macleod Trail. The revised alternate route will require nine
poles resulting in the addition of one extra pole.
Environment
At ENMAX, we strive to reduce impacts to air, water, land and wildlife during all our operations. We do this by:
• Working with regulatory agencies including the City of Calgary, Alberta
Environment and Sustainable Resource Development, Alberta Parks, Fisheries
and Oceans Canada, and Environment Canada to ensure all required approval
and permits are obtained before starting any project.
• Complying with relevant environmental legislation, regulations, guidelines,
policies and operating approvals.
• Developing a site specific Environmental Management Plan for each project
to address and mitigate potential impacts to the environment. The plan is
reviewed onsite with ENMAX employees and contractors.
• Conducting frequent on-site inspections to ensure workers are adhering to
the Environmental Management Plan, and that all mitigation measures are
effective.
• Conducting follow-up site visits to ensure impacted areas are remediated.
• Maintaining and continually improving upon our Environmental
Management System, which is based on the International Standard ISO
14001 and supports our Corporate Environment Policy.
Regulatory Process - Foothills Area Transmission
Development South Calgary
NEED
Alberta Electric System Operator (AESO) identifies a
need to upgrade transmission system
DIRECTION
AESO directs Transmission Facility Owner (TFO),
in this instance ENMAX Power, to prepare a
Facility Application in accordance with the Electric
Utilities Act.
STUDIES
TFO conducts necessary studies to ensure
transmission routing is the safest, most economical,
with the least impact on landowners and
the environment
ENGAGEMENT
TFO conducts a public engagement program as
identified in Alberta Utilities Commission (AUC)
Rule 007 to all potentially affected landowners,
occupants and residents adjacent to the project.
APPLICATION
TFO consolidates information from engagement and
studies, and prepares final Facility Application and
submits to the AUC.
AUC REVIEW AND APPROVAL
AUC reviews application and issues a notice in local newspapers. Interested
parties are offered an opportunity to participate in the application process.
Refer to the AUC booklet for information on the regulatory process following
submission of the Facilities Application.
Understanding Electric and Magnetic Fields
• Electric and magnetic fields (EMFs) are found everywhere
electricity is used from household wiring to power lines.
ENMAX understands public concerns with EMF and in order to
provide current information to the public and our employees,
we continue to monitor the issue through our work with the
Canadian Electricity Association’s EMF task group.
• While there are no EMF limits related to long term health
effects, some countries and organizations (such as the World
Health Organization) have adopted the 2010 ICNIRP guideline
of 2000 mG (milligauss) for acute effects.
• Based on our modelling for the TUC route, ENMAX expects
that the magnetic field at the nearest property line will be less
than 5.5 mG.
Thank you for attending our open house.
We hope we’ve answered your questions and have your
comments.
Please take a couple of minutes to fill out a comment card.
Your input will be included in our consultation report which
will be incorporated into our application to the AUC.
