DOWNTOWN CALGARY TRANSMISSION REINFORCEMENT PROJECT PROPOSED TRANSMISSION LINE STAKEHOLDER NEWSLETTER | MAY 2017 PROJECT OVERVIEW The demand for power is increasing as Calgary continues to grow. The Alberta Electric System Operator (AESO) has determined that the existing transmission system in downtown Calgary can become overloaded under certain conditions. Overloaded transmission lines reduce the reliability of your power supply and increase the likelihood of interruptions in power supplied to homes and businesses. The AESO has therefore identified the need for transmission reinforcement into the downtown area. On November 18, 2015, the AESO filed its Needs Identification Document (NID) for Transmission System Reinforcement in Downtown Calgary with the Alberta Utilities Commission (AUC). On June 1, 2016, the AUC approved the AESO’s NID. To meet this need ENMAX Power Corporation (ENMAX) is proposing to build a new 138 kV transmission line between ENMAX No. 2 Substation located at 3120 – 9 Street SE, and ENMAX No. 8 Substation located at 903 – 4 Avenue SW. For more than 100 years, ENMAX has delivered safe and reliable electricity in Calgary. Moving electricity from the point where it is generated to our customers’ homes and businesses is split into two areas: transmission and distribution. To move our electricity from power generating facilities to local areas, ENMAX Power Corporation relies on a system of high- voltage power lines across Alberta, including our own 288 km network within the city. These transmission lines enter a substation where a transformer reduces voltage to a level that can be safely delivered to customers. Photo courtesy of The Calgary Stampede

PROJECT OVERVIEW
The demand for power is increasing as Calgary continues to grow. The Alberta Electric System Operator (AESO) has determined that the existing transmission system in downtown Calgary can become overloaded under certain conditions. Overloaded transmission lines reduce the reliability of your power supply and increase the likelihood of interruptions in power supplied to homes and businesses.

On November 18, 2015, the AESO filed its Needs Identification Document (NID) for Transmission System Reinforcement in Downtown Calgary with the Alberta Utilities Commission (AUC). On June 1, 2016, the AUC approved the AESO’s NID.
To meet this need ENMAX Power Corporation (ENMAX) is proposing to build a new 138 kV transmission line between ENMAX No. 2 Substation located at 3120 – 9 Street SE, and ENMAX No. 8 Substation located at 903 – 4 Avenue SW.

PROJECT DESCRIPTION
The proposed project consists of the following:
Transmission Line:
• Construct a new 138 kV single circuit transmission line approximately 5.5 km in length, from No. 2 Substation to No. 8 Substation.
• Approximately 2 km would be an overhead line from No.2 Substation to the north side of the Elbow River at 1 ST SE.
• Approximately 3.5 km would be an underground line in a new ductbank and manhole system, from the north side of the Elbow River at 1 ST SE to No. 8 Substation.
• ENMAX is proposing to drill 1 km of the underground construction on 9 ST SW starting at 14 Ave SW to 4 Ave SW, due to heavy rail and LRT crossings. ENMAX is proposing to trench the remaining 2.5 km of underground construction .
• Relocation or reconfiguration of other utilities will be required for the proposed project.
Substations:
• No. 2 Substation: Connect the new transmission line to the existing switchgear.
• No. 8 Substation: Modify the existing switchgear to connect the new transmission line.
• All substation work will be conducted inside the existing control buildings at both substations.
TRANSMISSION POLES
The proposed single circuit transmission poles for the overhead portion will be self-supporting steel monopoles. All poles except one will range in height from approximately 18 to 28 metres (59 to 92 feet) and will be 50 to 160 metres (165 to 524 feet) apart. One pole located near No.2 Substation will be approximately 32 metres in height.
SAFETY AND RELIABILITYCalgarians rely on us every day to provide them with safe and reliable power. As our city grows, so do our needs for electricity. At ENMAX Power, we are committed to providing long-term, innovative solutions to meet the growing demands of our city.

ROUTE DEVELOPMENT
During the process of determining and evaluating possible route options, ENMAX considers impact factors such as residential, commercial, environmental, constructability, cost and visuals. ENMAX conducted a thorough routing and siting program that involved extensive data, information gathering, and evaluation.
After evaluation and assessment of several routes, ENMAX is proposing the route identified in the map enclosed in this package.
PROPOSED SCHEDULE
ENMAX plans to file the Facility Application with the AUC by the end of September 2017. Subject to approvals being granted, construction to begin by mid-2018 with a proposed in-service date of early 2021.
OPEN HOUSES
ENMAX representatives will be available at several open houses to share information, gather your input and address any questions or concerns you may have on the proposed transmission project. We hope to see you there.
