Carbon capture utilization and storage connection

To support Heidelberg Materials Canada Limited’s (Heidelberg Materials) new net-zero cement production facility, EPCOR is proposing to construct a new 138 kilovolt (kV) single circuit, above-ground transmission line. This new transmission line would connect Heidelberg Materials’ proposed new substation to an existing EPCOR transmission line (711L).

Project overview

The project includes:

Constructing approximately 1.9 km to 2.8 km of 138 kV transmission line to connect the proposed facility to the existing 711L transmission line;
Installation of new fibre optic cable along the route;
Upgrading the existing 711L transmission line to support the additional capacity required; and
Adding or modifying existing equipment as required for the above transmission developments.

Project map

We have identified four route options for the proposed new transmission line to connect the existing EPCOR transmission line to Heidelberg Materials’ proposed new substation. Although there are multiple options shown, only one route will be built. We need your input to find the best route.

If approved, the 138 kV transmission line will be built using mostly composite fibreglass poles ranging in height from approximately 20 to 30 metres. Non-typical structures such as steel poles, poles with wider bases, and the use of guy wires may be required at certain locations along the line.

For some of the route sections we are proposing to build the new transmission line in the same alignment as the existing distribution lines in the area. In this scenario, every second or third distribution pole (overbuilt line) would be replaced with a new transmission pole. The distribution equipment would then be attached onto the new transmission pole, underneath the transmission insulators and wires. For one of the proposed route options shown on map (red/yellow), we are proposing to build the new transmission line parallel to the existing distribution line.

Additional potential structure types.

In Spring/Summer 2025, EPCOR will apply to the Alberta Utilities Commission for approval to construct the new transmission line and associated project work. If approved, construction would be planned for 2026.

Depending on the work location, landowners and businesses can expect to see activity that is typical to construction, including company/contractor vehicles and equipment. The construction area will be fenced and/or marked as a restricted area. Periodic lane closures may be required in the project area to complete this work.

Power outages

There will likely be power outages during construction. These would occur in 2026/27. EPCOR will be working with affected customers to determine the best approach to schedule and mitigate these outages. If a planned power service interruption is required to complete the work, and you are affected, we will notify you in advance.

Noise

The proposed work will create typical noise associated with construction. We will take measures to ensure we comply with the City of Edmonton’s Community Standards Bylaw for Noise Control. If it’s necessary to temporarily exceed acceptable noise levels, we will work with the City of Edmonton to receive necessary permits.
