​Project backgrou​​nd

To accommodate Capital Power's Repowering Project, EPCOR plans to expand the Genesee Substation. If approved, this will involve building a new 236 metre by 236 metre fenced substation site west of the existing Genesee Substation.​

Project details

This project will also include modifications to the existing Genesee Substation site, constructing two 500 kV bus extensions, and constructing 138 kV transmission lines to connect to nearby existing electrical infrastructure (see map for details). The 138 kV transmission lines will be strung on steel H-Frame and A-Frame structures.​

The planned ex​​pansion will include the following new equipment and transmission lines:

  • Addition of one (1) 500/138 kV transformer

  • Addition of four (4) 500 kV circuit breakers

  • Addition of eight (8) 138 kV circuit breakers

  • Construction of approximately 210 metres of 500 kV bus extension

  • Construction of approximately 210 metres of 500 kV bus extension

  • Construction of approximately 200 metres of 138 kV transmission line (to be named 12TC2L)

  • Construction of approximately 255 metres of 138 kV transmission line (to be named SST1L)

  • Construction of approximately 255 metres of 138 kV transmission line (to be named SST2L)

  • Construction of approximately 255 metres of 138 kV transmission line (to be named SST3L)​

Modifications to the existing Genesee Substation site and transmission lines will include:

  • Removal of one (1) 500/240/138 kV transformer

  • Removal of eight (8) 138 kV circuit breakers

  • Relocation of 160 metres of 138 kV transmission line (named 430L)

  • Relocation of 170 metres of 138 kV transmission line (named 8L10)​​​​

Construction details

​Site sele​c​​tion

The proposed site for the expansion was selected because it is in close proximity to the existing Genesee Substation site and Capital Power's Repowering Project, provides sufficient access for construction and maintenance vehicles, and minimizes environmental impacts. A retention pond, approximately 110 metres by 90 metres and 3.5 metres deep, will be constructed in the southwest corner of the substation expansion to ensure proper drainage.​​

​Work sp​​a​​ce

All work areas will be safe and secure and all construction activities will be in accordance with EPCOR’s health, safety and environmental procedures and guidelines. If this project is approved by the Alberta Utilities Commission (AUC), EPCOR will require temporary workspace around the proposed substation expansion site and a laydown area during construction (approximately 85 metres by 275 metres).​​

Schedule

​EPCOR is beginning our public consultation program and invites you to contact us to discuss the project. Over the next few weeks, EPCOR project team members will con​​tact landowners, occupants, and interest holders who are directly adjacent to the proposed substation expansion site. Once we have received feedback on the project, we will file a Facility Application with the AUC for approval to build and operate the new facilities. EPCOR follows AUC Rule 007 for transmission facilities and feedback gathered during consultation will be included in our Facility Application.​​ Please provide feedback on this project by February 1, 2022.

Regulatory process

About the Alberta ​Utilities Commission (AUC)

Alberta's electric system is regulated by the AUC. The AUC is an independent quasi-judicial agency that ensures the delivery of Alberta's utility service takes place in a manner that is fair, responsible and in the public's interest. The AUC must approve this project before EPCOR can begin work. For more information about how you can participate in the process, please visit the AUC website.

About the Alberta Electric System Operator (AESO)

The AESO is an independent, not-for-profit organization responsible for the safe, reliable and economic planning and operation of the provincial transmission grid. For more information about why this project is needed, please refer to AESO's Need Overview or visit www.aeso.ca​. If you have any questions or concerns about the need for this project or the proposed transmission development to meet the need you may contact the AESO directly. You can also make your questions or concerns known to an EPCOR representative who will collect your personal information for the purpose of addressing your questions and/or concerns to the AESO. This process may include disclosure of your personal information to the AESO.​​
