In March 2016, we submitted a facility application to the Alberta Utilities Commission (AUC) for the necessary approvals required to expand the existing switchyard for EPCOR's Genesee 330P substation, which is located adjacent to the Genesee generating units (Application # 21426-A002). On May 26, 2016, we received approval from the AUC to begin construction (Decision No. 21426-D01-2016).

Construction was originally scheduled to begin spring of 2017 and completed winter of 2018, however the project has been delayed and is now scheduled to begin in the spring of 2019 and completed by February 2021. EPCOR will be applying to the AUC for an updated permit and license to reflect the new construction schedule.


Project details

The expansion of the substation switchyard was described in materials distributed by Capital Power prior to their applying for their new facilities. But as a reminder, included here are drawings and information outlining the nature and scope of the switchyard expansion. EDTI’s project would include:

  • The substation will expand by approximately 200 metres to the east;
  • The substation will contain four new 500 kV breakers and other associated equipment, surrounded by a chain link fence;
  • The substation will have a short transmission line connecting to the new generating units.
  • No other transmission lines will be installed as a result of this project.
  • If Approved, we anticipate construction will be complete by the winter of 2018/2019
