Strathcona refinery cogeneration unit and related electrical facilities

To improve the energy efficiency of its Strathcona refinery, Imperial has approved funding for a cogeneration unit that would produce approximately 41 megawatts of electricity on a yearly basis.

The cogeneration unit would be built within the existing Imperial refinery, located at 3400 Baseline Road, near Edmonton, Alberta.

The proposed cogeneration facilities consist of a gas turbine, a heat recovery steam generator (HRSG) and related electrical infrastructure.

Electricity produced by the cogeneration unit would provide power to the refinery, which would meet approximately 75 to 80 percent of the refinery’s needs and significantly decrease consumption of energy from the Alberta grid.

The waste heat from the gas turbine would be transferred to the heat recovery steam generator to produce steam used in the refining process. The construction of the proposed cogeneration facilities would enable the refinery to retire one of its four existing boilers.

Construction of these facilities would significantly reduce the amount of electric power purchased by the refinery, thus increasing its energy efficiency.

Proposed project schedule

  • In February 2015, the Alberta Utilities Commission (AUC) granted approval for Imperial to construct and operate the cogeneration unit and related infrastructure.
  • In November 2016, Imperial submitted an application to the AUC to amend the approval by deferring the construction completion date from December 31, 2016 to December 31, 2019.
  • On November 1, 2017, Imperial announced its Board of Directors had approved funding for the construction and operation of a cogeneration unit at Strathcona refinery. The $250M capital investment is another significant milestone for Strathcona, and reinforces the importance of the refinery to Imperial’s success.
  • Should regulatory approvals and other factors be met, Imperial will plan to move forward with construction in 2017. Start-up of the facilities could occur in early 2020.
