Generation Fleet Efficiency Program

As one of many milestones towards achieving net-zero by 2050, ENMAX plans to reduce or offset 70% of their scope 1 and scope 2 greenhouse gas (GHG) emissions by 2030 from a 2015 baseline. T

This includes their plan to reduce or offset GHG emissions associated with their power generation portfolio by investing in efficiency improvements and new technologies. ENMAX Energy is ENMAX Corporation’s Alberta-based competitive generation and retail business.

Their strategic efficiency philosophy and program includes key investments to reduce the emissions intensity of their fleet while ensuring reliable operations. This approach includes introducing Canada’s first hybrid-electric gas turbine at Crossfield Energy Centre, a project funded by Emissions Reductions Alberta. This unique technology combines a battery energy storage system with an existing natural gas-fueled turbine to provide standby electricity without burning fuel. Commercial operation began in May 2021 and is expected to reduce the run time of the turbine by approximately 80%, avoiding an estimated 45,000 tonnes of GHG emissions annually.

Additionally, the utility upgraded turbines at their Shepard Energy Centre (SEC) by adding leading edge technology components that allow for more output with lower emissions.

As a result, they have been able to reduce facility GHG intensity to below 0.38 tCO2e/MWh (tonnes of carbon dioxide equivalent per megawatt hour), which is already Alberta’s industry leading low emissions benchmark facility. In 2022, ENMAX is planning a turbine upgrade at the Calgary Energy Centre and expect a similar reduction of emissions at that facility.

Since 2018, their generation fleet GHG intensity has decreased by more than 100,000 tCO2e per year.
