Bonnybrook power station is a proposed 165-megawatt (MW) gas-fired power plant in Calgary in the province of Alberta, Canada.[1] It is also called the Bonnybrook Energy Centre.

This project was first announced in 2009 as a cogeneration project to be built by ENMAX on "the Canada Malting site" and would provide heat for Canada Malting and other nearby buildings. The project would have two phases:

"The first phase will include installing two natural gas-fired turbines, two once-through heat recovery steam generators and one steam turbine. In Phase II, power generation capability will be increased by adding an additional 40 MW turbine and a complementary steam generator."[1]

In December 2015, EBI delayed the project for four years due to "weak market conditions".[2] At that point, ENMAX described the plant in this way:

"The Bonnybrook Energy Centre (BEC) will use efficient combined-cycle technology that generates electricity from combustion turbines fuelled by natural gas, and from a steam turbine fuelled by heat produced by the combustion turbines. Heat from the combustion turbines is also used to produce hot water that could potentially be used by other businesses."[2]

The Alberta Utilities Commission granted approval until June 30, 2020.[3]

In November 2019, no additional progress seems to have been made and the project appears to be cancelled.
