The Bonnybrook Energy Centre, a proposed 165 megawatt natural gas-fired facility to be located on the Canada Malting site in Calgary, would generate electricity and capture waste heat.

A proposed cogeneration facility in Calgary would generate electricity and capture waste heat.
ENMAX Energy Corporation could build the plant in the southeast end for the city.
“To be honest, we have some engineering to do and we have some permits to submit to the Alberta Utilities Commission, in order to get the plan approved,” said Kim Pfeifer, vice-president of business development with ENMAX.
“The applications address air emissions, noise, water use and extensive stakeholder consultations with the community. We also have a separate application for wastewater treatment.”
The Bonnybrook Energy Centre will be a 165 megawatt (MW) natural gas-fired facility, located on the Canada Malting site in Calgary.
The project would be completed in two phases.
The first phase will include installing two natural gas-fired turbines, two once-through heat recovery steam generators and one steam turbine.
“This is a complex project, because we are talking about thermal energy and waste water,” said Pfeifer.
“Cogeneration projects and combined heat and power projects are generally quite complicated.”
In Phase II, power generation capability will be increased by adding an additional 40 MW turbine and a complementary steam generator.
This will increase the thermal energy output and provide additional heat.
The second phase would connect to the city’s district energy systems, which allow more than one building to be heated or cooled using energy produced in, and distributed from, a central plant.
A network of underground pipes connects the central plant to individual buildings. Thermal energy in the form of hot water, steam or chilled water is distributed to the buildings and return pipes bring the water back to the central plant to be heated or cooled again.
A new water reclamation facility will be built as part of the energy centre to recover the malting process water and the wastewater storage lagoon, currently in use by Canada Malting, will be eliminated.
“Building generation plants closer to where the power is needed most makes good economic and environmental sense,” said ENMAX Energy CEO Gary Holden.
“The facility will be close to downtown, so minimal electricity will be lost in comparison to plants that require lengthy transmission lines.
“Bonnybrook will also capture waste heat for use by nearby industry, offering considerable benefits to the environment overall.”
The proposed facility would cost just less than $200 million and provide heat for Canada Malting, as well as heat to downtown buildings through a network of underground insulated pipes.
The site is close to existing gas pipelines and electricity transmission lines. It is expected to take six to 12 months to get regulatory approval.
If successful, construction will start in the second quarter of 2010.
