Cascade Power Project

Cascade is a high-efficiency, combined cycle natural gas-fired generating facility.

Cascade Power Project is a 900 megawatt (MW) combined cycle power generation facility being constructed in Yellowhead County, approximately 12 kilometres southwest of Edson, Alberta. The Project is located on crown lands on a 52-hectare site and will have the capacity to supply over 8% of the province’s average electricity demand. The facility will utilize modern, highly efficient industrial turbines, fuelled by natural gas, and will commence operations in 2023.

Project Need

As Alberta transitions off coal-fired generation, the province will need new supplies of clean electricity to meet the growing demand for power. Combined cycle power generation facilities, such as Cascade, will provide efficient, reliable on-demand power for Albertans. .

Local Economic Activity

The construction and operations of the Project will play an important role in the local economy by providing jobs during construction that will benefit the local and Indigenous communities, businesses and suppliers, as well as provide a base of additional tax revenue to Yellowhead County.

It is anticipated the facility will take three years to construct, employing approximately 600 workers at the peak of construction. The anticipated work effort is expected to require 3,000,000 work-hours in the local area. Once operations commence, 25 direct, long-term skilled jobs will be created in the community.

The total capital investment associated for the Project is approximately $1.5 Billion.

Environmental Benefits

The Cascade Power Project will lead the transition to clean electricity generation in Alberta as the province transitions off coal-fired power. Once complete, Cascade is expected to be the largest and most efficient combined cycle power plant in the province, producing approximately 62% less CO2 equivalent per MWh than existing coal-fired generation, and at least 30% less CO2equivalent per MWh than a typical coal-to-gas conversion. With Alberta contributing over 50% of Canada’s GHG emissions from electricity generation, the Project is expected to result in the largest emissions reduction opportunity in the country’s electricity sector.

Cascade has quick-ramping technology, meaning it can turn on and off quickly, supporting the integration of renewable energy projects in Alberta.

How They Work

Natural gas combined cycle power generation facilities are a high efficiency, environmentally attractive form of power generation necessary to meet the growing demand for electricity in Alberta.

A combined cycle power facility uses both a gas and a steam turbine simultaneously to produce up to 50 per cent more electricity from the same amount of fuel than a traditional simple cycle facility. This is because all of the wasted heat from the gas turbine is recovered and converted into high-pressure steam, which drives the steam turbine and generates additional electricity. 

Project Partners

Cascade is owned by a consortium of global infrastructure investors and local First Nations. 

About OPTrust

With net assets of almost $22 billion, OPTrust invests and manages one of Canada’s largest pension funds and administers the OPSEU Pension Plan (including OPTrust Select), a defined benefit plan with over 96,000 members. OPTrust was established to give plan members and the Government of Ontario an equal voice in the administration of the Plan and the investment of its assets through joint trusteeship. OPTrust is governed by a 10-member Board of Trustees, five of whom are appointed by OPSEU and five by the Government of Ontario.

About Indigenous Communities Syndicate LP

The Indigenous Communities Syndicate LP (ICS) is a consortium of six First Nations, owned by Alexis Nakota Sioux Nation, Enoch Cree Nation, Kehewin Cree Nation, O’Chiese First Nation, Paul First Nation and Whitefish Lake First Nation. The ICS was formed to make a meaningful investment in the Cascade Power Project.

240 kV Whisky Jack Switchyard

Cascade is connected to the Alberta Interconnected Electrical System through the Whiskey Jack switchyard.

Air Cooled Condensers

Steam turbine exhaust is condensed in the air cooled condensers (ACC) and then returned to boiler feedwater.

Generation Building Houses

Two Siemens SGT6-PAC 8000H gas turbine driven generators and two SST6-PAC5000 steam turbines. The steam turbines and the gas turbines are coupled with the 450 MW generators.

Water Treatment Building

Water for the steam cycle is treated here to ensure cleanliness of the HRSG and steam turbines.

Drum Plus Heat Recovery Steam Generators (HRSG)

Stack and Selective Catalytic Reduction (SCR) reduces the amount of NOx in the stack emissions.

Main Site Entrance

Access to site from Highway 47.

Ammonia Storage

Ammonia is used in the SCR for emissions treatment.

Gas Turbine Air Inlet Filtration

Air for the gas turbine is taken in through high efficiency filters to ensure no foreign objects enter the turbines.

Generator Step-up Transformer

Power from each generator is stepped up in voltage in order to be transmitted through grid.
