We are repowering Genesee 1 & 2 to natural gas combined cycle (NGCC) generation units from coal-fired units. Located entirely within the footprint of the existing Genesee Generating Station, the repowering project involves installing two new Mitsubishi M501JAC gas-fired combustion turbines and Vogt triple-pressure heat recovery steam generators, while utilizing the unit’s existing steam turbine generators.
The two repowered units will provide an additional 518 megawatts (MW) of net capacity totaling 1,338 MW. The repowered assets will utilize best-in-class NGCC technology and are expected to set a new standard for gas generation efficiency in Canada.
Construction activity began in 2021 and is anticipated to create ~900 people years of construction work with a peak forecast of ~500 workers.
Genesee 1 & 2 are both scheduled to become dedicated NGCC units in 2024 which will take Capital Power off coal by the end of 2023. Both units will be converted to run in simple cycle mode before the completion of the repowering of each unit.
Future proposed expansion plans
The repowered Genesee 1 & 2 project is proposed to be complimented by a battery energy storage system (“BESS”) to ensure capacity from the units will be available to serve Alberta in circumstances when it might otherwise be constrained due to transmission system restrictions. Pending regulatory approval, the BESS would be used to store, and later deploy, up to 210 MW of energy, using lithium-ion batteries. The project would employ best-in-class battery storage technology and be amongst the first large-scale storage projects in Alberta.
Also located within the footprint of the Genesee Generating Station, the BESS would create no air emissions and would not require additional water supply during the electricity storage and deployment processes. Capital Power will be applying to the Alberta Utilities Commission (“AUC”) for approval to construct and operate the BESS with an anticipated in-service date of late 2024. The total expected capital cost of the Repowering and BESS projects is approximately $1.2 billion.
- Additional 518 MW of net capacity
- Carbon capture ready
- Best-in-class NGCC technology making Genesee 1 & 2 the most efficient NGCC units in Canada
- Providing reliable and cost-effective energy while contributing to a 40% reduction in emissions from the Genesee site
- ~60% decrease in carbon emissions intensity from ~0.93 tonnes of CO2e per MWh when burning coal to 0.36 tonnes CO2e per MWh
- Over 80% decrease in NOx emissions intensity
- At least 50% water usage reduction for the repowered units
Consultation and Engagement
We value and consider local community interests and priorities. We engage government, employees, local communities, investors, stakeholders, and Indigenous communities. Our goal for every project, every facility and every initiative, internal and external, is to build, operate, and align with the interests and priorities of those closest to, and most impacted by, our operations.
