Natural Gas

Located in Brampton, Ontario, the Goreway Power Station is an 875 MW natural gas fueled, combined cycle facility. The facility can provide electricity to Ontario’s power grid 24 hours per day, 7 days per week, but primarily operates during intermediate and peak demand periods. Capital Power acquired Goreway Power Station in June 2019 from Goreway Power Station Holdings Inc., which is jointly owned by JERA Co. Inc., and Toyota Tsusho Corporation. The facility has a 20-year Accelerated Clean Energy Supply Contract expiring in June 2029 with the Ontario Independent Electricity System Operator (IESO).Capital Power is proposing a new energy project for the Goreway Power Station. The project is in response to the call for new power generation and capacity being administered by the IESO.

Quick Facts

  • State-of-the-art emission controls
    • Combines the best qualities of clean-burning natural gas with state-of-the-art emission controls, such as Selective Catalytic Reduction (SCR) to reduce smog-forming NOx emissions.
      • NOx emissions are considerably less than 8.5% of the allowable limit
      • SO2 emissions are less than 1% of the allowable limit
  • Noise control
    • More than $10 million invested in noise abatement equipment and building layout design to reduce or eliminate typical noise associated with electricity generation
    • Noise emissions were extensively modeled and validated to confirm compliance with the Ontario Ministry of Environment and Climate Change (MOECC) Environmental Compliance Approval (ECA)
  • Water use
    • Steam exhausted from the facility’s steam turbine is directed to a dry air-cooled condenser (ACC), where it is condensed and recycled back to the heat recovery boilers as feedwater and therefore using less than 5% make-up
  • Biodiversity and habitat stewardship
    • Facility’s design and site layout were developed with careful attention to ensure existing natural habitats are preserved (only 21% of the 20-hectare site developed)
    • Buildings and support facilities are situated to avoid impact to Mimico Creek and its floodplain area that crosses the westerly section of the property
    • Facility’s setback from Goreway Drive preserves the existing natural area along the easterly portion of the site with trees, wetland, meadow and stream
    • To augment the site’s existing natural features and to provide additional visual screening, additional features have been introduced across the site including a storm water management pond, berms, a variety of plants, shrubs and tree plantings


Proposed Energy Project to Meet Regional Needs

Capital Power is proposing a new energy project for the Goreway Power Station, which is located at 8600 Goreway Drive.

The project is in response to the call for new power generation and capacity being administered by Ontario’s Independent Electricity System Operator (the “IESO”). If we are successful in this process, the new project would be built within the existing footprint of the Goreway site and would consist of either:

  • A new natural gas-fired generation unit of up to 250 MW; or
  • A Battery Energy Storage System (“BESS”) that would have a maximum output of up to 100 MW.

Only one of these is expected to be built.

Option A: Natural Gas Generation Unit

The IESO has indicated that natural gas generation remains an integral part of the generation mix and continues to be required to ensure grid reliability. Gas plants are often located near large population centres to support local power needs, avoiding the need for potentially expensive or disruptive transmission projects. A natural gas facility helps to facilitate renewable energy growth by providing a backstop to intermittent generation from wind and solar energy facilities (e.g. when the wind isn’t blowing or the sun isn’t shining). The proposed additional turbine at the Goreway Power Station would provide these characteristics, while also providing local energy support to economic growth in the region. The cost effective and reliable long duration energy supply provided by a new natural gas turbine would help attract new, large scale business ventures that bring significant employment and economic opportunities to the Brampton region.

Option B: Battery Energy Storage System (“BESS”)

The BESS would store energy to help meet power demand spikes when renewable energy is not sufficient to meet load (i.e. power demand). The BESS would be charged during times when there is a surplus electricity available on the system, which would generally occur during the off-peak hours and would discharge energy during the time of system need, which is generally during the peak demand or when there is a disruption in supply in the system. With the combination of the existing facility and the proposed BESS, Goreway will help meet increasing local and provincial demand by providing critical backup generation support to the Ontario grid that is reliable (there when you need it) and flexible in support of intermittent renewable sources of generation.

Helping meet Growing Electricity Needs – Locally and Regionally

In December 2021, the IESO released its Annual Planning Outlook (“APO”) which identified significant need for capacity at both the bulk system and regional levels. At the system level the IESO is projecting an increasing deficit of generation capacity starting in 2025. The primary causes for the estimated shortfall are 1) an increase in load growth; 2) lack of investment in new supply; and 3) retirement and refurbishment of Ontario’s nuclear fleet.

The need is greatest in the GTA area. The deficit, with the assumption that all existing generators remain in operation and are available, reaches 5,000 MW by around 2035 and almost 10,000 MW around 2042.

Provincial and Local Regulatory Approvals Required

In addition to approvals from the City of Brampton, additional approvals will be required from the Ministry of the Environment, Conservation and Parks (MECP). Public consultation activities will be undertaken as part of these regulatory processes.

Community Investment

At Capital Power, we contribute to the communities in which we operate with the aim of building a sustainable future for all. We engage our neighbours, consider their interests and build real relationships. And, we aim to source supplies and services locally for our operations, as well as hire from the community. At Goreway Power Station:

  • We pay approximately $1,000,000 in property tax each year, contributing annually to community tax bases, supporting the improvement of infrastructure, roadways, and community services.

We give back where we live and work by supporting local organizations and our employees’ community participation through our corporate giving programs.

Request Community Support

The Goreway facility is an excellent strategic fit to our growth plans given its size, excellent operating history, location, and remaining contract term to 2029.
