Located in Brampton, Ontario, the Goreway Power Station is an 875 MW natural gas fueled, combined cycle facility. The facility can provide electricity into 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.
By combining 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, the facility’s stack emissions are well below regulatory requirements and only a small fraction of the emission rates of existing coal-fired power plants.
Goreway Power Station has invested more than $10 million in noise abatement equipment and building layout design to reduce or eliminate typical noise associated with electricity generation.
The facility’s noise emissions were extensively modeled and validated to confirm compliance with the Ontario Ministry of Environment and Climate Change (MOECC) Environmental Compliance Approval (ECA).
The 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.
Most conventional power stations utilize either a once-through cooling or evaporative cooling. These conventional cooling systems use large amounts of water and produce a significant amount of plume, especially during the winter season. By contrast, the facility’s air-cooled condensers not only avoid the environmental impacts associated with once-through or evaporative cooling, they also reduce water consumption to levels 95% lower than a conventional evaporative cooling system.
Goreway Power Station is a strong supporter of biodiversity conservation. The facility’s design and site layout were developed with careful attention to ensure existing natural habitats are preserved.
To accomplish this, only 21% of the 20 hectare site has been developed. The buildings and support facilities were situated to avoid impacts to Mimico Creek and its floodplain area that crosses the westerly section of the property. In addition, the Station'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.
