Southdown Station is an 800 MW (nominal net output)
natural gas fuelled combined cycle generating station proposed for
a “greenfield” site in Mississauga, Ontario, west of
Toronto, Ontario. Development of the facility was initiated in response
to the opening of Ontario’s competitive electricity market
and in anticipation of meeting critical need for new electricity
supply in the greater Toronto area. The project is strategically
located to supply voltage support to the heavily developed south
Mississauga/west Toronto area of Ontario’s electric grid.
The project will utilize Mitsubishi Power System’s MHI 501G
combustion gas turbines in a 2x1 configuration. Developed in close
consultation with community stakeholders, the project has incorporated
a variety of environmental mitigation commitments. By incorporating
selective catalytic reduction technology to reduce emissions of
nitrogen oxides, the plant will also be among the country’s
cleanest. An air-cooled condenser will be used, reducing water consumption
by 95% compared to facilities utilizing conventional evaporative
cooling towers. Extensive noise mitigation will be included to avoid
disturbing residential areas and the project site is designed to
incorporate extensive landscaping.
The project has received virtually all approvals required to begin
construction. Sithe Global is pursuing long-term power sales opportunities
for the project so that it may enter into construction. It is projected
that the facility will enter operation within about 2 ½ years
of entering into a such a long term power purchase commitment.
