This week council was informed by Hydro Ottawa that Ottawa Holding Inc., through their affiliate Portage
Power, has acquired two additional hydroelectric generating stations from TransAlta Renewables
located on the Mississippi River in the Town of Appleton and Galetta Falls.
Together these facilities generate an average of 12.5 gigawatt hours annually, increasing Portage
Power’s total green generation capacity from 128 to 131 megawatts, enough to power approximately
110,000 homes. These new acquisitions build on our strength and position as the largest
municipally-owned producer of green energy in Ontario.
The Appleton Generating Station (GS) is located on the Mississippi River, in the town of Appleton,
Ontario. The plant was built in 1994 on the site of an old mill and consists of a powerhouse building,
intake channel and control dam.
The Galetta (GS) is located near Almonte, Ontario on the Mississippi River where it connects with the
Ottawa River. Originally built in 1907, the plant consists of a control dam, intake canal, powerhouse and
Both new facilities are EcoLogoM certified by the Environmental Choice Program .
I’m pleased to report that this acquisition not only aligns us with Canada’s goal of a 100 per cent
emissions-free electrical grid by 2035, but that it also takes us one step closer to our net-zero
operations goal, and our commitment to lead our city towards a smart energy future, together.
