Manitoba Hydro - Brandon Combustion Turbine Project


Manitoba Hydro


Manitoba, Canada
     
 
 
Manitoba Hydro installed two natural gas-fuelled combustion turbine units at its
Brandon Generating Station. The two units added over 250 MW to the station's
capacity, increasing the overall capacity to nearly 360 MW.

Teshmont worked with the Stations Department of Manitoba Hydro on the
modification of the existing 115 kV substation to accommodate the connection of
the two new combustion turbines. 		 
 
   

Teshmont established the scope of work with Manitoba Hydro, provided project coordination, attended project review meetings, conducted site visits, and interfaced with other Client departments including the site construction group.
