Abstract
The Hydro-Québec system has an installed capacity of 32 GW for an annual generation capability of about 188 TWh. The system is made up of 51 hydro-plants, 4 thermal plants, and 1 nuclear plant. The storage capacity is distributed over 75 reservoirs (25 major) throughout 8 major river systems. The system is highly hydro dominated (93 % of the installed capacity) and characterised by large water storage capacity and by remote generation located in the north of the province of Québec in Canada. The radial transmission system is composed of 17,500 km of lines to supply the consumption areas located in the south of the province. In a continuous effort to increase the global efficiency of its generation system in a North American restructured market, the new Hydro-Québec Generation division has developed the PPCT (4) system as one of its major optimization tools.
