Abstract: A multisite complex is analysed in northern Quebec to decide the level of equipment needed that will supply firm energy at the best possible unitary price. Four possible sites were chosen on a preliminary screening. The production capabilities of the complex vary from 2,000 to 16,000 GW. h per year depending on the level of equipment (dams, stations) installed. The option of adding a diversion from an adjacent watershed is also considered. The choice was based on the critical period concept; this 15 years period was extracted from the existing historical sample that was 35 years long. The energy demand had a monthly modulation with the peak occurring in January. The optimization was done with LP and the verification by simulation. Since the LP was deterministic the rule changed from year to year, for this reason the firm energy results were too optimistic. These values were downgraded once the simulation was implemented with a fixed operating rule. The decision-maker considered realistic the firm energy values obtained with the LP chosen structures in place, operated with a rule that was optimized by trial and error but that was constant over the whole simulation period. The results show the variation of GW. h unit cost of firm energy versus total yearly firm energy for the case with diversion obtained by LP and simulation.
