Criteria used by Canadian utilities in the planning and operation of generating capacity

The author reviews the reliability criteria used by Canadian utilities in regard to planning and operating generating capacity. These results have been obtained from surveys conducted by the Power System Reliability Subsection of the Canadian Electrical Association. These surveys cover both operating and planning generating capacity criteria. In the case of adequacy assessment, a comparison of the different utility criteria is presented using the IEEE Reliability Test System. It is concluded that virtually all Canadian utilities now use probabilistic techniques in planning future-generating-capacity requirements
