Benefits of economy transactions and wheeling in Canada

As part of a review of possible measures for increasing inter-utility cooperation and enhancing transmission access in Canada, the National Energy Board carried out a study to quantify some potential wheeling benefits. Computer simulations were performed, incorporating a planning time horizon and real system data, to determine potential benefits from bilateral exchanges of economy energy and the additional benefits which could result from various wheeling arrangements. From these simulations, the potential benefits for each system involved as well as the net potential benefits for the region were determined. The CPU time for the simulations ranged from 14 hours to 46 hours on a VAX 8200 mini computer. Sensitivity analyses were also performed to establish the dependency of the benefits obtained on some system parameters used in the studies
