Probabilistic Transmission Planning

Probabilistic transmission planning has become increasingly necessary and important in recent years. Some utilities like British Columbia Transmission Corporation (BCTC) have started their practice toward this direction. This article addresses basic aspects of probabilistic transmission planning. The probabilistic method is not intended to replace the deterministic criterion but adds one more dimension to enhance the transmission planning process. An actual example at BCTC is provided to demonstrate the application of probabilistic transmission planning.
