NERC’s ITCS Canadian Analysis Finds Grid Increasingly Vulnerable

WASHINGTON, D.C. – NERC has published its Interregional Transfer Capability Study (ITCS) Canadian Analysis of transfer capability between transmission planning regions and the reliability benefits of enhancing cross-provincial and cross-border transmission. The analysis reflects the crucial role that Canadian systems play in the interconnected North American bulk power system and is an unprecedented assessment conducted using a common approach and a consistent set of assumptions. 

The study, which complements NERC’s ITCS published last year, found that Canadian systems are increasingly vulnerable to extreme weather and transmission limitations. It also identified the potential for energy inadequacy in all of the 12 weather years studied ​and found that enhancing transmission interfaces could reduce the likelihood of energy deficits during extreme conditions.
