Description (excerpt):
The North American grid is a complex machine that has evolved over many decades and integrates a network of generation, transmission, and distribution systems across vast geographic areas. 5 As a result of the changing resource mix6 and extreme weather, interregional energy transfers play an increasingly pivotal role. More than ever, a strong, flexible, and resilient transmission system is essential for grid reliability. NERC, as the Electric Reliability Organization (ERO), remains focused on assuring reliability throughout this energy transformation. As evidenced during recent operational events, more needs to be done to support energy adequacy8 to be able to continuously meet customer demand. This is the reliability risk that the Interregional Transfer Capability Study (ITCS) seeks to identify and mitigate through additions to transfer capability9 as directed in the Fiscal Responsibility Act of 2023.
