Future of Path Ratings

As the Western Interconnection grows increasingly complex, adapting the Path Rating Process and transfer capability methodologies is becoming crucial for maintaining Bulk Power System (BPS) reliability. The rapid growth of regional energy demands, changing grid dynamics, and complex transmission interactions now make traditional path rating and flow-based methodology concepts essential for modern grid planning. This central resource hub hosts technical data and high-level stakeholder resources to build a shared understanding of reliability components and to safeguard the stability of our changing power system. As processes and approaches are improved, developed, or retired, they will be tracked here.
