Modernization and Interregional Planning Surge

The week ending March 13, 2026, was marked by widespread operational stability across North American wholesale power markets as systems transitioned into the spring shoulder season. Real-time energy prices stayed relatively low and stable across most footprints, reflecting moderate seasonal demand and healthy reserve margins. This calm in operations provided a backdrop for a surge in long-term strategic and regulatory activity, most notably the unveiling of a landmark interregional transmission portfolio by the Southwest Power Pool (SPP) and the Midcontinent Independent System Operator (MISO). The proposed multi-billion dollar project suite targeting the markets' shared seams signals a significant step forward in addressing the cross-border constraints that have historically limited renewable energy integration and regional reliability.
