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.
