Hurricane Ida demonstrated that damaged transmission lines and substations can prevent bringing in additional electricity. Grid resilience requires hardening existing transmission corridors, not only building new high-voltage lines. Entergy New Orleans is replacing utility poles with more wind-resistant poles and selectively moving some lines underground in high-risk areas. The first phase through 2026 covers about 63 miles of power lines at a cost of $100 million. The Federal Energy Regulatory Commission requires transmission providers to report risk assessments, operational impacts, and mitigation plans for extreme heat and cold. Power sharing is constrained by federal reserve requirements that limit usable surplus to electricity above a safety threshold. Transfers must be arranged before blackouts, including identifying sending sources, available lines, and actions to prevent overloads elsewhere.
