The U.S. power grid isn’t one big machine — it’s three. That’s a problem for blackout season
The U.S. power grid is divided into three independent interconnections, limiting the ability to transfer electricity between regions during emergencies. This structural issue was highlighted during the 2021 Texas blackout, where limited import capacity exacerbated the crisis. Proposals like the Southern Spirit Transmission project aim to increase inter-regional connectivity, potentially reducing power losses. Additionally, hardening existing transmission infrastructure against extreme weather is crucial for maintaining power supply during disasters. AI
