The Federal Energy Regulatory Commission (FERC) has finalized a rule to overhaul the US electric transmission system, setting new requirements for moving electricity across states and covering the costs of new projects. The rule aims to expand electricity transmission, boost Texas wind and solar generation, and require grid planning for 20 years into the future. The overhaul limits states' authority to block long-distance power lines, enabling remote wind and solar farms. The rule is seen as a move to accelerate clean power and expand transmission infrastructure to meet surging demand fueled by various factors like data centers, electrification, and artificial intelligence.
