The federal government adopted new rules Monday requiring electric utilities to be more transparent and proactive in planning the huge transmission lines that send power across their territories.
Transmission is considered key to adding more renewable energy to the grid as fossil fuel-powered generation, particularly coal, is retired over the next decade. Stronger transmission across regions would also make the U.S. power supply more resilient to extreme temperatures and natural disasters, which scientists say are becoming more destructive as a result of climate change.
The rules, issued by the Federal Energy Regulatory Commission (FERC), do not mandate construction of any new transmission infrastructure. They require utilities to publish regional plans that look 20 years ahead and respond to specific criteria, including the projected generation mix and corporate clean energy commitments.
They also allow the federal government to grant permits for new transmission in high-priority corridors if states do not.
The new rules follow a tightening of air pollution standards for power plants that provide electricity, a move observers say will accelerate the retirement of coal plants and make gas more difficult to pursue, thus boosting demand for renewables. Those new emissions rules, however, are being challenged in court.
Nick Guidi, a senior attorney with the Southern Environmental Law Center who works on energy regulation, said the new FERC transmission rules bring much needed transparency and rigor to the existing planning process, which has been in place for over a decade and failed to produce much in the way of results, particularly in the South.
