By now, it’s fairly well understood that the US badly needs more electricity transmission lines to keep up with the changing generation mix and growth in demand that will come with clean electrification. But new lines, especially the much-needed longer-distance regional lines, are being built at a snail’s pace. If the US is to hit its mid-century climate goals, transmission capacity expansion must radically accelerate.

Congress helped a little with money in the infrastructure bill, and the Biden administration helped by establishing a Grid Deployment Office inside the Department of Energy, but arguably the biggest opportunity for progress comes in the form of an upcoming rule by the Federal Energy Regulatory Commission (FERC).

It will beef up the commission’s existing rules on regional transmission planning, but exactly how much it will strengthen them depends on the final rule, expected early next year. Transmission advocates are urging FERC to pass a rule with reel teeth — including Senate Majority Leader Chuck Schumer, who sent the commission a letter with encouragement and suggestions in July.

Nobody knows more about grid policy than Rob Gramlich, founder and president of Grid Strategies, a policy analysis and strategy firm. He is executive director of both Americans for a Clean Energy Grid and the WATT Coalition, serves as a board advisor to a half-dozen other groups, and has a long history in the industry, including a stint at FERC in the early 2000s.

I talked with Rob about the current state of affairs in transmission policy, the scope of FERC’s authority, and the details that matter in the coming rule. Don’t let the technical-sounding subject scare you off — this was a fun one, and incredibly clarifying.
