What FERC Does and Why Planning Was Broken

To understand where transmission policy is heading, you first have to understand the agency at its center and the specific way its old rules failed. The Federal Energy Regulatory Commission — FERC — is the independent federal body that oversees the interstate transmission of electricity, the wholesale power markets, and the rates and terms on which the high-voltage grid operates. It does not build lines and it does not, by itself, site them; its power is to set the rules that the transmission owners and regional operators must follow, and to approve or reject the rates and cost-allocation methods they propose. That regulatory perch, over the wires that cross state lines, is why FERC sits at the heart of this whole story.

The jurisdictional split matters, because it explains a chronic weakness. FERC governs the interstate wholesale grid, but the physical siting and permitting of most transmission lines has traditionally rested with the states. So FERC can shape how lines are planned and paid for, yet a line still has to win approval from each state it crosses. That division is the seam through which many interstate projects have fallen: FERC could bless the economics, but any state along the route could still refuse to host the towers. Reform has had to work within, and around, that seam ever since.

Now the deeper failure. For most of its modern history, transmission planning was reactive and piecemeal. Utilities and regional operators planned mainly to fix identified reliability problems and to connect specific generators as they showed up in the queue. There was very little forward-looking, region-wide planning for the transmission that a changing fleet and a growing set of large loads would obviously need over the coming decades. Because nobody planned proactively for the big regional backbone, the grid grew a piece at a time, project by project, each justified narrowly. The result was a network optimized for yesterday's flows and badly short of the long-haul capacity tomorrow required.

FERC's earlier reform, Order 1000, tried to push regions toward more coordinated, cost-conscious planning and to open transmission development to competition. It was a genuine step, but it left the core problem largely intact: planning still tended to be near-term, reliability-driven, and reluctant to look decades ahead or to weigh the broad economic benefits a large line delivers. Regions could, and often did, avoid planning the very backbone that would relieve the congestion strangling their queues. The interconnection process, meanwhile, kept assigning individual projects the cost of network upgrades that were really regional in nature — a symptom of the same failure to plan the backbone collectively.

The empirical picture that built up over the 2010s and early 2020s was stark. Queues swelled with generation that could not connect because the transmission was not there. Congestion costs — the extra money spent running expensive local plants because cheaper distant power could not get through — mounted. Regions repeatedly built small, local fixes when a larger, forward-looking line would have solved several problems at once, more cheaply per unit of benefit. Analysts kept pointing to the same gap: no one was required to plan for the long term and across a wide enough region, and no one had a fair, durable way to spread the cost of the big lines that long-term planning would call for.

For an investor, this history is the reason to read regulatory posture as a hard variable, not background noise. A region's planning philosophy — whether it plans the backbone ahead of need or waits for problems to force its hand — directly shapes how long your load will wait and how much upgrade cost it will absorb. For an operator, the takeaway is that the interconnection pain you feel is downstream of a planning failure decided years earlier and far above your project. And for the policy reader, this is the essential setup: FERC diagnosed that the missing ingredient was long-term, regional, proactive planning with a fair way to pay for it. That diagnosis is exactly what the next lesson's reform tries to institutionalize — turning transmission planning from a reactive patchwork into a deliberate, forward-looking discipline. You cannot appreciate why that reform matters until you have felt the weight of the problem it was written to solve.
