How much announced capacity is actually blocked — not how many ordinances exist. Only restrictions that genuinely bind (conditional and above) and are in force right now count toward the figure, and each project is counted once at its largest affected capacity.

Why the two counts differ — 26 restrictions are in force, but 5 of them are advisory, proposed or merely procedural: they add process and cost without stopping a project. A tracker that counts ordinances reports the larger number. This page reports the megawatts. Among the 30 tracked restrictions that reached a decision, 100% were adopted (0 rejected, 4still pending). This is the tracker's sample, not the universe of siting decisions — measures that never attracted coverage are not in it.
MW at risk
Restrictions bite through the interconnection queue, so the RTO view is the one that maps to transmission exposure.

Restrictions are linked to projects explicitly by an analyst, never inferred from matching location text. A wrong inference would silently move the headline figure, which is the one number this page exists to produce.

An expiry is a positive catalyst — capacity returning to the pipeline — and nobody publishes a list of them. A time-limited ban with no published end date is shown as such rather than being treated as indefinite.
