Probabilistic Boundary Assessment.
The maximum megawatts you can push across each boundary — under every credible N-1.
PBA walks transfer up until the first contingency binds, with quad-boosters and HVDCs optimally re-dispatched at every step. The output is a defensible, industry-standard transfer capability per boundary.
Why it matters now With a record build-out queuing behind the same transmission corridors, the first question on any connection is no longer whether the plant works — it's how much the boundary can carry before it has to be reinforced. Price that wrong and the offer is either undeliverable or needlessly capped. PBA finds the true transfer limit, contingency by contingency.
Industry context, 2025 — IEA, Ember, market forecasts and a 2025 survey of 100+ energy professionals.
Transfer capability — base vs asset-optimised.
Each boundary's secure transfer limit, before and after optimal dispatch of quad-boosters and HVDCs. Hover a bar for the binding detail.
How a defensible transfer figure is built.
Boundary definition
Zone-to-zone map, monitored circuits and the monitored contingency set per boundary.
Step transfer up
Transfer is walked up incrementally until the first credible N-1 contingency binds.
Asset optimisation
Nearby quad-boosters and HVDC set-points are optimally re-dispatched at every step.
Capability output
The secure capability at first binding — base and optimised — with the binding contingency tagged.
Boundary D is the bottleneck — optimisation lifts it +21% but it still misses the planning target. PBA quantifies exactly the gap the next reinforcement, HVDC bootstrap or storage must close.
