Capacity Expansion Demo
Interactive results from a 523-bus ISO New England planning study
A capacity expansion study you can interrogate
Most planning studies arrive as a PDF and a spreadsheet. This one is a live model of a real system — an ISO New England footprint reduced to 523 buses — where every result can be traced back to the assumptions that produced it.
Full-factorial scenario matrix
Load, renewable siting, and carbon target varied independently — every combination solved to optimality, not a handful of hand-picked cases.
Nodal network visualisation
Reduced and full network overlays on real geography, with transmission corridors routed along physical paths rather than drawn as straight lines.
Side-by-side comparison
Any two scenarios diffed across cost, capacity mix, dispatch, and transmission build — with the drivers surfaced, not just the deltas.
Cost decomposition
Investment, fixed and variable O&M, fuel, carbon, and unserved energy separated so the tradeoff behind a number is visible.
Reliability diagnostics
Load shedding traced to its cause — distinguishing genuine supply shortfall from deliverability limits imposed by siting and network constraints.
Hourly dispatch
Chronological dispatch by technology across representative periods, so the capacity mix can be checked against how it actually operates.
