EA NSW residual-load merit heuristic v0.1.0
Limitations
No bid stack, no unit availability, no interconnectors, no kgCO2e marginal factor. Research/model-development only.

Why this model?

NEM NSW is the first modelling pilot because EnergyAsia already maintains a live NSW region, annual intensity observations, and a clear residual-load question. The model is disposable. The trusted representation of the NSW system is the asset.

Assumptions

  • NSW NEM region residual demand is typically met first by near-zero short-run-cost renewables, then by scheduled thermal plant.
  • Black coal is the dominant scheduled thermal fleet in the NSW NEM region.
  • Gas plant is more likely to be on or near the margin at high residual demand, especially the evening peak.
  • Rooftop and utility solar are treated as inframarginal while generating.
  • Wind is treated as inframarginal when generating.
  • Hydro, batteries, and interconnectors are unresolved in v0.1.
