Model descriptions are published here once reviewed, with their assumptions, evidence and validation. They describe models; they are not live simulations.

Energy Nexus reviewed models are published descriptions of the models used in the energy field, with their assumptions, data, validation and limits, built on methods such as energy generation, storage and grid technology as well as power systems engineering. They describe models; they are not live simulations, and no output on them is a finding.

Where demand concentrates in cities and the rail, road and port corridors that move fuel and equipment, shown for Australia as an example geography for this subject.
| Model class | Open examples | Question it answers | Validation |
|---|---|---|---|
| Capacity expansion | PyPSA, OSeMOSYS, TIMES | Least-cost system plans under policy constraints | Benchmarks against historical build and other models |
| Production cost and unit commitment | PLEXOS-type and open equivalents | Hourly operation and adequacy | Back-casting of historical dispatch |
| Power flow and dynamics | pandapower, PSS-type tools | Stability under disturbances | Comparison with recorded events |
| Gas network models | Open gas flow tools | Pipeline capacity in cold spells | Historical flow reconstruction |
Open models are preferred so that results can be reproduced; any proprietary model is named with its version.
Analysis runs in Nexus Foundry; reviewed releases are listed here.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Model validation | Comparing model predictions with independent observations to judge fitness for a stated use. |
| Model card | A short document describing a model's intended use, training data, performance and limits. |
| Uncertainty quantification | Characterising and propagating the uncertainties in a model to state confidence in its outputs. |
| Surrogate model | A fast statistical model trained to approximate a slow simulation or experiment. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
