supagridNEM analysis and modelling in one workspace.
supagrid combines rigorous research, sophisticated modelling and connected market data to produce reliable, actionable intelligence on Australia's electricity market.
Illustrative numbers
From power flow modelling to commercial analysis.
Each part stands on its own, and all of them work together on one map.
The map
Every unit, line, substation, constraint and outage on one dated map, with history and live on one clock.
Modelling
Dispatch, load and power flow modelling, connected to commercial outcomes. Reconstruct past market conditions, introduce a new project or retire a generating unit, and assess the impact on dispatch, prices and project economics. Models tested against historical market outcomes.

One price spike, through every part of supagrid.
Thursday 13 August 2026. South Australia's price jumps at 18:35 Brisbane (08:35 UTC), and each part of supagrid answers a piece of the question.

Hear it first
At 17:55 an alert lands. VIC–SA has reached its 650 MW import limit, 40 minutes before South Australia's price moves.

See it on the map
At 18:35 SA's price jumps from $86.00 to $1,240.00/MWh while Victoria's holds at $84.00. The map shows why. The link between them is full.

Ask why
Ask the Analyst. It reads the link, the price and the offers, and shows its working. The SA gas peaker, at 142 of its 150 MW, set the price.
The Analyst - 04
Test a change
Rerun the evening with a 150 MW battery at Adelaide. SA's price at 18:35 would have been $410.00, and the battery would return 11.4%.

Hilltop Wind ran at 96 MW through the spike. Step back to the year, and Benchmarking ranks it third on revenue per MW against the wind farms most like it.

- Power flow and line ratings
- The flow on every line against its rating, now and through history.
- The schematic
- Single line diagrams of the network.
- Curtailment on the map
- A ring around each curtailed unit, showing the share of output it lost.
Modelling
- Test a change
- Rerun a past market with a project added, or a unit retired or derated, batteries included.
- The Backcast
- The model rerunning the real market, so you can see how close it gets.

One set of data under every part.
A number means the same thing wherever you meet it, and you can always see where it came from.
A source on every number
Every figure says in words where it came from and when, whether Published straight from the source, Derived by a fixed formula, or Modelled.
The network as it stood
The map holds the network as it stood on each day, so a past evening reads as it was, not as the grid is now.
Tested against history
Before you trust a scenario, the Backcast replays the real market so you can judge how close the model gets. Accuracy is published after a test on data the model hasn't seen.
