Defensible NEM analyticsfor investment and asset management

An energy research and analytics platform connecting market data with power flow, dispatch and commercial modelling. Understand what happened, why it happened, and how different scenarios could change the outcome.

Book a demoSee who it's for

Every five minutes of the market, live and through its history on one clock, and every number with its date.Real figures from 11 and 12 October 2026. The battery is modelled.

Power system and market modelling tools.

Dispatch and power flow models of the NEM, run in the cloud with the market and the network already built in. They work alongside PSS/E and PLEXOS, not instead of them. Screen projects before the connection studies start, and once a project is operational, test what network changes or an expansion would do to it.

Modelling

Dispatch

The NEM's five minute dispatch, rerun from AEMO's demand and constraint equations.

Change one thing, such as adding a battery or retiring a unit, and see what it does to prices, dispatch, curtailment and revenue, down to the constraint that bound.

Power flowBeta

A power flow (or load flow) across the transmission network, with every line, transformer and yard as it stood on the day.

Much of it has no published flow. The model gives every line and transformer a flow, so you see what is loading up early enough to change the plan, and it is being built to give Dispatch limits where none exist yet.

One platform, from power flow modelling to commercial analysis.

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.

Energy decisions are only as good as the information behind them.

supagrid brings together market data, power system modelling and commercial analysis to make complex questions easier to investigate, outcomes easier to understand and decisions easier to defend.

  • Faster analysis

    Investigate market outcomes, test scenarios and reach a conclusion with less time spent collecting data, building models and joining the dots.

  • The whole system, connected

    Understand how generators, networks, dispatch, constraints and prices interact, and how those relationships shape the outcomes that matter.

  • Analysis you can stand behind

    Trace results back to their underlying data, understand the methodology and test insights against historical market outcomes.

Research into the data, dynamics and decisions shaping the NEM.
