GridQube uses data on known parameters of the network, transformer set-points and outputs of power flow meters and telemetry devices, in conjunction with with statistical data about the typical network utilisation.

From these thousands of pieces of data, GridQube in near real time creates a more complete understanding of the current operational state of the network including dynamic operating envelopes, then has ever been possible before.

This creates customer benefits by increasing access to available capacity, reduced risk, enhanced network benefits and augmentation reduction.

Queensland electricity distributors Ergon Energy Network and Energex (part of Energy Queensland) have been named the 2021 Energy Network Industry Innovation Award recipient.

The winning project is an Australian-first implementation of a digital system to generate a complete and consistent picture of the operational state of the grid. This supports the integration of distributed energy resources (DER) like rooftop solar PV so more customers can export solar, voltage impacts on the grid can be mitigated and power quality can be improved. “This ground-breaking project will help Energex and Ergon deliver more for customers while reducing the network expenditure needed to manage DER impacts, improve power quality and help our transition to a decarbonised electricity system,”. “Our focus has been on increasing solar opportunities for customers while supporting the safe, reliable and equitable operation of the grid and keeping costs down,” EQL CEO Rod Duke said.
