Summary

TransGrid will build, test and operate a 50 MW / 75 MWh lithium-ion battery at the Wallgrove substation in western Sydney. The project will use Tesla batteries and demonstrate its innovative synthetic inertia product known as “Virtual Machine Mode”. TransGrid has entered into an agreement with Infigen for use of the 50MW / 75MWh battery for market services.

Need

As part of the TransGrid Wallgrove Battery project, TransGrid has identified a likely inertia shortfall for NSW during the period 2023-24 to 2027-28, due to the expected closure of Liddell and Vales Point power stations. TransGrid is responsible for resolving these inertia shortfalls in NSW and will use the project to demonstrate the ability of battery technology with synthetic inertia and fast frequency response capability to provide inertia services.

Action

The TransGrid Wallgrove Battery project will be equipped with synthetic inertia and fast frequency response capabilities. TransGrid will also complete modelling and monitoring of the project’s response during grid disturbances to better understand the technology’s capability and its impact on the NSW power system.

Outcome

The key objective is to demonstrate the technical capability of batteries with advanced inverter capabilities to replace traditional inertia and, in doing so, demonstrate that batteries can provide the most cost effective solution for NSW’s upcoming inertia shortfall.
