NSW to deploy 1MW BESS to defer infrastructure costs and support grid service

West Dapto, NSW, Australia

Endeavour Energy, a power distribution company in Australia, announced on October 12 that it had awarded renewables integration firm MPower the contract to supply and install a 1MWh battery energy storage system to support New South Wales’ grid at West Dapto.

The trial will allow the New South Wales-based company to reduce network investment by up to AS$1 million ($780,000) per year to keep downward pressure on its network charges, and if successful could be deployed to defer the construction of up to four new zone substations by 2024.

MPower will design, build and install the BESS at the site of Endeavour Energy’s future West Dapto zone substation and hopes to be operational by next summer.

The announcement comes as distribution network operators rethink the way they connect customers and communities to the grid as end users embrace new technologies such as solar and battery storage.

Endeavour Energy’s general manager asset management, Ty Christopher, said the project was an important milestone in adapting its network to meet the future energy needs of our customers.

Christopher said: “The experience gained from this trial will help us build and operate a secure, reliable and affordable network in the future. Battery storage systems have significant potential to reduce network capital costs, help manage load growth, peak demand, power quality and supply interruptions.

“This trial will allow Endeavour Energy to quantify the benefits of battery storage in a real, grid-scale setting and provide us the expertise to utilise this technology as future needs arise.”

Anthony Csillag, managing director of MPower Projects said: “There is widespread publicity about energy storage utilising batteries. This project is a shining example of how energy storage can be used for a critical application. It adds a new era technology into the grid that performs like other generators on the network, particularly in relation to network control and protection.

“The system will also resynchronize to the grid seamlessly to transition from islanded operation to grid connected operation.”
