A new investigation by Brookfield Energy Australia (Brookfield) could pave the way for the new Huntlee residential development in the NSW Hunter Valley to be built off-the-grid and powered by renewable energy.

The $1.1 million initial study is receiving $442,000 from the Australian Renewable Energy Agency (ARENA). Huntlee, developed by LWP Property Group, will be the first new town in the Hunter Valley in 50 years and will house 20,000 new residents in 7,500 homes.

ARENA CEO Ivor Frischknecht said substantial connection costs and the falling cost of renewable energy made it a good time to explore the option of forgoing grid connection.

“If this latest work shows renewables, battery storage and enabling technologies can reliably and cost effectively power new suburbs, it could set a precedent for residential developments and potentially accelerate the uptake of renewables in Australia,” Mr Frischknecht said.

“There are a number of regulatory challenges and constraints and technical risks facing microgrids. Brookfield will share key insights about overcoming these barriers with the energy industry.”

Brookfield Energy CEO Richie Sheather welcomed today’s announcement.

“We are excited to be exploring sustainable alternative solutions for energy and water infrastructure solutions and see an emerging competitive market for large-scale local microgrids leveraging high penetration renewable,” Mr Sheather said.

Flow Systems, a Brookfield company, is spearheading Brookfield’s sustainable multi-utility initiative across Australia.

“Our goal is to develop a model that has 10 times the penetration of renewables for the equivalent cost of energy. Proving this can be done technically and commercially will be a real step change for embedded renewables in this country,” Flow Systems Managing Director Terry Leckie said.

Huntlee Project Director Stephen Thompson said Huntlee would be an entirely master-planned community designed for 21st Century living and embracing the very latest in renewables would be a key factor in ensuring the town’s prosperous future.

“For quite a number of years, we have been investigating ways to incorporate cutting-edge renewable technology into the very fabric of the town,” Mr Thompson said.

“We’re excited by the possibility of developing Australia’s first town-scale greenfield microgrid and all of the advantages that level of innovation would bring to our residents and
commercial operators.

“If the proposed model for Huntlee is successful, it will positively influence the nature of housing, employment, business, transportation and education for our future residents.

“The Huntlee team welcomes the opportunity to work with Brookfield Energy Australia and Flow Systems on delivering an entirely new model for off-grid living in Australia, made possible with support from ARENA.”
