Construction begins on Garden Island microgrid in WA


Construction has commenced on an integrated solar and battery storage microgrid at Garden Island in Western Australia.

Carnegie Clean Energy will build the 2MW solar and 0.5MWh battery storage system, which is expected to be the largest embedded, grid-connected solar and battery microgrid in Australia.

The WA Garden Island facility, in conjunction with the desalination plant already built by Carnegie on the island, will supply power and water to the HMAS Stirling naval base, which is the largest of its kind in Australia.

“We are delighted to have Minister Frydenberg present to officially break ground on the Garden Island Microgrid,” Carnegie managing director and CEO Dr Michael Ottaviano said.

“Carnegie Clean Energy is at the forefront in the design and delivery of renewable microgrid solutions that are revolutionary.

“Carnegie and Energy Made Clean have a strong track record in renewable and microgrid solutions like the Garden Island Microgrid at HMAS Stirling, the recently won microgrid at the Delamere weapons range base in the Northern Territory and previously for the Department of Defence on Bathurst Island in the Northern Territory.

“Renewable microgrids can deliver improved security of supply with clean, reliable power and water.”

The project received $28.5 million of combined grant funding from the Australian Renewable Energy Agency (ARENA).

“Carnegie are pioneers in the renewable energy industry,” Federal Energy Minister Josh Frydenberg said.

“Their 240kW CETO 5 wave energy units, built and operated on Garden Island between 2012 and 2016, was the world’s first commercial-scale wave array to be connected to a grid.”

Mr Frydenberg said the project would integrate with the existing Defence power infrastructure to increase the energy resilience of the base.

The potential remains for the microgrid to be connected to a wave energy resource in the future

“The government continues to support the work of Carnegie and we look forward to seeing how this project will inform Carnegie’s ability to provide energy security solutions at island locations in the future,” Mr Frydenberg said.
