The company will spend $7.5 million building and installing a 2MW solar PV array and a 2MW/0.5MWh battery to store energy.
The new features will be integrated with Carnegie’s CETO 6 wave technology which uses wave action to drive turbines and create electricity.
The Australian Renewable Energy Agency will kick in $2.5 million and construction will start by the end of the year.
The company is aiming to start commissioning in the first half of next year.
“The Garden Island Microgrid Project will be the first time anywhere in the world that wave energy will be combined with solar and batteries in a microgrid configuration,” Carnegie’s managing director and chief executive Michael Ottaviano said.
“The demonstration of this microgrid project will help drive the commercialisation of CETO and will be a model we will roll out to island nations around the world.
“Island nations are desperate for an energy innovation to replace their current reliance on electricity generated using imported fossil fuels, which is extremely expensive and has a large environmental footprint.
“Now Carnegie presents an effective green alternative, with the GIMG project acting as a template for remote island and grid communities globally.”
Carnegie’s CETO technology is different from other wave energy devices as it operates under water.
