GMA Garnet's mine get's ARENA green light for Microgrid

Garnet deal

At Port Gregory in the Mid West, Advanced Energy Resources are working on an $11.2 million microgrid to supply GMA Garnet's nearby mine.

Arena announced today it would chip in $3 million.

The project will include a 2.5MW wind farm, 1MW solar farm and a 2MW/0.5MWh battery.

It will provide up to 70 per cent of the mine's power needs.

Arena chief executive Darren Miller said customers at the fringe of power grids often suffered network outages, so microgrids with batteries could improve reliability.

Arena will be using refurbished wind turbines that had formerly operated in Germany.

"In Europe, there is a significant market for refurbished wind turbines, as wind farms increase their capacity by upgrading smaller turbines for larger, more powerful ones," Mr Miller said.

"Now, AER has brought experience from the European market to enable them to give these turbines a second life in Western Australia,.

"This grid connection design will overcome challenges associated with connections to weak grids, providing backup power, and facilitating high penetrations of customer-side renewable generation.

"Effectively, this approach allows the solar and wind to operate in a microgrid with the battery and inverters, which avoided the need to upgrade the network."
