Construction of the 50MW/200MWh grid-scale battery is expected to begin before the end of the year, with plans to be operational in 2020.

Pangea Energy is part of Sen Tek Energy Solutions, a multinational renewable energy project developer in South East Asia. It signed the letter of intent with Canadian energy storage systems manufacturer CellCube this week.

Developed across 79ha in Port Augusta, the US$200 million (AU$290 million) into the project is the latest in a string of solar and wind farms proposed to be built in South Australia’s Mid North.

CellCube develops, manufactures, and markets its vanadium redox flow technology energy storage systems, which it says can maintain 99 per cent residual energy capacity after 11,000 cycles.

CellCube CEO Stefan Schauss said the battery would offer multiple grid services such as voltage compensation, reactive power and frequency regulation services and renewable baseload to the Australian market alongside a planned 50MW solar project on the same site.

He said the project was a wonderful example of how renewable energy generation and “safe, reliable and sustainable energy storage technology such as the vanadium redox-flow battery” can provide renewable baseload energy.

“Our new high performing CellCube is three times more efficient than any power-2-X or hydrogen technology which will not be available at this scale in the next three years,” Schauss said.

“CellCube also offers a lifetime support of 25 years with no degradation or augmentation like needed for lithium. This is real true value for money.”

The town of Port Augusta has a population of 6500 and is located about 300km north of Adelaide, the South Australian capital.

The closure of the 784MW coal-fired Port Augusta power stations in 2016 signalled an …
