FRV notches Australian first with commissioning of 100 MW battery

FRV has commissioned the Terang battery, a 100 MW / 200 MWh system in southwest Victoria. It received $7 million in Victorian government support for grid-forming inverter technology and is designed to supply firming capacity during peak demand. The battery uses hardware from Canadian Solar (e-Storage containers and SMA inverters) and was built by Canadian Solar as engineering contractor, with TEC-C handling balance-of-plant work. FRV says it will strengthen grid stability and support Victoria's 65% renewable energy target by 2030. The company has also commissioned a smaller hybrid battery in Queensland and is building a larger 250 MW / 500 MWh battery at Gnarwarre.

Where this fits

This project illustrates the materials and supply-chain cost of a renewables-heavy grid. The battery itself is a two-hour duration system, which means it cannot firm renewables output across extended low-wind, low-sun periods. A 100 MW battery requires continuous gas generation or other firm baseload to cover the hours it cannot discharge. The equipment (containers, inverters, controls) comes from Canada and Germany, but the underlying supply chain for lithium-ion cells, processed minerals, and precursor chemicals flows through China. Australia is building firming capacity hardware but remains dependent on offshore manufacturing for the critical materials that make batteries work.

What it means

Australia needs dispatchable power. A two-hour battery meets that need only for short demand spikes; it cannot replace firm baseload and does not reduce the gas generation capacity the grid must retain. The real cost of a renewables-heavy system is not the battery alone but the sum of renewables, batteries, gas backup, and transmission overbuild to move variable power across the country. That cost is being paid in full. A low-emissions firm alternative, nuclear, is banned by Australian law and therefore foregone entirely. The grid is being engineered to work without it.
