Akaysha Energy has kicked off construction at its $200 million Brendale Battery Energy Storage System (BESS), one of the largest in Queensland, which will add 205MW/410MWh of storage capacity of the National Electricity Market (NEM).
Commencing commercial operation in 2026, the Brendale BESS is expected to reduce electricity costs and enhance grid stability in line with the Queensland Government’s renewable energy targets.

Located on UnityWater’s 3.7-acre site next to the South Pine substation, the central node of Queensland’s electricity grid, the Brendale BESS will feature Tesla Megapack technology while the balance of plant will be delivered by Consolidated Power Projects Australia (CPP).
As one of Queensland’s largest batteries, the Brendale BESS can store enough energy to power up to 300,000 homes during a blackout, adding significant storage capacity to Queensland’s electricity network.

The project will provide energy arbitrage and frequency control ancillary services to support the NEM and facilitate the integration of solar and wind projects by leveraging existing transmission infrastructure in the region.
Akaysha Energy managing director and chief commercial officer Paul Curnow said, “The Brendale BESS is an important element of Akaysha Energy’s portfolio across not only Queensland but the NEM more broadly.

“The Brendale BESS is a crucial step in our mission to rapidly deploy large-scale BESS, enhancing grid stability and energy security while driving the global shift to sustainable energy.
“The Brendale BESS is one of four projects under development in the state and it’s clear that the Queensland energy sector is serious about the transition.”
