March 13, 2025: Investment firm Quinbrook Infrastructure Partners said on March 5 it was working with China’s CATL on an eight-hour capacity BESS.

Quinbrook said technical collaboration on the advanced long duration energy storage system would aim to deploy a combined total of more than 3 GW of BESS sites across Australia, targeting existing partners and new commercial and industrial customers.
Quinbrook said the move would go beyond solar-BESS facilities it has already built in the US and UK that have four hours of battery storage.

Projects in high year-round solar locations can already produce power for up to 14 hours a day, the company said. Doubling the storage duration improves cost competitiveness to a significant degree.

The first sites planned to host the new BESS systems include Quinbrook’s Supernode site in Brisbane, which is already home to Australia’s largest BESS campus.

Quinbrook has collectively invested around US$7 billion of equity capital in 40GW of energy infrastructure assets to date, representing a total transaction value of nearly $30 billion.

Tan Libin, CATL’s chief customer officer, said: “By combining our cutting-edge battery technology with Quinbrook’s vision for a cleaner future, we aim to accelerate the global transition to reliable, low-carbon power and contribute to a more sustainable world.”
