Renewable power producer Vena Energy Australia will soon begin construction of Queensland’s largest grid-scale battery near Wandoan in the Western Downs. Vena Energy’s Battery Energy Storage System (BESS) will have an initial capacity of 100MW and store 150MWh of energy, which could power up to 57,000 average homes annually.

Vena Energy Australia will build, own and maintain the BESS while energy retailer AGL will have full operational dispatch rights under a 15-year agreement between the two companies.

The BESS is the first construction milestone of Veda’s Wandoan South Project, approved to generate up to 1GW of solar electricity and 450MW of energy storage, to be developed across several stages.

“The BESS will encourage a positive investment environment for future projects as well as encourage broader adoption of renewable energy in Queensland and in Australia,” Vena Energy CEO Nitin Apte said of the $120 million project.

AGL CEO Brett Redman said the agreement was consistent with AGL’s strategy of developing and/or contracting flexible storage and generation to support the transition from coal generation to renewables.

“The battery will enable AGL to leverage excess solar generation in Queensland and provide capacity when the Coopers Gap Wind Farm and other renewable power sources are not generating,” Redman said.

Head of Vena Energy Australia Anil Nangia said local employment and procurement opportunities would be established throughout the 12-month construction program.

“We plan to significantly invest in the local region, with local purchasing likely to include a wide range of products and services from fencing contractors, concreters, welders, electricians, plant and equipment operators, transport contractors and administrators,” Nangia said.

Vena Energy is also advancing plans for a $650 million solar project at the site, as part of the Wandoan South Project.

In Australia, Vena Energy is progressing over 2.5GW of renewable energy projects across the country and last year commissioned a 95MW solar project at Tailem Bend in South Australia.

Vena Energy Australia is the Australian arm of Singapore-headquartered Vena Energy, which oversees more than 11GW of clean energy assets in operation, construction and development.
