Stanwell is working on a plan to install a large, standalone battery at Tarong Power Station to support storage of renewable energy.
The proposed 150MW Battery Energy Storage System (BESS) could be in operation as early as 2023.
Stanwell acting CEO Adam Aspinall said large-scale energy storage would play an important role in Queensland’s future as higher levels of renewable energy entered the system.
“Over 3600 MW of new large-scale energy storage will be required in Queensland over the next 20 years,” Mr Aspinall said.
“Energy storage will be critical as it helps facilitate the integration of renewable energy into the energy system by storing electricity generated by wind and solar and supplying it to the market when required.”
Mr Aspinall said Stanwell had recently completed a feasibility study and was now focussed on a more detailed assessment with a view to reaching a final investment decision later this year.
“Our feasibility study found that there were commercial opportunities in locating a large-scale energy storage system in southern Queensland,” he said.
“By locating battery storage at Tarong Power Station, we can capitalise on existing land and connection infrastructure, support the investment in renewables within the region and help maintain system security and reliability.
“The project would also provide local employment opportunities, creating 80-full time jobs over the eight-month construction phase, and six full-time jobs over the 20-year operation and maintenance phase.”
Mr Aspinall said that if the assessment results were positive, the initial 150MW battery with two hours storage could start operations in 2023.
“The opportunity to extend the battery’s storage capacity for further deployment between 2025 and 2030 would be considered at a later date,” he said.
