Western Australian (WA) renewable energy company Border Energy has made its final technology choice for the Waroona Renewable Energy Project Stage One, increasing the capacity of its 80MW battery component by 12% to 4.5 hours, compared to the originally planned four hours of storage.
The project near Parth includes a 120 MW solar park. The developer expects that the increased on-site battery capacity will allow for additional storage of electricity during times of low prices, and transmission during times of peak prices, which will benefit the economics of the project.
Frontier Energy CEO Adam Kiley said the company is in the fortunate position that the costs of its two largest capital assets, solar panels and lithium iron phosphate (LFP) batterieshave fallen significantly since the release of the project’s first definitive feasibility study (DFS) in February, which estimated costs at $118.5 million.
“Battery prices have fallen due to a combination of factors, including falling commodity prices, improving supply chains and reportedly weaker than expected demand, resulting in an ample supply of batteries in the current market,” he said.
“This unique situation is to Frontier’s advantage, with improved battery capacity resulting in longer life, approximately 4.5 hours compared to 4 hours in the DFS, increasing Waroona’s revenue while achieving lower capital costs.”
