Tesla Energy has reached a major milestone in Australia, delivering 224 Megapacks for the Orana Battery Energy Storage System (BESS) near Wellington, New South Wales. That marks the halfway point for the project, which will eventually see 448 Megapacks installed with a total capacity of 415 MW and four hours, or 1,660 MWh, of storage (via EcoGeneration).
Once complete, Orana BESS will rank among the largest energy storage facilities in the state. The project is being managed by Tesla Energy and Consolidated Power Projects, with developer Akaysha Energy noting that deliveries and installations so far have been “smooth and safe.”
Construction is already underway on the 2 km² site, located in the Central West Orana Renewable Energy Zone (REZ). The zone is expected to host up to 3,000 MW of new wind and solar generation, making large-scale storage projects like Orana BESS critical for grid reliability. The site’s proximity to a robust section of the TransGrid 330 kV transmission system, along with its shared boundary with an existing substation, also helps minimize additional infrastructure requirements.
Tesla’s Megapack is the company’s flagship utility-grade energy storage solution, designed for grid-scale applications. Each unit can store massive amounts of energy and dispatch it when needed, helping utilities smooth out demand and integrate renewable power sources into the grid. The technology has quickly become a cornerstone of large-scale battery projects worldwide.
Australia continues to be a key market for Tesla Energy. Just last month, Tesla Megapacks powered the completion of the 2.2 GWh Collie BESS, among the country’s largest to date. Earlier in September, the company deployed its first Shanghai-built Megapacks at a $285 million Australian battery project. What’s more, Tesla recently unveiled the Megapack 3, a next-generation product with 5 MWh of usable AC energy per unit and a redesigned architecture for faster installation and improved long-term efficiency.
With Orana BESS now at its halfway mark, Tesla’s Megapacks are set to play an increasingly central role in supporting New South Wales’ transition to renewable energy.
