Construction has commenced at Neoen’s Muchea Battery in Western Australia—the first 6-hour long-duration storage asset in the renewable energy giant’s global portfolio.
Located approximately 2km north of the town of Muchea, the battery will be a standalone asset with a capacity of 164MW/905MWh, connecting to Western Power’s network via the adjacent Muchea substation.

The 6-hour battery will provide essential peak demand energy capacity along with grid stability and reliability services.
Contractor UGL completed early works, including a 1.3km access road upgrade and establishment of the main laydown area, before the end of 2025, delivering reliable site access and an efficient start to construction.
UGL project manager Sandeep Kamath said, “Muchea is an important project for the state, our client, and our partners. From day one we have focused on building a strong safety culture, working closely with stakeholders and delivering high-quality outcomes.
“This project shows what can be achieved through planning, teamwork and a shared commitment to excellence.”
Over the coming months, the team will complete major civil activities and prepare for the arrival of Tesla Megapacks and associated infrastructure, positioning the project for a smooth installation and commissioning phase.
