According to Sawyer Merritt on Twitter, Neoen Australia has started construction on a $220 million big battery project, marking the world’s first deployment of Tesla’s new Megablock—a next-generation grid-scale battery system. The Megablock integrates four Megapack 3 units into a single plug-and-play 20 MWh block, each with its own transformer and switchgear. Tesla claims this system will enable 23% faster installations and up to 40% lower construction costs for utility-scale energy storage solutions. The Megablock features advanced software, hardware, and service integration, maximizing efficiency and reducing above-ground cabling. Production of Megapack 3 is set to begin at Tesla’s Houston Megafactory in 2026, targeting up to 50 GWh annual capacity. This development signals significant business opportunities for AI-driven energy management, predictive maintenance, and grid optimization platforms, as the rapid deployment and cost-effectiveness of such scalable storage solutions drive market demand for intelligent energy analytics and automation tools.
