Tesla has packaged four Megapack 3 units, a transformer and switchgear into a factory-built “Megablock.” The promise: faster interconnects, denser sites and materially lower on-site construction. If it works, grid batteries start to look less like bespoke projects and more like plug-and-play infrastructure.
The news, stripped to essentials
At RE+ in Las Vegas, Tesla unveiled Megablock, a pre-engineered 20 MWh building block that combines four Megapack 3 units with a site transformer and switchgear. Tesla says the configuration enables 23% faster installation with up to 40% lower construction costs versus today’s practice of wiring packs to field-installed balance-of-plant.
