September 10, 2025 — Tesla has unveiled the Megapack 3, a next-generation energy storage system designed to revive its struggling storage division. The new unit offers roughly 1 megawatt-hour more capacity than the previous version and promises a significantly longer operational lifespan.
The Megapack 3 is aimed at utilities, renewable energy providers, and data center developers, sectors that are increasingly looking for reliable large-scale storage solutions. Tesla says the upgraded system will help meet rising demand for grid stabilization and sustainable energy integration.
Industry analysts view the move as a strategic step for Tesla, which has seen declining revenue in its energy storage segment over the past year. By enhancing performance and durability, the company hopes to regain market share and strengthen its position against competitors in the fast-growing battery storage market.
