Tesla Deploys 13.5 GWh of Energy Storage in the Second Quarter of 2026
Tesla said on 2 July that it deployed 13.5 GWh of energy storage in the second quarter of 2026. That is up from 8.8 GWh in the first quarter and 9.6 GWh a year earlier, and the company's second-best quarter on record.
The numbers
Tesla's production, deliveries and deployments release gives the 13.5 GWh figure. ESS News adds the comparisons: 53% more than the 8.8 GWh of Q1 2026, 40% more than the 9.6 GWh of Q2 2025, and just under the 14.2 GWh of Q4 2025, which remains the record.
The same report says cumulative deployments are more than 132 GWh since 2016, and that Tesla said on its first-quarter call that 2026 would exceed 2025. ESS News says the current pace is on track for that, which is the publication's reading rather than a Tesla statement in this release.
What the figure does not tell you
Tesla's release refers only to energy storage products. It does not say how much of the 13.5 GWh is Megapack, the large grid and commercial product, and how much is Powerwall, the home battery. We could not find a split, so this number is not a measure of home battery sales.
Tesla also notes that deliveries and deployments are only two measures of its financial performance and should not be treated as an indicator of quarterly results. It has said it will report earnings on 22 July.
Why home battery buyers might care
A large and growing storage business helps Tesla scale production of cells and software, but that does not tell you whether a particular home battery suits your house. Size, power rating, warranty and installer quality matter more. Our Tesla brand page lists the products we cover, and the home battery storage section compares installed systems side by side.
If you are weighing up capacity, start from your own usage with the home battery calculator rather than from a manufacturer's headline volume.
