Tesla has announced it deployed 13.5 GWh of energy storage capacity across the globe in Q2 2026, up 53% from the 8.8 GWh the company deployed in Q1 and up 40% compared to the 9.6 GWh deployed in Q2 2025.
The Q2 deployments represent Tesla’s second-largest quarterly total to date, falling just shy of the 14.2 GWh deployed in Q4 2025.
The latest energy storage installations bring Tesla’s total deployments to more than 132 GWh since 2016, placing the company on a trajectory to exceed its 2025 deployments, as predicted by Tesla representatives in the company’s Q1 earnings call.
The immense growth in Tesla’s deployment numbers mirrors the broader U.S. energy storage market. A recent report on the outlook for the U.S. energy storage market from the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence asserted that the U.S. has entered a “new phase of sustained, high-volume deployment” in energy storage, noting a 30% year-over year increase in deployments in 2025.
For Q1, 2026, Wood Mackenzie noted a total U.S. deployment of 8.4 GWh in energy storage capacity across all sectors, a 41% increase compared to Q1 2025.
Tesla concurrently announced the date and time of its Q2 financial results webcast, which will be held at 5:30 p.m. Eastern Time on Wednesday, July 22, 2026, in a live website on the Tesla investor relations web page.
Energy storage deployment is certain to be a topic of great interest to investors on the Tesla call, along with news on the state of Elon Musk’s 100 GW solar manufacturing ambitions and an update regarding the recent agreement Tesla inked with Sunrun and Renew Home to offer 16.8 GW of flexible power output to hyperscalers and grid operators through a VPP.
