Tesla today released its second-quarter 2026 global energy storage deployment figures, reporting 13.5 GWh of storage capacity installed worldwide, marking robust sequential and year-over-year growth amid a booming U.S. energy storage market.

The Q2 2026 volume represents a 53% quarter-on-quarter jump from the 8.8 GWh deployed in Q1 2026, and a 40% year-over-year rise versus the 9.6 GWh recorded in Q2 2025. The quarter’s total stands as Tesla’s second-highest quarterly storage deployment on record, only trailing the 14.2 GWh installed in Q4 2025.

Since launching its energy storage business in 2016, Tesla has surpassed 132 GWh of cumulative global deployments. Yearly rollouts have expanded drastically from just 0.3 GWh in 2016 to a full-year record of 46.7 GWh in 2025, with 22.3 GWh already deployed through the first half of 2026. Company officials previously forecasted full-year 2026 storage volumes would outpace 2025’s performance during the Q1 earnings call, a trajectory reinforced by Q2’s strong results.

Tesla’s explosive storage growth aligns with industry-wide expansion across the United States. Joint research from the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence confirmed the U.S. energy storage sector entered an era of sustained large-scale installations, with national deployments climbing 30% year-over-year in 2025. Wood Mackenzie separately tracked 8.4 GWh of all-sector U.S. storage deployments in Q1 2026, a 41% increase against Q1 2025.

The automaker and clean energy firm also announced the schedule for its Q2 2026 financial results webcast: the live investor briefing will kick off at 5:30 p.m. Eastern Time on July 22, 2026, accessible via Tesla’s investor relations website.
