Tesla Energy, in brief.
Storage, solar, and Autobidder: Tesla's margin-rich energy segment
Tesla Energy is a second growth engine that sells batteries at scale, earns roughly 30% gross margin above the car business, and layers software on top.
- Storage deployments grew about 12x in four years, to a record 46.7 GWh in 2025.
- FY2025 energy revenue was $12.77B, up 27% year over year, at roughly 30% gross margin.
- That margin beats automotive's roughly 17.9% ex-credits, so energy growth lifts the blended margin.
- The main risks are commoditizing hardware, cell-supply limits, and thin disclosure on recurring software revenue.
