## 🎯 Key Points

- Deployed 13.7 GWh of energy storage in Q3 2026
- This is the second-largest quarterly result in company history
- The energy division consistently shows double-digit GWh volumes
- Automotive production for the same period reached 464,391 vehicles

Tesla continues to demonstrate rapid growth in its energy division, which over the past few years has transformed into a full-scale multi-gigawatt business. According to official data for the third quarter of 2026, the American manufacturer successfully deployed modern energy storage systems with a total capacity of 13.7 GWh. This result highlights sustained global demand for stationary energy storage systems, which are essential for grid balancing and the integration of renewable energy sources.

### Second-Largest Result in Company History

The achieved figure of 13.7 GWh marks the second-highest quarterly result in the entire history of Tesla's energy division. The absolute record was set a year earlier, but current figures clearly demonstrate that high shipment volumes are no longer an anomaly. Experts note that the industrial energy storage market is experiencing rapid development, and Tesla holds a leading position thanks to its flagship Megapack and Powerwall products.

### Evolution of the Energy Division

While in the early stages of its development the Tesla Energy division deployed relatively modest volumes of storage measured in megawatt-hours, the situation changed dramatically during 2025–2026. Today, quarterly figures are consistently measured in double-digit gigawatt-hours. The company has scaled production at specialized facilities, allowing it to meet growing demand from major corporate clients and energy utilities worldwide.

### Automotive Production Context

The scale of Tesla's energy business becomes particularly noticeable when compared with the key results of the automotive segment for the same reporting period. Specifically, in the third quarter of 2026, the car manufacturing giant produced 464,391 electric vehicles and successfully delivered 486,532 cars to customers. Although vehicle manufacturing still accounts for the bulk of revenue, the rapid rise of the energy sector diversifies the company's revenue streams and reduces overall market risks.

### Contradictory Data

Despite the company's official consolidated reporting, discussions persist within the expert community regarding the methodology used to calculate deployed capacities. Some analytical agencies point to discrepancies between factory shipments and energy storage facilities actually commissioned and put into operation. Nevertheless, Tesla representatives insist on the accuracy of their metrics, which reflect the total capacity of storage systems delivered to clients.
