Tesla’s energy business spans storage deployments, generation-and-storage finances, Powerwall and Megapack products, charging infrastructure, and vehicle efficiency. The figures below distinguish global company-reported measures from U.S. EPA fleet and production statistics, and separate observed results from estimates and forecasts.

Tesla Energy Storage Deployments and Growth
Tesla’s storage figures are product flows measured in GWh, not cumulative installed capacity, revenue, or customer count. The company reported 31.4 GWh globally during 2024, compared with 14.7 GWh in 2023, while Q4 2024 reached 11.0 GWh, a quarterly record at the time (Tesla Fourth Quarter 2024 Production, Deliveries & Deployments).
| Period | Global storage deployment | Definition |
|---|---|---|
| Q1 2024 | 4.053 GWh | Company-reported product deployment |
| First half 2024 | 13.46 GWh | Cumulative product deployment |
| Q4 2024 | 11.0 GWh | Company-reported quarterly deployment |
| Calendar year 2024 | 31.4 GWh | Annual product deployment |
| Calendar year 2023 | 14.7 GWh | Annual comparison series |
Q1 2024 was Tesla’s highest quarterly deployment at that point, according to the company’s operational release (Tesla First Quarter 2024 Production, Deliveries & Deployments). Tesla also reported 3.2 GWh in Q2 2024 and 4.1 GWh in Q3 2024 in its operational-summary material (Tesla Q3 2024 Update).
The same filing contains adjacent quarterly columns with 6.9 GWh and 9.4 GWh entries, but the extracted material does not safely preserve every quarter label. Those values should remain tied to the filing’s table headers rather than being reassigned here; the filing also presents a 6.9 GWh entry and describes a 75% comparison against the immediately preceding 4.0 GWh quarter (Tesla Q3 2024 Update).
Tesla Energy Revenue and Financial Trends
Tesla reports energy generation and storage as a global segment. GAAP revenue was $1.559 billion in Q3 2023, versus $1.117 billion in Q3 2022; for the first nine months, revenue was $4.597 billion in 2023 versus $2.599 billion in 2022 (Tesla Q3 2023 Form 10-Q).
The 2024 filing reports $1.454 billion of revenue in Q2 and $3.014 billion for the first six months. Tesla’s comparison says Q2 revenue increased by $573 million year over year, while first-half revenue decreased by $1.46 billion year over year (Tesla Q2 2024 Form 10-Q).
| Financial measure | Period | Amount |
|---|---|---|
| Energy generation and storage revenue | Q3 2022 | $1.117 billion |
| Energy generation and storage revenue | Q3 2023 | $1.559 billion |
| Energy generation and storage revenue | First nine months 2022 | $2.599 billion |
| Energy generation and storage revenue | First nine months 2023 | $4.597 billion |
| Energy generation and storage revenue | Q2 2024 | $1.454 billion |
| Energy generation and storage revenue | First six months 2024 | $3.014 billion |
| Cost of revenue | Q2 2024 | $2.274 billion |
| Cost of revenue | First six months 2024 | $3.506 billion |
These are segment figures, not storage-only sales. The rounded values in Tesla’s filing should not be treated as independently recalculated totals.
Tesla Energy Profit and Margin Statistics
Energy-generation-and-storage gross profit was $381 million in Q3 2023, compared with $104 million in Q3 2022. For the first nine months, the corresponding figures were $827 million in 2023 and $129 million in 2022 (Tesla Q3 2023 Form 10-Q).
In the first six months of 2024, gross profit reached $1.143 billion, including $740 million in Q2. Tesla reported a 24.6% gross margin for both Q2 and the first half of 2024, compared with 18.4% in Q2 2023 and 14.7% for the first six months of 2023 (Tesla Q2 2024 Form 10-Q).
| Measure | 2023 comparison | 2024 or later measure |
|---|---|---|
| Gross profit, quarterly | $381 million in Q3 2023 | $740 million in Q2 2024 |
| Gross profit, cumulative period | $827 million, nine months 2023 | $1.143 billion, six months 2024 |
| Gross margin, quarterly | 18.4% in Q2 2023 | 24.6% in Q2 2024 |
| Gross margin, cumulative period | 14.7%, first half 2023 | 24.6%, first half 2024 |
Tesla later said the Energy business achieved its highest-ever gross profit in Q4 2024, without giving an exact segment dollar amount in the cited passage (Tesla Q4 2024 Update). In Q3 2025, Tesla reported energy-generation-and-storage gross profit of $1.1 billion, rounded in the company’s update (Tesla Q4 2025 Update).
Powerwall and Megapack Scale
Tesla said Powerwall deployments reached another record quarter in Q4 2024. The same update states that construction of Megafactory Shanghai was completed in December 2024 and ramping began in Q1 2025; neither milestone supplies a production-volume figure (Tesla Q4 2024 Update).
The company’s 2025 global Powerwall virtual-power-plant network supported more than 89,000 events and covered more than 1 million installed units. Tesla also estimated that this activity allowed homeowners to save more than $1 billion in electricity bills; that is a company estimate, not an independently audited consumer-outcome study (Tesla Q4 2025 Update).
Megafactory Houston is planned to support up to 50 GWh per year of Megapack 3 manufacturing capacity in 2026. That figure is a forecast of planned capacity, not achieved production, while Megablock’s announced architecture integrates four Megapack 3 units (Tesla Q4 2025 Update).
Tesla Charging and Energy Infrastructure Data
Tesla’s operational summaries provide a global view of locations and Supercharger infrastructure. In Q3 2024, the company reported 1,306 company locations, 6,706 Supercharger stations, and 62,421 connectors; the prior-quarter location figure was 1,286 (Tesla Q3 2024 Update).
| Global infrastructure measure | Q3 2024 | Q2 2025 |
|---|---|---|
| Company locations | 1,306 | 1,454 |
| Supercharger stations | 6,706 | 7,377 |
| Supercharger connectors | 62,421 | 70,228 |
| Mobile-service vehicles | Not reported in cited Q3 figure | 1,684 |
By Q2 2025, Tesla reported 1,454 company locations, 7,377 Supercharger stations, 70,228 connectors, and a mobile-service fleet of 1,684 vehicles (Tesla Q2 2025 Form 10-Q). These are company-reported counts, and the location category follows Tesla’s own definition.
Tesla Energy Efficiency and Emissions Context
The EPA’s vehicle measures are not stationary-storage statistics. They describe U.S. light-duty-vehicle fleets or production, and EPA fuel economy is a vehicle energy-use measure rather than a direct measure of Tesla Energy products.
For EPA model year 2024 manufacturer comparisons, Tesla’s all-electric fleet recorded 117.1 miles per gallon equivalent. The EPA reported 27.2 mpg for average new-vehicle real-world fuel economy across U.S. new light-duty vehicles (Highlights of the Automotive Trends Report).
- Battery-electric vehicles represented 7% of all new vehicles in U.S. EPA model year 2024 production data.
- Battery-electric vehicles represented 30% of car SUVs in U.S. EPA model year 2024 production data.
- Battery-electric and plug-in-hybrid vehicles raised car-SUV fuel economy by 9.0 mpg in the U.S. EPA model year 2024 comparison.
- Without battery-electric and plug-in-hybrid vehicles, EPA estimated that average new-vehicle fuel economy would have been 1.7 mpg lower in model year 2024.
These fleet-level effects are not Tesla-only results. They describe how powertrain categories affected the broader U.S. production and efficiency measures in the EPA report (Highlights of the Automotive Trends Report).
For model year 2023, EPA reported average new-vehicle real-world CO2 emissions of 319 grams per mile. The agency estimated that EVs and PHEVs reduced average new-vehicle CO2 emissions by 38 grams per mile and improved average new-vehicle fuel economy by 2.2 mpg; these are fleet comparisons, not Tesla-specific lifecycle results (2024 EPA Automotive Trends Report: Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975).
The combined U.S. production share of battery-electric, plug-in-hybrid, and fuel-cell vehicles rose from 6.7% in model year 2022 to 11.5% in model year 2023. That measure combines three powertrain categories and should not be read as a Tesla market-share statistic (2024 EPA Automotive Trends Report: Greenhouse Gas Emissions, Fuel Economy, and Technology since 1975).
