Tesla Shanghai Factory Integrated Solution for Light Storage and Charging
——Achieve zero-carbon production with "giant power banks," saving tens of millions in electricity costs annually.
Previous situation:
Tesla's Shanghai factory has a huge electricity demand, and electricity costs are expensive during peak hours, with annual energy costs exceeding 100 million yuan.
As a global benchmark factory, Tesla needs to fulfill its commitment to "zero carbon production by 2030," but traditional power grids rely on fossil fuels.
Solution:
"Integrated Super System of Light Storage and Charging."
Photovoltaic power generation: 200,000 square meters of solar panels installed on the roof (≈30 football fields).
Energy Storage System: Equipped with a 50MWh Tesla Megapack lithium battery, storing electricity for use at night/cloudy days.
Smart Scheduling: AI predicts peak and valley electricity prices, automatically selecting the optimal charging and discharging times.
Technical Highlights:
💡
“Megapack”, absorbs solar energy during the day and transforms into a “power bank” at night.
💡
Can be fully charged within 1 hour, responds to grid frequency modulation demands within 2 milliseconds, 100 times faster than traditional solutions.
Results:
Indicator | Before the implementation of the energy storage solution | After the implementation of the energy storage solution |
Annual electricity cost | 120 million yuan | 90 million yuan (reduced by 25%) |
Green electricity coverage rate | 30% (outsourced) | 80% (self-sufficient) |
Carbon emissions | 60,000 tons/year | 20,000 tons/year (reduced by 66%) |
Emergency Power Supply Capacity | Depend on diesel generators | Can support 4 hours of production for the entire factory |
💡
"Tesla uses the 'solar energy + power bank' combination, saving money while earning a reputation for environmental protection."
