E-mobility and Local Energy Communities (LEGs) are a perfect combination: electric cars can serve as flexible storage and optimally use local renewable energy.
In this article, you'll learn how e-mobility is integrated into LEGs and what benefits this offers.
Why E-Mobility in LEGs?
Synergies
1. Renewable Energy:
- Electric cars charge with local solar power
- Optimal use of renewable energy
- CO2-free driving
2. Flexible Storage:
- Electric cars as mobile storage
- Bidirectional charging possible
- Grid stabilization
3. Community Infrastructure:
- Share costs
- Optimal use
- Scalable
Community Charging Infrastructure
Models
1. Community Ownership:
- LEG owns charging infrastructure
- All members use
- Costs are shared
2. Private with Access:
- Individual members own
- Others can use
- Access rights agreed
3. Hybrid Model:
- Mix of both models
- Flexible structure
- Optimal use
Smart Charging
Smart Charging
What is it?
- Optimized charging times
- Use of renewable energy
- Load control
- Cost optimization
Benefits:

- Cheaper prices
- Higher efficiency
Integration with Smart Grid
How It Works:
- Smart Grid controls charging
- Optimization based on production
- Automatic load shifting
- Forecast-based
Vehicle-to-Grid (V2G)
Bidirectional Charging
What is it?
- Electric car can return energy
- Mobile storage
- Grid stabilization
- Additional revenue
Economics
Costs
Charging Infrastructure:
- Wall charging station: 1,000-2,000 CHF
- Column: 5,000-15,000 CHF
