Hydropower is an important renewable energy source in Switzerland and offers interesting potentials for Local Energy Communities (LEGs), especially in regions with suitable water resources.
In this article, you'll learn how hydropower can be integrated into LEGs and what opportunities it offers.
Hydropower Potential for LEGs
Small Hydropower
What is it?
- Small hydropower plants (<1 MW)
- Local production
- Suitable for LEGs
Benefits:
- Constant production (year-round)
- High availability
- Local resource
- Long-term stable
Challenges:
- Geographic requirements
- Approval procedures
- Environmental aspects
- Higher investments
Integration into LEGs
Typical Models:
- Community ownership
- Combination with solar
- Complement to other sources
Technical Aspects
Requirements
1. Water Resources:
- River or stream
- Sufficient gradient
- Constant flow rate
2. Approvals:
- Water rights
- Environmental impact assessment
- Complex procedures
Economics
Costs
Small Hydropower (10-100 kW):
- Investment: 100,000-500,000 CHF
- Dependent on location
- Higher costs than solar
ROI: Typically 15-30 years
Frequently Asked Questions (FAQ)
Is hydropower suitable for LEGs?
Yes, if:
- Suitable water resources available
- Geographic conditions suitable

- Long-term perspective
What does a small hydropower system cost?
Typically:
- 10-100 kW: 100,000-500,000 CHF
- Dependent on location
- Higher costs than solar
