Battery vs Generator for flex contracts
Both batteries and generators can serve as flex assets for flex contracts. The right choice depends on several factors:
Batteries
- ✅ Zero local emissions — suitable near Natura 2000 areas
- ✅ Fast response time (milliseconds) — ideal for balancing markets
- ✅ Silent operation — perfect for urban areas and events
- ✅ Revenue stacking across multiple markets
- ⚠️ Limited duration (typically 2-4 hours at full power)
- ⚠️ Higher upfront cost per MWh
Generators (Diesel/Gas)
- ✅ Unlimited runtime (with fuel)
- ✅ Lower capital cost per MW
- ✅ Proven technology, widely available
- ⚠️ CO₂ and NOx emissions
- ⚠️ Noise and permitting requirements
- ⚠️ Not suitable for all market participation
The hybrid solution
For long call-off periods, a battery combined with a generator is often the optimal solution. The battery handles the first hours emission-free, while the generator activates only for extended periods. This minimizes emissions while ensuring compliance.
