List of scenarios, FCR bid sizes per technology and obtained values of the frequency indicators.
| N° | Scenario | System inertia∗ | Sync. generators | PEM electrolyzer | PEM fuel cell | Nadir [Hz] | RoCoF [mHz/s] |
|---|---|---|---|---|---|---|---|
| (1) | Base case (2018) | 100% | 2 × 25 MW FCR bid | Not installed | Not installed | 49.851 | 26.972 |
| (2) | Base case with H2 (2018) | 100% | No FCR support | 40 MW FCR bid | 10 MW FCR bid | 49.902 | 26.376 |
| (3) | Energy transition (2030) | 50% | 1 × 25 MW FCR bid | 20 MW FCR bid | 5 MW FCR bid | 49.876 | 53.882 |
| (4) | Low inertia with H2 (2050) | 25% | No FCR support | 40 MW FCR bid | 10 MW FCR bid | 49.902 | 99.600 |
