Hosting capacity assessment
| Capacity type considered for hosting capacity information | Firm |
| Description of what firm capacity means and the aspects that structure the definition | Firm capacity is determined based on load-flow and short-circuit analyses, substation bay availability or expansion feasibility, and local power quality. It represents the capacity granted without network limitations at the connection point and is defined in the grid connection agreement |
| Description of the methodology that leads to firm capacity results | Firm capacity: Connection granted with full capacity, without curtailment |
| Description of what flexible capacity means and the aspects that structure the definition | The connection is granted subject to potential curtailment to ensure grid security. The allowable capacity is determined on a case-by-case basis through load flow analysis and is defined in the grid connection agreement. This arrangement is typically time-dependent and remains in place until specific grid measures, where feasible, are completed, most commonly the implementation or reinforcement of grid infrastructure |
| Description of the methodology that leads to flexible capacity results | Flexible capacity: Connection granted with the possibility of curtailment to maintain grid security |
| Description for the criteria and methodologies used that lead to the published information | The firm capacity methodology is determined based on the following criteria: Results of static load-flow analyses, Short-circuit analyses, Availability of a bay in the substation or the possibility of extending the existing substation and Quality of electricity at the given location. The feasibility of connecting synchronous or asynchronous generation depends on the local quality of electricity. Likewise, the possibility of connecting either load or generation is assessed using static load-flow and short-circuit analyses. |
| Main assumptions/disclaimers behind calculations | Legal validity of information: The published information is legally non-binding. To reserve or acquire connection capacity, a formal connection request must be submitted. Minimum connection limit: The minimum size for connection to the transmission grid is 250 MW (400 kV grid). High-capacity connections: Available capacities above 1000 MW cannot be estimated without a location-specific analysis conducted within the formal connection request process. Grid evolution: Assessed in line with the infrastructure portfolio known at the time of computation. Grid users’ evolution: Based on reservations and allocations known at the time of computation. Market conditions: Reflecting the latest adequacy and flexibility study available at the time of computation. Interdependence of hosting capacities: The published capacities are valid for one location at a time only. |
