Hosting capacity assessment

Capacity type considered for hosting capacity information Firm
Description of the methodology that leads to firm capacity results Firm capacity garantees an availability of the capacity of more than 95% of the time with a complete grid respecting the N-1 criterion.
Description of the methodology that leads to flexible capacity results TBD
Description for the criteria and methodologies used that lead to the published information Capacity calculation based on the actual and planned grid. The capacity is calculated based on planned flows and respecting the N-1 criterion on a complete grid (no outages) over a complete year. No topological changes are considered, and no phase shifting transformer (PST) optimisation is performed.
Main assumptions/disclaimers behind calculations All grid connection requests greater than 250 MW for 220 kV, 400 MW for 380 kV, or capacities greater than 80% of the available power require a detailed analysis of available capacity. In addition, all grid connection requests near the border must be assessed in detail. The map only provides raw estimations, but offers no guarantees.

Options available for the investors if the map shows 'no capacity available' in their interested area The investor can contact the TSO, which will define the required reinforcement and provide estimates for the associated costs and implementation time.
