Capacity type considered for hosting capacity information	Firm
Description of the methodology that leads to firm capacity results	Check for potential violations of the “3 GW criterion” considering customers (DSOs and directly connected units) that are already connected or have a reservation. For substations with four or fewer transmission lines, the maximum transmission line capacity must be considered.
Description for the criteria and methodologies used that lead to the published information	For substations where a connection is possible, the firm capacity is displayed.
Main assumptions/disclaimers behind calculations	The published information is based on snap shots of the grid development and reserved customer connections, they should be considered as indicative. Recent developments can change the availability and suitability of locations.
