Hosting capacity assessment
| Capacity type considered for available hosting capacity information (e.g., Firm and/or Flexible) |
Firm |
| Description of what firm capacity means |
Fully available network capacity (8,760 hours/year) |
| Description of the aspects/methodology that leads to firm capacity results |
The methodology for assessing connection feasibility is based on the Distribution System Operation Rules (PPDS), Annex No. 4. The basic technical parameters for assessing connection feasibility include:
Impact on power quality parameters – primarily voltage change (ΔU) for normal and backup supply conditions caused by the generating unit being connected, including all connected and approved generating units on the same feeder. |
| Description of what flexible capacity means (if applicable) |
Flexible (non-guaranteed) capacity refers to a customer connection with a mutually agreed-upon contractual option for curtailment by the DSO, where connection to the distribution system is not guaranteed 100% of the time. This is to ensure the reliability of the distribution system. |
| Description of the aspects/methodology leading to flexible capacity results |
The calculation methodology is based on the maximum possible use of the equipment’s transmission capability throughout the year and limits power output to 5% of the annual generated energy. |
| Description for the criteria and methodologies used that lead to the published information |
Normal operating state (configuration) of the distribution system and the usability of the 110 kV/MV transformation transmission capacity. |
