Objective of the Prefeasibility Connection Study is to analyse possibilities for connection of the planned hydro production capacity HPP Komarnica to the transmission network of Montenegro, taking into consideration the transmission development plans of 400, 220 and 110 kV network until 2020. Prefeasibility Study of technical solutions and connections of HPP Komarnica, is made from the aspect of evacuation of power and energy into the power system of Montenegro, taking into account security criteria and least cost of possible connections.

According to the Transmission network development plan of Montenegro, construction of the OHL 400 kV Pljevlja 2-Lastva is planned to ensure secure evacuation of electricity towards the DC cable Montenegro-Italy. As a part of the 400 kV OHL from Pljevlja to Lastva, it is planned to construct substation 400/110 kV on the location Brezna. This substation will enable the connection of the new production facilities north of Niksic. The location of SS 400/110 kV Brezna will provide to new production facilities secure evacuation of power into the EPS of Montenegro and towards the HVDC cable MNE-ITA. Therefore, SS Brezna is taken into account for the definition of connection possibilities for HPP Komarnica.

For each variant load flow analyses, voltage profile analyses (including static security analysis) and assessments of investment costs were performed. For all variants short circuit calculations have been performed, where results pointed out to a certain level of increase in the value of short circuit and their impact on existing and new equipment of lines and substations.

Type of services provided:

  • Load flow and voltage profile studies
  • (n-1) static security analysis
  • Techno-economic aspects of HPP connection, in relation to the defined variants
  • Short circuit analyses according to IEC 60909
