In the winter regimes of peak load, distribution area of Nikšić lacks the sufficient amount of reserves in the transformation to supply power to the narrower urban area, which is the reason for constructing a new substation. Besides, the construction of SS Kličevo and its connection to transmission network will create necessary preconditions for connecting future wind power plants in Krnovo to the electric power system of Montenegro.
The project of the construction of new substation includes the construction of SS 110/10 kV Kličevo in GIS design on the location of the existing SS 35/10 kV Kličevo and connection to 110 kV network by constructing a cable line to the existing SS 110/35 kV Nikšić and connecting to the existing OHL 110(35) kV Nikšić (Kličevo) - Brezna.
The expected benefits from this project are:
- improving the quality of electricity deliveries;
- providing conditions for connecting WPP Krnovo to transmission network;
- reducing losses in transmission and distribution network;
- increasing capacity in the transformation;
- safer and reliable power supply of Nikšić area.
The total estimated value of the project is about 8 million €.
The project is under construction phase and the Contractors are Consortium Novi Volvox, Eminent, Ing Invest, Institut Sigurnost and EuroZox for SS Kličevo and Consortium Bemax, Energomontaža and Institut Sigurnost for 110 kV cable SS Kličevo - SS Nikšić.
| CBA Indicators/Project | TS 110/35 kV Kličevo |
| B1.Higher security of power supply | By adding two new 110/10 kV transformers, the reliability of power supply in the Nikšić municipality is improved. This relieves the 35 kV network and the 35/10 kV transformation at the TS in the Nikšić area, which is particularly overloaded during the winter period. Furthermore, the supply conditions for consumers along the route from TS 35/10 kV Brezna to TS 35/10 kV in the Piva region are improved, thanks to the relief of the 35 kV cables from the direction of TS 110/35 kV Nikšić. |
| B2.Social and economic benefits (mil€) | It does not have a significant impact on this category. |
| BetterRES integration | There is no direct connection of RES, but it allows the integration of energy from the future Krnovo HPP (Phase I) |
| Before fourVariation in losses (GWh) | Annual losses are reduced by approximately 2,212 MWh, with a value of around €68,130. |
| B5.Variation in CO₂ emission (%)₂ (%) | Due to its importance for the operation of the future Krnovo HPP (Phase I), it will have an impact on reducing CO₂ emissions. |
| B6.Technical resilience/system security | There is no impact. These effects will become evident in a later phase of the transmission network construction in northern Montenegro. |
| B7.Flexibility | The project fits into various network development scenarios and retains its benefits. |
| Grid transfer capacity (GTC) | The outgoing capacity of the transmission network to the distribution network in the Nikšić Municipality is being increased. |
