The construction of SS 110/35/10 kV Kotor (Škaljari) and 110 kV OHL Tivat - Kotor is the project of the connection of one of the most important tourist centers in Montenegro to the transmission network, whereby difficulties in power supply would be significantly reduced.
Project implementation includes:
- construction of SS 110/35 kV Kotor (Škaljari) 2×20 MVA in GIS design;
- construction of OHL 110 kV Tivat - Kotor in the length of 5.84 km as a double-circuit line from SS Kotor to Trojice for the purpose of future connecting to SS 400/110/35 kV Lastva;
- installation of a new 20 MVA transformer in SSKotor.
The construction of SS 110/35 kV Kotor is completed. The Contractor is Consortium EuroZox, Eminent, Institut sigurnost.
Performance of construction works-construction of access roads, as also excavations and concrete-work of towers foundation, is in progress. The Contractor is the company Elnos.
The subproject of the installation of a new transformer 20 MVA is in the final phase of purchasing transformer. The supplier is Novi Volvox.
The expected benefits from this project are:
- reducing losses in distribution network;
- reliable power supply of consumers;
- improving voltage and reactive conditions in the area of Kotora;
- load-shedding of transformations 110/35 kV in SS Tivat.
The total project value is about 5 million €.
The project has been fully completed.
| CBA Indicators/Project | TS 110/35/10 kV Kotor (Škaljari) and DV 110 kV Tivat-Kotor |
| B1.Higher security of power supply | Enables the delivery of approximately 244,768 MWh of electricity annually, or around €183,576 per year (it is estimated that of the total consumption, without the Škaljari TS and its associated 110 kV line, kV line, 12 MW can be supplied from the direction of Cetinje in the event of an emergency, should the 35 kV Tivat–Škaljari line fail). In 2020, an increase in peak power at the Kotor substation is expected to 20 MW in winter and 17 MW in summer. The capacity of the existing 35 kV line is around 15 MW (Cu 95 mm²), which requires a reduction in consumption of approximately 5 MW in winter and 2 MW in summer. On an annual basis, this amounts to around 20 GWh, or approximately €1.5 million. |
| B2.Social and economic benefits (mil€) | It enables an unlimited increase in consumption in the transmission network and thus has a positive impact on the development of tourism. |
| BetterRES integration | Has no influence |
| Before fourVariation in losses (GWh) | Reduction of distribution network losses of approximately 4.2 GWh (with annual costs of approximately €129,360) |
| B5.Variation in CO₂ emission (%)₂ (%) | Has no influence |
| B6.Technical resilience/system security | It does not contribute to this criterion. These effects will become apparent at a later stage of the development of the transmission network in this area. |
| B7.Flexibility | Regardless of the construction schedule changes for other projects, the benefits remain the same, so the project is flexible. |
| Grid transfer capacity (GTC) | The transmission network's output capacity to the distribution network in the area of the Bay of Kotor is being increased. |
