Albania’s electricity transmission system consists of lines with a voltage level of 110 kV, 150 kV, 220 kV and 400 kV, the respective substations at these voltage levels, and all equipment, the functions of which are included in the power transmission electrical.
The main sources of electricity generation are connected to the main consumption centers by the 220 kV network and further through the 220/110 kV transformation (the 110 kV network supplies all 110 kV distribution substations that mainly represent the load node).
The 110 kV network extends to all urban areas in Albania and supplies 110 kV voltage substations belonging to the distribution system, as well as other customers who are directly connected to this network. Some of the plants, amounting to about 435 MW in production capacity, are connected to the 110 kV network and many others that are under construction are expected to be connected soon at the level of 110 kV and 220 kV.
- uninterrupted supply of electricity to the distribution system substations (OSHEE) and electricity consumers directly connected to the transmission network,
- transmission of electricity produced from domestic sources,
- as well as for transit and necessary exchanges with the countries of the region.
In this context, it develops the Transmission System in accordance with the long-term requirements of the country’s electricity supply, with the development plans of new sources of electricity and coordinates the development of the interconnection network with neighboring countries. OST sh.a. dispatches the Albanian Electricity system through the management of energy flows in the system, taking into account the implementation of all ancillary services related to the stability of the system and exchanges with other neighboring systems.
The Electricity Transmission System of Albania includes all lines with voltage of 400 kV, 220 kV, 110 kV and connecting substations between them that serve for the transmission of electricity and interconnection.
Â
The lengths of the transmission system lines (including investments made by private investors), according to the voltage level are:
- 400 kV transmission lines 445.7 km
- 220 kV transmission lines 1,250 km
- 150 kV transmission lines 34.4 km
- 110 kV transmission lines 1,693 km
The above lines are part of the Transmission system and interconnection lines with neighboring countries such as:
- 400 kV interconnection line Zemblak (Albania) - Kardia (Greece)
- 400 kV interconnection line Tirana (Albania) - Podgorica (Montenegro)
- 400 kV interconnection line Tirana (Albania) - Prishtina (Kosovo)
- 220 kV interconnection line Fierzë (Albania) - Prizren (Kosovo)
- 220 kV interconnection line Koplik (Albania) - Podgorica (Montenegro)
- 150 kV interconnection line Bistrica (Albania) - Myrtos (Greece).
The 400 kV interconnection line Tirana (Albania) – Prishtina (Kosovo) was put into operation on December 14, 2020.
The 400 kV interconnection line Tirana (Albania) – Prishtina (Kosovo) was put into operation on December 14, 2020.
The technical capacity of the exchange with neighboring countries is sufficient to carry out the necessary exchanges and transits required at any time however in certain periods, there is congestion of transmission capacities in the interconnection.
Listed below are the main Transmission System Substations.
