Investment Development With Ost Funds
Investment Development With Ost Funds
In the last three years, a total of about ALL 15,102 billion (122 million euros) have been invested in the OST network.
The focus of these investments has been mainly the increase of security and quality of electricity supply through the rehabilitation of substations mainly 110kV with depreciated equipment in time and in operation mainly manual as well as the reconstruction of 110kV and 220kV lines aiming to increase the transmission capacity of to be able to withstand not only the current peak load but also to be willing to wait for the expected renewable energy sources in the near future.
Investments are distributed throughout the country but mainly in substations and lines that have needed emergency intervention for the long time of construction of their operation and in terms of their depreciation.
More specifically during this period were performed:
1. Reconstructions of Substations:
- • Rehabilitation of the 110 kV plant in Memaliaj Station
- • Rehabilitation of the 110 kV plant in Laç1 Station
- • Reconstruction of 110 kV side in Kajan Substation
- • Reconstruction of 110 kV Jagodina Substation
- • Reconstruction of Station 110/35/20/6 Lushnje (Plasma).
- • Reconstruction of the 110 kV plant of Librazhd substation (telecommunication equipment remains to be installed)
- • Rehabilitation of the 110 kV side of Fushë-Arrëz Substation
- • Rehabilitation of the 110 kV plant in Laç 2 Station
- • Rehabilitation of the 110 kV plant of the Rubik Substation
- • Rehabilitation of the 110 kV side of Iba Substation
- • Civil works for the reconstruction of the 110 kV tract of the line Fier - Kuçovë
- • Civil works for repairs and reconstructions in Rrashbull and Zemblak substation
- • Rehabilitation of the 110 kV side of the Prrenjas substation
2. Completed investments: reconstructions and construction of new lines:
- • New 110kV line with two circuits Ulez-Skuraj.
- • Reconstruction of TL 110 kV Line Lac1 -Lac 2
- • Dismantling and construction of a new 110 kV line with a Skuraj-Laç1 circuit
- • Construction of TL Line, 110 kV, N / Station Sallmone - Lalëz Bay and additional 110 kV tract in N / Station Sallmone
- • Works for the completion of the 110 kV cable line Tirana2-Selitë and the connection with the 110/20 kV Kombinat substation.
Meanwhile, the following projects are being implemented:
- Construction of 220/110/35 kV Station has started. Amounts with OST funds in the amount of 144 million ALL, the impact of which affects the entire 110kV ring of the northeastern area of the country to which a large number of sources are connected and are under construction hydric. This substation will bring: increase of security by reducing the number of disconnections and outages at existing HPPs and customers in the area, reducing technical losses and reducing the number of disconnections and unsupplied energy.
- • The 220kV Komsi line is under construction - Amounts financed by OST funds worth 199.9 million ALL. The project envisages the construction of a 220kV line with two circuits, with an installed circuit with ACSR 490/65 mm2 conductor with a length of 48.5km and consists of 147 new metal poles. The line will connect the 220kV side of Nst Komsi to Burrel and the 220kV side of the new NSt 220/110 / 35kV Amounts. The positive impact of the construction of this line is the reduction of the load of the 110kV line of the northeast ring.
- Reconstruction of 110kV lines Laç 2-Ura e Matit and Skuraj-Ura e Matit financed by OST funds worth about 233 million ALL. The project envisages:
Dismantling of the existing 110kV Laç line 2- Mat Bridge and Skuraj – Mat Bridge, construction of the new 110kV Laç line 2- Mat bridge with two circuits with ACSR 240 / 40mm2 conductor about 5.6 km long, construction of the new line 110kV Skuraj-Ura e Matit with a circuit with ACSR conductor 240 / 40mm2 about 4.5 km long. The positive impact of the construction of this line is the increase of the transmission capacity of energy flows from the power plants of Ulza, Shkopet and other HPPs in the area towards the load center mainly in Tirana.
Construction of a line with two circuits 110 kV Fiber-Librazhd and the treaties of the respective lines in the Fiber and Librazhd Substation financed by OST funds with a value of about 464 million ALL.
The project envisages the construction of a new 110kV line with two Fiber-Librazhd circuits about 23km long, with ACSR conductor 240/40 mm2 and the construction of two line tracts at Librazhd and Fiber stations. The positive impact of the construction of this line is in increasing the transmission capacity of energy flows from the currently connected HPPs and the expected RES-E in the near future, increasing the security and quality of electricity supply, improving the voltage profile within the allowed values.
Other investments whose contract was concluded in 2020 & 2021 and in the process of implementation are:
- Construction of a new 110 kV line, with a circuit Cerrik – Kajan – Kuçovë – Jagodina and rehabilitation of the output tracts of 110 kV lines of C / Stations Cerrik and Kuçovë
- Displacement of the 220 kV double circuit airline Tirana 2 – Elbasan
Reconstruction of the 110 kV line Librazhd-Prrenjas
- Construction of 110 kV double circuit line N. Elbasan Station – N. Fiber Station
- Construction of a new 110 kV double line circuit Elbasan – Cërrik
- Primary works, supply and installation of Transformer TR 63 MVA, 220/20 kV, in Substation Tirana 1, secondary works for its adaptation to existing systems
- Construction of a new 110 kV line, with a circuit Lushnje – Fier
- Construction of a new line with two circuits 110 kV Burrel – Bulqiza and rehabilitation of 110 kV Substations, Burrel and Bulqiza
