Bosnia: Long-Term Transmission Network Development Plan for Period 2014 – 2023

4. September 2015. / SEE Energy News

In November 2014, the State Electricity Regulatory Commission approved the Long-Term Transmission Network Development Plan for the period 2014 – 2023, i.e., the first document of this kind.

This planning document, which was prepared by the Transmission Company and subsequently revised by the Independent System Operator in Bosnia and Herzegovina, defines the required reinforcement of the existing transmission network facilities and construction of the new ones to ensure timely commencement of activities with regard to designing, constructing and putting into operation of infrastructure necessary for a continuous supply and stable operation of the system. The total value of investments as foreseen by the Long-Term Plan amounts to €402.81 million.

The Long-Term Plan envisages the construction of 29 substations 110/x kV, 50 transmission lines 110 kV, two transmission lines 220 kV, three transmission lines 400 kV and 37 transmission line bays within the existing substations. The Plan also includes the expansion and installation of the second transformer in 34 substations 110/x, installation of one transformer 400/220/110 kV and reconstruction and rehabilitation of 112 high- and medium voltage facilities. Furthermore, it envisages the reconstruction and rehabilitation of 76 transmission lines 110 kV, 20 transmission lines 220 kV and one transmission line 400 kV as well as replacement of 52 transformers 110/x kV, one transformer 220/x kV and two transformers 400/x kV. Construction of four interconnectors is planned at the 400 kV voltage level.

Approval of the Long-Term Plan ensures qualitative preparations of annual investment plans of Elektroprenos BIH while creating conditions to more adequately meet obligations towards the European Network of Transmission System Operators for Electricity (ENTSO-E) concerning contributions to the development of the European Ten Year Network Development Plan.

Pursuant to applicable laws, a long-term transmission network development plan is developed on an annual basis and covers the forthcoming ten-year period.

Investment Plans of the Transmission Company

In 2014, the Transmission Company prepared two annual investment plans and one investment plan covering a three-year period.

The Investment Plan for the period 2014 – 2016 and the Investment Plan for 2014 were adopted at the session of the Company’s Steering Board held on 26 March 2014 and approved at the meeting of the Assembly of Shareholders held on 31 March 2014. The Plans were developed in line with planning principles

and frameworks as adopted by the Assembly and established criteria and relations in the investment structure. The documents were prepared in the function of realising the power balance on an annual basis, applying the basic standard security criterion.

The three-year Plan envisages the construction of 15 new substations 110/x kV; expansion of the existing 16 substations 110/x kV and construction of 11 new transmission lines with nominal voltage of 110 kV; reconstruction of the existing 27 substations 110/x kV as well as 14 transmission lines, including the reconstruction of one 400 kV and five 220 kV transmission lines; the replacement of one transformer 400/110 kV, one transformer 220/110 kV and 24 transformers 110/x kV.

The Investment Plan for 2014, inter alia, envisages the construction of 13 new substations 110/x kV; expansion of the existing nine substations 110/x kV; construction of five new transmission lines with nominal voltage of 110 kV; reconstruction of the existing 19 substations 110/x kV as well as five transmission lines, including one 400 kV and two 220 kV transmission lines; the replacement of one transformer 220/110 kV and 13 transformers 110/x kV.

After an analysis of the submitted documents, the State Electricity Regulatory Commission approved the Investment Plan for the period 2014 – 2016 and the Investment Plan for 2014 in April 2014.

The Transmission Company adopted the Investment Plan for 2015 at the session of the Company’s Steering Board held on 11 December 2014. Furthermore, at the meeting held on 22 De-cember 2014, the Assembly of Stakeholders approved a Decision on investments in Transmission Company’s facilities exceeding amounts of €1 million which was adopted on 11 December 2014.

In addition to including technical and economic planning criteria, the Investment Plan for 2015 also included decisions and conclusions of the Company’s Board of Directors, Steering Board and Assembly of Stakeholders of the Company defining in that way criteria and relationships in the very investment structure. This Plan was also prepared in the function of realising the power balance on an annual basis, applying the basic standard security criterion while for its drafting the Investment Plan for the period 2014 – 2016 and the Long-Term Transmission Network Development Plan for the period 2014 – 2023 were used.

The Plan includes activities on solving rigid points in the system, rehabilitation of transmission network facilities that are not operational and putting them into operation, completing 110 kV transmission line bays and replacement of network transformers in accordance with defined criteria.

After analyses made at the end of December 2014, the State Electricity Regulatory Commission approved the Investment Plan for 2015. , transmits Serbia-energy.eu
