Contract for the construction of a 400kV electricity transmission line for the electrical interconnection Greece-Bulgaria

Athens, Greece – 7July 2022 - MYTILINEOS S.A. (RIC: MYTr.AT, Bloomberg: MYTIL.GA, ADR: MYTHY US) through its Sustainable Engineering Solutions (SES) Business Unit, signed a contract with the Independent Power Transmission Operator (IPTO SA) for the complete construction of the new interconnecting overhead Transmission Line ‘T.L. 400kV High Voltage Center Ν. SANTAS - MARITSA (BULGARIA)’, of a single heavy-duty circuit (three-way conductor per phase), and the supply of all the materials required (steel, conductors, insulators, fittings) for the technical construction of said overhead transmission line. 

This segment is part of the new Greece-Bulgaria electrical interconnection, constituting an important project of pan-European interest and is expected to join the European System in the beginning of 2023.

MYTILINEOS will undertake the construction of a segment of the new interconnecting line (N. Santa – Maritsa) located on Greek territory with a total length of 30 km. The Project involves the construction of eighty-five (85) new towers of series '7' (seven).In particular, the construction of access routes for the project's needs, the complete construction of eighty-five (85) new towers, the complete installation of ACSR Cardinal conductor, steelShield Wire  conductor(SW) and OPGW conductor will be carried out, along the entire length of the line with all the relevant fittings. The dielectric cable will also be installed within the High Voltage Center NEA SANTA, terminating to the existing ODF and measurements of optic fibers and tower foundation ground resistance will be performed.

This Project will strengthen the European transmission system in the region and, for our country, it will have a positive impact on cross-border trade in electricity, while allowing safe penetration of new RES projects in Thrace and Eastern Macedonia.

Kostas Horinos, Director Power, LNG/GAS, Industrial, T&D of MYTILINEOS’ SES Business Unit, stated after the signing of the contract: "We are undertaking a complex and demanding task, capitalizing on the great experience and know-how of the upgraded Sustainable Engineering Solutions Business Unit of MYTILINEOS. We are proud of cooperating anew with IPTO SA, having already demonstrated that we can deliver projects successfully and consistently.

MYTILINEOS, keeping abreast with international trends for efficient energy distribution and transmission, is demonstrating a successful portfolio of similar projects. Its expertise in the design and construction of high-voltage lines and in particular of equivalent 400kV single-heavy-duty circuit transmission lines (such as the transmission line 400kV High Voltage Center DISTOMO-High Voltage Center AGIOS NIKOLAOS I & II constitutes the main success factor for the implementation of interconnection projects of safe distribution for increased power flows. This contributes to a rapid growth of electricity markets in Europe and Turkey.

The contract is scheduled to be completed within 9 months, in addition to the 18 months of the warranty period, and the contract value for MYTILINEOS stands at 9.974.796,04 €.
