    Construction of double-track 400 kV Ostrołęka – Olsztyn Mątki line with temporary operation of a single track with the voltage of 220kV in Ostrołęka – Olsztyn relation

    EMCA Volt sp. z o.o. in cooperation with Aldesa Nowa Energia Sp. z o.o. implemented, for Polskie Sieci Elektroenergetyczne S.A. Investor, the construction project for a power line of 400kV in Ostrołęka – Olsztyn Mątki relation. This project is critical to the ensuring of power safety in the region of Warmia, Mazury and northern Mazowsze and to improving electricity transfer from the north to the south of Poland. This project will be implemented in the following two voivodeships: warmińsko-mazurskie and mazowieckie. The line will cross the following communes: Rzekuń, Lelis, Kadzidło, Baranowo, Czarnia, Wielbark, Szczytno, Dźwierzuty, Purda, Barczewo, Dywity, Jonkowo. 138 km of a new line will replace the existing 220 kV line or partially change its route so that disturbing the local community and natural environment is reduced as much as possible. The construction of a new line will improve the reliability of the transmission network and will facilitate the counteracting of the effects of serious system failures which may results from various fortuitous events. The improvement of conditions and guarantee of power supply in communes is an opportunity for winning new investors and in consequence opening many job vacancies. Construction works conducted as part of this project began in June 2015. Currently, there ware works held in all the communes where a double track power line 400 kV Ostrołęka – Olsztyn Mątki will be built.

    EMCA Volt Sp. z o.o. has performed the following tasks as part of this project:

    • obtaining a construction permit decision for the construction of the entire Line
    • obtaining a decision on the environmental conditions
    • obtaining a construction permit decision or applying for such a decision for all facilities crossing with the Line
    • establishing transmission easement or obtaining other permanent legal titles to the lands for construction and further functioning of the Line within its entire route
    • performing construction designs and detailed designs for the construction of the Line and rebuilding colliding facilities
    • entering the Line within its entire length to the Local plans of spatial development in the communes lying within the Line route.

    There were preparatory works carried out before the construction of the Line and all the pylons for the Line were erected, wires were stretched within greater part of the Line. Currently, other colliding facilities are rebuilt and wires are stretched along the rest of the Line.
