Therefore, EMCA Volt Sp. z o.o overcame a range of doubts and concerns of other entities owning infrastructures which the Line collides with. Among others, expert’s opinions were issued concerning the impact of the Line on cable lines 110 kV, MV and LV, expert’s opinions on the impact on railway lines, evaluation of the impact on the flood embankments under construction.

EMCA Volt Sp. z o.o, apart from the above mentioned expert’s opinions and assessments of the impact of the Line on other facilities, performed the following:
