The institution of transmission easement, introduced into the Polish Civil Code seventeen years ago, continues to raise significant interpretative doubts, despite the limited number of provisions governing it. In particular, due to the absence of an expressis verbis statutory definition of the scope of this easement in relation to power infrastructure, questions concerning the width of the easement zone remain pertinent. The article focuses on an analysis of the issues related to the delineation of the technological zone and the practical implications of this matter for transmission entrepreneurs. The conclusion presents de lege ferenda proposals, including the need for statutory clarification of the rules for determining the easement zone.
