Compatibility of Terminology in Competition Law and Energy Law

Due to rapid technological development, the sector of energy law is very specific. In many aspects, energy law is strongly linked to the application of competition law rules. The aim of this paper is to evaluate the terminology used in the Czech Energy Act and its compliance with the terminology used in the Czech Act on the Protection of Competition, as well as its compliance with the EU terminology, namely the REMIT Regulation. Problems may be caused by inconsistencies in the terminology used, for example, when defining the relevant market and subsequently identifying a competitor/an undertaking with a significant market power or when deciding on offenses under the Czech Energy Act.
