Transmission System is the system consisting mainly of high voltage power lines and used for the transmission of electricity from a plant to a substation or another plant or between substations.

The Cyprus Energy Regulatory Authority (CERA) approves and revises the process and charging policy of the Transmission System as well as network usage fees. Also, CERA's responsibility is to approve, issue instructions and request a review whenever it deems necessary to the Transmission Rules.

The Cyprus Transmission System Operator (CTSO) is the Management Unit of the Transmission System, that was established pursuant to Article 58 and is responsible for the Transmission System as provided in Articles 62 and 63 of the Electricity Market Regulation Act.

The Transmission System Owner (TSO) is the EAC as the owner of the transmission system.
