Transitional implementation of the previous HETS Grid Code

The HETS Grid Code according to the previous market model defined both the rules for the operation of the system and the rules for the settlement of the electricity market. According to RAE's Decision 1412/2020, transactions relating to a period before the entry into force of the Balancing Market (as of November 1st 2020), are settled in accordance with the provisions of the previous HETS Management Code issued by Decision No. 57/2012 of RAE (GG B' 103 / 31.01.2012), as amended. The Grid Code and the relevant Manuals are available only in Greek.
