    •  

      1.  Pending the approval by RAEWW of the Methodology for determining revenue required by the HETS Operator for operation of the Markets in accordance with the provisions of ‎Article 6.1, paragraph 1 of this Rulebook, as well as the accounting separation rules to which the HETS Operator is subject, in accordance with the provisions of Article 141 of Law 4001/2011, the approval of the Balancing Market Fee is based on the HETS Operator’s own estimates of Revenue Required for the operation of the Markets with the possibility of corrective settlement after adoption of the aforementioned decisions of the RAEWW.
      1.  By way of derogation from paragraph 5 of ‎Article 19.7, and for as long the Temporary Refund Mechanism of a portion of Revenue of Day Ahead Market remains effective, the Imbalance amount in € in each Imbalance Settlement Period t for the pre-registered entities subject to Commissioning Operation, as well as for the entities which are under Pre-Qualification Tests in accordance with Chapter 3 of this Rulebook, is calculated as the product of the Imbalance 𝐹𝐼𝑀𝐵𝑒,𝑡 in MWh, with the minimum of the relevant applicable Regulated Producer Revenue Price and the Day-Ahead Market Clearing Price in €/MWh for the respective Market Time Unit.
      2.  By way of derogation from paragraph 2 of ‎Article 19.7, with the implementation of Cross-Border Intraday Continuous Trading and for as long the Temporary Refund Mechanism for a portion of Revenue of Day Ahead Market remains effective, the Imbalance amount in € in each Imbalance Settlement Period t, is calculated for the RES Units under Commissioning Operation in the context of their connection to the Transmission System or the Distribution System, as the product of the Imbalance 𝐹𝐼𝑀𝐵𝑒,𝑡 in MWh, with the minimum value being between the corresponding Regulated Producer Revenue and the clearing price of the Day-Ahead Market in €/MWh for the respective Market Time Unit.

The aforementioned Market Schedule corresponding to DAPEEP, MSp,tΚρήτη, is transmitted by the Energy Exchange separately from the corresponding Market Schedule of the DAPEEP for the RES units it represents in the HETS.

      11. The TSO Operator may execute the Dispatch Plan for the SIS of Crete at any time, for all or for certain Market Time Units, within calendar day D-1 and/or calendar day D (“on-demand Dispatch Schedule”), in the event of an event that significantly affects the planned injection/absorption schedule of the virtual Balance Responsible Entity “Crete”. The HETS Operator shall publish the information provided for in paragraphs 6, 7 and 8 of this Article on its website and shall forward it to the Energy Exchange and the Operator of Renewable Energy Sources & Guarantees of Origin (DAPEEP) as soon as possible.
      12. Details regarding the preparation of the Dispatch Schedule of the SIS of Crete are provided in the Technical Decision “Dispatch Schedule of the SIS of Crete”.

      1. For each Balancing Settlement Period t, the energy absorption from the HETS measured by the meter of the Peloponnese-Crete interconnection shall be allocated to the Load Representatives operating in Crete based on the representation percentages calculated and sent out by the Hellenic Electricity Distribution Network Operator (HEDNO) in accordance with paragraph 9 of this Article. The quantity corresponding to each Load Representative for energy absorption from the virtual Balance Responsible Entity 'Crete', MQp,tΚρήτη, shall be assigned to a a separate portfolio from the energy absorbed by the other Offtake Facilities in the HETS represented by the same Load Representative.

      2. For each Imbalance Settlement Period t, the energy injection into the HETS measured by the meter of the Peloponnese-Crete interconnection shall be assigned to DAPEEP. The above energy injection assigned to DAPEEP, MQp,tΚρήτη, is part of a separate portfolio from the injection of the RES Units without Market Participation Obligation represented by DAPEEP in the HETS.

      3. For each Imbalance Settlement Period t, the Imbalance is calculated for each Load Representative operating in Crete, p, and for the virtual Balance Responsible Entity 'Crete',  as the difference between the energy absorption, MQp,tΚρήτη, as determined in accordance with paragraph 1 of this Article, and the relevant Market Schedule, MSp,tΚρήτη, as follows:

        IMBp,tΚρήτη = MSp,tΚρήτη - MQp,tΚρήτη
      4. For each Imbalance Settlement Period t, the Imbalance of DAPEEP, p, for the virtual Balance Responsible Entity “Crete” is calculated as the difference between the energy injection, MQp,tΚρήτη, resulting from the measurement data obtained from the meter of the Peloponnese-Crete interconnection, and the relevant Market Schedule, MSp,tΚρήτη, as follows:

        IMBp,tΚρήτη = MQp,tΚρήτη - MSp,tΚρήτη
      5. The HETS Operator shall calculate the Imbalance amount, in €, for each Discharge Settlement Period for the Load Representatives operating in Crete and for DAPEEP in accordance with the provisions of Article 89 of this Rulebook.

      6. The calculation of the amounts corresponding to the Balance Responsible Parties for the Uplift Accounts in accordance with CHAPTER 20 of this Rulebook shall be made for the total offtake, i.e. the sum of the absorption corresponding to HETS Offtake Facilities and the absorption corresponding to the virtual Balance Responsible Entity 'Crete'.

      7. The quantities corresponding to the virtual Balance Responsible Entity 'Crete' and calculated in accordance with paragraphs 1 and 2 of this Article and the corresponding Market Schedules shall not be taken into account for the purpose of calculating Non-Compliance Charges in accordance with CHAPTER 22 of this Rulebook.

      8. When performing the Initial and Corrective Settlements provided for in Article 23.1 of this Rulebook, the monthly ex-ante estimated representation rates per Load Representative sent by HEDNO in accordance with paragraph 9 of this Article shall be taken into account. During the execution of the Final Settlements or additional Corrective Settlements executed following a respective decision of the RAEWW pursuant to Article 23.1, paragraph 8 of this Rulebook, revised representation percentages per Load Representative operating in Crete shall be taken into account, and shall be sent by HEDNO in accordance with paragraph 9 of this Article.

      9. Two days before the first day of each month M, at 12:00 EET, HEDNO shall send the monthly ex-ante estimated representation rates of the Offtake Facilities in Crete for each Load Representative operating in Crete for month M. The revised representation rates per Load Representative of Crete shall be sent by HEDNO in accordance with the schedule set out in Article 23.1 of this Rulebook.

      10. The Settlement results provided for in CHAPTER 23 shall be communicated to the Balance Responsible Parties separately for the virtual Balance Responsible Entity 'Crete'.

      11. Otherwise, the settlement procedure for the energy injected or absorbed through the Peloponnese-Crete interconnection from the day of completion of Phase A of the interconnection until the day of completion of Phase B of the interconnection of Crete with the HETS shall be carried out in accordance with the provisions of Article 108C of Law 4001/2011, as in force and in CHAPTER 23 of this Rulebook.
