11. Το γεγονός ότι από τις διατάξεις της παρούσης δεν προκαλείται δαπάνη σε βάρος του κρατικού προϋπολογισμού. Σκέφτηκε ως εξής: Επειδή, σύμφωνα με το άρθρο 92 παρ. 4 A (ii)του Κώδικα Διαχείρισης ΕΣΦΑ (σχετικό 5): «Στο Σχέδιο Προγράμματος Ανάπτυξης αναφέρονται διακριτά Έργα τα οποία περιλαμβάνονται για 1 https://www.rae.gr/diavoulefseis/19379/ 2 https://www.rae.gr/diavoulefseis/21985/ 3 https://www.rae.gr/diavoulefseis/31913/ -2- ΑΔΑ:

πρώτη φορά στο Σχέδιο […]

1. ii)με πρωτοβουλία του Διαχειριστή, στο πλαίσιο των αρμοδιοτήτων του (Έργα Ανάπτυξης ΕΣΦΑ). Για τα έργα αυτά περιλαμβάνεται: α) Τεκμηρίωση της σκοπιμότητας ένταξης του έργου στο Πρόγραμμα Ανάπτυξης, σύμφωνα με τα κριτήρια της διάταξης της παραγράφου [2], β) Τα τεχνικά χαρακτηριστικά του έργου και ο τρόπος υλοποίησης αυτού, με αναλυτική περιγραφή των επί μέρους σταδίων υλοποίησης και, ιδίως, του σχεδιασμού, της αδειοδότησης, της κατασκευής και της θέσης σε λειτουργία αυτού, γ) Χρονοδιάγραμμα υλοποίησης του έργου με συγκεκριμένα χρονικά ορόσημα, μεταξύ των οποίων η Έναρξη Έργου, η Ημερομηνία Ολοκλήρωσης Έργου και η Ημερομηνία Έναρξης Λειτουργίας Έργου, δ) Τεκμηρίωση της συμφωνίας του χρονοδιαγράμματος υλοποίησης του έργου με το χρονοδιάγραμμα κάθε άλλου λειτουργικά σχετιζόμενου έργου περιλαμβανομένου ή μη στο Σχέδιο, ώστε να επιτυγχάνεται η έγκαιρη και εντός του προβλεπόμενου οικονομικού προϋπολογισμού επίτευξη των στόχων του Προγράμματος Ανάπτυξης, ε) Προϋπολογισμός κόστους, τρόπος χρηματοδότησης και τρόπος ανάκτησης των αντίστοιχων επενδύσεων καθώς και: (
2. i)Στην περίπτωση Έργου Ανάπτυξης ΕΣΦΑ, εκτίμηση σχετικά με την επίπτωση στη Μέση Χρέωση Χρήσης ΕΣΦΑ, έναντι του οφέλους που προκύπτει από την υλοποίηση του έργου αυτού σε σχέση με την ασφάλεια εφοδιασμού της χώρας με φυσικό αέριο και την ανάπτυξη ανταγωνισμού στην εθνική και περιφερειακή αγορά φυσικού αερίου. (
3. ii)Στην περίπτωση Έργου Σύνδεσης Χρηστών, εκτίμηση σχετικά με τη μεταβολή της Μέσης Χρέωσης Χρήσης ΕΣΦΑ κατά την Περίοδο Υπολογισμού Τιμολογίων από την υλοποίηση του έργου». Επειδή, το έργο «Αγωγός Νέας Μεσημβρία – Ειδομένη/Γευγελή και Μετρητικός/Ρυθμιστικός Σταθμός» περιλήφθηκε από το Διαχειριστή για πρώτη φορά στο Πρόγραμμα Ανάπτυξης του ΕΣΦΑ για τα έτη 2017-2026 και εγκρίθηκε με την υπ’ αριθμ. 236/2019 Απόφαση της Αρχής (σχετικό 6), στην οποία ρητά αναφέρεται: «Ένταξη στη ΡΠΒ (εξαιρουμένων των επιχορηγήσεων): υπό την προϋπόθεση διεξαγωγής δεσμευτικής διαδικασίας κατανομής δυναμικότητας «market test» σε συνεννόηση και μετά από σύμφωνη γνώμη της ΡΑΕ η οποία δεν θα οδηγήσει σε αύξηση της Μέσης Χρέωσης Χρήσης ΕΣΦΑ». Επειδή, σύμφωνα δε με το σκεπτικό της υπ΄αριθμ. 116/2021 Απόφασης της Αρχής με την οποία εγκρίθηκε το πλέον πρόσφατο Πρόγραμμα Ανάπτυξης ΕΣΦΑ και αφορά στα έτη 2021-2030 (σχετικό 7): «Το έργο αποσκοπεί στη διασύνδεση των συστημάτων φυσικού αερίου Ελλάδας και Βόρειας Μακεδονίας για την προώθηση της περιφερειακής ανάπτυξης της αγοράς φυσικού αερίου, προς όφελος της Βόρειας Μακεδονίας, καθώς θα συμβάλει στη διαφοροποίηση των πηγών προμήθειας της χώρας και θα έχει θετικό αντίκτυπο στον τελικό καταναλωτή της εν λόγω αγοράς. Για το σκοπό αυτό έχει υπογραφεί Μνημόνιο Συνεργασίας ανάμεσα στον ΔΕΣΦΑ και την ΜER τον Οκτώβριο 2016. Για τους ανωτέρω λόγους, όπως είχε σημειωθεί και στην απόφαση ΡΑΕ 755/2020 για την έγκριση του Προγράμματος Ανάπτυξης 2020‐2029, το εν λόγω έργο εντάσσεται μεν στη ΡΠΒ Μεταφοράς, ωστόσο παρίσταται εύλογο να ανακτηθεί το κόστος επένδυσης από τους Χρήστες που δραστηριοποιούνται στην αγορά της Βόρειας Μακεδονίας. Για το λόγο αυτό, κρίνεται σκόπιμη η διενέργεια Market Test, οι όροι του οποίου θα εγκριθούν από τη ΡΑΕ. Προφανώς, η επιτυχία του εν λόγω Market Test αποτελεί πρόκριμα για την τελική έγκριση της Αρχής. Το εν λόγω έργο βρίσκεται στο στάδιο του βασικού σχεδιασμού και έχουν εγκριθεί οι περιβαλλοντικοί όροι. Η ημερομηνία υλοποίησής του έχει μετατεθεί για τον Ιούνιο 2024, καθώς δεν έχει ολοκληρωθεί η συμφωνία με τη Βόρεια Μακεδονία για τη διενέργεια του Market Test. Η ως άνω χρονική μετάθεση κρίνεται αποδεκτή.» -3- ΑΔΑ:

Επειδή, σύμφωνα με την υπ΄αριθμ. 116/2021 Απόφαση της Αρχής (σχετικό 7) το έργο εντός της ελληνικής επικράτειας συνίσταται σε: • Αγωγό μήκους 54 km και διαμέτρου 30 in, με πίεση σχεδιασμού 80 barg και μέγιστη πίεση λειτουργίας 66.4 barg οποίος ξεκινά από την Νέα Μεσημβρία (Σημείο σύνδεσης κατάντη του Συμπιεστή Ν. Μεσημβρίας) έως το Μεθοριακό Σταθμό U-7550 που ανήκει στα Διοικητικά Όρια της Κοινότητας Ευζώνων, ανατολικά από τον ποταμό Αξιό. • Συνοριακό Μετρητικό Συνοριακό Σταθμό (ΜΣΣ) στην περιοχή διασύνδεσης (εκτιμώμενη δυναμικότητα 430.000 Nm3/h) • Σταθμό Ξεστροπαγίδων-αποστολής (Launcher Scraper Stations) στην διασύνδεση με τον ΕΣΜΦΑ στην Νέα Μεσημβρία • Σταθμό Ξεστροπαγίδων-αποστολής (Launcher Scraper Station) και υποδοχής (Receiver Scraper Station) στην περιοχή του ΜΣΣ. Επειδή, περαιτέρω, στην υπ΄αριθμ. 116/2021 Απόφαση της Αρχής αναφέρεται ότι: «Το έργο θα υλοποιηθεί μετά την ολοκλήρωση του market test και την υπογραφή συμφωνίας συνεργασίας με την ΝER, η οποία θα περιλαμβάνει τα στάδια που πρέπει να ακολουθηθούν και από τις δύο πλευρές για την υλοποίηση της διασύνδεσης και θα αναλύει τις λεπτομέρειες των υποχρεώσεων και ευθυνών κάθε πλευράς.». Επειδή, στο πλαίσιο αυτό ο Διαχειριστής με το σχετικό 8 υπέβαλε την πρότασή του για τα ακόλουθα δύο κείμενα που διαμορφώνουν το πλαίσιο για τη διενέργεια του Market Test: α) τις κατευθυντήριες γραμμές για την κατανομή δυναμικότητας στο ελληνικό τμήμα του Σημείου Διασύνδεσης Ευζώνων-Γευγελής (Market Test Guidelines) και β) την Πρόσκληση για την εκδήλωση συμμετοχής στην κατανομή δυναμικότητας (Market Test Notice), παράρτημα της οποίας αποτελεί η σύμβαση για τη δέσμευση δυναμικότητας (ARCA- Advance Reservation Capacity Agreement). Τα εν λόγω κείμενα τέθηκαν σε δημόσια διαβούλευση από την Αρχή (σχετικό 10). Επειδή, ο Διαχειριστής λαμβάνοντας υπόψη τα σχόλια των συμμετεχόντων στη δημόσια διαβούλευση (σχετικό 10) υπέβαλε με το σχετικό 11 έγγραφό του στην Αρχή τις απόψεις του επί αυτών καθώς και την τελική του πρόταση για το πλαίσιο διεξαγωγής του Market Test. Επειδή, η έκβαση του Market Test θα εξαρτηθεί από το αποτέλεσμα τηςου Οικονομικής Δοκιμής, όπως ορίζεται και κατ’ αναλογία με το άρθρο 22 του Κανονισμού 2017/459 (σχετικό 4). Επειδή, με την τελική του εισήγηση ο Διαχειριστής υπέβαλε και την πρότασή του για την τιμή του συντελεστή f factor (f≤1) της Οικονομικής Δοκιμής, ο οποίος αντιπροσωπεύει την αξία της επένδυσης που πρέπει να αναληφθεί από τους χρήστες που δεσμεύουν δυναμικότητα στο Market Test. Σύμφωνα με την εισήγηση του Διαχειριστή, όπως αποτυπώνεται στο άρθρο 9 των Κατευθυντηρίων γραμμών για την κατανομή δυναμικότητας, ο συντελεστής f προτείνεται όπως λάβει τιμή 0,5. Επειδή, η Αρχή ζήτησε αιτιολογικό σημείωμα από το Διαχειριστή σχετικά με το ύψος του συντελεστή f (σχετικό 12), το οποίο τέθηκε επίσης σε δημόσια διαβούλευση (σχετικό 13). -4- ΑΔΑ:

Σύμφωνα με τις εκτιμήσεις του Διαχειριστή, η τιμή f=0,5 είναι η ελάχιστη τιμή του f η οποία οδηγεί σε μη αύξηση της μέσης χρέωσης του Συστήματος, κατά τα οριζόμενα στην Αποφαση 116/2021. Επειδή, σύμφωνα με την εισήγηση του Διαχειριστή προτείνεται η διεξαγωγή του Market Test σε ένα μόνο δεσμευτικό στάδιο, και όχι σε δύο (μη δεσμευτικό και δεσμευτικό). Καθώς το έργο έχει ενταχθεί στο Πρόγραμμα Ανάπτυξης του ΕΣΦΑ ήδη από το 2019 (σχετικό 6) και έχει γίνει ευρέως γνωστό λόγω της υπογραφής Διμερούς Συμφωνίας, στις 09.07.2021, μεταξύ της Ελληνικής Δημοκρατίας και της κυβέρνησης της Δημοκρατίας της Βόρειας Μακεδονίας για την ανάπτυξη της διασύνδεσης Ελλάδας -Βόρειας Μακεδονίας από τις εταιρείες ΔΕΣΦΑ και ΝΕR4, κρίνεται σκόπιμη η διεξαγωγή του Market Test σε ένα μόνο δεσμευτικό στάδιο προκειμένου να επιταχυνθεί χρονικά. Άλλωστε σε ένα πρώτο-μη δεσμευτικό στάδιο ενός Market Test οι διαδικασίες που λαμβάνουν παραδοσιακά χώρα - εκτίμηση ενδιαφέροντος για το σχεδιασμό του έργου & προκαταρκτικός έλεγχος νομιμοποιητικών στοιχείων - δεν είναι απαραίτητες για το συγκεκριμένο έργο, καθώς όπως αναφέρθηκε ανωτέρω ο σχεδιασμός του έργου έχει ήδη ολοκληρωθεί (σχετικό 7). Επειδή, αντίστοιχα, προκειμένου να επισπευστεί η εγκριτική διαδικασία και κατά συνέπεια το χρονοδιάγραμμα διεξαγωγής του Market Test, ο Διαχειριστής υπέβαλε και η Αρχή έθεσε σε δημόσια διαβούλευση και εγκρίνει δια της παρούσας τη συνολική πρόταση του Διαχειριστή, ήτοι των Κατευθυντηρίων Γραμμών και της Πρόσκλησης συμμετοχής στο Market Test, δεδομένου ότι δεν υποβλήθηκαν σχετικά σχόλια επί αυτού του θέματος στη δημόσια διαβούλευση. Επειδή, το έργο που αφορά στο ελληνικό τμήμα του Σημείου Διασύνδεσης Ευζώνων-Γευγελής αναμένεται να λειτουργήσει θετικά τόσο για το ελληνικό σύστημα όσο και για το σύστημα της Βόρειας Μακεδονίας καθώς όπως έχει αποτυπωθεί στο πλέον πρόσφατο εγκεκριμένο Πρόγραμμα Ανάπτυξης ΕΣΦΑ 2021-2030 (σχετικό 7): - Το έργο αποσκοπεί στη διαφοροποίηση των πηγών προμήθειας φυσικού αερίου στη Βόρεια Μακεδονία η τροφοδοσία της οποίας σήμερα εξαρτάται αποκλειστικά από τον Διαβαλκανικό αγωγό. - Η πρόσβαση της Βόρειας Μακεδονίας στο ΕΣΦΑ και ειδικότερα στον τερματικό σταθμό της Ρεβυθούσας και στο φυσικό αέριο μέσω ΤΑΡ θα ενισχύσει τον ανταγωνισμό, οδηγώντας έτσι σε δυνητικά πιο χαμηλές τιμές προμήθειας φυσικού αερίου στη γείτονα χώρα. - Το έργο προωθεί την περιφερειακή ανάπτυξη της αγοράς φυσικού αερίου και την δραστηριοποίηση περισσότερων Χρηστών συμβάλλοντας στην ανάπτυξη του ελληνικού κόμβου φυσικού αερίου. Σημειώνεται ότι o ανάντη Διαχειριστής στη Βόρεια Μακεδονία (NER) έχει υπογράψει Μνημόνιο Συνεργασίας (MoU) με το Κόσοβο και περαιτέρω με το 4 https://www.desfa.gr/press-center/press-releases/symfwnia-synergasias-gia-ton-diasyndethrio-agwgo-fysikoy-aerioy-elladas- boreias-makedonias-ypegrapsan-o-desfa-kai-h-ner-jsc-skopje -5- ΑΔΑ:

Μαυροβούνιο για τη συνέχιση του αγωγού προς τις χώρες αυτές που επίσης δεν έχουν προς το παρόν πρόσβαση σε φυσικό αέριο. - Επίσης, θα συμβάλει στην αύξηση του βαθμού χρήσης των ελληνικών υποδομών με στόχο τη μείωση των τελών χρήσης του Συστήματος μακροπρόθεσμα. Επειδή, σύμφωνα με την εισήγηση του Διαχειριστή για το Πρόγραμμα Ανάπτυξης ΕΣΦΑ 20222031 (σχετικό 9) ο σχεδιασμός του αγωγού που αφορά στο ελληνικό τμήμα του Σημείου Διασύνδεσης Ευζώνων-Γευγελής θα είναι συμβατός με το υδρογόνο και θα συμβάλει στην επίτευξη του στόχου της κλιματικής ουδετερότητας που αποτελεί στρατηγική της Ευρωπαϊκής Επιτροπής. Επειδή, με βάση τα παραπάνω, καθώς και την ανάλυση που περιλαμβάνεται στο αιτιολογικό σημείωμα του Διαχειριστή για τον παράγοντα f, το έργο επαύξησης δυναμικότητας αναμένεται να αποφέρει σημαντικά οφέλη στην αγορά φυσικού αερίου και στο σύστημα μεταφοράς στην Ελλάδα και στη Βόρεια Μακεδονία καθώς και να οδηγήσει σε μείωση του μέσου τιμολογίου χρήσης ΕΣΦΑ, κρίνεται εύλογο όπως ο παράγοντας f λάβει την τιμή 0,

1. Επειδή, σύμφωνα με τη πρόταση του Διαχειριστή το ύψος της εγγύησης που θα πρέπει να προσκομιστεί για τη συμμετοχή στο Market Test ανέρχεται σε 100.000€ και αντιστοιχεί περίπου σε ποσοστό 70% της μέγιστης ετήσιας δυναμικότητας σε αντίθεση με το 20% που προβλέπεται στις περιπτώσεις προϊόντων δυναμικότητας ετήσιας διάρκειας στα Σημεία Εισόδου του ΕΣΦΑ σύμφωνα με τον Κώδικα Διαχείρισης ΕΣΦΑ (σχετικό 5), με βάση την εκτίμηση του Διαχειριστή για τα τιμολόγια χρήσης του ΕΣΦΑ. Επειδή, σύμφωνα με το εγκεκριμένο από την Αρχή Πρόγραμμα Ανάπτυξης ΕΣΦΑ για την περίοδο 2021-2030 (σχετικό 7), το εκτιμώμενο ύψος της επένδυσης που θα πρέπει να υλοποιηθεί από τον Διαχειριστή του ΕΣΦΑ ανέρχεται σε 51,4 εκ. €. και αντιστοιχεί περίπου στο 10% του συνολικού προϋπολογισμού του Διαχειριστή για την ανάπτυξη του ΕΣΦΑ. Το κόστος αφορά στο ελληνικό τμήμα του Σημείου Διασύνδεσης, το οποίο για να είναι λειτουργικό προϋποθέτει έργα και στο έδαφος της Βόρειας Μακεδονίας από τον ανάντι Διαχειριστή ΝΕR. Για να υπάρξει επαρκής διασφάλιση για την κατασκευή και λειτουργία του έργου και καθώς δεν υπήρξαν σχετικά σχόλια στη δημόσια διαβούλευση (σχετικό 10), κρίνεται εύλογο το προτεινόμενο από τον Διαχειριστή ύψος της εγγυητικής επιστολής συμμετοχής στο Market Test, ήτοι 100.000€. Επειδή, στην πρόταση του Διαχειριστή του ΕΣΦΑ προσδιορίζεται, μεταξύ άλλων, η διαδικασία που θα ακολουθηθεί σε περίπτωση θετικής έκβασης της οικονομικής αξιολόγησης των δεσμευτικών προσφορών των ενδιαφερομένων χρηστών, η οποία περιλαμβάνει τη σύναψη Σύμβασης Δέσμευσης Δυναμικότητας μεταξύ του χρήστη μεταφοράς, στον οποίο θα κατανεμηθεί δυναμικότητα και του Διαχειριστή του ΕΣΦΑ. Επειδή, σύμφωνα με το άρθρο 71 του νόμου 4001/2011, «
2. Για τη δέσμευση δυναμικότητας του ΕΣΦΑ συνάπτονται Συμβάσεις μεταξύ του ΔΕΣΦΑ ΑΕ και των Χρηστών, σύμφωνα με τις διατάξεις της περίπτωσης α` της παραγράφου 2 του άρθρου 68.» -6- ΑΔΑ:

Επειδή, σύμφωνα με την παράγραφο 2 του άρθρου 68 του νόμου 4001/2011, «Στο πλαίσιο των ανωτέρω υποχρεώσεων ο ΔΕΣΦΑ ΑΕ: (α) Παρέχει στους Χρήστες πρόσβαση στο ΕΣΦΑ με τον πλέον οικονομικό, διαφανή και άμεσο τρόπο και για όσο διάστημα επιθυμούν, χωρίς να θέτει σε κίνδυνο την ομαλή και ασφαλή λειτουργία του ΕΣΦΑ. Για το σκοπό αυτόν συνάπτει με τους Χρήστες Συμβάσεις Μεταφοράς, Συμβάσεις Χρήσης Εγκατάστασης ΥΦΑ και Συμβάσεις Χρήσης Εγκατάστασης Αποθήκευσης, σύμφωνα με πρότυπες συμβάσεις, οι οποίες καταρτίζονται και δημοσιεύονται από το ΔΕΣΦΑ ΑΕ στην ιστοσελίδα του, μετά από έγκριση της ΡΑΕ.» Επειδή, σύμφωνα με την παράγραφο 2 του άρθρου 95Δ του Κώδικα Διαχείρισης ΕΣΦΑ (σχετικό 5): «Η Σύμβαση Μελλοντικής Δυναμικότητας καταρτίζεται εγγράφως, σύμφωνα με την πρότυπη σύμβαση η οποία εκδίδεται κατά τα οριζόμενα στην περίπτωση α) της παραγράφου [2] του άρθρου [68] και το τέταρτο και πέμπτο εδάφιο της παραγράφου [1] του άρθρου [71] του Νόμου (Πρότυπη Σύμβαση Μελλοντικής Δυναμικότητας)».

The updated documents produce legal effects for the purposes of this Market Test only when they have been duly received and acknowledged by DESFA, in accordance with Article
5. Article 7 – Allocation Procedure 7.1 In case the sum of Binding Capacities requested for each Gas Years does not exceed the Maximum GNM Capacity, DESFA shall allocate the capacity to all Market Test Participants according to their Binding Offer. 7.
6. In case the sum of Binding Capacities requested for a given Gas Year exceeds the Maximum GNM Capacity, DESFA shall consider the increase of the Maximum GNMCapacity subject to the technical and financial feasibility of such increase. 12 ΑΔΑ:

If the above is not possible, DESFA shall allocate the capacity to each Market Test Participant according to their ranking, which is determined as follows:

1. a)The present value of all Binding Capacities throughout all Gas Years for which a Market Test Participant has requested Binding Capacity in the Binding Product Form is firstly calculated (Capacity PV). The calculation refers to the end of the calendar year that corresponds to the Binding Offer Deadline and is discountedat the value of WACC.
2. b)Then, Market Test Participants are ranked according to their Capacity PV as calculated according to Article 7.2.
3. a)in decreasing order (the highest value is ranked first and the lowest value is ranked last).
4. c)The ranking list of Market Test Participants will be unique regardless of the GasYear for which it will be applied. The last Allocated Participant will be the higher ranking one for whom the remainingnon-allocated capacity is lower than its Binding Capacity, for the given Gas Year, andwho has declared, in the Binding Product Form, that it accepts an Allocated Capacitylower than its Binding Capacity. In case, for a specific Gas Year, there are more thanone such Allocated Participants with the same ranking, the remaining capacity will be allocated to them pro-rata to their Binding Capacities. Article 8 – Tariffs and Fees 8.1 The tariff for the Allocated Capacity shall be governed by the principles and methodology detailed in the Tariff Regulation as in force from time to time. 8.2 Consistently with the current tariff regulatory framework, DESFA considers applying a floating reference price. For indicative purposes, the tariff for the current regulatory period for delivering 1kWh of gas at Evzoni new exit point, according to the applicable Tariff Regulation, as in force at the time of publication of these Guidelines is equal to 4.1717691 €/(kWh/h)/y without taking into account any regulatory adjustment provisioned in the applicable Tariff Regulation. For the avoidance of doubts, the reference price effectively applied will be finally determined according to the provisions of the regulatory framework in place at thetime of the transmission service and considering the actual costs incurred by the TSO. Article 9 – Economic Test 9.1 DESFA will conduct an Economic Test to determine whether the sum of the Binding Capacities after the conclusion described in Article 7, is sufficient to ensure the financial feasibility of the Section of the Project in Greece. The economic test set out in this Article shall be carried out by DESFA after the Binding Offer Deadline and shall consist of the following parameters:
5. a)the present value of the Binding Capacities, which is calculated as the discounted sum of the respective estimated tariff, as defined in Article 8.2, multiplied by the said capacities;
6. b)the present value of the estimated increase in the allowed revenue of 13 ΑΔΑ:

DESFA, which is estimated at 56.102.291 € c)the f-factor (f ≤ 1) which is a coefficient that reflects the remaining value ofthe asset, any positive externalities, as well as the amount of booked capacity for short-term bookings. The f-factor will be equal to 0.5. The outcome of the Economic Test shall be:

1. a)positive, where the value of the parameter set out in Article 9.1.a is at leastequal to the share of the parameter set out in Article 9.1.b as defined by thef-factor;
2. b)negative, where the value of the parameter set out in Article 9.1.a is lowerthan the share of the parameter set out in Article 9.1.b as defined by the f- factor. 9.2 If the Economic Test is negative, DESFA may:
3. a)Following approval of the Authority, decrease the value of coefficient f, or
4. b)Declare the Market Test “not successful” and terminate its further continuation. In this latter case, DESFA shall inform the Authority and the Market Test Participants accordingly. 9.3 In case of a positive Economic Test, DESFA:
5. a)shall notify Market Test Participants on the final outcome of the Economic Testand
6. b)in accordance with the procedure described in Article 3, shall invite Market Participants to sign an ARCA. Article 10 – ARCA and GTA 10.1 The ARCA includes the commitment, inter alia, of:
7. a)DESFA to make available the Allocated Capacity according to the Allocation Notification at the Greek Side of the IP, starting from the Commercial Operation Date, for the term set out in the ARCA and for the Tariff determined according to the Tariff Regulation as in force; and
8. b)the Allocated Participant to reserve the Allocated Capacity in accordance with the Allocation Notification,
9. c)the Allocated Participant to sign the GTA pursuant to the provisions of the applicable Greek law in force at that time and to book the Allocated Capacity reserved in the ARCA upon DESFA’s invitation. 10.2 The Allocated Participants shall sign the ARCA as per attachment IV of the Notice. 10.3 Each ARCA shall remain in full force and effect up to the signing of a GTA, subject to Article 11.5 b), covering the totality of the Allocated Capacity booked, pursuant to the provisions of the Greek Law in force at that time. 10.4 The ARCA shall be terminated ipso jure if:
10. a)no FID is taken by DESFA following a Market Test Decision that will declare the Market Test non-successful and/or 14 ΑΔΑ:

1. b)the Section of the Project in Greece is still subject to conditions in DESFA’s Ten Year Development Plan or the total cost of the Section of the Project in Greece is not approved to be included in DESFA’s Regulated Asset Base for transmission services and/or
2. c)no FID has been taken by NER, the operator responsible for the construction andoperation of the Section of the Project in North Macedonia and/or
3. d)no FID is taken by DESFA by the Cut-Off-Date specified in the ARCA. In all above cases, the ARCA Guarantee shall be returned to the Allocated Participant. 10.5 DESFA and the ARCA signatories shall bear no liability whatsoever for the period from the ARCA signing until the FID is taken by DESFA.
