Projects critical to its stability are advancing with hurdles causing major delays electrical system and smooth penetration of the growing RES production. Cases of the Argiroupoli substation, which has been completed since 2004, but until today due to successive legal difficulties, only the 150 kV side and the Western Corridor, which stalled shortly before the last two of the 310 high voltage pylons were installed, are acting on appeals five monks, are the most characteristic, but not the only ones in the list of works included ADMI in the ten-year development plan for 2024-2033. In the updated program presented yesterday to ADMIE for public consultation, four projects (including Argyroupoli KYT) are being postponed for reasons that are stated to be “beyond the administrator’s sphere of influence” (e.g. judiciary involvement, archeology, etc.). In addition, 20 projects are being rescheduled, most of which are due to a reassessment of system needs, and some due to the failure of the original plan. Licensing is a major issue affecting the implementation schedules of ADMIE projects and has been pointed out to the competent authorities by the administrator’s administration as an issue requiring intervention.

With regard to the city council of Argyroupoli, following the rejection by the local authorities of the new Environmental Impact Study (EIA) For the implementation of the 400 kV New Technology Side (GIS), ADMIE is considering burying it and is expected to re-submit the EIA for approval of the operating license. The Argyroupoli substation was designed to meet the electricity needs of East Attica and the delay in its upgrade is placing a disproportionate burden on the Pallini and Koumondur substations, leaving the system as a whole vulnerable.

A 400 kV Peloponnese-Attica connection has been included in ADMIE’s plans since 2006, but due to backlash, construction began in 2018 and was held hostage by the courts shortly before completion due to appeals. five monks. ADMI was looking for an alternative route that would not interfere with Ag Monastery. Theodoron Kalavriton and the project is moving forward. Its completion, according to ADMIE, is estimated during the second half of 2023.

The implementation of another twenty island connections is being postponed as scheduled.

Among the delayed projects is still the Ptolemaida Expansion Transmission Lines Project requested by PPC due to the delay in the expropriation declaration request due to serious cadastral inconsistencies. Due to the participation in the construction of the E65 highway, the project to change the 400 and 150 kV transmission lines is delayed, while the delay in the modernization of the 150 kV circuits in Aktio is due, according to ADMIE, to “the inability of the contractor to adapt to the new data.”

a priority

Strengthening international connections remains a top strategic priority in ADMIE’s updated development agenda, which for the first time includes specific technical parameters for new cross-border connections with Italy and Albania. It also provides for new projects worth 147 million euros to strengthen the transport system in Western and Northern Greece, where in total ADMIE is implementing projects with a budget of 550 million euros.

The connection of the islands is proceeding according to the schedule. ADMIE, however, believes that it is necessary to leave some PPC oil units on standby in case of an emergency, even after interconnections are completed. Especially for the Cyclades, he estimates that two units of 50 megawatts each should remain on standby, suggesting that Thira and Paros are also better suited to serve the other islands. In the system of Crete, after the connection with Attica is completed, it is proposed to leave in reserve from 200 to 400 megawatts of conventional units to cover the need in the event of a complete loss of electricity through the cables.
