Hydro-pumped storage of Agios Georgios and Pyrgos, Municipality of Amfilochia, Greece
TERNA ENERGY is the promoter of the project Hydro-pumped storage Agios Georgios and Pyrgos in Amfilochia, for which has concluded an agreement (Grant Agreement) with the E.U. under the “Connecting Europe Facility – Energy” for the Action “Design and Environmental Impact Assessment of the PCI 3.24 – Hydro- pumped storage in Greece- Amfilochia”.
This project is a Greek Strategic Investment by decision of the Interministerial Committee for Strategic Investments (ΦΕΚ 1787Β/6-6-2012).
TERNA ENERGY S.A assigned PLANET S.A Consulting Company:
- as it was contracted on 06.03.2015, the development of the Main Design
- as it was contracted on 01.03.2016, the development of the Detailed Design
of the project with Title “Development and Monitoring services of Supporting Technical Studies for the Hydro-pumped storage projects “Agios Georgios” and “Pyrgos” in the Municipality of Amfilochia”.
The relevant Study of Hydraulic Works was assigned to the collaboration of the consultancy firms:
- “SOFIOS CONCSULTING ENGINEERS S.A.” and
- “ MAVRONIKOLAOY & Co O.A. HYDRETME”
To the SOFIOS S.A. firm was also assigned:
- The Geotechnical Investigation (For detailed technical characteristics, click here)
- The Geological Study
- The study of Main and Auxiliary E&M Equipment
