Our Members


ELPEDISON ENERGY S.A. is α company established by three of the most significant groups of companies in Greece and Italy, i.e. HELLENIC PETROLEUM Group, one of the largest local commercial/industrial groups in the field of petroleum and petrochemical products, EDISON SpA, the Italian group which is the longest-operating power producing group in Europe, and ELLAKTOR Group, the most powerful Greek business group in construction, project management, holdings and concessions in the fields of infrastructure, real estate and energy; the company is the joint effort of the three groups in the field of power production.

Since 2005, ELPEDISON ENERGY SA (formerly ENERGY THESSALONIKI) has been the first and biggest independent power producer in Greece, with total installed capacity in commercial operation which today reaches 811 MW. The company, having implemented an important investment plan worth €525 million until today, operates and manages two (2) wholly owned cutting-edge combined cycle units using natural gas in Thessaloniki (390 MW) and Thisvi in Viotia (421 MW).


KORINTHOS POWER S.A. shareholders are PROTERGIA (65%) and MOTOR OIL (35%).

KORINTHOS POWER owns and operates a Gas-fired Combined Cycle Thermal Plant of 436 MW in Agioi Theodoroi, Korinthia. Engineering, procurement, construction and commissioning of the plant, including the GIS substation, have been carried out by METKA SA. The plant entered commercial operation in April 2012.

The company has been certified and implements: Quality Management System according to EN ISO 9001:2008, Environmental Management System according to EN ISO 14001:2004 and Health and Safety Management System according to OHSAS 18001:2007.


HERON is dynamically active in the sectors of power production and supply since 2004 through HERON THERMOELECTRIC S.A. (HERON I) and HERON THERMOELECTRIC STATION OF VIOTIA S.A. (HERON II), respectively. Since June 2009, the Groups GEK-TERNA and GAZ DE FRANCE SUEZ participate in the above companies by 50% each.

HERON II’s Thermoelectric Combined Cycle Gas Turbine (CCCT) has a capacity of 435 MW and is located right next to OCGT HERON I, 4 km south of the city of Thiva, in the region of Viotia, upon the old Thiva – Elefsina National Road, in an agricultural-industrial area with an average altitude of 295m.

The selected site neighbors with the natural gas transmission system as well as the High Voltage electric transmission system of 150 and 400KV, respectively.

The station is using state-of-the-art technology in the electricity production sector. Its efficiency rate, compared with the average performance of gas-fired power plants in operation within the Greek system, results to top-ranking classification of the selected technology. The unit’s high efficiency also results to reduced fuel consumption, and thus low gas emissions (CO2), a fact that renders HERON II as the most environmentally friendly conventional power plant, right after the Renewable Energy Sources.

The construction of the station commenced in 2007 and was successfully completed in 2010 by TERNA (EPC), when it also began its commercial operation.
