Electricity Production

Electricity production mainly from thermal plants.

With regard to primary electricity production, Metlen owns gas-fired thermal plants located within the country’s south system, as well as RES plants.

The choice of a combined cycle plant is universally accepted as one of the most appropriate for the production of electricity using Natural Gas as combustion fuel, particularly for application in deregulated electricity markets. Combined cycle power plants allow aggregate net efficiency rates which, depending on design, size and fuel, exceed 57% under ISO-compliant operating conditions.

Protergia is already operating since 2008 a 334 MW High Efficiency Combined Heat and Power (CHP/High Efficiency CHP) plant in Ag. Nikolaos, Viotia, while the 444.48 MW Combined Cycle Thermal Power Plant (CCGT) in the same area, which was under the commissioning stage since January 2011, entered commercial operation in June 2011. The Combined Cycle Thermal Power Plant (CCGT) of 436.6 MW located in Korinthia which was under the commissioning stage since October 2011, entered commercial operation in April 2012.

Until the end of 2021, in the facilities of the energy center Ag. Nikolaou in Boeotia will have been added the new technology gas unit, which with the start of operation in 2022 will strengthen the system with additional power 826 MW.

The unit will be the largest, most efficient and most modern in Greece and one of the largest power stations in Europe. The 9HA.02 gas turbine of General Electric (GE), the first type "H" installed in Greece, was installed in the new unit and when put into operation will deliver 826MW to the grid, with 63% thermal efficiency, contributing to the country's energy security.
