Three CCGTs to vie for two grid spots covering 1.9 GW, Aurora study shows

Three new combined-cycle gas turbine (CCGT) power plants will be vying for two spots on the electricity grid to cover an available capacity of 1.9 GW, a latest study conducted by Aurora Energy Research and covering the period between 2022 and 2030 has shown.

The Aurora Energy Research study estimated the grid’s available capacity at 2.7 GW but subtracted 820 MW to be offered by the Mytilineos group’s already-completed CCGT in Viotia’s Agios Nikolaos area, slightly northwest of Athens.

The three candidate projects are a CCGT power plant being co-developed by GEK TERNA and Motor Oil in Komotini, northeastern Greece; a power plant being constructed by power utility PPC, gas company DEPA Commercial and the Copelouzos group’s Damco Energy in Alexandroupoli, also in the northeast; as well as PPC’s Ptolemaida V, when it converts from a lignite to natural gas-fueled facility in 2028.

Development of Thermoilektriki Komotinis, the GEK TERNA-Motor Oil CCGT in Komotini, has reached an advanced stage and is considered the most efficient power plant in Greece. Once operational, it will emit 75 percent less CO2 than a lignite plant.

Work on the Alexandroupoli CCGT began last January and is slated for completion in 2025. PPC holds a 51 percent stake, DEPA Commercial has a 29 percent share, and the Copelouzos group’s Damco Energy maintains the remaining 20 percent. This facility will be equipped to also run on hydrogen and mixed fuel.
