Siemens Energy to provide gas turbines for a new Greek combined cycle plant

Siemens Energy is supplying its HL-class gas turbine technology to Greece as part of a new combined cycle power plant in Komotini in the northeast of the country. The finished plant will have an installed electrical capacity of 877 MW. The construction of the new plant is of strategic importance for Greece. It will cover the country’s increased demand for electricity, which will result from the gradual withdrawal of lignite production units. The switch to a modern gas-fired power plant will reduce CO2 emissions by up to 3.7 million tons per year compared to a coal power plant. Customer Terna S.A. is building the entire plant for the project company Thermoilektriki Komotinis M.A.E. The company is owned in equal parts by Motor Oil Renewable Energy (MORE) and GEK Terna. Commissioning of the plant is scheduled for mid-2024.

The new power plant will be fired with natural gas and is designed as a multi-shaft plant, with one gas turbine and one steam turbine each driving their own generator. The Siemens Energy scope of supply includes a power island consisting of an SGT5-9000HL gas turbine, an SST5-5000 steam turbine, an SGen5-3000W generator for the gas turbine, an SGen5-1200A generator for the steam turbine, the heat-recovery steam generator, and the SPPA-T3000 control system.
