- First delivery of HL-class gas turbine technology to Greece
- World’s most powerful combined cycle power plant in 1×1 configuration
- Reduced CO2 emissions and environmental impact, increased security of supply
Siemens Energy is supplying its state-of-the-art, highly efficient HL-class gas turbine technology to Greece for the first time. As part of a new combined cycle power plant in Komotini in the northeast of the country, it will provide reliable and economical power generation. With an installed electrical capacity of 877 megawatts (MW), it will be the world’s most powerful combined cycle power plant in 1×1 configuration. 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 with high efficiencies will reduce CO2 emissions by up to 3.7 million tons per year compared to a coal power plant. It will also reduce the environmental impact and increase the security of supply. 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.
“We trusted Siemens Energy because it’s a leading manufacturer of units with natural gas fuel, it met our requirements, and it convinced us that it will be by our side with its experience until the completion of the project. The cooperation of the two companies to interconnect Crete with the mainland is continuing in the area of electricity production,” said Ioannis Stefanatos, Director of Energy Projects at Terna S.A.
Karim Amin, Executive Vice President Generation at Siemens Energy, said: “We thank Terna for trusting Siemens Energy as its partner of choice for the prestigious combined cycle power plant in Komotini. We’re excited that our technology and expertise will play a critical role in Greece’s strategic journey of shifting from coal/lignite power plants to gas-fired power generation. Our HL gas turbines will provide a reliable supply of electricity at efficiency levels above 64 percent, resulting in a significant reduction of CO2 emissions – a target Greece is determined to achieve. We’re very much looking forward to further expanding our collaboration with Terna in Greece and other countries.“
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.
Siemens Energy is one of the world’s leading energy technology companies. The company works with its customers and partners on energy systems for the future, thus supporting the transition to a more sustainable world. With its portfolio of products, solutions and services, Siemens Energy covers almost the entire energy value chain – from power generation and transmission to storage. The portfolio includes conventional and renewable energy technology, such as gas and steam turbines, hybrid power plants operated with hydrogen, and power generators and transformers. More than 50 percent of the portfolio has already been decarbonized. A majority stake in the listed company Siemens Gamesa Renewable Energy (SGRE) makes Siemens Energy a global market leader for renewable energies. An estimated one-sixth of the electricity generated worldwide is based on technologies from Siemens Energy. Siemens Energy employs more than 90,000 people worldwide in more than 90 countries and generated revenue of around €27.5 billion in fiscal year 2020. www.siemens-energy.com.
