In 2016, electricity consumption in Turkey increased by 4.44% while at the same time, its electricity generation increased just 4.2%. The country needed to quickly find a way to increase power capacity, reliability and efficiency, while also decreasing emissions.
"GE has a strong local presence and offers us a one-stop-shop service provider for all of our modernization needs. With these upgrades, our plants will be better-positioned to meet the future energy needs of Turkey's residents and businesses."Serhat ÇEÇEN, Chairman, IC İÇTAŞ Enerji Investment Holding and Yeniköy Kemerköy Elektrik Üretim ve Ticaret A.Ş.
Yeniköy and Kemerköy lignite-fired coal power plants are located in the middle of Gökova Bay, Turkey. Yeniköy has 2 units with a total of 420 MW output, while Kemerköy has 3 units with a total of 630 MW output. The plants serve around 521,000 homes and meet approximately 5% of Turkey’s energy demands.
As part of its Powering Efficiency Center of Excellence (COE) capabilities, GE’s Power Services business has agreed to provide its Fleet360* total plant solutions to modernize both plants. The modernization and full plant refurbishment will include replacing five Zamech high-pressure, intermediate-pressure, and low-pressure steam turbines and five Dolmel generators with air-cooled generators. GE will also upgrade five Rafako boilers, modernize five flue-gas desulfurization and electrostatic precipitator systems as well as the electrical and mechanical balance of plant, and will install a distributed control system.
The upgrade of the two facilities will help increase the plants’ capacity by 197.5 MW—enough to additionally power the equivalent of approximately 198,000 homes—while also significantly decreasing plant emissions. The plants’ efficiency will improve by 6 percentage points, to 40%.
The project, with Yeniköy Kemerköy Elektrik Üretim ve Ticaret A.Ş. is the latest example of GE’s commitment to modernizing coal-fired power plants and generation equipment around the globe.
The upgrade solutions will extend the lifetime of the power equipment by 20 years and significantly lower emissions at the two power plants to meet country’s emission limits, including:
- A decrease in NOx emissions to less than 200 mg/Nm3 (600 mg/Nm3 today).
- A reduction in particulate matter emissions to less than 40 mg/Nm3 (50 mg/Nm3 today).
- A curtailment in SOx emissions to less than 320 mg/Nm3 (1000 mg/Nm3 today).
By bringing together cross-business expertise and technologies, GE’s Powering Efficiency COE can apply a total plant hardware and software solution approach, in turn boosting the efficiency of the world’s new and existing coal-fired power plants and significantly reducing their emissions.
