Istanbul, Turkey, April 5, 2011 — Using F-technology gas turbines recently upgraded by GE, Turkish company ENKA achieved 99.8 percent global power plant availability over the 12-month period ending November 2010.
ENKA's Adapazari and Gebze generating stations, with a total installed capacity of 2,320 MW powered by GE Frame 9FA+e gas turbines, achieved 99.8 percent availability, which is nearly 7 percent higher than the industry average and a global record in F-class gas turbine technology.
The increase in availability allowed the Adapazari and Gebze plants to generate an additional 1.3 million MWh of electricity, enough to meet the needs of 300,000 households.
The high availability also produced additional income for ENKA and avoided the need to build a new 150-megawatt power plant to meet growing electricity demands.
ENKA worked with GE Energy in 2008 and 2009 to implement an efficiency improvement upgrade called the Cooling Optimization Package on the GE Frame 9FA gas turbines operating at both power plants. As a result of the COP implementation, gas turbine output increased by 2 percent and average combined-cycle efficiency reached 55.7 percent.
The Adapazari and Gebze plants have been delivering continuous power to the Turkish grid at high levels of availability for the last eight years. Between 2002 and 2010, these two plants produced 9 percent of Turkey's total generation.
The GE gas turbines at all of ENKA's plants—Adapazari, Gebze and Izmir—operate under a GE 16-year contractual service agreement. GE's CSAs are structured to provide customers with predictable maintenance costs, while ensuring high availability and a steady revenue flow from power plant operations. To date, GE has long-term service agreements in place at more than 700 sites worldwide.
ENKA is the largest private electricity producer in Turkey and supplies 15 percent of the country's electricity with three plants in Adapazari, Gebze and Izmir.
