Following a Build-Own-Operate (BOO) tender in 1997, ENKA together with its partner InterGen was awarded the right to build and operate the Gebze Power Plant with a nominal capacity of 1,600 MW and the Adapazarı Power Plant with a nominal capacity of 820 MW. ENKA with its joint venture partner Bechtel was the Turnkey EPC contractor for these projects.
ENKA Bechtel Joint Venture’s scope as the EPC contractor covered all the Works including design, engineering, equipment supply, construction, commissioning and putting into operation of these 2 natural gas fired combined cycle power plants.
Over seven thousand workers have participated in the construction of the Gebze and Adapazarı power plants at different times, with peak of 2,220. A permanent technical staff remained behind for Operations and Maintenance. Construction of the Gebze and Adapazarı power plants was completed in 2002.
In that period, meticulous planning and close supervision have enabled ENKA to successfully complete planned maintenance in the shortest times yet achieved for GE 9FA +e machines and also achieve 99.8% availability at the Adapazarı plant, nearly 7 percentage points higher than the industry average, and a global record in F-class gas turbine technology. Considering that performance, Power Magazine selected the Adapazarı plant as one of the award-winning gas-fired top plants in 2011.
Also, Factory Mutual (FM) Global awarded all three power plants the status of “Highly Protected Risk” in recognition of ENKA’s commitment to the reduction of potential losses through a stringent program of risk mitigation and prevention.
Since commercial operation began, ENKA has improved the infrastructure at the plants and invested in state-of-the art technology with the “Advanced Gas Path and DLN2.6+ Upgrade”. With this industry-leading technology, a fuel efficiency was improved, emission footprint was lowered and the operational flexibility and reliability of the power plants were enhanced.
With their collective annual generation capacity of 32 billion kilowatt-hours, they are capable of meeting 11% of Türkiye’s aggregate energy consumption as independent generation companies.
