In 1997, a partnership between ENKA by 40% and InterGen by 60% was awarded by the General Directorate of Turkish Electricity (TEAŞ) and the Ministry of Energy and Natural Resources to carry out the turnkey construction and operation of three natural gas combined cycle power plants in Gebze, Adapazarı and İzmir with a total installed capacity of 3,830 MW under the Build-Own-Operate (BOO) scheme.

The turnkey construction of the Gebze, Adapazarı and İzmir natural gas combined cycle power plants was awarded to the BechtelENKA Joint Venture (BEJV), in which ENKA had a 50% share. The projects were launched in 2000. The Gebze and Adapazarı plants were commissioned in 2002 and the İzmir plant in 2003. Thus ENKA, together with its partner InterGen, become the largest private sector electricity producer in Türkiye.

During operation period, ENKA acquired the shares of its partner InterGen and became the sole owner of the power generation companies. The ENKA power plants generated circa 450 billion kilowatt-hours of electricity during the 16 year period of operation. The Electricity Sale Agreements and the Natural Gas Sale Contracts expired at the end of the BOO period.

Following the BOO period, the power plants have been issued generation licenses and commenced operation in the merchant electricity market.

In 2021, the ENKA power plants have generated circa 10.5 billion kWh of electricity. With an annual production capacity of 32 billion kilowatt-hours, ENKA power plants have the potential to meet 10% of Türkiye’s total energy consumption.
