ENKA POWER

THE NUMBER ONE ELECTRICITY GENERATOR (IPP) IN TURKEY

The story of ENKA power generation began when InterGen-ENKA, a 40%-60% partnership between ENKA and InterGen established in 1997, was contracted 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 Izmir with a total installed capacity of 4,000 MW. The plants were constructed in accordance with the Build-Own-Operate (BOO) model.

The turnkey construction of the Gebze, Adapazarı and Izmir natural gas combined cycle power plants was awarded to the Bechtel-ENKA 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 Izmir plant in 2003. Thus ENKA, became the largest private sector electricity producer in Turkey.

null
At the commencement of commercial operation of the plants, ENKA acquired InterGen’s shares, thereby increasing its stake and becoming the sole owner of the electricity generation companies.
null
The total investment for the three plants was USD 2.04 billion.
null
The Environmental Impact Assessment Report, completed in keeping with the format set by the Ministry of Environment, received the official approval of the Ministry. Since the plants were partly financed through foreign project loans, an additional environmental impact assessment report was prepared for the exclusive review of the export credit agencies in accordance with the environmental guidelines of the World Bank. This report indicated minimum levels of impact and was duly approved. In line with the technology that is commonly employed at natural gas combined cycle power plants around the world today, the Adapazarı, Gebze and Izmir plants operate well within the criteria set by air quality, water pollution and noise control regulations, and they constitute an exemplary group of investments in the field of energy in Turkey.
null
The electricity production companies signed 20-year contracts to purchase natural gas from the Petroleum Pipe – line Corporation (BOTAŞ) and to sell electricity to the Electricity Generation Company (EÜAŞ – previously TETAŞ). As the 20-year period included the project development and construction phases, the contract period was essentially 16 years from the date on which the plants entered into commercial operation. Under the electricity sales agreement, the electricity produced in the plants was sold to EÜAŞ in accordance with an average tariff of USD 4.2 cents per kilowatt-hour. This was made possible by the advanced technology employed in the plants and the low financing costs. The electricity sales price consists of four components: investment costs, fuel costs, fixed operating costs and variable operating costs.
null
Among the four components, the fuel costs item is a pass-through item at a guaranteed level of efficiency, and variations in the price of natural gas are reflected proportionally in the sales price. Accordingly, ENKA does not incur any risk with regard to the price of natural gas.
null
The ENKA Power Plants generated over 440 billion kilowatt-hours of electricity during the 16-year period of commercial operation. Since the expiry of the Electricity Sale Agreements with EÜAŞ and the Natural Gas Sale Contracts with BOTAŞ under the BOO Scheme, the plants have been licensed to operate in the merchant electricity market. With their collective annual generation capacity of 32 billion kilowatt-hours, they are capable of meeting 11% of Turkey’s aggregate energy consumption as independent generation companies.
null
Meanwhile, the Energy Market Regulatory Authority (EPDK) has issued the ENKA power trading company ENKA Enerji Ticaret A.Ş. with an electricity supply license. Under the license, ENKA Enerji engages in wholesale/retail activities for eligible consumers. The EPDK has also issued ENKA Enerji Ticaret A.Ş. with an import (spot market) license. Under this license, ENKA Enerji is able to import natural gas/LNG and to engage in wholesale/retaill activities for eligible consumers.
null
Since commercial operation began, ENKA has improved the infrastructure at the plants and invested in state-of-theart technology with the “Advanced Gas Path and DLN2.6+ Upgrade”. With this industry-leading technology, ENKA Power has improved fuel efficiency, lowered its emission footprint and enhanced the operational flexibility and reliability of the power plants.
