POWER GENERATION

ENKA POWER GENERATION

ENKA’s legacy in power generation is built on landmark projects such as the Gebze, Adapazarı, and İzmir natural gas combined cycle power plants, all fully owned and operated by ENKA under the Build-Own-Operate (BOO) model. With a total installed capacity exceeding 4,000 MW from the power plants and an annual electricity generation capacity of 32 billion kWh, ENKA stands as Türkiye’s largest private electricity producer, capable of meeting approximately 10% of the country’s total energy demand.

The Electricity Sales Agreements and Natural Gas Supply Contracts for the power plants reached their expiration at the end of the BOO period in 2019. Following the BOO period, the power plants obtained generation licenses and commenced operations within the merchant electricity market, continuing to play a vital role in ensuring the country’s energy supply through competitive and reliable power generation. Furthermore, the Energy Market Regulatory Authority (EPDK) has issued ENKA Enerji Ticaret A.Ş. with an electricity supply license and a natural gas import (spot market) license. These licenses empower ENKA to participate in wholesale or retail activities in both electricity and gas markets.

In 2024, the ENKA power plants generated 2.8 billion kilowatt-hours of electricity, contributing to a cumulative total of over 467.8 billion kilowatt-hours throughout their operational history.

In response to Türkiye’s growing energy demands, ENKA has initiated a new investment for the development of a state-of-the-art natural gas combined cycle power plant in Kırklareli. This strategically important project underscores ENKA’s ongoing commitment to strengthening national energy security by delivering high-efficiency, high-capacity power generation solutions that support grid reliability and sustainable growth.

ENKA recognizes the vital role renewable energy plays in building a sustainable future and is committed to becoming a leading force in the dynamic global energy sector. As ENKA expands its presence across international markets, the company is making decisive progress toward a cleaner, low-carbon future. A key example of this commitment is the Kameno Solar Photovoltaic Power Plant in Bulgaria — a project developed entirely through ENKA’s own investment. This initiative reflects the company’s strategic focus on advancing renewable energy solutions and underscores its dedication to expanding sustainable energy sources while helping shape the future of clean power generation.

KIRKLARELİ GAS FIRED COMBINED CYCLE POWER PLANT

850 MW

As part of efforts to support Türkiye’s growing energy infrastructure, ENKA Kırklareli Elektrik Üretim A.Ş. has undertaken the construction of the Kırklareli Natural Gas Combined Cycle Gas Turbine Thermal Power Plant with a nominal capacity of 850 MW, located in Kırklareli city in Türkiye as its own investment. The project commenced in November 2022, and the plant is scheduled for commissioning by the end of 2025.

The power plant is based on 1x1x1 configuration, equipped with one GE 9HA.02 gas turbine and hydrogen cooled generator (H78), one D650 steam turbine and air-cooled generator (A78), one triple-pressure reheat heat recovery steam generator (HRSG) to be supplied by GE, one air-cooled condenser (ACC), one gas-regulating metering station (RMS) and all associated equipment and systems.

The total workforce at the project site exceeded one thousand personnel, reflecting the scale and complexity of the construction effort.

KAMENO SOLAR PHOTOVOLTAIC POWER PLANT

45 MWp

ENKA embraces the critical importance of renewable energy in shaping a sustainable future and is steadfast in its commitment to becoming a leading force in the rapidly evolving global energy sector.

As part of this vision, Town Up 8 LTD, a wholly owned subsidiary of ENKA has developed a 45 MWp Solar Photovoltaic Power Plant in Burgas, Bulgaria. The plant is expected to generate approximately 63 GWh of clean electricity annually, supporting regional decarbonization efforts and reinforcing ENKA’s role in advancing low-carbon energy solutions. Developed as a fully ENKA-financed investment, the project spans a total area of 470,000 m², with commissioning scheduled for late June 2025.

The project includes approximately 80,000 solar panels and 120 inverters for efficient energy conversion. It also involves roughly 1,900 tons of steel structure for panel mounting systems, along with the construction of one Central Electrical Control Building and one Administrative (ESO) Control Building. Additionally, the plant will feature eight compact field transformers and approximately 645 kilometers of solar cabling.

This solar power plant represents only the beginning of ENKA’s journey toward building a robust renewable energy portfolio. It underscores the company’s commitment to supporting the global transition to a cleaner, more resilient, and sustainable energy system.
