Hamitabat Electricity Generation and Trade (HEAŞ) has significantly enhanced the efficient use of the country’s natural resources and reduced energy import costs by increasing efficiency to 61% through a EUR 520 million modernization investment.
With its strategic location, high reliability, and operational readiness, HEAŞ serves as a cornerstone of energy supply in the Marmara Region. In 2018, the company increased its installed capacity to 1,220 MW. Net electricity production reached 5.871 billion kWh in 2025.
In 2025, 14,345,000 cubic meters of embankment construction were completed, along with the spillway, the transmission tunnel intake structure, the shaft structure, 908 meters of transmission tunnel, and the conduit and the outlet structure of the water intake tunnel. These works enabled the commencement of water retention operations, and an application for provisional acceptance has been filed.
As a result of water recovery initiatives, 92,000 cubic meters of demineralized water were recovered in 2025. HEAŞ obtained ISO 46001 Water Efficiency Management System certification in August 2025, becoming the first power plant in Türkiye to receive this certification. These efforts resulted in a 30% water recovery rate.
HEAŞ completed 2025 with zero lost-time injuries. To promote awareness of occupational health and safety standards among all on-site stakeholders, training was delivered through the “visit.hamitabat” online platform, developed in collaboration with Limak Technology. In addition, all suppliers visiting the site received training on occupational health and safety.
To reduce its carbon footprint and meet internal energy needs through renewable sources, a 9.4 MWp solar energy system-established with a EUR 7 million green loan provided in partnership with ING European Financial Services PLCwas commissioned on August 29, 2025. The solar power plant generated 3,334 MWh of net electricity in 2025. The manufacturing of a 730 MVA backup transformer was completed in 2025, and the transformer was prepared for delivery to the power plant. Major Maintenance for Units 10 and 20 is scheduled for completion in 2026. The commissioning of the solar power system contributed to the avoidance of 2,126.36 tons of CO2e emissions in 2025.
HEAŞ supports educational initiatives targeting middle school, high school, and university students. In 2025, events such as career days, industry meetings, and World Environment Day were organized to engage and educate students.
Operating as a symbol of Kırklareli since 1986 and as the first natural gas combined-cycle power plant in the history of the Republic, HEAŞ aims to maintain its presence in the Turkish energy market with a focus on high efficiency, social impact, and environmental responsibility.
