EPİAŞ (Energy Exchange Istanbul) is Türkiye’s sole authorized energy exchange, operating power, natural gas and environmental markets. Established on March 18, 2015 under the Turkish Electricity Market Law and licensed by the Energy Market Regulatory Authority (EMRA), EPİAŞ has become a cornerstone of Türkiye’s liberalized energy sector. In 2025, the company marks its 10th anniversary, celebrating a decade of advancing transparent, competitive and secure market operations.
EPİAŞ operates a broad range of energy markets and mechanisms that ensure efficiency, trust and reliable price formation, including the Day-Ahead and Intraday Spot Power Markets, Power and Natural Gas Futures, the Spot Natural Gas Market, the Renewable Energy Guarantees of Origin (YEK-G) System and the Organized YEK-G Market. In addition to these, it administers the Renewable Energy Resources Support Mechanism, manages financial settlement, collateral management and invoicing across power and gas markets and eligible consumer switching.
Following the recent enactment of Türkiye’s Climate Law in July 2025, EPİAŞ was designated as the market operator for the national Emissions Trading System (ETS) Markets, placing the company at the forefront of Türkiye’s climate policy and the country’s transition to a low-carbon economy.
All market and service software is developed in-house, reflecting EPİAŞ’s strong commitment to digitalization, operational reliability and market integrity. The Transparency Platform provides market participants with reliable and timely data, reinforcing trust in price signals and market outcomes.
