What IGDAS does

IGDAS (İstanbul Gaz Dağıtım A.Ş.) is the licensed natural gas distribution operator for Istanbul, Turkey, operating as a regulated monopoly under the supervision of EPDK (Energy Market Regulatory Authority). Founded in 1986 and headquartered in Istanbul, the company distributes natural gas to approximately 16 million residents across all 39 districts of the city through an extensive pipeline network totaling 25,932 km — comprising 2,208 km of steel pipeline, 17,980 km of polyethylene pipeline, and 5,744 km of service lines. IGDAS operates 41 service branches organized into three regional customer service divisions (Avcılar, Sultangazi, and Sancaktepe), supported by a call center (153), a 24/7 gas emergency hotline (187), joint payment points with ISKI, partner bank payment channels, and digital self-service infrastructure including an Android mobile application and online customer portal.

The company's product portfolio centers on regulated natural gas distribution, with revenue generated through three primary streams: usage-based distribution tariffs (including a tiered/stepped tariff for residential consumers), one-time connection/subscriber fees, and meter-related services. Additional value-added services include the Sabit Ödeme Sistemi (Fixed Payment System) for smoothing seasonal heating costs, digital invoicing, internal installation certification oversight, and Serbest Tüketici Satış (Free Consumer Sales) supporting Turkey's liberalized wholesale gas market. IGDAS serves residential, corporate, and certified EPDK-licensed installation firm segments, with customer segments split between individual household subscribers and non-residential commercial/industrial users.

Others

Not a direct competitor but a closely adjacent municipal infrastructure operator sharing regulatory and customer channels with IGDAS.

Broad incumbents

• SOCAR Turkey: Azerbaijani state energy company's Turkish operations spanning refining, petrochemicals, and gas trading. Comparable as a major Turkish energy player, but operates across the full gas value chain rather than localized distribution like IGDAS.
