ResDelta Grid Carbon Index

Hourly carbon intensity of electricity generation in Türkiye, measured in gCO₂/kWh. Over the latest measured period, the dirtiest five percent of hours are 2,24 times the cleanest five percent.

The absolute annual level is not a proprietary claim. The series is anchored to the Ministry’s official annual factor; the index contributes the hourly shape.

Hourly, source-level Real-Time Generation from EPİAŞ. The published history contains 94,100+ hours and exposes missing source periods rather than filling them silently.

Hourly generation by source is multiplied by documented direct-emission factors and divided by domestic generation. International interconnection is excluded from both numerator and denominator.

Lifecycle emissions are outside scope; this version measures direct CO₂.

The hourly raw series is scaled so the production-weighted 2023 average equals the Ministry’s official 434,0 gCO₂/kWh factor. A new official factor triggers a new methodology version.

Unlicensed solar is absent from the EPİAŞ series, so daytime hours appear dirtier than they are. The largest measured bias is published visibly on the index page.

TSRS Scope 2 reporting, CBAM indirect emissions and hourly YEK-G matching. Users remain responsible for applying the factor to the correct reporting boundary.

Published monthly in the first business week. Method changes increment the version; past releases remain in the archive.

The hourly, monthly, annual and hourly-profile CSV files are free to download.

Electricity Maps also covers Türkiye with live carbon intensity. Its value and ResDelta’s last-twelve-month value are not directly comparable: one is live and includes CO₂-equivalent gases, while ResDelta publishes a period average for direct CO₂.

Their order of magnitude is consistent. ResDelta additionally publishes a full free history, official national-factor reconciliation, a Türkiye-specific versioned method and a generation mix without an unattributed category.
