Methodology

Data sources

Türkiye’s electricity generation data is obtained from the Transparency Platform of the market operator, EPİAŞ. “Real Time Generation” dataset is used for licensed electricity generation, while the “Unlicensed Electricity Generation” dataset is used for unlicensed electricity generation.

For installed capacity data, the YTBS system of the transmission system operator, TEİAŞ, is used. This dataset may undergo backward corrections. The installed capacity data published in this report reflects the data available in YTBS as of February 17, 2025.

Electricity generation data for European countries has been sourced from Ember’s European Electricity Review. Ukraine is excluded from the rankings of top 20 power consuming European countries due to the suspension of electricity data since the war.

Temperature data for Türkiye is based on measurements conducted by the Turkish State Meteorological Service since 1971.

Calculations for 2030 and 2035 targets

Türkiye’s latest targets announced at COP29 include electricity demand and installed capacity targets for 2030 and 2035. However, the plan does not specify the electricity mix in 2030 and 2035. The 2030 capacity targets presented in the new plan are identical to the capacity targets in the previous official plan. Unlike the latest plan, the previous plan also included electricity generation mix along with capacity targets. In this study, the 2030 electricity generation mix is directly taken from the previous plan. The electricity mix for the newly announced 2035 capacity targets is calculated based on the same capacity factors in the previous plan.
