What happened
Türkiye Elektrik İletim AŞ (TEİAŞ) has received authority to use expedited expropriation to secure property needed for the Rumeli Transformer Substation Site Project in Tekirdağ.
The measure is set out in Decision No. 11858, dated 9 October 2026. It refers to Article 27 of Expropriation Law No. 2942 as the legal basis for the land-acquisition process.
The planned Rumeli facility is a 400/154 kV transformer substation. It is designed to connect the 400 kV transmission grid with the 154 kV network, providing transformation between those voltage levels.
The project area is in the Trakya part of Tekirdağ, between the districts of Çorlu and Marmaraereğlisi. The decision concerns real estate falling within the project footprint.
Why it matters
The decision moves the project through a key early infrastructure step: obtaining access to the land on which the substation is planned. For electricity-market participants, the project concerns an asset at the interface between the higher-voltage transmission system and the 154 kV grid.
Substations of this type form the physical connection between networks operating at different voltages. In this case, the stated function is specifically to link the 400 kV system to the 154 kV system.
The available information does not establish when construction will start, when the substation could enter service, or what capacity it will have beyond its stated voltage configuration. It also does not provide further technical detail on associated transmission works.
What to watch next
TEİAŞ and the relevant authorities may publish further information on the properties covered by the process. The decision text cited by Enerji Günlüğü does not identify the number of parcels, their combined area or the owners concerned.
Readers tracking grid development in Tekirdağ should watch for subsequent notices that clarify the project boundary, land-acquisition progress and any timetable for the Rumeli substation.
