Azerbaijan starts Zangezur power transmission line construction

Construction has begun on the Zangezur power transmission line, a landmark project designed to connect the Nakhchivan Autonomous Republic to Azerbaijan’s main electricity grid, the AzerEnergy press service reported.

AzerEnergy is spearheading the effort, building a high-voltage 330-kilovolt double-circuit line capable of transmitting 1000 megawatts.

The line will stretch 74 km from Jabrayil to Aghband and run parallel over 105 km from Nakhchivan to the Ordubad border, cutting through challenging mountainous and rocky terrain along the Araz River.

The next phase of the project will see an additional 44-km line crossing the Zangezur corridor, connecting to the existing infrastructure toward Aghband and Ordubad. In Nakhchivan city, a new 330 kV substation is under development, with 49 hectares of land already mobilized to support construction.

Looking ahead, the Azerbaijan-Türkiye-Europe energy corridor will expand further with a transmission line linking Nakhchivan to Türkiye, including the country’s first 400 kV-class converter substation, an unprecedented milestone for Azerbaijan.

Considered one of the largest and most strategic energy initiatives in Azerbaijan’s history, this project not only fully integrates Nakhchivan into Azerbaijan’s national electricity system but also removes the region’s reliance on foreign frequency regulation and opens the door to European energy markets.
