The Greek government has approved a cadastral study for underground power cable infrastructure that will connect the new Heraklion International Airport to the electrical grid. Dated March 30, 2026, the decision authorizes the establishment of a servitude (legal right) for cables needed to construct and operate a 150kV high-voltage transmission line.
The project aims to provide electrical interconnection for the new international airport of Heraklion, Crete, with the infrastructure to be installed in the Kastelli area within the Minoa Pediad municipality of Heraklion prefecture.
What is a cadastral study?
A cadastral study is a preliminary legal and technical assessment that identifies property parcels affected by a proposed infrastructure project. In this case, the study determines which land parcels require a servitude - a legal right that allows utility cables to pass underground through private or public property. This approval is an essential step before construction of the power transmission line can proceed.
The 150kV transmission line
The 150kV transmission line represents major electrical infrastructure required to support the new airport's operations. High-voltage transmission lines like this carry power efficiently across longer distances before stepping down to lower voltages for local distribution. The underground installation through the Kastelli area protects the cables from weather and minimizes visual impact on the landscape.
Impact on property owners
For property owners in the Kastelli area, this decision means that a servitude may be established on their land to allow cables to pass underneath. Servitudes typically grant utility companies the right to access the cables for maintenance and repairs, and property owners retain most uses of the land above the cables.
Infrastructure progress
The approval of the cadastral study is a procedural milestone in a larger infrastructure project supporting Crete's new airport. The study establishes the legal framework and identifies affected properties, enabling the subsequent phases of design, permitting, and construction. This reflects the Greek government's commitment to completing electrical infrastructure necessary for the airport's full operational capacity.
For travelers and visitors, reliable electrical infrastructure is foundational to the airport's functioning. The power transmission system ensures adequate capacity for lighting, climate control, baggage handling, security systems, and all other airport operations. As Crete's tourism industry depends on airport capacity and reliability, these infrastructure upgrades support the island's continued growth as an international destination.
The decision represents progress on a critical piece of Crete's transportation and energy infrastructure. Once the power connection is operational, it will be essential to the new Heraklion airport's ability to serve international passengers and support the island's economy.
