Türkiye’s Ministry of Energy and Natural Resources has revised the technical assessment process for applications involving electricity generation from wind resources. The amendment, published in the Official Gazette on October 3, 2026, introduces more detailed rules covering overlaps between proposed plant sites and other energy projects, the accuracy of application documents, turbine specifications and the transfer of land coordinates into the official evaluation system. The provisions affect both unlicensed generation applications and requests to modify technical details in preliminary or full generation licenses.
The definition of incompatible areas is broader
One of the central changes is an expanded definition of areas considered incompatible during technical review. The amended framework revisits how proposed wind sites are assessed in relation to existing or planned wind, solar, biomass and geothermal power facilities, as well as areas designated under Türkiye’s Renewable Energy Resource Area program. The aim is to ensure that a new wind project’s footprint is checked more clearly against other renewable-energy developments before it can receive a positive technical assessment.
Rejection grounds for unlicensed projects are clearer
The regulation also specifies the circumstances in which an unlicensed electricity generation application may be deemed technically unsuitable. These include incomplete or incorrect information, a project area intersecting with restricted or incompatible zones, turbines interfering with turbines assigned to other projects, and site boundaries that do not match approved coordinates. A mismatch between the turbine values declared in the application and the relevant turbine type certificate or its annexes can also result in an unfavorable assessment.
Complete data required for modification requests
Requests to change the number or capacity of units, turbine coordinates, plant boundaries, tower height or rotor diameter in a preliminary or generation license must be supported by a complete and accurate information form. This means that a redesign cannot be assessed solely on the basis of a general declaration; it must be backed by technical documentation and verified spatial data. The revised rules also place greater emphasis on consistency between information submitted by developers and land or infrastructure records held by public bodies.
Coordinate documents will be transferred to YEPDIS
Procedures for entering land coordinates into the Renewable Energy Projects Evaluation System, known by its Turkish acronym YEPDIS, have also been updated. Approved coordinate documents for titled land, roads, streams and irrigation canals are to be uploaded by the relevant grid operators. These records are intended to help reviewers identify whether a proposed plant site conflicts with ownership boundaries, transport corridors or water infrastructure. Discrepancies between an applicant’s site information and officially approved coordinates may lead to a negative technical finding.
What changes for project developers?
The new framework focuses on technical accuracy and site compatibility rather than announcing additional wind capacity, subsidies or a new auction. For developers, the practical message is that turbine certificates, project boundaries, land documents and possible interactions with neighboring energy projects will need to be checked more carefully before an application is filed. Assessments will continue to be carried out through the ministry’s technical system in coordination with the relevant grid operators.
The amendment updates the regulatory framework used to review wind projects in Türkiye, but it does not by itself approve or reject any individual facility. Each application will still be decided on its own technical record. The significance of the change lies in making the documentation and spatial-review requirements more explicit, which may reduce ambiguity while increasing the preparation burden for applicants whose technical or coordinate data are incomplete.
