Amendments to the Regulation on Unlicensed Electricity Generation in the Electricity Market

The Regulation Amending the Regulation on Unlicensed Electricity Generation in the Electricity Market Amendment Regulation came into effect through publication in the Official Gazette dated 25.11.2025 and numbered 33088.

The Amendment Regulation introduces amendments to the Regulation on Unlicensed Electricity Generation in the Electricity Market (Regulation) published in the Official Gazette dated 12.05.2019 and numbered 30772 regarding the transfer of generation facilities, technical evaluation process, priority criteria, connection agreement periods and consumption facility regulations.

Transfer of Generation Facilities

New applications became restricted when production facilities are transferred.

• Except in cases of inheritance and bankruptcy, if the generation facility or facilities are transferred, no new application shall be made under the Regulation for the consumption facility or facilities associated with the said facility.
• Any application for an invitation letter for a connection agreement made in relation to such consumption facility or facilities will be returned without evaluation.
• This provision does not apply where the generation facility and its associated consumption facility are transferred together to the same person, or to transfers between public institutions and organizations and their affiliated entities.

Under the transitional provision introduced to the Regulation, data regarding the generation and consumption facilities subject to transfer shall be notified to the market operator monthly by grid operators. The market operator shall maintain this data in an accessible database. The system will become operational on 15.12.2025.

Expansion of the Scope of the Technical Evaluation Report

Significant changes have been made to the technical evaluation process. Applications based on geothermal and biomass energy, in addition to applications based on wind and solar energy, are now included within the scope of technical evaluation by the General Directorate of Energy Affairs of the Ministry (GDEA).

Procedural Change in the Technical Evaluation Process

Within 10 business days after the application is deemed appropriate, the information in the technical evaluation form will be entered into the Renewable Energy Resources Evaluation and Monitoring System and sent to the GDEA, and the technical evaluation will be completed by the GDEA within 30 days.

New Criteria in Priority Evaluation

Applications based on energy sources other than wind and solar energy may be evaluated regardless of the capacity limits announced by TEİAŞ. For these applications, a positive connection opinion may be given automatically if the technical evaluation is favorable. Priority evaluation is conducted only in case of capacity insufficiency at the same transformer center.

Priorities in the priority evaluation for the connection of generation facilities based on wind or solar energy have changed:

• The generation facility must be at the same metering point as the consumption facility,
• If no invitation letter has been previously issued for the same consumption facility by the applicant, the consumption amount in the last year must be high,
• The contract capacity in the connection agreement must be high.

The calculation method in priority evaluation has been regulated for cases where a new application is made for consumption facilities that have previously received an invitation letter for a connection agreement. The formula used in this calculation has been determined and how to calculate the consumption amount forming the basis for priority evaluation has been clarified.

Under the transitional provision, priority evaluation data shall be notified to the market operator monthly by grid operators and maintained in the database. The system will become operational on 15.12.2025.

Connection Agreement Application

• The periods granted to holders of invitation letters for connection agreements and the periods for acceptance procedures have been reorganized. Additionally, separate period calculations have been introduced for different situations in capacity increase applications.
• Applications made on integrated parcels for the same consumption facility are considered as installed capacity increases. Applications on adjacent parcels by persons who have received an invitation letter for a connection agreement after 12.05.2019 are also evaluated according to the provisions on installed capacity increases.

Consumption Facilities

For persons holding an invitation letter for a connection agreement within the framework of priority evaluation, a requirement has been introduced that the total annual electricity consumption of new consumption facilities to be associated with the generation facility must not be less than the consumption amount forming the basis for the application. If these conditions are not met, the energy generated will be considered as a free contribution to the Renewable Energy Resources Support Mechanism (YEKDEM). The Amendment Regulation adds to the definition of YEKDEM a provision stating that legal entities holding generation licenses engaged in generation activities based on renewable energy resources may also benefit from the support mechanism through aggregators.
