The Energy Market Regulatory Authority (EPDK) introduced a critical transitional regulation for unlicensed electricity generation facilities that have completed ten years, through Board Decision No. 14613 dated 21/05/2026, published in the Official Gazette dated 23 May 2026. Until a Presidential Decree is issued on the matter, these facilities will be subject to the "Unlicensed Generator-2" tariff class.
When the decision takes effect, the feed-in distribution charge for facilities within this scope will be applied as 65.6008 kr/kWh instead of 208.1065 kr/kWh — approximately a 68% reduction.
What Does the Decision Change?
Solar power plants (SPPs), wind and cogeneration facilities commissioned under the Unlicensed Regulation are entering a transition period as their 10-year YEKDEM-like support window closes. Facilities that have filled this window pay the feed-in distribution charge for each kWh they inject into the grid under a different tariff class.
To eliminate the uncertainty until the Presidential Decree that will determine permanent prices and procedures is issued, EPDK temporarily bound these facilities to the "Unlicensed Generator-2" tariff.
Numerical Impact
The new tariff directly affects cash flow for the on-site generator. The table below summarizes the difference between the two tariffs:
| Tariff Class | Feed-In Distribution Charge |
|---|---|
| Previous application | 208.1065 kr/kWh |
| Unlicensed Generator-2 (new) | 65.6008 kr/kWh |
| Difference | ~142.5 kr/kWh decrease (68%) |
Example Calculation: 1 MW Rooftop SPP
For a typical 1 MWp rooftop SPP producing approximately 1,500 MWh (1,500,000 kWh) per year and injecting most of it into the grid, the annual difference is:
- Previous charge: 1,500,000 × ₺2.081065 ≈ ₺3.12 million/year distribution cost
- New charge: 1,500,000 × ₺0.656008 ≈ ₺984 thousand/year distribution cost
- Annual savings: ~₺2.14 million
The calculation is illustrative; the actual amount varies based on the facility's injection profile, VAT and other components.
Who Is Affected?
- Rooftop and ground-mounted SPPs commissioned in 2014-2016 — facilities completing 10 years this year form the first wave.
- Unlicensed generation facilities set up by industrial consumers for self-consumption and OSB power plants that inject their surplus into the grid.
- Energy cooperatives and corporate structures operating under the prosumer model.
Still Open Questions
- Scope of the Presidential Decree: Whether the permanent price will be set at the "Unlicensed Generator-2" level, or through a different formula, is not yet clear.
- Retroactive application: A separate arrangement is expected for the past period bill reconciliation of facilities that have long since passed the 10-year mark.
- Post-YEKDEM period: As facilities are now outside the support mechanism, they are exposed to market price (MCP) or bilateral contract risk on the sales side.
What Should Plant Operators Do?
- Verify the tariff class. Confirm via your bill that your facility has been switched to the correct tariff class in your distribution company's system.
- Update your settlement reports. Use the new unit charge in your hourly settlement calculations; otherwise your annual cash projection will be higher/lower than reality.
- Prepare for past bill reconciliation. Add a note in your bank/investor reporting for the differences that will arise until the Presidential Decree is issued.
- Optimize your injection profile. The decreased distribution charge improves the economics of injecting surplus generation to the grid; re-evaluate your self-consumption/storage decisions.
The facility-level hourly settlement engine and bill reconciliation module on SmartPlain allow you to apply the new tariff in one click and produce the annual impact as a report. We recommend running these reports periodically to measure the operational impact of regulatory changes.
Frequently Asked Questions
When did the decision take effect?
Board Decision No. 14613 dated 21 May 2026 was published in the Official Gazette dated 23 May 2026; it is implemented in the period following its publication.
Is this decision permanent?
No. The "Unlicensed Generator-2" tariff is a temporary arrangement that will apply until the Presidential Decree on prices and procedures is published.
Is there a change in withdrawal-side charges?
This Board Decision regulates only the feed-in distribution charge. Withdrawal-side charges for the energy consumed by the facility are subject to separate tariff classes.
Are facilities that haven't yet completed 10 years affected?
No. The regulation only applies to unlicensed generation facilities that have completed the 10-year period from the provisional acceptance date.
