A significant part of the first generation unlicensed solar power plants in Turkey were established with a USD-based purchase guarantee according to the legislation before May 10, 2019. "What will happen when the ten-year YEKDEM / support period expires?" The question was answered in two branches in 2026: (1) surplus sales price - Presidential Decree No. 11415; (2) upstream distribution fee — EMRA's transition from Unlicensed Producer-1 to Unlicensed Producer-2 (approximately 208 krş/kWh → 65.6 krş/kWh). This article combines both branches into one road map; It should be read with the logic of net income = sales price − distribution fee ± hourly offset.

Who is affected? USD guaranteed / pre-2019 portfolio
Decision no. 11415; Law No. 6446 art. It covers facilities that are in unlicensed production within the scope of Article 14, whose 10-year period of being subject to YEKDEM has ended, and which continue to be unlicensed. In practice, this is the first wave portfolio (sector briefs), specifically in the ~800 installations / 500–550 MW band established in the USD guaranteed period with call letter / commissioning before 10 May 2019 and completing the decade by 2026. The decision does not automatically convert facilities to licensed; It clarifies how the surplus will be sold and how many TL/kWh will be purchased if it remains unlicensed.
Sales price: 90% YEKDEM ≠ warranty — maximum hourly PTF
The purchase price for the surplus given to the system after hourly clearing is calculated as follows: 90% of the current YEKDEM price applied on the basis of facility type for licensed production facilities (two digits after the decimal point). This value cannot exceed the Market Clearing Price (PTF) of that hour. Correct reading: Not “90% YEKDEM guarantee”; It is a 90% YEKDEM model with PTF ceiling. At noon, when solar power generation is intense and MCP is under pressure, the ceiling MTF becomes decisive — income projection cannot be made only with monthly YEKDEM.
| Clock type | 90% YEKDEM (example) | Hourly PTF (example) | Applied intake |
|---|---|---|---|
| PTF high | 2.50 TL/kWh | 3.20 TL/kWh | 2.50 (formula) |
| PTF low (noon) | 2.50 TL/kWh | 1.80 TL/kWh | 1.80 (PTF ceiling) |
| PTF ≈ formula | 2.50 TL/kWh | 2.45 TL/kWh | 2.45 (ceiling) |
- The assigned supply company is obliged to purchase the energy that can be sold.
- The purchased energy is deemed to be produced and supplied to the system by the authorized supplier within the scope of YEKDEM.
- In our Hourly Settlement 2026 guide, the definition of surplus after offset is; In this article, a 10-year price layer is added.
Same measurement vs different measurement — how much will sell?
| structure | Sales scope | 2026 note |
|---|---|---|
| Same measuring point (e.g. roof 5.1c) | All electricity produced can be sold | The decision is clear |
| Different measuring point (e.g. 5.1h) | Surplus; quantity rule was left to EMRA | 14671: Can be sold entirely in 2026 |
| Above EMRA amount | Free contribution to YEKDEM | no payment |
With EMRA's decision numbered 14671 dated June 18, 2026, the sale of all surplus in 2026 was allowed for facilities that have completed 10 years at different measurement points — the message of "no sales restrictions" for that year. In the following years, it is necessary to follow the EMRA quantity methodology. The choice of power plant type (5.1c / 5.1h) affects both settlement and sales volume in feasibility and operation.
Distribution fee: Unlicensed Producer-1 → Producer-2 (208 → 65.6 krş)
USD guaranteed / early stage unlicensed facilities remained in the Unlicensed Producer-1 band in upstream distribution for a long time; The unit price was 208.1065 kuruş/kWh. During hours when PTF was below this price, the supply to the grid was not economical and there was a risk of production restriction. With the decision numbered 14613 dated 21 May 2026, EMRA reduced the upstream distribution fee to the Unlicensed Producer-2 tariff as of 1 June 2026 for facilities that have completed 10 years: 65.6008 kuruş/kWh (~68% decrease). This framework was made permanent with decision no. 14681. Detailed cost tables are in our Distribution Cost for Unlicensed Solar Power Plants Over 10 Years guide.
| pencil | Unlicensed Producer-1 | Unlicensed Producer-2 |
|---|---|---|
| delivery cost | 208.1065 krs/kWh | 65.6008 krş/kWh |
| Approximately TL/kWh | ~2.08 TL | ~0.66 TL |
| Who? | Application 10 years ago | Mature facility that has completed 10 years |
| basis | Previous tariff | EMRA 14613 → 14681 |
Operation: why is hourly follow-up necessary?
- PTF ceiling is hourly jobs; Income calculation with monthly average YEKDEM is incorrect.
- After clearing, the surplus must be verified with hourly LLM / OSOS.
- If the delivery kWh × LÜ-2 price and the sales revenue are not clarified in the same panel, the margin will not appear.
- For facilities remaining from the USD guaranteed period, the tariff class (LU-1 vs LÜ-2) should be checked separately in the invoice reconciliation.
ENOPTIMAL — Income tracking after 10 years
ENOPTIMAL production and settlement module; It monitors hourly production-consumption, surplus, PTF and distribution cost items together. The “sales unit × delivery kWh − LÜ-2 distribution” scenario in the portfolio that has completed 10 years should not be confused with the old high distribution price assumption. Live production in our SPP production monitoring module; Paid limit (facilities that have not yet completed 10 years) is a complementary reading in our unlicensed solar energy sales guide.
Conclusion
Decision numbered 11415 linked the sale of surplus in unlicensed (especially USD guaranteed / pre-2019) facilities that have exceeded 10 years to the 90% YEKDEM model with PTF ceiling. In the same measure, the sales opportunity is clear; In different measurements, it can be sold completely for 2026 (14671). In parallel, withdrawing the distribution fee from Unlicensed Producer-1 to Producer-2 (208.1 → 65.6 krş/kWh) is the cost side that saves the net margin. Watch both together, hourly — our article, Hourly Settlement Roadmap for Eligible Consumers, is complementary to the eligible consumer intersection.
