Introduction
In recent years, the global shift toward renewable energy has positioned solar energy as one of the most promising resources. In Turkey, legislative changes have made solar power plant (SPP) installations more accessible, especially through the concept of unlicensed electricity production. Governed primarily by the Electricity Market Law (Law No. 6446), the Unlicensed Electricity Production Regulation, and directives from the Energy Market Regulatory Authority (EPDK), these frameworks provide investors and individuals with the ability to produce electricity for their own use or for the grid without undergoing the burdensome licensing process.
This article examines the legal foundations, application procedures, practical implementation, and challenges related to unlicensed solar power plant installations. It offers a comprehensive analysis of both theoretical regulations and real-world practices, aiming to serve as a legal roadmap for prospective investors and project developers.
1. Legal Framework for Unlicensed Solar Power Production
The unlicensed electricity generation model in Turkey was first introduced with the amendments to Law No. 5346 and further developed under Law No. 6446. This model was designed to:
- Promote small-scale renewable energy production,
- Encourage self-consumption and decentralized energy systems,
- Provide a simplified regulatory structure compared to licensed generation.
The main legal sources regulating unlicensed solar energy production include:
- Law No. 6446 on the Electricity Market (especially Article 14),
- Unlicensed Electricity Production Regulation,
- Renewable Energy Law (Law No. 5346),
- EPDK Board Decisions and Implementation Guidelines,
- Environmental Impact Assessment (EIA) Regulation, and
- Grid Connection Procedures by TEİAŞ (Turkish Electricity Transmission Company) and distribution companies (EDAŞ).
2. Scope and Key Principles of Unlicensed Solar Production
Unlicensed production allows electricity generation facilities with a capacity up to 5 MW (as per recent regulations) to be connected to the grid without requiring a formal generation license or forming a separate legal entity dedicated solely to energy production.
Key Principles Include:
- Self-Consumption Priority:
The primary aim is to cover the producer’s own electricity needs, with any surplus being sold to the grid. - Net Metering & Billing:
Surplus electricity is offset against the consumption, and excess is sold at market price or under incentives, such as YEKDEM. - Connection to Local Distribution Networks:
Unlicensed SPPs are generally connected to the nearest distribution grid, ensuring localized energy production. - Simplified Administrative Process:
Compared to licensed projects, there is no need for an EPDK generation license or competitive bidding, which significantly reduces legal and bureaucratic burdens.
3. Application and Implementation Process
The process of setting up an unlicensed solar power plant involves several legal and technical steps, which can be summarized as follows:
3.1. Preliminary Feasibility and Site Selection
- Land Ownership: The investor must own or lease the land where the SPP will be installed. Title deed and zoning status are critical. Agricultural or forest lands may require additional permits from the Ministry of Agriculture or Forestry.
- Solar Potential Analysis: Feasibility studies, including irradiation data and technical evaluations, should be conducted to ensure the financial viability of the project.
3.2. Application to the Distribution Company
- Application File: Investors must submit a comprehensive application to the local distribution company (EDAŞ). The file generally includes:
- Project description and technical drawings,
- Single-line electrical diagram,
- Connection point proposal,
- Proof of land rights (title deed or long-term lease),
- Environmental documents (EIA exemption or positive opinion if applicable).
- Capacity Evaluation: EDAŞ evaluates whether the regional grid has enough capacity to accept the new solar plant.
3.3. Grid Connection Agreement
Once the application is approved, a connection agreement is signed with EDAŞ. The investor must:
- Pay the connection fees,
- Complete technical compliance tests,
- Install grid-compatible inverters and protection systems.
3.4. Construction and Acceptance Process
- Construction must start within the timeframe specified by the distribution company (typically within 12 months).
- After construction, the TEDAŞ acceptance test is performed to ensure the plant meets all technical standards.
3.5. Commercial Operation and Metering
- A bi-directional meter is installed for net metering.
- Any surplus energy fed into the grid is recorded and compensated monthly.
4. Incentives and Financial Advantages
Unlicensed solar power producers benefit from various incentives:
- YEKDEM Support: Surplus electricity from renewable sources is purchased at a fixed tariff (USD 0.133/kWh for solar energy under Law No. 5346).
- Tax Advantages: Unlicensed producers can benefit from VAT exemptions on the sale of surplus energy.
- Local Equipment Incentives: Additional premiums (USD 0.4-3.5 cents/kWh) are provided for projects using certified domestic equipment.
5. Environmental and Zoning Requirements
Even though the unlicensed model simplifies administrative steps, certain environmental and zoning requirements still apply:
- EIA Exemption: Projects under 1 MW are generally exempt, but a formal “No EIA Required” letter must still be obtained.
- Zoning Plan Amendments: If the land is classified as agricultural, investors must obtain conversion permits or special approvals.
Failure to comply with these environmental regulations can lead to administrative fines or cancellation of the connection agreement.
6. Legal Challenges and Risk Management
Unlicensed solar investments, despite their benefits, may face challenges such as:
- Grid Saturation: Certain regions have no available capacity, leading to application rejections.
- Land Ownership Disputes: Title deed issues or overlapping rights can delay the project.
- Regulatory Changes: Amendments to Law No. 6446 or EPDK regulations may impact tariffs or capacity limits.
- Force Majeure and Delays: Delays in construction or acceptance tests can result in loss of incentives.
Practical Tip: Before investing, conducting a legal due diligence on land rights, zoning status, and connection capacity is crucial. Additionally, drafting solid EPC (Engineering, Procurement, Construction) contracts and O&M (Operation and Maintenance) agreements mitigates operational risks.
7. Practical Case Study: Small-Scale Solar Installation
Consider a commercial building with an annual electricity consumption of 1,000,000 kWh. By installing a 1 MW rooftop solar system under the unlicensed framework:
- The building can offset nearly 70% of its annual consumption.
- Surplus electricity fed into the grid is sold to the market operator (EPİAŞ) at a guaranteed rate.
- Payback periods for such projects, with YEKDEM incentives, typically range between 5-7 years.
This illustrates how unlicensed solar production supports energy independence and cost savings while maintaining legal compliance.
8. Future Outlook
The Turkish government aims to increase the share of renewable energy in total electricity production. The expansion of unlicensed generation—especially rooftop and small-scale solar—plays a key role in achieving this target. Regulatory authorities are continuously revising procedures to:
- Facilitate rooftop solar projects for households and SMEs,
- Introduce energy storage requirements alongside solar installations,
- Improve digital metering and grid integration technologies.
Conclusion
Unlicensed production regulations in solar power plant installations have revolutionized renewable energy investments in Turkey. By removing licensing barriers, simplifying bureaucratic processes, and providing financial incentives, the regulatory framework has made solar energy accessible to a wide range of investors. However, a successful project requires careful legal planning, due diligence, and compliance with environmental and zoning rules.
As the sector continues to evolve, staying informed about regulatory updates and engaging expert legal and technical consultants will be key to leveraging these opportunities.
