Introduction
Geothermal energy is considered a reliable and sustainable energy source that supports global renewable energy strategies. In Turkey, geothermal resources are defined as natural resources of public ownership, and their exploration, use, and operation are strictly regulated under various laws, including Law No. 5686 on Geothermal Resources and Natural Mineral Waters. Investors interested in geothermal energy projects are required to obtain exploration licenses (arama ruhsatı) and subsequently operation licenses (işletme ruhsatı) to legally conduct activities.
This article examines the legal validity of exploration and operation licenses, discussing the legislative framework, licensing procedures, legal disputes, and case studies related to geothermal energy projects. It also provides a practical guide for investors to ensure compliance and avoid legal risks.
1. Legal Framework Governing Geothermal Licenses
Geothermal energy projects are primarily governed by the following legislative sources:
- Law No. 5686 on Geothermal Resources and Natural Mineral Waters,
- Mining Law No. 3213 (where applicable to resource use rights),
- Renewable Energy Law No. 5346,
- Environmental Impact Assessment (EIA) Regulation,
- Regulations of the General Directorate of Mineral Research and Exploration (MTA) and relevant provincial administrations.
1.1. Exploration License
The exploration license grants the exclusive right to explore geothermal resources within a designated area for a specific duration. The license:
- Allows drilling, geophysical surveys, and testing activities,
- Does not grant the right to commercially exploit the resource,
- Is issued for a maximum of 3 years, with the possibility of extension under specific conditions.
1.2. Operation License
Once a commercially viable resource is identified, the investor must apply for an operation license, which:
- Grants the right to extract and use the geothermal resource for electricity generation or direct use (e.g., heating),
- Is valid for 30 years (renewable for additional terms),
- Requires compliance with technical, safety, and environmental regulations.
2. Legal Validity and Conditions of Exploration Licenses
2.1. Application Procedure
Exploration licenses are granted by provincial administrations after reviewing the technical and financial capacity of the applicant. The application requires:
- A technical exploration plan,
- A financial guarantee (typically a deposit or bond),
- Environmental assessments,
- Proof of professional competence.
2.2. Rights Granted by the License
The exploration license holder has the exclusive right to conduct surveys and test drilling within the designated area. However, it does not automatically confer the right to use the resource for commercial purposes.
2.3. Legal Validity
The license is valid only for the specified term and geographic area. Any activity outside these limits (e.g., drilling in unauthorized areas) constitutes an illegal use of geothermal resources, which may result in administrative penalties or revocation of the license under Law No. 5686 Article 17.
3. Transition from Exploration to Operation License
To transition from exploration to operation, the investor must:
- Submit a comprehensive resource report, including drilling results, temperature, and capacity data,
- Obtain EIA approval or exemption,
- Present a technical operation plan to the provincial authority,
- Pay required fees and update financial guarantees.
Failure to apply for an operation license within the exploration term results in loss of priority rights, allowing other investors to claim the field.
4. Legal Disputes and Risk Factors
4.1. Overlapping Licenses
Conflicts often arise when multiple investors claim rights over the same geothermal field. Courts usually prioritize the first validly issued license, provided the holder fulfills all legal obligations.
4.2. Environmental Violations
If exploration activities cause environmental damage (e.g., groundwater contamination), licenses may be suspended or canceled. Law No. 2872 on Environmental Protection imposes strict liability on license holders.
4.3. Non-Compliance with License Terms
Exploration license holders must complete drilling and testing within the prescribed term. Failure to meet deadlines may lead to revocation and forfeiture of deposits.
5. Practical Guidance for Investors
5.1. Due Diligence Before Application
- Verify whether the area is already under license or reserved as a public resource.
- Conduct feasibility and environmental studies prior to submitting the application.
5.2. Contractual and Legal Compliance
- Draft comprehensive contracts with drilling companies and technical consultants, ensuring compliance with Law No. 5686.
- Secure insurance and financial guarantees to cover potential environmental or technical damages.
5.3. Timely Renewal and Reporting
- Submit periodic reports to the provincial administration, including drilling progress and resource analysis.
- Apply for an operation license before the exploration term expires to retain priority rights.
6. Practical Challenges in Operation Licenses
Once the operation license is granted, investors face new legal and practical obligations:
- Royalty Payments: A portion of the revenue is paid to the government as a resource usage fee.
- EIA and Environmental Monitoring: Continuous monitoring and reporting of emissions, re-injection of geothermal fluids, and land restoration are mandatory.
- Third-Party Claims: Local communities may file lawsuits for damage to water resources or agricultural land.
7. Comparative and International Perspective
Many countries, such as Iceland, the US, and New Zealand, also treat geothermal resources as state-owned assets. Internationally, exploration and operation licenses are regarded as revocable administrative permits rather than absolute property rights. Turkey’s legal framework aligns with this approach, balancing public ownership of resources with private investment incentives.
Conclusion
The legal validity of exploration and operation licenses in geothermal energy projects hinges on strict compliance with Law No. 5686 and related regulations. Exploration licenses are temporary rights granting the ability to identify potential resources, while operation licenses grant the legal authority to exploit those resources for commercial purposes.
From both theoretical and practical perspectives, these licenses are not mere formalities but binding administrative permits subject to constant oversight. Investors must therefore conduct thorough legal planning, timely reporting, and environmental compliance to avoid disputes or license revocations.
