Can renewable energy producers claim compensation for curtailment in Turkey? Learn your legal rights, compensation options, EMRA regulations, TEİAŞ practices, and administrative remedies in this comprehensive 2026 guide.

Curtailment has become one of the most significant legal and financial risks for renewable energy investors in Turkey. As the installed capacity of solar, wind, hybrid, and battery storage projects continues to grow, grid congestion and operational restrictions have become increasingly common. Electricity generation facilities may be instructed by the grid operator to reduce or temporarily stop generation in order to maintain system security, ensure transmission stability, or prevent network overload.

Although curtailment may be technically necessary under certain circumstances, it can lead to significant financial losses for project owners. Reduced electricity production means lost revenue, decreased return on investment, financing difficulties, contractual disputes, and potential breaches of power purchase agreements (PPAs). Consequently, renewable energy producers often ask whether they are legally entitled to claim compensation for these losses under Turkish law.

The answer depends on the legal basis of the curtailment, the applicable legislation, the relevant grid connection agreements, the electricity market regulations, and the specific facts of each project.

What Is Curtailment?

Curtailment refers to the mandatory reduction or temporary suspension of electricity generation ordered by the transmission or distribution system operator.

Unlike planned maintenance initiated by the producer, curtailment is generally imposed by the grid operator for technical or operational reasons.

Typical curtailment measures include:

• Partial reduction of generation output
• Complete shutdown of generation facilities
• Temporary export limitations
• Connection restrictions
• Grid congestion management
• Emergency system balancing
• Voltage control measures
• Frequency stabilization
• Transmission security operations

---

Why Does Curtailment Occur in Turkey?

The Turkish electricity system has experienced rapid growth in renewable energy investments over the last decade. In certain regions, renewable generation capacity has expanded faster than transmission infrastructure.

Curtailment may therefore occur because of:

• Transmission congestion
• Distribution network limitations
• Transformer capacity shortages
• Voltage instability
• Frequency imbalance
• System security concerns
• Emergency operating conditions
• Planned maintenance works
• Force majeure events
• Unexpected equipment failures
• Grid modernization projects
• Regional overloads

Solar and wind projects located in high-generation regions are generally exposed to higher curtailment risks.

---

Which Authorities Can Order Curtailment?

Depending on the project type and connection level, curtailment instructions may originate from:

• Turkish Electricity Transmission Corporation (TEİAŞ)
• Regional electricity distribution companies
• National Load Dispatch Center
• Regional Load Dispatch Centers
• Other competent electricity market authorities acting within their statutory powers

The legal authority to issue curtailment instructions must always derive from applicable legislation and operational regulations.

---

Is Every Curtailment Decision Lawful?

No.

Although Turkish electricity legislation authorizes certain operational restrictions, every curtailment decision must satisfy the principles of legality, proportionality, necessity, and equal treatment.

Authorities must demonstrate that:

• A genuine technical necessity existed.
• Less restrictive alternatives were unavailable.
• The restriction was proportionate.
• The decision complied with applicable regulations.
• Similar projects were treated equally.
• Operational procedures were correctly followed.

Failure to satisfy these requirements may expose the decision to judicial review.

---

Financial Consequences of Curtailment

Curtailment may cause significant commercial losses, including:

• Lost electricity sales
• Reduced balancing market revenues
• Lost renewable support payments
• Lower PPA income
• Project financing difficulties
• Increased debt service pressure
• Contractual penalties
• Delayed investment recovery
• Reduced project valuation
• Shareholder losses

Large-scale renewable projects may suffer millions of euros in lost revenue if curtailment continues for extended periods.

---

Can Renewable Energy Producers Claim Compensation?

In certain circumstances, yes.

Compensation may become available where:

• The curtailment decision was unlawful.
• Administrative authorities exceeded their legal powers.
• Operational procedures were violated.
• The restriction lacked technical justification.
• Discriminatory treatment occurred.
• Contractual obligations were breached.
• Administrative fault caused financial damage.
• Public authorities acted negligently.

Each claim must be assessed individually based on the specific legal and technical circumstances.

---

Administrative Liability of Public Authorities

Under Turkish administrative law, public authorities may be liable for damages resulting from unlawful administrative acts or defective public services.

If a renewable energy producer suffers financial losses because an authority unlawfully restricted electricity generation, compensation may be sought through administrative proceedings.

The claimant generally needs to establish:

• An unlawful administrative act
• Actual financial damage
• A causal connection
• Supporting technical evidence

---

Contractual Compensation Claims

Apart from administrative liability, compensation rights may arise under:

• Grid connection agreements
• System usage agreements
• Transmission agreements
• Distribution agreements
• EPC contracts
• O&M agreements
• Power Purchase Agreements
• Insurance policies
• Equipment warranties

Each contract should be reviewed carefully to determine how curtailment risks have been allocated.

---

Force Majeure Considerations

Not every curtailment automatically creates liability.

Where generation restrictions result from genuine force majeure events such as:

• Earthquakes
• Floods
• Major cyberattacks
• Nationwide emergencies
• Extraordinary system failures

Compensation may be excluded depending on legislation and contractual provisions.

---

Evidence Required for Compensation Claims

Successful compensation cases depend heavily on technical documentation.

Important evidence includes:

• Curtailment instructions
• SCADA records
• Generation data
• Meter readings
• Dispatch instructions
• Grid operator correspondence
• Financial statements
• Lost production calculations
• Expert engineering reports
• Weather data
• Market price records
• PPA documentation

The stronger the documentary evidence, the higher the likelihood of a successful claim.

---

Expert Reports

Most curtailment disputes require independent expert analysis.

Experts typically evaluate:

• Technical necessity
• Grid capacity
• Transmission conditions
• Alternative operational solutions
• Lost energy production
• Financial damages
• Engineering compliance
• Operational procedures

Technical expert reports frequently play a decisive role in litigation.

---

Administrative Court Proceedings

If compensation cannot be obtained administratively, producers may initiate proceedings before the competent Administrative Court.

The court may examine whether:

• The curtailment decision complied with legislation.
• Administrative discretion was exercised lawfully.
• Technical assessments were accurate.
• Due process was respected.
• Financial damages were correctly calculated.

Where the court finds the administrative action unlawful, compensation may be awarded depending on the facts of the case.

---

Foreign Investors

Foreign renewable energy investors enjoy the same legal protections as domestic investors regarding unlawful administrative actions.

International investors should also consider:

• Investment treaty protections
• Bilateral investment treaties (BITs)
• Contractual dispute resolution clauses
• International arbitration provisions
• Political risk insurance

Large infrastructure projects may involve additional protections under international investment law.

---

Preventing Future Curtailment Risks

Developers should reduce legal risks before construction begins by:

• Conducting detailed grid capacity studies
• Negotiating clear connection agreements
• Reviewing curtailment clauses
• Obtaining technical legal opinions
• Assessing transmission limitations
• Evaluating battery storage integration
• Maintaining comprehensive operational records
• Regularly monitoring regulatory changes

Early legal planning significantly reduces future disputes.
