Wind Energy Project Delays in Turkey: Compensation, Delay Claims and Contractual Remedies (2026)

Learn how foreign investors can recover compensation for delayed wind energy projects in Turkey. This 2026 legal guide explains EPC delays, turbine delivery disputes, grid connection delays, force majeure, liquidated damages, arbitration, and contractual remedies.

Turkey continues to attract substantial investment in onshore and hybrid wind energy projects due to its expanding renewable energy market, strategic location, and long-term energy transition policies. International developers, infrastructure funds, lenders, turbine manufacturers, and independent power producers frequently participate in Turkish wind projects through Engineering, Procurement and Construction (EPC) contracts, turbine supply agreements, operation and maintenance agreements, and project finance structures.

Despite the sector’s growth, project delays remain one of the most common causes of commercial disputes. Even a delay of several months may result in significant financial losses, including increased financing costs, postponed commercial operation dates, lost electricity revenues, additional construction expenses, contractual penalties, and disputes among project stakeholders.

For foreign investors, understanding the legal consequences of project delays is essential. Turkish law provides contractual and statutory remedies, but successful recovery depends largely on the wording of the project agreements, the allocation of project risks, and the quality of the documentary evidence.

This 2026 guide explains the principal legal issues surrounding delayed wind energy projects in Turkey and the remedies available to foreign investors.

---

Types of Delay

Not every delay creates liability.

The most common categories include:

Contractor Delay

The EPC contractor fails to perform according to the contractual schedule.

Employer Delay

The project owner delays payments, approvals, access to the site, or required decisions.

Third-Party Delay

Government authorities, utility operators, municipalities, or landowners cause delays.

Concurrent Delay

Both parties contribute to the delay simultaneously.

The legal consequences differ significantly depending on which party bears responsibility.

---

Delay in Turbine Delivery

Wind turbines represent the most valuable component of most wind projects.

Delivery delays may result from:

• Manufacturing shortages
• Export restrictions
• Port congestion
• Shipping disruptions
• Customs inspections
• Sanctions
• Component shortages
• Transportation permits

Where the supplier assumed delivery obligations under the contract, the employer may seek contractual remedies.

---

Grid Connection Delays

Commercial operation cannot generally commence until the project is successfully connected to the electricity network.

Grid-related delays may involve:

• Connection approval
• Transmission line completion
• Substation construction
• Protection systems
• Technical testing
• SCADA integration
• Meter installation
• TEİAŞ coordination
• Distribution company approvals

Responsibility depends on the allocation of contractual obligations.

---

Permit and Regulatory Delays

Wind farms require numerous governmental approvals.

Potential sources of delay include:

• Environmental approvals
• Zoning decisions
• Forestry permits
• Treasury land permissions
• Expropriation procedures
• Aviation approvals
• Military opinions
• Cultural heritage reviews
• Municipality permits

Contracts should specify which party bears responsibility for obtaining each approval.

---

Delay Liquidated Damages

Most EPC contracts include liquidated damages for late completion.

These provisions commonly establish:

• Daily compensation
• Weekly compensation
• Maximum liability cap
• Completion milestones
• Commercial operation date
• Extension of time procedure

The employer should determine whether delay liquidated damages constitute the exclusive contractual remedy or whether additional losses may also be claimed.

---

Extension of Time Claims

Not every delay entitles the employer to compensation.

The contractor may request an extension where delays result from:

• Employer instructions
• Design changes
• Force majeure
• Regulatory actions
• Unexpected site conditions
• Archaeological discoveries
• Utility relocation
• Extreme weather

The extension procedure usually requires timely written notice.

Failure to comply with contractual notice provisions may result in loss of entitlement.

---

Concurrent Delays

Concurrent delay occurs when both parties contribute to project delay.

Examples include:

• Late employer approvals combined with contractor inefficiency
• Grid delays occurring simultaneously with construction delays
• Employer design changes during contractor shortages

Allocation of responsibility depends upon:

• Contract wording
• Critical path analysis
• Expert evidence
• Project records

---

Critical Path Analysis

Large wind disputes frequently require delay analysis.

Experts evaluate:

• Original project schedule
• Updated schedules
• Progress reports
• Milestones
• Site records
• Daily reports
• Weather records
• Procurement records
• Engineering revisions

Critical path analysis often determines which party actually caused project delay.

---

Performance Bonds

Foreign investors usually require:

• Performance guarantees
• Advance payment guarantees
• Retention guarantees
• Parent company guarantees

Where delays constitute contractual default, these guarantees may become enforceable.

However, wrongful calls may themselves generate litigation or arbitration.

---

Milestone Payment Disputes

Most EPC contracts divide payments into milestones.

Disputes commonly concern:

• Mechanical completion
• Turbine delivery
• Foundation completion
• Grid connection
• Energisation
• Commercial operation
• Final acceptance

The contractor may claim payment while the employer argues that milestone requirements remain unsatisfied.

---

Cost Overruns

Project delays frequently generate additional costs including:

• Crane rental
• Labour
• Accommodation
• Security
• Equipment storage
• Insurance
• Financing
• Currency fluctuations
• Material price increases

Whether these costs are recoverable depends upon contractual risk allocation.

---

Financing Consequences

Project finance agreements usually assume completion by specified dates.

Delay may trigger:

• Increased interest
• Additional equity contributions
• Loan defaults
• Extension fees
• Reduced returns
• Refinancing requirements

The employer may seek compensation where contractor delay causes these financial losses.

---

Lost Electricity Revenue

Late commercial operation frequently results in lost revenue.

Potential losses include:

• Electricity sales
• Renewable support mechanisms
• Capacity revenues
• Corporate power purchase agreements
• Carbon credit opportunities

Recovery depends upon:

• Contract wording

• Proof of loss
• Limitation of liability clauses

---

Force Majeure

Force majeure provisions frequently address:

• Earthquakes
• Floods
• War
• Terrorist attacks
• Government embargoes
• Sanctions
• Pandemics
• Exceptional weather

A contractor invoking force majeure must normally satisfy contractual notification requirements.

Not every commercial difficulty qualifies as force majeure.

---

Contractor Default

Persistent delay may constitute material breach.

Examples include:

• Abandonment of works
• Failure to mobilise
• Failure to supply turbines
• Failure to achieve milestones
• Repeated defective work

The employer may have the right to:

• Terminate the contract
• Replace the contractor
• Recover completion costs
• Claim damages

---

Employer Default

Contractors also possess legal remedies where delay results from employer conduct.

Examples include:
