How can foreign energy companies recover unpaid electricity sale receivables in Turkey? A 2026 guide covering bilateral electricity agreements, PPAs, invoices, enforcement proceedings, precautionary attachment, commercial litigation, arbitration, interest and debtor asset recovery.

Turkey’s electricity market creates significant opportunities for foreign generators, suppliers, traders and renewable energy investors. However, electricity sales can also generate substantial receivables, and a counterparty’s failure to pay may quickly expose an energy company to serious cash-flow problems.

The dispute may involve an electricity supplier that has not received payment from a commercial customer, a renewable generator selling electricity under a bilateral agreement, a foreign energy trader dealing with a Turkish counterparty, or a project company seeking payment under a long-term power purchase agreement.

The size of these claims can be substantial. Unlike an ordinary unpaid invoice, an electricity receivable may involve thousands of MWh, variable market prices, imbalance adjustments, YEKDEM components, taxes, settlement corrections and contractual formulas.

For a foreign energy company facing non-payment in Turkey, the central question is:

Should the creditor commence enforcement proceedings immediately, obtain precautionary attachment, pursue mandatory mediation, file a commercial lawsuit or invoke arbitration?

The correct strategy depends on the contract, evidence, debtor’s response and—most importantly—the debtor’s asset position.

What Is an Electricity Sale Receivable?

An electricity sale receivable generally arises when electricity has been supplied or sold but the amount due for that electricity has not been paid.

The underlying relationship can arise from different structures, including:

Bilateral Electricity Sale Agreement

Power Purchase Agreement

Electricity Supply Agreement

Energy Trading Agreement

Corporate PPA

Renewable Energy Offtake Agreement

Commercial Electricity Supply

The legal nature of the claim must be determined from the underlying contractual structure rather than merely from the invoice.

Bilateral Electricity Agreements in Turkey

Eligible electricity consumers can purchase electricity through bilateral agreements with licensed suppliers or generation companies.

For 2026, the eligible-consumer threshold has been set at annual consumption of 500 kWh or more, meaning a broad range of commercial customers may participate in competitive electricity supply arrangements.

For debt-recovery purposes, the bilateral agreement is particularly important because it may determine:

Payment Date → Pricing Formula → Invoice Procedure → Default Interest → Security → Termination → Governing Law → Jurisdiction → Arbitration.

Before commencing proceedings, foreign creditors should therefore review the agreement in full.

Why Electricity Receivables Are Different From Ordinary Commercial Debts

Electricity is continuously supplied and financially calculated over settlement periods.

The amount owed may therefore depend on several interconnected data points.

A typical dispute may involve:

Metered Electricity × Contract Price

plus or minus:

Market Adjustments

YEKDEM Costs

Imbalance Costs

Taxes

Other Contractual Components

This means the debtor may admit receiving electricity but dispute the amount of the invoice.

The creditor should be prepared to prove both delivery and calculation.

What Evidence Should Be Collected?

Before commencing debt recovery, the creditor should create a complete evidence file.

Important documents normally include:

Electricity Sale Agreement

PPA or Bilateral Agreement

Invoices

Metering Records

Settlement Data

EPİAŞ Records Where Relevant

Delivery and Consumption Data

Bank Statements

Account Statements

Payment History

Default Notices

Email Correspondence

Debt Acknowledgments

Reconciliation Records

Security Documents

The stronger the documentary file, the more difficult it becomes for the debtor to create an artificial dispute simply to delay payment.

Is an Invoice Alone Enough?

An invoice is important evidence, but foreign creditors should avoid building a major electricity claim solely around invoices.

If the debtor disputes the underlying relationship or quantity of electricity supplied, additional evidence becomes important.

The creditor should ideally establish:

Contract → Electricity Delivery → Quantity → Price → Invoice → Due Date → Non-Payment.

This creates a clear evidentiary chain.

Metering Records

Meter data can become particularly important when the debtor argues that the invoice includes electricity that was never consumed or delivered.

The creditor should preserve historical meter records before technical data becomes difficult to retrieve.

Where the electricity transaction is connected with organized market operations, corresponding settlement information should also be preserved.

Account Reconciliation

Commercial parties frequently reconcile their accounts.

A signed reconciliation document confirming the amount outstanding can become highly valuable evidence.

For example, if a Turkish debtor confirms that EUR 1.5 million remains outstanding and subsequently refuses payment, the creditor’s evidentiary position may be considerably stronger than where the entire underlying calculation remains disputed.

Electronic correspondence acknowledging the debt may also be relevant.

Payment Default

The first legal question is when the receivable became due.

The agreement should establish the payment deadline.

For example:

Invoice Date: 1 July

Contractual Payment Period: 15 Days

Due Date: 16 July

Once the debt becomes due, default consequences should be analyzed under the contract and applicable Turkish law.

Default Interest

Electricity contracts frequently contain specific default-interest clauses.

The creditor should therefore examine the contract before calculating interest.

Where the contract does not validly determine the applicable interest, statutory rules governing the particular commercial relationship may become relevant.

For substantial electricity receivables, interest can represent a significant part of the final claim.

Foreign Currency Receivables

Energy agreements involving foreign investors may contain EUR or USD pricing components where legally permissible.

Where the receivable is denominated in foreign currency, the creditor should determine how the claim should be pursued and how contractual payment provisions interact with applicable Turkish foreign-currency rules.

The creditor should not automatically convert the receivable into Turkish lira without examining the legal consequences.

Send a Payment Demand Before Enforcement

A formal payment demand can be strategically useful.

The notice can identify:

Contract → Invoice → Outstanding Principal → Interest → Payment Deadline → Consequences of Non-Payment.

The notice may also produce valuable evidence.

A debtor responding:

“We cannot pay this month but will pay EUR 800,000 next month”

may effectively provide evidence relevant to the existence of the debt.

Should Negotiations Continue?

Sometimes.

However, negotiations should not allow the debtor time to dispose of assets.

A foreign creditor should investigate whether the debtor’s problem is temporary liquidity pressure or actual insolvency.

This distinction determines strategy.

A company with strong assets but temporary cash-flow difficulties may justify restructuring.

A company rapidly selling assets may require immediate protective measures.

Enforcement Proceedings in Turkey

Enforcement proceedings can be an important debt-recovery method.

Depending on the nature of the claim, a creditor may be able to commence monetary enforcement without first obtaining a final court judgment.

A payment order is then served on the debtor.

The debtor’s reaction determines the next stage.

If the debtor does not validly challenge the proceedings within the applicable period, enforcement can continue toward attachment and collection.

What If the Debtor Objects?

A debtor may dispute:

Existence of Debt

Amount

Interest

Signature

Jurisdiction

or other elements of the claim.

An objection can stop ordinary enforcement proceedings in the circumstances prescribed by enforcement law.

The creditor must then determine the appropriate procedure for overcoming the objection.

The available route depends on the evidence and nature of the enforcement proceeding.

Commercial Lawsuit

Where the electricity receivable is genuinely disputed, commercial litigation may become necessary.

The creditor can seek judicial determination that the debtor owes the unpaid electricity sale amount.

The case may require examination of:

Contract

Invoices

Meter Data

Settlement Records

Pricing Formula

Payments

Interest

Expert Evidence

Energy-sector expertise can become particularly important where the dispute concerns complicated electricity pricing rather than simple non-payment.

Mandatory Mediation

Foreign companies should remember that many commercial monetary claims in Turkey are subject to mandatory mediation before litigation.

Commercial receivable and compensation claims falling within the statutory framework generally require completion of mediation before filing the lawsuit.

Accordingly, a foreign creditor should determine whether mediation is a procedural prerequisite before commencing court proceedings.

Failure to complete a mandatory pre-litigation step can delay recovery.

Does Mandatory Mediation Prevent Enforcement Proceedings?

The distinction between filing a commercial lawsuit and commencing enforcement proceedings is important.

A creditor should not assume that every available debt-recovery mechanism follows exactly the same procedural route.

The specific claim and intended proceeding should be analyzed before action is taken.

Precautionary Attachment

For foreign energy companies, precautionary attachment can be one of the most important protective remedies.

Consider a foreign generator owed EUR 5 million.

The Turkish debtor owns bank accounts, vehicles and valuable real estate but appears to be transferring assets.

If the creditor spends months negotiating and later files proceedings, the debtor may no longer possess sufficient assets.

Precautionary attachment can potentially secure assets before the creditor obtains a final judgment, provided the statutory requirements are satisfied.

Why Precautionary Attachment Matters

Winning a lawsuit does not guarantee collection.

The commercial objective is not:

Judgment

It is:

Cash Recovery.

Therefore, a debt-recovery strategy should evaluate enforceability from the beginning.

A foreign energy company should ask:

What assets does the debtor own today?

rather than waiting until litigation ends.

What Assets Can Be Investigated?

Depending on the circumstances and applicable enforcement procedures, relevant assets may include:

Bank Accounts

Real Estate

Vehicles

Company Shares

Receivables From Third Parties

Commercial Income

Other Attach­able Assets

A debtor’s balance sheet can also provide useful preliminary information.

Bank Account Attachment

Bank accounts are frequently important targets in commercial enforcement.

Where legally available and properly pursued, funds belonging to the debtor may be attached through enforcement procedures.

However, an account’s existence does not guarantee that sufficient funds will remain when enforcement reaches it.

This is why speed can matter.

Attachment of Debtor’s Receivables

A debtor company may have limited cash in its bank accounts but substantial receivables from customers.

Those third-party receivables can become strategically important.

For example, an electricity trading company may itself be owed significant amounts by industrial customers.

The creditor should therefore investigate not only physical assets but also the debtor’s receivable portfolio.

Real Estate

Real estate can provide substantial recovery value.

If the debtor owns offices, industrial facilities, land or other property, those assets may become relevant to enforcement.

However, the creditor should investigate existing mortgages and prior attachments.

A valuable property with substantial senior security may provide little actual recovery.

Priority Matters

Foreign creditors should not assume they are the only party pursuing the debtor.

The company may owe money to:

banks,

employees,

tax authorities,

suppliers,

bondholders,

and other creditors.

Existing security and attachment priority can therefore materially affect recovery.

An asset worth EUR 10 million does not necessarily secure a EUR 3 million electricity receivable if EUR 9 million of senior claims already exist.

Security Under the Electricity Agreement

The original electricity agreement may contain contractual security.

Possible forms can include:

Bank Guarantee

Letter of Guarantee

Cash Collateral

Parent Company Guarantee

Corporate Guarantee

Security Deposit

Other Contractual Security

The creditor should determine whether security can be called immediately following default.

In some cases, enforcing strong contractual security is significantly faster than pursuing the debtor’s general assets.

Bank Guarantee Disputes

A debtor may attempt to prevent payment under a guarantee.

This can create a separate dispute concerning whether the guarantee is payable, whether the contractual conditions for calling it have been satisfied and whether an injunction is sought.

The guarantee wording should therefore be reviewed before the demand is issued.

Parent Company Guarantee

Foreign energy companies frequently negotiate with project subsidiaries or special-purpose companies.

If the contractual counterparty has limited assets, a parent-company guarantee can be extremely valuable.

The creditor should determine:

Who Issued the Guarantee?

What Obligations Are Covered?

Is There a Maximum Amount?

When Does It Expire?

Which Law Governs It?

Where Must Proceedings Be Brought?

A guarantee that expires while negotiations continue may become worthless.

Can Electricity Supply Be Terminated for Non-Payment?

This depends heavily on the contractual and regulatory structure.

The rules applicable to regulated retail supply should not automatically be applied to bilateral commercial electricity agreements.

In particular, electricity-market guidance distinguishes debts arising under bilateral agreements from regulated supply debts in relation to disconnection mechanisms.

Accordingly, a supplier should review both the contract and applicable electricity-market regulations before using termination or interruption as leverage.

Termination of a Bilateral Agreement

Where contractual conditions are satisfied, persistent non-payment may permit termination.

The agreement should be examined for:

Payment Default

Notice Period

Cure Period

Termination Event

Security Enforcement

Post-Termination Settlement

Surviving Obligations

Termination should be implemented carefully.

Wrongful termination can turn a straightforward receivable claim into a counterclaim for damages.

Debtor Claims the Invoice Is Incorrect

This is common in energy disputes.

The debtor may argue that:

the quantity was wrong,

the pricing formula was misapplied,

YEKDEM costs were incorrectly calculated,

meter data was incorrect,

imbalance costs were wrongly allocated,

or a contractual adjustment was omitted.

The creditor should reconstruct the invoice line by line.

A strong case demonstrates not merely that an invoice exists, but why the exact invoiced amount is correct.

Expert Examination

High-value electricity receivable litigation can require expert analysis.

The calculation may involve thousands of hourly data points.

A technical or financial expert may need to reconstruct:

Meter Data → Contractual Formula → Market Data → Adjustments → Correct Amount.

The more transparent the calculation, the easier it becomes to defend the claim.

Arbitration Clauses

International energy agreements frequently contain arbitration clauses.

If the contract provides for arbitration, the creditor should examine the clause before filing proceedings in Turkish courts.

Important issues include:

Seat of Arbitration

Institution

Number of Arbitrators

Governing Law

Language

Scope of Arbitration Clause

Interim Relief

Starting proceedings in the wrong forum can cause serious delay.

Can Turkish Courts Grant Interim Protection Despite Arbitration?

In international commercial disputes, arbitration does not necessarily eliminate every role for national courts.

Depending on the arbitration structure and applicable law, Turkish courts may potentially become relevant for certain interim protective measures.

This can be particularly important where the debtor’s assets are located in Turkey.

The strategy should therefore coordinate:

Arbitration on the Merits + Asset Protection in Turkey.

Foreign Arbitration Award Against a Turkish Debtor

If the foreign energy company already possesses an arbitral award against the Turkish debtor, the dispute moves into a different stage.

The creditor may need recognition and enforcement procedures in Turkey before executing against Turkish assets, depending on the circumstances.

The award itself does not mean that assets in Turkey will automatically be seized.

Enforcement strategy should therefore begin before the arbitration concludes.

Foreign Court Judgment

Similarly, a foreign court judgment may require recognition and enforcement in Turkey before compulsory enforcement against Turkish assets.

The creditor should determine whether the underlying contract contains a foreign jurisdiction clause and what procedural consequences follow.

Cross-border enforcement should be considered when drafting the original energy contract—not only after default occurs.

Debtor Transfers Assets

Asset transfers immediately before or during debt collection should be investigated carefully.

A debtor may sell property, transfer vehicles, move business operations to another company or divert receivables.

Not every asset transfer is unlawful.

However, transfers intended to prejudice creditors can potentially trigger additional remedies under Turkish enforcement and insolvency law where the statutory requirements are satisfied.

Transactions With Related Companies

Particular attention should be given to transactions involving:

Shareholders

Directors

Affiliated Companies

Family Members

Group Companies

Newly Established Companies

Suppose the debtor energy company transfers its profitable customer contracts to a related entity while leaving unpaid liabilities in the original company.

The creditor should investigate whether additional legal remedies are available.

Insolvent Debtor

The strategy changes substantially when the debtor is genuinely insolvent.

Continuing ordinary debt collection without analyzing insolvency can waste valuable time.

The creditor should determine whether the debtor is subject to:

Restructuring

Concordat Proceedings

Bankruptcy Proceedings

Multiple Enforcement Proceedings

Serious Tax or Social Security Debts

Bank Enforcement

The objective then becomes protecting the creditor’s ranking and maximizing recovery from the available estate.

Concordat Risk

If a debtor seeks concordat protection, individual enforcement actions can be significantly affected.

A foreign energy company should immediately identify:

the amount of its receivable,

whether the debt is disputed,

the security position,

the applicable deadlines,

and how the claim should be registered or asserted.

Missing procedural deadlines can materially damage recovery.

Insolvency Clauses in Energy Contracts

Energy contracts should contain early-warning mechanisms.

The creditor should not have to wait until formal bankruptcy.

Contractual events of default may include:

Failure to Pay

Cross-Default

Insolvency

Concordat Application

Material Deterioration

Loss of License

Failure to Maintain Security

These clauses can allow earlier intervention.

Foreign Creditor Does Not Need to Wait

A foreign company should not assume that being incorporated outside Turkey prevents it from using Turkish debt-recovery procedures.

Foreign creditors can pursue claims against Turkish debtors, subject to applicable procedural requirements.

Cross-border documentation, powers of attorney, translations and potential security-for-cost issues should nevertheless be assessed at the beginning.

Currency Risk During Litigation

Long-running litigation can create serious currency exposure.

A EUR-denominated receivable may have a very different economic value depending on how the claim, interest and payment obligations are legally structured.

Foreign creditors should therefore consider currency issues when selecting the claim formulation and settlement strategy.

Settlement Negotiations

Commercial settlement can sometimes produce better recovery than lengthy litigation.

However, any restructuring agreement should strengthen—not weaken—the creditor’s position.

A creditor accepting installment payments can request additional security such as:

Bank Guarantee

Parent Guarantee

Acknowledgment of Debt

Additional Collateral

Acceleration Clause

A simple promise to pay later may merely give the debtor additional time to dispose of assets.

Debt Acknowledgment

Obtaining written acknowledgment of the outstanding amount can be particularly valuable.

The document should clearly identify the parties, underlying transaction, principal debt, payment schedule and consequences of default.

Where appropriate, stronger enforceability structures should be considered.

Acquiring an Energy Company With Unpaid Receivables

Foreign investors buying a Turkish generation or supply company should independently analyze its receivable book.

A balance sheet may show TRY 500 million of trade receivables.

That does not mean TRY 500 million will actually be collected.

Due diligence should classify receivables by:

Age

Debtor

Security

Dispute Status

Enforcement Status

Probability of Recovery

Existing Provision

Old electricity receivables can conceal substantial acquisition risk.

Seller Claims Receivables Are Fully Recoverable

The buyer should not accept this statement without evidence.

A receivable outstanding for two years against an insolvent customer should not necessarily be valued at face value.

The buyer should examine payment history and debtor assets.

A purchase-price adjustment may be appropriate where collection is doubtful.

SPA Protection for Electricity Receivables

An acquisition agreement can allocate collection risk through:

Working Capital Adjustment

Specific Warranty

Indemnity

Receivable Retention

Deferred Consideration

Seller Collection Guarantee

The structure depends on whether the receivable economically belongs to the buyer or seller after closing.

Example: Foreign Generator Owed EUR 4 Million

A foreign-owned renewable generator sells electricity under a bilateral agreement.

The Turkish buyer stops paying and accumulates EUR 4 million of debt.

The debtor nevertheless owns substantial real estate and maintains active commercial operations.

The creditor should simultaneously assess:

Evidence of Debt → Contractual Security → Enforcement → Precautionary Attachment → Debtor Assets → Mandatory Mediation/Litigation if Required.

Waiting for voluntary payment may significantly increase collection risk.

Example: Debtor Objects to the Payment Order

A foreign energy trader commences enforcement proceedings.

The Turkish debtor objects and alleges that the pricing formula was incorrectly applied.

The creditor should reconstruct the contractual calculation using settlement and market data and pursue the appropriate procedure to overcome the objection.

The dispute has now moved from simple collection to a substantive commercial claim.

Example: Debtor Starts Selling Assets

A Turkish electricity buyer stops paying several suppliers and begins transferring assets.

The foreign creditor should not focus solely on sending additional payment reminders.

Immediate investigation of precautionary attachment and other creditor-protection remedies may be necessary.

Example: Corporate PPA Payment Default

An industrial company purchases renewable electricity under a long-term corporate PPA but begins missing monthly payments.

The generator should review security, cure periods, termination rights, acceleration provisions and dispute-resolution clauses.

If the buyer’s financial condition is deteriorating, securing the existing debt may be more important than preserving future electricity sales.

2026 Debt Recovery Strategy

For foreign energy companies, an efficient collection strategy generally follows:

Verify Debt → Preserve Evidence → Review Contract → Calculate Interest → Investigate Security → Investigate Debtor Assets → Send Formal Demand → Consider Precautionary Attachment → Commence Enforcement → Complete Mandatory Mediation Where Required → File Commercial Proceedings or Arbitration → Enforce Against Assets.

The sequence may change where there is an immediate risk of asset dissipation.

In such cases, asset protection can become the first priority.

Major Red Flags

Foreign energy companies should act particularly quickly where the debtor repeatedly requests payment extensions, stops responding, disputes previously accepted invoices, refuses account reconciliation, transfers assets to related companies, changes its registered office, loses major customers, faces multiple enforcement proceedings, seeks concordat protection or begins selling valuable assets.

These developments can indicate that an ordinary commercial payment delay is becoming a serious collection problem.

Frequently Asked Questions

1. Can a foreign energy company recover unpaid electricity invoices in Turkey?

Yes. Foreign companies can pursue Turkish debtors through the applicable enforcement, litigation or arbitration mechanisms, subject to procedural requirements.

2. Is a court judgment always required before enforcement proceedings?

Not necessarily. Depending on the receivable and enforcement route, monetary enforcement may be commenced without first obtaining a judgment.

3. What happens if the Turkish debtor objects?

The creditor may need to pursue the appropriate procedure to overcome the objection and establish the receivable.

4. Is mediation required before filing an electricity receivable lawsuit?

Commercial monetary claims can fall within mandatory pre-litigation mediation requirements. The specific claim should be assessed before filing proceedings.

5. Can the debtor’s bank accounts be attached?

Potentially, subject to the applicable enforcement requirements and availability of attachable funds.

6. Can a foreign creditor obtain precautionary attachment?

Potentially yes, where the statutory conditions are satisfied. This can be especially important where there is a risk that assets will disappear before judgment.

7. Can default interest be claimed?

Generally, interest may be recoverable depending on the contractual terms and applicable legal rules.

8. What if the electricity sale agreement contains arbitration?

The arbitration clause should be reviewed before proceedings are commenced. Arbitration may govern the merits while separate interim asset-protection issues may need to be considered.

9. What if the Turkish debtor is insolvent?

The creditor should immediately assess concordat, bankruptcy, security and priority issues rather than relying solely on ordinary collection methods.

10. What is the biggest mistake foreign creditors make?

Waiting too long. A strong legal claim has limited commercial value if the debtor no longer owns assets when enforcement finally begins.

Legal Support for Unpaid Electricity Receivables in Turkey

Electricity debt recovery should combine energy-market knowledge with commercial litigation and enforcement strategy. Establishing that electricity was sold is only the first step. The creditor must also prove the amount, protect its procedural position and identify assets from which the debt can actually be recovered.
