For contractors, component suppliers and developers in wind, solar and storage projects, debt recovery for renewables turns on the paperwork behind an invoice, not the turbine or panel it paid for. A counterparty who accepted delivery and then stopped paying is common once a project moves past construction. We assess the claim and the debtor's position abroad before taking the file on.
Unpaid balances in this sector rarely start as a single missed payment. A developer accepts delivery of turbines, inverters or cabling, commissions the asset, and then withholds a milestone payment while a dispute over performance or timing runs in the background. Component suppliers exporting equipment across borders face the same collection pattern as debt recovery for exporters in other sectors, with one addition: the buyer is often a special purpose vehicle set up only to hold the project.
Retention money held back pending commissioning is a frequent flashpoint, as are disputes over currency conversion when contracts are priced in one currency and paid in another. Operation and maintenance providers see the same pattern once a project owner changes hands or a financing round falls through. In each case the debtor's stated reason for non-payment matters less than what the contract and the delivery record actually show.
The file that wins is built before the dispute starts. A signed purchase order or EPC contract with clear payment milestones, a delivery or commissioning certificate, and any variation order altering scope or price form the core of the claim. Correspondence in which the debtor acknowledges the balance, even informally, often carries more weight than the original contract itself.
The corporate structure behind the buyer deserves separate attention. A special purpose vehicle with no assets of its own is a different opponent from a parent company that stands behind it. The distinction decides whether the claim is worth pursuing at all. This step overlaps with what a business already knows from international debt collection work in other sectors, and it is where an assessment either opens or closes the file.
The most common defence is a claimed shortfall in performance, tied to output figures the buyer disputes or a permitting delay it blames on the supplier. A second is an attempt to set off the unpaid invoice against a retention sum or a separate claim under the same contract. A third, seen mainly with project-company buyers, is that the debtor entity itself holds no assets against which any claim could be enforced.
A documented commissioning sign-off with no timely notice of defect usually defeats the performance argument, since most contracts fix a window for raising quality complaints. Set-off claims fail where the contract separates the payment obligation from the dispute the debtor is trying to attach to it. Where the debtor is a shell, the question moves to whether a parent undertaking exists, a point that also arises in cross-border litigation against project vehicles generally.
A formal demand referencing the delivery record and the contract terms is the starting point, followed by a short negotiation window before any procedural step is taken. Where the debtor's assets are unclear, we commission an asset report on the debtor before committing to litigation or arbitration, since the report often changes what the claim is worth pursuing for.
If the contract carries an arbitration clause, that route generally takes priority over litigation in the debtor's home court. Where no such clause exists, or where the debtor's assets sit outside the forum named in the contract, the practical question becomes where a judgment or award can actually be enforced, not only where it can be obtained.
It covers unpaid invoices, withheld retention and disputed milestone payments arising from the supply, construction or operation of a wind, solar or storage project. The counterparty is typically a developer, an EPC contractor, a project company or an operations and maintenance provider. The dispute usually follows delivery or commissioning, once an underlying performance issue becomes a payment issue.
Recovery depends on the contract's dispute clause, the debtor's corporate structure and where its assets sit, not on the size of the project. A claim against a contractor with real assets in an accessible jurisdiction is a different proposition from a claim against a project vehicle with none. We assess the debtor's position before recommending litigation, arbitration or a negotiated settlement.
The timeline depends on the dispute route the contract sets out, whether the debtor contests the claim, and where enforcement ultimately has to happen. A claim against a solvent, cooperative counterparty resolves faster than one against a shell company with assets spread across several countries. We give a realistic view of the timeline once the file has been assessed, not before.
Renewables projects move quickly once financing closes, and the debtor's cash often moves with them, into the next project or back to a parent company that owes nothing directly. A supplier who waits to see whether the balance is paid voluntarily is usually the last creditor to act, not the first. The position only gets harder to assess once the special purpose vehicle behind the contract has been wound down or refinanced.
