Infrastructure Concessions in Singapore
Infrastructure concessions in Singapore let private companies design, build, finance or operate water, waste, energy, transport and public facilities under long-term contracts. There is no single concessions statute: each deal combines government procurement rules, sector licensing and a detailed contract. This guide explains the models, the key terms and the lessons Singapore's own PPPs teach bidders and lenders.
Key pointSingapore's agencies put service continuity first and have used their step-in and takeover rights in practice, so bids and financing should be built around the termination, step-in and compensation provisions, not treat them as boilerplate.
At a glance
No concessions statute
Concessions combine MOF procurement policy, the Government Procurement Act 1997 where it applies, sector licensing law and a long-term contract that allocates risk.
Several PPP models
Singapore has used DBOO offtake contracts for water and waste-to-energy, availability-based DBFO contracts for public facilities, and licensed operator models for transport.
Takeovers do happen
PUB took over the Tuaspring desalination plant in 2019 after Hyflux's financial difficulties, and Sport Singapore took over the Sports Hub in 2022.
Sector licences still apply
Contracts cannot override sector statutes; power assets, for example, need licences from EMA under the Electricity Act 2001 alongside the concession.
Energy processes continue
EMA's April 2026 request for proposal for hydrogen-ready generation capacity and its import licensing show competitive energy infrastructure processes remain active.

What infrastructure concessions in Singapore cover
Infrastructure concessions in Singapore are long-term arrangements under which a private company designs, builds, finances, operates or maintains an asset or service that the public relies on, in return for payments from a public agency, payments from users, or the right to sell output. They include public-private partnerships (PPPs) for desalination, water reclamation and waste-to-energy plants, availability-based contracts for public facilities, operating licences for rail and other transport, and competitive processes for new power generation capacity.
Singapore has no single concessions statute. Each arrangement is built from three things: the procurement rules that govern how the government chooses its partner, the sector law that licenses or regulates the activity, and a long-term contract that allocates risk for decades. Understanding how those three interact is the core of the legal work.
The model is selective. Singapore's government has strong finances and has used PPPs where private-sector innovation, operating expertise or risk transfer offer real value, rather than as a way of moving debt off the public balance sheet. That shapes how agencies negotiate: they expect a demonstrable value-for-money case and keep firm control over service continuity.
The legal and regulatory framework
Procurement rules for infrastructure concessions in Singapore
Concessions awarded by government agencies are procurements. They follow the Ministry of Finance's policies, published on its procurement processes page, which require tenders for high-value contracts and evaluation on value for money rather than price alone. Where a procurement falls within the Government Procurement Act 1997 and the Government Procurement Regulations 2014, bidders from countries with procurement commitments have additional rights, including the right to challenge breaches before the Government Procurement Adjudication Tribunal. Our government procurement page explains those rules.
Sector regulation
The asset's sector law runs alongside the contract. Power generation and import are licensed under the Electricity Act 2001 by the Energy Market Authority (EMA). Water assets sit within PUB's statutory framework, waste-to-energy within NEA's, and public transport within the Land Transport Authority's licensing regime for rail and bus services. Changi Airport is operated by Changi Airport Group as the airport licensee under the oversight of the Civil Aviation Authority of Singapore, which has announced major investment plans for the airport.
A concession contract cannot override these statutes. If the concession company needs a licence, it must obtain and keep it, and the regulator retains its enforcement powers independently of the procuring agency. Bidders should map every licence, permit and approval the project needs over its life, not just at construction.
Land, planning and environmental approvals
Most concession sites are state land made available by the procuring agency or another public landowner, typically under a lease or licence whose term is tied to the concession. The land document should end, transfer or survive in step with the concession contract, or the operator may hold a contract without the site to perform it. Planning permission from the Urban Redevelopment Authority, building plan and structural approvals from the Building and Construction Authority, fire safety approval from the Singapore Civil Defence Force and environmental controls administered by NEA all apply during construction and, in many cases, through operation.
For larger projects, agencies may require environmental studies and community or traffic management plans before works begin. Some of this work is done by the agency before tender, and some is passed to the bidder. The tender documents should say which, and the concession contract should allocate the risk of a study revealing conditions that change the design or cost.
Evaluation of concession bids usually goes well beyond price. Agencies look at technical solution, operating track record, financial strength, the robustness of the financing plan and the degree to which the bid accepts the proposed risk allocation. A bid that heavily marks up the contract may lose points or be treated as non-compliant, so bidders must choose carefully which issues to raise and when.
Concession and PPP models compared
Singapore has used several models. The choice decides who takes demand risk, how the private partner is paid and what happens at the end of the term.
| Model | How the private partner is paid | Typical assets | Main risk transferred |
|---|---|---|---|
| Design-build-own-operate (DBOO) with offtake | Long-term purchase of output by the agency, such as water or waste treatment capacity | Desalination, water reclamation, waste-to-energy | Construction, operation, availability and performance |
| Design-build-finance-operate (DBFO), availability-based | Periodic availability payments, reduced for unavailability or poor performance | Public facilities such as sports or education campuses | Construction, lifecycle maintenance and service performance |
| Licensed operator of government-owned assets | Fees or fares under a licence or service contract; government owns key assets | Rail operations, bus service packages | Operating performance, with asset investment kept by government |
| Licensed merchant or contracted generation | Market revenue or contracted payments under an EMA process | New power generation capacity, electricity imports | Construction, fuel, market and regulatory risk |
| Airport and port licensing | Charges to users under a regulated licence | Airport, port terminals | Demand, operations and investment, under regulatory oversight |
Transport shows how models change over time. Rail moved to a framework in which the government owns the operating assets and operators run services under licence, and bus services moved to a contracting model in which the LTA tenders route packages and owns the buses. In both cases, the government took back asset ownership to improve reliability and allow competition between operators.
Lessons from Singapore's PPP experience
Two well-known projects show why termination and step-in clauses matter. In 2019, PUB took over the Tuaspring desalination plant after its private owner, Hyflux, ran into serious financial difficulty, and water supply continued without interruption. In 2022, the Singapore Sports Hub PPP ended early and Sport Singapore took over the venue's management and operations.
Neither event was a failure of the asset. Both show that the contract's provisions on default, step-in, termination compensation and transfer of staff and records will be used. Sponsors and lenders should assume that the government can and will rely on its rights to protect service continuity, and price their bids and financing accordingly.
The lessons cut both ways. For sponsors, they show that parent company weakness, not just project performance, can trigger the agency's rights, so sponsor support arrangements and cross-default clauses deserve close attention. For lenders, they confirm the value of direct agreements that give a real window to step in and find a replacement operator before the agency terminates. For agencies, they show that clear transfer provisions for staff, spare parts, software and records make takeovers smoother. A careful reading of these clauses at bid stage is far cheaper than discovering their effect during a crisis.
In Singapore, service continuity comes first. Concession contracts are drafted on the assumption that the government will step in if it must, so the real negotiation is about how, when and at what compensation.
Key contract terms
Infrastructure concessions in Singapore are documented in long, detailed contracts. The following provisions do most of the work.
Payment mechanism
Availability or capacity payments, output tariffs and indexation. Deductions for unavailability and poor performance must be measurable and proportionate, or they become the main source of disputes.
Relief and compensation events
Which events, such as change in law, agency delay or force majeure, give the operator more time, money or both. The list and the procedure for claims matter as much as the principle.
Step-in rights
When the agency or lenders may take over operations, for how long, and who bears the cost. Lender step-in usually comes first through a direct agreement.
Termination compensation
Amounts payable on operator default, agency default, voluntary termination and force majeure. Lenders focus on the debt they will recover in each case.
Handback
The condition in which assets must be returned at the end of the term, inspection regimes, retention or bonding to secure handback, and transfer of records and staff.
Change of control and refinancing
Restrictions on selling shares in the concession company, and sharing of any refinancing gains with the agency.
These provisions must line up with the construction contract, the operation and maintenance contract and the financing documents. A gap between what the operator owes the agency and what its contractors owe the operator stays with the concession company, which usually has few assets other than the project. Our construction contracts and banking and finance teams review the full contract chain together.
Insurance and interfaces deserve equal attention. Concession contracts usually specify the insurances the operator must carry during construction and operation, and what happens if cover becomes unavailable or unaffordable on the market. Where the asset connects to public networks, such as the power grid, water mains or transport systems, interface agreements with the network owner set technical standards, access and liability. Delays at an interface are a common cause of late commissioning, and the concession contract should say whether they count as relief events.
Bidders should also check how the agency's own obligations, such as providing the site, connections or input materials on time, are defined and what remedies the operator has if the agency is late.
Bid process and timeline
- Market sounding. Agencies may consult the market before tendering. Responding helps shape risk allocation, but treat anything submitted as potentially shared and keep confidential material clearly marked.
- Consortium formation. Agree roles, exclusivity, cost-sharing and decision-making in a consortium or teaming agreement, and check competition law limits on cooperation between competitors.
- Pre-qualification. Many large concessions use a selective process. Submit evidence of technical capability, financial strength and relevant experience.
- Bid preparation. Develop the technical solution, financial model and legal mark-up within the limits the tender allows. Obtain lender support letters and contractor commitments.
- Clarification and negotiation. Raise risk allocation issues through the formal process. Where negotiation is allowed, focus on the provisions that affect financing.
- Award and financial close. Sign the concession contract, construction and operating contracts, financing documents and direct agreements. Satisfy conditions precedent, including licences.
- Construction, operation and handback. Manage the contract for its full life, including performance reporting, relief claims, lifecycle works and the handback process.
Documents to assemble
A bid needs constitutional and financial documents for each consortium member, evidence of experience, the consortium agreement, the technical proposal, the financial model with audit, the legal mark-up, lender support letters, key subcontractor term sheets, insurance proposals and a map of required approvals. After award, add the full suite of project documents, licences, direct agreements, security documents and legal opinions for financial close.
During the operating phase, keep monthly performance reports, deduction calculations, relief and compensation claims with supporting evidence, lifecycle plans, insurance renewals, licence compliance records and correspondence with the agency. Infrastructure concessions in Singapore can run for decades, and the people who negotiated the contract will move on. A well-organised record of interpretations, agreed variations and waivers protects the concession company when questions arise years later.
Do not treat sector approvals as someone else's problem. Show the agency a credible plan for every licence and permit the asset will need over its life, and make sure the concession contract says what happens if an approval is delayed or refused despite proper efforts.
Risks and common mistakes in infrastructure concessions in Singapore
Under-pricing lifecycle and handback costs
Bidders often focus on construction cost and early operations and underestimate the cost of replacing equipment over a 20 or 25-year term and returning the asset in the required condition. Agencies may require retention, bonding or a handback inspection regime to protect themselves. Model lifecycle replacement carefully, align the operation and maintenance contract with the handback specification, and check whether the concession allows reserve accounts to be funded from revenue. Under-funded lifecycle reserves are a common cause of distress late in a concession.
Mismatched back-to-back contracts
If the construction contract's liquidated damages, defects period or performance guarantees do not match the concession company's obligations to the agency, the concession company carries the gap. The same applies to the operation and maintenance contract and performance deductions. Map each obligation and liability through the chain, and check caps, time bars and dispute resolution clauses for consistency. Consider a joined dispute mechanism so that related claims can be heard together.
Relying on general force majeure and frustration
Long-term contracts face events that no one predicted at signing, such as pandemics, sharp cost inflation or new regulation. Courts apply frustration narrowly, so the contract must provide the relief. Negotiate clear relief, compensation and change-in-law provisions, with a process for adjusting payments where costs change materially. Our post on concession strategy explains how bidders can plan for approval and change-in-law risk.
Weak consortium governance
Consortium members often sign a short teaming agreement for the bid and leave the long-term shareholder arrangements until after award. Disagreements about funding, management, transfers and exit then arise when the project is under pressure. Agree the main shareholder terms before bidding, including funding obligations, deadlock, transfer restrictions that match the concession's change-of-control rules, and what happens if a member defaults. Our joint ventures team prepares these agreements.
Ignoring the operating phase in the dispute clause
Disputes during construction are often about time and cost. Disputes during operation are about performance deductions, relief events and lifecycle obligations, and need fast technical resolution. A good dispute clause provides for escalation, expert determination for technical issues and arbitration or court for the rest. Singapore-seated arbitration under the SIAC Rules 2025 is common in contracts with private parties, while agency contracts may require Singapore courts.
The cross-border angle
Many sponsors and lenders for infrastructure concessions in Singapore come from overseas, and Singapore companies also use their experience to bid for concessions elsewhere in Asia and the Middle East. Low-carbon electricity imports, approved through EMA's staged process on its regional power grids page, combine a Singapore licence with generation and transmission concessions in neighbouring states. EMA's April 2026 request for proposal for new hydrogen-ready generation capacity shows that competitive processes for energy infrastructure continue at home too.
TRW & Co's network supports sponsors from several directions. Gulf investors and operators, including those based in the UAE, bring experience of large utility concessions and often prefer Singapore-seated arbitration.
Chinese contractors and equipment suppliers are active in regional infrastructure. UK and Swiss lenders and investors bring PPP practice from their home markets, which helps but does not always fit Singapore's approach. Bangladesh has its own PPP programme, and Singapore is a natural base for structuring and financing regional projects. We coordinate Singapore-law advice with local counsel in each jurisdiction. Our international arbitration team advises on dispute clauses across these chains. Where Singapore court or tribunal representation is required, we work alongside Singapore-qualified counsel.

Checklist for decision-makers
- Do we understand which procurement rules apply, including whether the Government Procurement Act covers this concession?
- Have we mapped every licence and approval the asset needs over its full life?
- Is the payment mechanism measurable, and have we modelled deductions realistically?
- Are relief, compensation and change-in-law events clearly defined, with workable claim procedures?
- Do construction, operation and financing documents match our obligations under the concession?
- Have we priced lifecycle replacement and handback, and agreed how reserves are funded?
- Are consortium funding, governance and exit terms agreed before bidding?
- Does the dispute clause work for both construction and operating disputes?
Sponsors who can answer yes to each question are well placed to bid for, finance and run infrastructure concessions in Singapore over their full term.
Frequently asked questions
01Does Singapore have a PPP law?
No. There is no dedicated PPP or concessions statute. Concessions are government procurements governed by Ministry of Finance policies and, where applicable, the Government Procurement Act 1997 and its Regulations. Sector statutes, such as the Electricity Act 2001 for power, govern the activity itself. The concession contract sets out the commercial terms, so its detailed drafting carries far more weight than in jurisdictions with a PPP code.
02Can a foreign company bid for a Singapore concession?
Usually, yes, subject to the eligibility criteria in the tender. Many concessions are won by consortia including foreign sponsors, contractors and operators. In practice, bidders typically set up a Singapore special purpose company for the project, both to meet tender requirements and to hold licences and financing. Suppliers from countries with procurement commitments to Singapore have extra protection in covered procurements.
03What happens if the concession company fails financially?
The concession contract and lender direct agreement decide this. Lenders usually have the first right to step in and cure defaults or transfer the project to a new operator. If that fails, the agency can terminate and take over the asset, paying compensation calculated under the contract, which may be limited on operator default. Singapore's experience with Tuaspring shows that agencies will act to protect service continuity.
04How are performance deductions usually calculated?
Availability-based and offtake contracts reduce payments when the asset is unavailable or fails to meet performance standards. The contract defines what counts as unavailability, how it is measured, grace periods for rectification and the deduction for each failure. Bidders should test these definitions against realistic operating scenarios, because aggressive deductions can erode the margin that services the debt.
05Who bears the risk of a change in law?
That depends on the contract. Typically the operator bears general changes in law that affect all businesses, while the agency compensates for discriminatory or project-specific changes, and sometimes for changes requiring capital expenditure above a threshold. Read the definitions carefully and raise allocation issues during clarification, because lenders will focus on this risk.
06Can a concession company be sold during the term?
Usually only with the agency's consent, at least for a lock-in period after construction, because the agency chose the sponsors for their capability. The contract may allow transfers to qualified buyers after that period. Refinancing usually requires consent too, and the agency may be entitled to share any gain. Check these limits before agreeing exit rights in the shareholders' agreement.
07What dispute resolution is typical?
Many concession contracts include escalation to senior representatives, expert determination for technical matters and arbitration or Singapore court proceedings for other disputes. Agency contracts may specify Singapore courts, while contracts between private parties in the chain often use Singapore-seated arbitration. Make sure the clauses in each contract allow related disputes to be resolved consistently.
