Infrastructure PPP

Infrastructure PPP in India Legal Framework, Contracts, Risks and Disputes

Why Infrastructure PPP Matters in India in 2026

Infrastructure projects can require huge capital investments, technical expertise and long-term management. PPPs allow the public and private sectors to pool these resources, within the contractual and regulatory parameters of the project.

The existing PPP framework of Government of India continues to provide project appraisal guidelines, Viability Gap Funding, project development support and model contractual guidance. PPPAC framework will still be applicable for appraisal of eligible Central Sector PPP projects.

As per recent records PPPAC were even issued in 2026 for continuing projects such as Hybrid Annuity Model for major road and expressway projects.

This means that for private entities there will continue to be significant infrastructure investment opportunities within the PPP structure.

But a PPP contract is not just procurement followed by a construction phase.

It is a complex arrangement that may span years or decades. The legal agreements must be flexible enough to withstand fluctuations in government policy, economic conditions, demand for the project’s services, financing costs, changes in technology and even unforeseen events such as regulatory intervention.

While a road project may seem like an engineering venture, legally it can encompass land availability, right of way, tolling rights, environmental clearances, shifting of utilities, project financing, change in law, termination payments and even arbitration.

An urban infrastructure PPP can raise issues around municipal powers, service standards, performance deductions and user fees.

Quick Facts

• There is no single Central PPP law. PPP projects are usually subjected to project/transaction specific and sector specific contract and regulatory regime.
• The concession agreement typically forms the key legal instrument which sets out allocation of responsibilities and risk.
• PPP models used by Government include BOT, HAM, TOT and DBFOT among others depending on the sector and project.
• PPP projects under central sector may be appraised by Public Private Partnership Appraisal Committee, if applicable.
• Viability Gap Funding support can be provided to eligible PPP projects for infrastructure as per the relevant government scheme.
• Major infrastructure contracts usually contain arbitration clauses.
• Land, approvals, change in law, force majeure, revenue, termination etc. are some of the most commercially sensitive PPP risks.

What Is an Infrastructure PPP?

An Infrastructure PPP is a form of agreement where a public authority and a private sector party each undertake development/delivery responsibility for an infrastructure asset/service.

Financing, design, construction, operation, maintenance or some combination thereof may be performed by the private sector party.

Ownership can be structured in different ways.

Monetary flows can be structured in different ways.

In some projects, the private sector party bills users/tolls. In other projects, the private sector is paid by the government through annuity or availability payments. Some projects utilize both user tolls and government payments.

A PPP Contract should specify:

• Who does what?
• When should it be done?
• At what cost?
• And what are the consequences if it isn’t done?

These four questions seem straightforward. Many big PPP disputes occur because the contract provides incomplete answers to these questions.

Corporate Law Firm can assess the transaction for contractual risk instead of reviewing it for document format.

What Is a Concession Agreement?

The concession agreement will often be the main contract between the public authority and the concessionaire in a PPP.

Outlining the legal and commercial terms of the project.

Although recently published government PPP guidance in 20 26 continues to highlight concession agreements as one of several legally binding agreements which may be used to structure PPPs.

A properly constructed agreement will deal explicitly with issues such as project scope, period of concession, construction requirements, performance standards, payment mechanisms, consents, defaults, termination and dispute resolution.

Small ambiguity in drafting can lead to significant commercial consequences.

Take for example a provision that obliges the authority to transfer title to a certain percentage of the project site by a certain date.

If the agreement does not specifically address the consequences of a partial handover, a major dispute could erupt if the concessionaire is unable to proceed with construction on time.

The consequences of delay are quite substantial.

There can be financing costs, EPC claims for time and loss of project profits.

BK Singh Advocate will examine concession agreements from that practical point of view.

How Does the Bidding Process Affect PPP Rights?

PPP disputes can arise before contracts have even been signed.

Conditions of tender are important.

RFQ documents may define eligibility.

RFP documents may set out technical and financial bid requirements.

Bid security, performance security, net-worth stipulations, consortium agreements and technical requirements should all be reviewed.

Just because a bidder has received an explanation during pre-bid meetings does not mean the tender has been changed. Ensure that all clarifications are confirmed in writing through the proper channels.

The same goes for assumptions used during financial models. Always confirm with the actual concession document.

Corporate can review conditions of tender prior to submission so commercial teams know where key legal risks are.

How Do Approvals and Permits Affect PPP Projects?

Infrastructure projects may need several approvals.

Environment approvals, building permits, utility permits, sector licences and municipal clearances are just some that may come into play.

The concession agreement should allocate which party will apply for which approval.

Generally, if the concessionaire has control over the approval process, it should normally bear the routine risk of delay due to an incomplete application.

However, to the extent that an approval is subject to a governmental action by another authority, the risk should be allocated differently.

The developer should not assume that any approval will be handled by the government contracting authority merely because it is a government entity.

One government agency may not control the actions of other government agencies.

BK Singh Advocate can assist you in identifying these issues at the document-review stage.

What Happens When Project Costs Increase?

Cost escalation can be due to materials, financing, design development, delay, labour rates or change in regulations.

Can the concessionaire recover those increases depends mainly on the contract and governing law.

Fixed-price allocation may leave run-of-government inflation risk with the private entity.

Change in scope directed by the granting authority may initiate another mechanism.

Change in law may allow its own compensation formula.

Delay caused by another party to the contract can allow for separate claims under the contract.

Do not use one descriptor for all cost increases.

This issue becomes important when trying to resolve disputes.

How Does Change in Law Work?

Long concession periods open up the possibility that legal or regulatory requirements change after contract execution.

This could occur with respect to taxation, sector regulation, environmental obligations or other applicable laws.

Change-in-law clauses can stipulate qualifying events and determine available relief.

The language is key.

Some clauses only apply if there is material financial impact to the private party.

Some clauses provide thresholds or exclude certain foreseeable changes from relief.

Notice provisions may be strict.

If a developer determines that something has a financial impact but misses issuing contractual notice within the specified time period, it could easily create a dispute that would have otherwise been avoided.

Corporate Law Firm can help review change-in-law clauses, notice requirements and compensation provisions.

What Is Force Majeure in an Infrastructure PPP?

Force majeure clauses only deal with listed events outside of the parties’ usual control.

Construction contracts often make finer distinctions within “acts of God and the like.”

Acts of Nature might be carved out from political acts or acts of authorities.

Relief can differ as well.

The occurrence of one event may only entitle a party to an extension of time.

The occurrence of another event may allow recovery of costs.

The continuation of a force majeure event may eventually give rise to a termination right.

Consult your force majeure clause before assuming any unforeseen event automatically gives you relief.

Are you able to point to actual impact on the project.

Why Are Project Notices Important?

Large contracts are notice driven.

Even if you have a valid claim you may still lose out if you fail to give notice of that event within a contractual time limit.

Claims can be for delay, variation, force majeure, compensation events, default etc. as well as notice of dispute escalation.

Project teams tend to regard notices as mere project administration.

Get the site team talking to the lawyers at the outset.

Don’t leave it until the start of arbitration to try and piece together three years worth of project correspondence.

How Is Project Financing Protected?

PPP projects are often heavily debt financed. For that reason lenders carefully review project contracts. The financing documents may include security documents, escrow arrangements, substitution rights and direct agreements with counterparties. Lenders want to be sure that the project can operate or their rights can be enforced if the concessionaire defaults.

It is critical that the concession agreement and financing package work together. Conflicting documents create difficulties. For example, if the financing assumptions require cash-flow rights that the concession agreement prohibits the project may not be able to achieve financial close. Corporate Law Firm can help you review your contracts for consistency.

What Happens If the Authority Delays Its Obligations?

Of course parties to government contracts can also breach.

Late site handover, failure to provide access as agreed, late approvals where the contractor has responsibility or non-payment of amounts under the contract are examples.

The remedy available to the private party will depend on the agreement.

Remedies can include extension of time, financial compensation, suspension rights and ultimately termination for serious breaches.

Whereever possible a developer should prove the causal link.

If delaying access to land caused the EPC contractor to demobilise then prove it. General statements have little weight when compared to contemporaneous project records.

What Happens If the Concessionaire Defaults?

Private parties can also default.

Non-performance on construction deadlines, performance security or required levels of service or failure to perform other material provisions of the contract may allow for default. Privately financed agreements typically include a cure period prior to termination for specified defaults.

Some defaults are black and white.

Others depend on interpretation.

Can PPP Disputes Go to Arbitration?

Yes,indeed. Arbitration is common in infrastructure & concession agreements.

The Arbitration and Conciliation Act, 1996 contains India's primary legislation on arbitration.

PPP agreements sometimes lay down negotiation/conciliation or dispute boards prior to arbitration.

Aggrieved parties are usually required to follow the escalation mechanism agreed to by the parties.

There can also be issues concerning constitution of the tribunal, seat of arbitration,interim measures and setting aside of awards.

If not carefully drafted, the arbitration clause itself can become the subject of a preliminary dispute.

You may want BK Singh Advocate to review your dispute- resolution clauses prior to a dispute arising. It is always cheaper to spend on that than argue later about the meaning of the clause.

Can Courts Intervene in Infrastructure Disputes?

Whether Courts have to be involved would depend on the nature of the dispute and the statutory regime involved.

Disputes relating to arbitration may involve applications for interim relief, appointments related issues or challenges to award or enforcement of awards.

Disputes relating to contracts also end up in Commercial Courts where the issues in dispute are not covered by arbitration.

Disputes involving challenges to public law may involve an entirely different set of issues where decision making involves Government.

A disappointed bidder objecting to the decision to accept a tender is in a completely different position to a concessionaire seeking contractual damages after the project has been awarded.

Corporate Law Firm considers this aspect before advising clients on litigation.

What Documents Should Be Reviewed in a PPP Project?

PPP files are usually voluminous.

Legal due diligence should include (among other things):

• Request for Qualification proposals;
• Request for Proposal / bids specifications;
• concession contract;
• schedules / technical specifications;
• performance guarantee;
• EPC agreement / O&M Agreement;
• financing agreements;
• escrow agreements;
• lender / direct agreement;
• land -transfer documents;
• permit / approvals;
• environmental reports;
• progress reports;
• change-order agreements;
• emails and contract notices;
• payment guaranties;
• engineer or authority decision;
• force majeure documents;
• insurance policies;
• termination / default notices.

Documents must be read in conjunction.

The concession may be subject to a schedule.

The schedule may refer to the RFP.

Financing documents may obligate the parties in addition to the concession.

Reading documents in isolation leads to mistakes.

When Should a PPP Developer Consult a Lawyer?

There should be legal review before execution as well as after a dispute arises.

Deal with a lawyer when the bid documents giveundefined risk, land titles are undefined, financial conditions don’t mesh with concession documents, demands for performance security are significant or uncommon project termination provisions exist.

Legal advice is valuable later in the process when:

• the government fails to provide land or approvals in a timely manner;
• project milestones are at risk;
• a compensation event occurs;
• change-of-law costs are being incurred;
• you receive substantial claims from your EPC contractor;
• performance deductions are made;
• formal default notices are issued;
• termination is being negotiated; or
• arbitration is on the horizon.

The earlier you seek advice, the more options you will have. Waiting too long often leaves you cleaning up documentation mistakes.

How Can Corporate Law Firm Help?

Whether bidding for infrastructure PPPs, negotiating project documents or reviewing disputes, Corporate Law Firm can advise on all infrastructure PPP documentation, concession agreements, project risk assessments, interpretation of contracts, and commercial disputes/arbitration issues.

The role of the firm can start even before the submission of a bid.

Legal review may highlight risks such as unusual allocation of risk, exposure to ambiguous termination provisions and unfair dispute resolution provisions.

Execution stage support could include reviewing notices, waivers, decision letters, compensation claims, variation orders and defaults.

If a dispute has arisen, BK Singh Advocate can help you focus on the gathering of evidence, contractual entitlement and negotiation. Should talks break down, we can represent you in arbitration or court.

Each infrastructure project will have its own legal issues and no company should be advised using a generic boilerplate approach.

Building a highway under a HAM project model will present different legal issues to a logistics concession, municipal PPP or hospital DBFOT arrangement.
