Infrastructure & PPP Projects in India: FDI, BOT Models & Government Contracts

Why India's Infrastructure Boom Matters for Foreign Investors

India allocated over Rs 11.21 lakh crore (3.11% of GDP) for infrastructure development in the Union Budget 2025-26, making it the single largest area of public expenditure. The National Infrastructure Pipeline (NIP) envisages total investment of Rs 111 lakh crore across roads, railways, airports, ports, and urban infrastructure, with the private sector expected to contribute 21% of the total. For foreign investors, this translates into a massive, policy-backed opportunity to participate in some of the world's largest greenfield and brownfield infrastructure projects.

The government's three-year PPP project pipeline, announced in January 2026, includes 852 projects worth over Rs 17 lakh crore. With 100% FDI permitted via the automatic route in most infrastructure sub-sectors, foreign capital can flow into India's infrastructure without prior government approval in the vast majority of cases.

The sectoral breakdown of the NIP is telling: Energy accounts for 24% of projected capital expenditure, Roads 19%, Urban infrastructure 16%, and Railways 13%. Together, these four sectors represent approximately 70% of the total pipeline. Out of the total NIP of Rs 111 lakh crore, Rs 44 lakh crore (40%) worth of projects are under implementation, Rs 34 lakh crore (30%) are at the conceptualisation stage, and Rs 22 lakh crore (20%) are under development. The remaining 10% are completed projects being monetised or expanded. This pipeline ensures sustained deal flow for foreign investors over the next decade.

FDI Policy Framework for Infrastructure

Sectors Permitting 100% FDI Under Automatic Route

India's consolidated FDI policy permits 100% foreign direct investment under the automatic route in most infrastructure categories. This means no prior approval from the government or the Reserve Bank of India (RBI) is required. The key sectors include:

• Roads and highways: Construction, operation, and maintenance of national highways, state roads, expressways, toll roads, and bridges
• Railways: Construction, operation, and maintenance of suburban corridors, high-speed rail, dedicated freight corridors, and rolling stock manufacturing (100% automatic route since 2014)
• Ports and shipping: Development and operation of ports, inland waterways, and related logistics infrastructure
• Airports: Greenfield airports (100% automatic), existing airports (100% automatic up to 74%, government route beyond that for scheduled air transport services)
• Construction-development: Townships, housing, commercial premises, hospitals, educational institutions, and city-level infrastructure
• Power: Generation, transmission, and distribution (except atomic energy)
• Telecommunications: 100% automatic route for telecom infrastructure

Sectors With Restrictions

A few infrastructure-adjacent sectors carry FDI caps or require the government approval route:

PPP Models: BOT, HAM, BOLT, and Beyond

India deploys a range of Public-Private Partnership models for infrastructure delivery. Each model allocates risk, revenue, and ownership differently. Understanding these models is critical for foreign investors structuring their participation.

Build-Operate-Transfer (BOT) Toll

Under BOT-Toll, the private concessionaire finances, designs, builds, and operates the project for a concession period of 20-30 years. Revenue comes from tolls collected directly from users. The concessionaire bears full traffic risk, meaning revenue depends on actual usage volumes. At the end of the concession period, the asset transfers to the government authority.

The Ministry of Road Transport and Highways updated its model concession agreement for BOT road projects in 2025, introducing profit-and-loss sharing mechanisms tied to traffic data. This is expected to unlock approximately Rs 2 lakh crore in new projects by reducing downside risk for private investors.

Build-Operate-Transfer (BOT) Annuity

In BOT-Annuity, the concessionaire builds and operates the asset but receives fixed annuity payments from the government authority instead of collecting tolls. Traffic risk is borne by the government. This model is attractive for investors seeking predictable cash flows but yields are typically lower than BOT-Toll.

Hybrid Annuity Model (HAM)

HAM, introduced in January 2016 by the National Highways Authority of India (NHAI), is a hybrid between EPC and BOT models. Key features include:

• Government contribution: NHAI pays 40% of total project cost during the construction phase in equal milestones linked to construction progress
• Developer contribution: The road developer arranges the remaining 60% (typically 20-25% equity, balance through debt)
• Revenue model: After construction, the developer receives semi-annual annuity payments for 15-20 years, including interest on the balance investment
• Risk allocation: Construction risk lies with the developer; revenue and traffic risk lie with NHAI

HAM has become the dominant model for national highway construction, with approximately 30+ projects awarded by NHAI under this framework.

For foreign investors, HAM offers a compelling risk-return profile: the 40% government contribution during construction significantly reduces the developer's financing burden, while the annuity structure provides predictable cash flows for 15-20 years post-construction. The model was specifically designed to attract private capital back into highway development after several BOT-Toll projects faced traffic shortfall issues during 2012-2016.

Build-Own-Operate-Transfer (BOOT)

Under BOOT, the private entity designs, builds, owns, and operates the facility for 10-30 years before transferring it to the government. The key distinction from BOT is legal ownership during the concession period, which can provide better security for project lenders and foreign equity investors.

Build-Own-Lease-Transfer (BOLT)

In BOLT, the private developer builds and owns the asset, then leases it to the government authority. The government pays lease rentals during the lease period, after which ownership transfers. This model is commonly used in railway infrastructure and institutional buildings.

Toll-Operate-Transfer (TOT)

TOT is the government's asset monetisation model. NHAI bundles existing toll roads and auctions them to private operators who pay upfront for the right to collect tolls for a fixed period (typically 30 years). Foreign investors can participate through InvITs or direct bidding. A public Infrastructure Investment Trust (InvIT) is planned for launch in 2026 as part of the privatisation and asset monetisation roadmap.

Choosing the Right PPP Model

The choice of PPP model depends on the foreign investor's risk appetite, return expectations, and capital structure preferences. BOT-Toll offers the highest potential upside but carries full traffic risk and requires robust demand forecasting. HAM provides a middle ground with government co-funding and annuity payments. BOT-Annuity eliminates traffic risk entirely but offers lower returns. TOT is suitable for investors seeking operational assets with established traffic patterns and immediate cash generation. Foreign investors should also consider the regulatory environment: greenfield projects require more extensive approvals (environmental clearance, land acquisition, utility shifting) compared to brownfield or TOT transactions.

Structuring Foreign Investment: The SPV Approach

Infrastructure PPP projects in India are almost universally implemented through Special Purpose Vehicles (SPVs). When a government authority awards a concession, the concession agreement typically requires the winning bidder to form an SPV, which becomes the project company.

Why SPVs Matter for Foreign Investors

• Ring-fenced risk: The SPV isolates project risk from the parent company's balance sheet
• Transparent cash flows: Lenders and equity investors have direct visibility into project-level financials
• Regulatory compliance: The SPV structure allows clean FEMA compliance, with foreign investment flowing directly into the project entity
• Exit flexibility: Equity stakes in the SPV can be transferred to other investors (subject to lock-in periods in the concession agreement)

FDI into Infrastructure SPVs

100% FDI in equity of SPVs in the PPP sector is permitted under the automatic route for most infrastructure sectors. The foreign investor must:

1. Incorporate or invest in an Indian private limited company or LLP structured as the SPV
2. File FC-GPR with the RBI within 30 days of share allotment
3. Comply with FDI pricing guidelines for share issuance
4. File the annual FLA return with the RBI by July 15 each year
5. Ensure the SPV's Memorandum of Association permits the infrastructure activity

For end-to-end guidance on entity formation, see our foreign subsidiary registration service.

Typical SPV Capital Structure for PPP Projects

Infrastructure SPVs in India typically follow a debt-equity ratio of 70:30 to 80:20. The equity component comes from the project sponsors (domestic and foreign), while debt is raised from Indian banks, development financial institutions (DFIs), and multilateral agencies like the Asian Development Bank (ADB) or International Finance Corporation (IFC). Foreign equity investors can structure their investment as share capital, share premium, or a combination of equity and compulsorily convertible debentures (CCDs). The choice of instrument affects pricing flexibility, exit mechanics, and tax treatment.

A common structure for foreign participation involves a holding company in Singapore or Mauritius investing into the Indian SPV, taking advantage of favourable DTAA provisions. However, post-GAAR (General Anti-Avoidance Rules) implementation, the holding company must demonstrate commercial substance beyond merely routing investment.

Government Contract Bidding: Process for Foreign Companies

Foreign companies can participate in Indian government infrastructure tenders, but the process involves specific eligibility requirements and registration obligations.

Eligibility and Registration

Most infrastructure tenders are published on the Central Public Procurement Portal (CPPP) at eprocure.gov.in or on sector-specific portals (e.g., NHAI's portal for highway projects). Foreign companies must typically:

• Register on the relevant e-procurement portal
• Obtain a Digital Signature Certificate (DSC) from a licensed Indian Certifying Authority
• Provide evidence of technical qualification (past project experience, turnover, net worth)
• Submit bid security (Earnest Money Deposit) typically 1-5% of the estimated project cost

Land Border Country Restrictions

Since 2020, bidders from countries sharing land borders with India (China, Pakistan, Bangladesh, Nepal, Bhutan, Myanmar, Afghanistan) face additional restrictions under Press Note 3 (2020). They must obtain registration and security clearance from competent Indian authorities before participating in government procurement.

Any future relaxation of the Press Note 3 framework would be notified by DPIIT; investors should check the latest DPIIT press notes before structuring deals.

Make in India and Local Content

Government procurement increasingly favours domestic suppliers through the Make in India initiative. Key procurement preferences include:

• Class I Local Supplier: Minimum 50% local content, gets highest preference
• Class II Local Supplier: Minimum 20% local content, gets secondary preference
• Foreign bidders: Can participate but may be matched at L1 (lowest bid) prices only if local suppliers are unable to meet requirements

Foreign companies often participate through Indian joint ventures or wholly-owned subsidiaries to qualify as local suppliers.

Bid Evaluation and Award

PPP project bids are typically evaluated on a two-envelope system: technical qualification (envelope 1) and financial bid (envelope 2). Only technically qualified bidders have their financial bids opened. For BOT-Toll projects, the financial bid is usually the lowest toll rate or highest premium/revenue share offered to the government. For HAM projects, it is typically the lowest bid project cost. The awarded concessionaire must execute the concession agreement and provide a performance bank guarantee (typically 5-10% of project cost) before the contract becomes effective.

Foreign companies must allow a minimum of four weeks for bid preparation when international participation is contemplated, as prescribed by India's General Financial Rules (GFR). Recent policy changes under the 2025 Union Budget have further streamlined concession structuring and promoted uniform risk-allocation practices across PPP contracts.

Viability Gap Funding (VGF): Bridging the Financial Gap

The Viability Gap Funding scheme, administered by the Department of Economic Affairs, provides capital grants to economically desirable but commercially unviable PPP projects. This is particularly relevant for foreign investors evaluating projects in social infrastructure sectors.

VGF Structure

• Traditional infrastructure: VGF up to 40% of total project cost (Central Government contribution up to 20%, state/sponsoring authority up to 20%)
• Social infrastructure (health, education, water, waste): VGF up to 60% of total project cost (30% Central, 30% State)

As of 2025, 67 projects with total project cost of Rs 45,802 crore have received final approval under the VGF scheme, with Rs 7,682 crore in VGF approved and Rs 4,847 crore already disbursed.

India Infrastructure Project Development Fund (IIPDF)

The IIPDF provides funding for early-stage activities including feasibility studies, project structuring, and transaction advisory for PPP projects. This can reduce the upfront cost for foreign companies evaluating potential investments.

Sector-Specific Opportunities for Foreign Investors

Roads and Highways

India aims to develop 66 expressways spanning 15,300 km under the Bharatmala Pariyojana programme. The highway sector offers multiple entry points for foreign capital: BOT-Toll and HAM for greenfield projects, TOT for operational assets, and InvITs for portfolio investment.

Railways

With 100% FDI permitted under the automatic route, the railway sector offers opportunities in suburban corridor development, station redevelopment (150+ stations identified), rolling stock manufacturing, and dedicated freight corridors.

Airports

India has awarded six brownfield airports (Ahmedabad, Lucknow, Mangalore, Jaipur, Guwahati, Thiruvananthapuram) under the PPP model, with more rounds expected. Greenfield airports like Navi Mumbai and Nojehl are under development through PPP concessions.

Ports and Waterways

The Maritime India Vision 2030 targets port capacity of 3,300+ MTPA. The Sagarmala programme includes 600+ projects worth over Rs 6 lakh crore, many structured as PPPs with open eligibility for foreign investors.

Smart Cities and Urban Infrastructure

The Smart Cities Mission covers 100 cities with integrated infrastructure projects spanning urban transport, water supply, sewage treatment, solid waste management, and digital infrastructure. Foreign investors can participate through SPVs established at the city level. These projects frequently use PPP models for specific components, offering smaller-ticket investment opportunities compared to highway or airport concessions.

Renewable Energy Infrastructure

India targets 500 GW of non-fossil fuel energy capacity by 2030. Solar parks, wind farms, and battery energy storage systems offer infrastructure-like investment characteristics with long-term power purchase agreements (PPAs) providing revenue certainty. A dedicated Viability Gap Funding scheme for offshore wind energy projects was approved with an outlay of Rs 7,453 crore to support 1 GW capacity installation. FDI up to 100% is permitted under the automatic route for renewable energy generation.

Tax Implications for Foreign Investors in Infrastructure

Foreign investors in Indian infrastructure projects must navigate several tax considerations:

• Corporate tax: Infrastructure SPVs are generally taxed at 22% (plus cess and surcharge, effective rate ~25.17%) under Section 115BAA for domestic companies. The 15% concessional rate under Section 115BAB for new manufacturing companies was available only to companies that commenced manufacturing by 31 March 2024; that eligibility window has closed.
• Withholding tax on dividends: 20% (reduced under applicable DTAAs). For example, US investors pay 15%, Singapore investors pay 10%
• Transfer pricing: Arm's length pricing required for all transactions between the SPV and its foreign parent or affiliates
• Tax holiday under Section 80-IA: Infrastructure companies can claim 100% deduction of profits for 10 consecutive years out of the first 20 years of operation (being phased out under the new regime)
• GST: Infrastructure projects attract 12-18% GST on construction services, with input tax credit available

For detailed tax planning, see our tax advisory services.

Dispute Resolution and Exit Mechanisms

Infrastructure concession agreements in India include dispute resolution mechanisms that foreign investors should understand before committing capital:

• Conciliation and arbitration: Most model concession agreements provide for disputes to be resolved through arbitration under the Arbitration and Conciliation Act, 1996. Institutional arbitration (e.g., through the Indian Council of Arbitration or Singapore International Arbitration Centre) is increasingly common
• Bilateral Investment Treaties (BITs): India terminated most of its older BITs in 2017 and introduced a new Model BIT. Foreign investors should verify whether their home country has a valid BIT with India to access international arbitration protections
• Exit routes: Foreign investors can exit infrastructure SPVs through equity transfer to other investors (subject to lock-in periods, typically 1-2 years post-commercial operation), listing on Indian stock exchanges, or strategic sale. InvIT listing is emerging as a preferred exit route for portfolio monetisation
• Termination payments: Concession agreements typically provide for termination payments in case of government default, force majeure, or concessionaire default, calculated based on outstanding debt and equity invested
