By GK24 Editorial Team· Published · 6 min read

Roads, railway lines, ports, power stations, pipelines and broadband cables are the arteries of an economy, and they are also the most expensive assets a government buys. Since the reforms of 1991 India has followed a middle path: the asset stays publicly owned, while private money, project management and operating skill are brought in under a contract. That arrangement is the public-private partnership, or PPP. Examiners ask three things from this chapter, and only three: the names of the models, the body that clears a project, and the funds and master plans that pay for it. The subject is also in the news, because the Union Cabinet approved an Integrated Transport and Logistics Authority on 6 October 2026 to draw up a National Transport Master Plan, which shows that planning the network has become as large a task as building it.
What counts as infrastructure
Economic infrastructure serves production directly. It covers transport (roads, railways, ports, airports and inland waterways), energy (generation, transmission and pipelines), communication (telecom, broadband and the postal network) and irrigation. Social infrastructure serves people and improves the quality of labour: schools, hospitals, drinking water, sanitation and housing. The Department of Economic Affairs in the Ministry of Finance maintains the Harmonised Master List of Infrastructure Sub-sectors. A sector on that list can draw infrastructure lending from banks, borrow abroad on easier terms and receive funds earmarked for infrastructure, so entry into the list is itself a policy decision and not a mere classification.
Four features make infrastructure a special kind of investment, and a candidate who remembers these four words can answer most conceptual questions. The outlay is lumpy, because a bridge cannot be built in halves. The gestation period is long, so money is locked up for years before any revenue arrives. The benefits are external, since a new road helps traders who pay nothing for it. And many of these services are natural monopolies, where one network is cheaper than two, so prices have to be set by a regulator instead of by competition.
Why the private sector was brought in
Until 1991 infrastructure was almost wholly built by the State out of Budget and Plan outlays. The Expert Group on the Commercialisation of Infrastructure Projects, chaired by Rakesh Mohan, argued in its 1996 report that the gap between what the country needed and what the Budget could give had to be filled by commercial capital. Telecom was opened, the Electricity Act of 2003 unbundled generation from distribution, and the airports of Delhi and Mumbai passed to joint venture companies. In every such contract the public authority remains the owner. The private partner designs, finances, builds and operates the asset for a fixed concession period, earns from tolls or from payments by the authority, and hands the asset back at the end.
The PPP models an examiner asks about
| Model | How it works | Who carries the traffic risk |
|---|---|---|
| BOT (Toll) | The concessionaire builds the road and recovers its cost from user tolls | Private partner |
| BOT (Annuity) | The authority pays a fixed annuity at regular intervals; there is no toll income for the builder | Government |
| Hybrid Annuity Model | Forty per cent of the cost comes as a government grant in instalments during construction; the concessionaire funds the rest and is repaid as annuity with interest | Shared |
| DBFOT | Design, Build, Finance, Operate and Transfer, the full-service concession used for highways and airports | Private partner |
| TOT | Toll-Operate-Transfer: an already operating public highway is bundled and auctioned for an upfront concession fee | Private partner |
| EPC | Engineering, Procurement and Construction: a pure construction contract paid for by the government, so it is not a PPP at all | Government |
Two more terms belong here. A Model Concession Agreement is the standard contract that fixes how risk is divided, so that every project of a kind is bid on the same terms. The Swiss Challenge method is used when a private party sends in an unsolicited proposal: the authority publishes it and invites others to better it, and the original proposer gets a chance to match the best counter-offer.
Appraisal and the money behind the models
A central sector PPP project is appraised by the Public Private Partnership Appraisal Committee, chaired by the Secretary, Department of Economic Affairs. Where a project is good for the country but cannot pay for itself, the Viability Gap Funding scheme gives a capital grant of up to twenty per cent of the project cost from the Centre, and the sponsoring ministry or State may add up to twenty per cent more. India Infrastructure Finance Company Limited, set up in 2006, lends long term and refinances bank loans to such projects. The National Bank for Financing Infrastructure and Development was created by an Act of Parliament in 2021 as a development financial institution with paid-up capital of twenty thousand crore rupees and a grant of five thousand crore rupees from the Centre. The National Investment and Infrastructure Fund, set up in 2015, is a fund of funds in which the Government holds forty-nine per cent. Infrastructure Investment Trusts, regulated by SEBI since 2014, let ordinary investors hold units in completed, revenue-earning assets.
Master plans and programmes
- The National Infrastructure Pipeline, announced in the Budget of 2019-20, projected capital expenditure of about one hundred and eleven lakh crore rupees over the five years from 2019-20 to 2024-25, with the Centre and the States expected to put in roughly thirty-nine per cent each and the private sector the rest.
- The National Monetisation Pipeline was released by NITI Aayog in August 2021 to raise about six lakh crore rupees by leasing out operating central assets such as highways, transmission lines, railway stations and gas pipelines. Only brownfield assets are leased, and ownership is never sold.
- The PM Gati Shakti National Master Plan, launched on 13 October 2021, is a GIS platform that puts the project layers of the infrastructure ministries on one map so that a road, a pipeline and a railway line are planned together.
- The National Logistics Policy of September 2022 attacks the cost of moving goods through faster documentation, a unified logistics interface and multi-modal parks.
- Sector programmes complete the list: Bharatmala Pariyojana of 2017 for highways, Sagarmala of 2015 for port-led development, the UDAN regional connectivity scheme under the civil aviation policy of 2016, and the Eastern and Western Dedicated Freight Corridors built by the corporation set up for them in 2006.
Where PPP has stumbled
Many early road and power concessions were bid on traffic forecasts that never came true, and the losses reached the banks that had lent to them. Land acquisition and forest clearances delayed projects whose contracts assumed quick possession, and repeated renegotiation weakened the discipline of the bid. The Committee on Revisiting and Revitalising the PPP Model, chaired by Vijay Kelkar in 2015, held that risk must be carried by the party best able to manage it, that an independent sector regulator and a quick dispute resolution mechanism are needed, and that small projects should not be forced into the PPP form at all. The Hybrid Annuity Model, which splits the burden between the authority and the builder, is the practical answer that came out of that experience.
Exam Point of View
Questions come in four shapes. First, model identification: which model carries the traffic risk, and which of the four listed options is not a PPP at all, where EPC is the answer. Second, numbers: 40 per cent for the government share under HAM and 20 per cent for central viability gap funding are the two figures most often swapped in the options. Third, institutions: the PPPAC and its chair, IIFCL of 2006, NaBFID of 2021 and the NIIF of 2015. Fourth, scheme matching: NIP with the Department of Economic Affairs, NMP with NITI Aayog, Gati Shakti with the GIS master plan, Sagarmala with ports and Bharatmala with highways. The common trap is to attach the National Monetisation Pipeline to the Finance Ministry instead of NITI Aayog.

Practice MCQs on this topic
Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). Assertion (A): Government has launched the National Infrastructure Pipeline (NIP) for the period of 2020-30. Reason (R): The objective of NIP is to provide equitable access to infrastructure for all. Select the correct answer using the codes given below.
- A.Both (A) and (R) are true and (R) is the correct explanation of (A)
- B.Both (A) and (R) are true but (R) is not the correct explanation of (A)
- C.(A) is true but (R) is false
- D.(A) is false but (R) is true
Show answer
Explanation
The correct answer is D, (A) is false but (R) is true. The National Infrastructure Pipeline was announced in the Budget speech of 2019-20 and the task force under the Secretary, Department of Economic Affairs, drew it up for the five years from 2019-20 to 2024-25, with projected capital expenditure of about 111 lakh crore rupees. The period in the assertion, 2020-30, is therefore wrong, which rules out A and B, both of which treat the assertion as true. The reason, however, states the pipeline aim correctly: the NIP report sets out to give every citizen equitable access to world-class infrastructure, and that purpose is genuine. C is wrong because it reverses the position, calling the false assertion true and the true reason false. Read such pairs by testing the assertion first, because a false assertion settles the answer at once.
In the Hybrid Annuity Model used for national highway projects, what share of the project cost is provided by the government as a grant during construction?
- A.20 per cent
- B.40 per cent
- C.60 per cent
- D.100 per cent
Show answer
Explanation
The correct answer is B, 40 per cent. The Hybrid Annuity Model was adopted to revive road construction after both the toll and the annuity models ran into trouble. The authority releases forty per cent of the bid project cost as a construction grant in instalments while the work proceeds, and the concessionaire raises the remaining sixty per cent from its own funds and from lenders. That sixty per cent is returned after completion as a series of annuities with interest linked to a bank rate, and the toll is collected by the authority itself. A, twenty per cent, is the ceiling for central viability gap funding, not the HAM grant. C, sixty per cent, is the share the concessionaire brings, so the option inverts the split. D would make it an EPC contract rather than a partnership.
Under the Viability Gap Funding scheme, the capital grant from the Central Government is normally limited to what share of the total project cost?
- A.10 per cent
- B.20 per cent
- C.40 per cent
- D.50 per cent
Show answer
Explanation
The correct answer is B, 20 per cent. Viability Gap Funding is a one-time or deferred capital grant for a project that is economically necessary but commercially unviable, such as a rural road or a water supply line whose user charges can never repay the capital. The Department of Economic Affairs gives up to twenty per cent of the project cost, and the sponsoring ministry, State government or statutory authority may give a further twenty per cent, so support can reach forty per cent in total. That is why C is a tempting distractor: forty per cent is the combined ceiling, not the central share alone. A understates the scheme, and D is not available under it at all. Remember the pair of figures as twenty plus twenty.
Which body appraises public-private partnership projects of the central sector and is chaired by the Secretary, Department of Economic Affairs?
- A.Public Private Partnership Appraisal Committee
- B.Cabinet Committee on Economic Affairs
- C.Governing Council of NITI Aayog
- D.Finance Commission of India
Show answer
Explanation
The correct answer is A, the Public Private Partnership Appraisal Committee, usually written as PPPAC. It is the standing inter-ministerial committee that examines the concession agreement, the risk sharing and the financial structure of a central sector PPP proposal before approval, and its chair is the Secretary of the Department of Economic Affairs, with the secretaries of Expenditure, Legal Affairs, NITI Aayog and the sponsoring ministry as members. B, the Cabinet Committee on Economic Affairs, takes the final political decision on large projects but does not perform the technical appraisal. C is the body of chief ministers that guides NITI Aayog and has no project clearance role. D is a constitutional body under Article 280 that recommends the sharing of taxes between the Union and the States.
In the Toll-Operate-Transfer (TOT) model, what exactly is handed over to the private operator?
- A.A greenfield expressway that is still under construction
- B.An operating national highway stretch that already collects toll
- C.A plot of land for building a logistics park
- D.A railway line owned by a State government
Show answer
Explanation
The correct answer is B, an operating national highway stretch that already collects toll. Under TOT the authority bundles completed highway sections that have a proven traffic record and auctions the right to collect toll on them for a long concession, usually thirty years, against a single upfront payment. The money so received is used to build new roads, so TOT is a monetisation tool rather than a construction model, and the asset returns to the authority at the end. A describes a greenfield concession such as BOT or HAM, where the road has yet to be built and the traffic is only a forecast. C is a land lease, not a toll concession. D is outside the scheme, which covers national highways held by the central authority.
Which of the following is NOT a public-private partnership model?
- A.BOT (Annuity)
- B.Hybrid Annuity Model
- C.Engineering, Procurement and Construction
- D.Design, Build, Finance, Operate and Transfer
Show answer
Explanation
The correct answer is C, Engineering, Procurement and Construction. In an EPC contract the government owns the project, funds it from its own budget and simply buys construction services; the contractor is paid for the work done, keeps no operating responsibility and takes no revenue risk, so none of the defining features of a partnership is present. A, BOT on annuity, is a partnership in which the private partner builds with its own finance and is repaid in fixed instalments. B, the Hybrid Annuity Model, mixes a forty per cent construction grant with private finance for the rest. D, DBFOT, is the fullest form of concession, where the private partner designs, finances, builds, operates and finally transfers the asset. Examiners use this question to test the single idea that private finance and operation make a PPP.
The National Monetisation Pipeline, which lists operating central assets to be leased to private operators, was released by which organisation?
- A.Reserve Bank of India
- B.NITI Aayog
- C.Securities and Exchange Board of India
- D.Ministry of Road Transport and Highways
Show answer
Explanation
The correct answer is B, NITI Aayog. The National Monetisation Pipeline was released in August 2021 in two volumes, the second of which lists the assets ministry by ministry, with an aggregate monetisation potential of about six lakh crore rupees over four years from roads, power transmission, railways, pipelines, warehouses, stadiums and airports. Monetisation means leasing the right to operate a completed asset for a period; the ownership stays with the government and the asset comes back at the end. A, the Reserve Bank, is the monetary authority and has no role here. C regulates securities markets and would be involved only when an InvIT is listed. D is one of the ministries whose assets appear in the pipeline, not the body that prepared it.
The PM Gati Shakti National Master Plan, launched in October 2021, is best described as
- A.a GIS-based digital platform that brings the project layers of infrastructure ministries onto one map
- B.a concessional loan window for State road corporations
- C.a cess levied on freight carried by national highways
- D.a dedicated corridor for freight trains between Delhi and Mumbai
Show answer
Explanation
The correct answer is A, a GIS-based digital platform that brings the project layers of infrastructure ministries onto one map. Launched on 13 October 2021, PM Gati Shakti is an institutional answer to the old complaint that a road is dug up soon after it is laid because a pipeline or a cable was planned separately. Each infrastructure ministry puts its existing and planned assets on a common geographic information system, so that alignments, utility crossings and clearances are seen together before work begins, and multi-modal connectivity to economic zones is planned as one network. B is incorrect because the plan carries no lending window. C is invented; no such cess accompanies it. D describes the Western Dedicated Freight Corridor, a separate railway project. Note also that Gati Shakti is a planning platform and carries no money of its own.
The National Bank for Financing Infrastructure and Development (NaBFID) was established under an Act of Parliament passed in which year?
- A.2018
- B.2019
- C.2021
- D.2023
Show answer
Explanation
The correct answer is C, 2021. Infrastructure needs loans of twenty years or more, while a commercial bank takes deposits for a few years, and the mismatch between the two had crippled infrastructure lending after earlier development finance institutions were converted into banks. Parliament therefore passed the National Bank for Financing Infrastructure and Development Act in 2021, setting up NaBFID as a development financial institution with paid-up capital of twenty thousand crore rupees and a grant of five thousand crore rupees from the Central Government, with the mandate to lend long term and to deepen the bond and derivatives market for infrastructure. A and B are the years of other reforms and are offered only as near misses, and D is later than the Act.
Which committee submitted a report in 2015 on revisiting and revitalising the public-private partnership model of infrastructure?
- A.Committee chaired by Vijay Kelkar
- B.Committee chaired by C. Rangarajan
- C.Committee chaired by Bimal Jalan
- D.Committee chaired by M. Narasimham
Show answer
Explanation
The correct answer is A, the committee chaired by Vijay Kelkar. Set up by the Finance Ministry after a decade in which stalled road and power concessions turned into bad loans, the Kelkar Committee reported in 2015 that risk had been pushed on to whoever would accept it rather than on to the party best able to manage it. It asked for independent sector regulators, a specialised dispute resolution mechanism instead of years of litigation, better preparation of projects before bidding, and an end to the use of PPP for small works. B led committees on poverty estimation and on the Twelfth Plan approach. C headed a group on the Reserve Bank economic capital framework. D is remembered for the two banking sector reform committees of 1991 and 1998.
Frequently Asked Questions
What is the difference between EPC and PPP?
In an EPC contract the government pays the full cost and a contractor only engineers, procures and constructs the asset; the contractor brings no finance and runs no operating risk. In a PPP the private partner finances the project as well, operates it for a concession period of fifteen to thirty years, and earns from tolls or from annuity payments. EPC therefore appears in exam options as the item that is not a PPP model.
What is the Hybrid Annuity Model?
It is the road model that mixes the two older ones. The authority pays forty per cent of the project cost as a grant in instalments while construction goes on, and the concessionaire raises the remaining sixty per cent. After the road opens, the authority repays that sixty per cent as an annuity along with interest, and keeps the toll for itself. The traffic risk stays with the government and the construction risk with the builder.
Which committee reviewed India's PPP model?
The Committee on Revisiting and Revitalising the Public Private Partnership Model of Infrastructure, chaired by Vijay Kelkar, submitted its report in 2015. It recommended that each risk be allotted to the party best able to bear it, that an independent regulator be set up for each sector, that disputes be settled quickly instead of through long litigation, and that PPP not be used for small projects where the transaction cost outweighs the gain.
What does the National Monetisation Pipeline do?
Released by NITI Aayog in August 2021, it lists operating central assets such as national highways, power transmission lines, railway stations, gas pipelines and stadiums whose right to operate can be leased to private operators for a period, raising about six lakh crore rupees for fresh construction. Only brownfield assets that already earn revenue are offered, and the ownership of the asset is not transferred.
