Infrastructure — UPSC Economy Notes

1. Structure of the Power Sector

Value chain: generation → transmission (inter-state by POWERGRID and private players; intra-state by state utilities) → distribution (state discoms and a few private discoms such as in Delhi, Mumbai, Odisha).

Constitutional position: electricity is in the Concurrent List (Entry 38, List III); the Electricity Act, 2003 de-licensed generation and created the CERC and state regulatory commissions.

One Nation One Grid: all regional grids were synchronised in December 2013, creating one of the world's largest synchronous grids.

2. Capacity Mix and the Energy Transition

In June 2025 non-fossil sources crossed 50% of installed capacity, five years ahead of the 2030 NDC goal.

As of 31 July 2026 non-fossil capacity was about 300 GW (solar about 165 GW, wind about 58 GW, hydro about 57 GW, bio-power about 12 GW, nuclear about 9 GW), against a target of 500 GW by 2030.

Coal still generates roughly three-quarters of electricity, because solar and wind have low capacity utilisation; storage and flexible coal plants are needed to balance the grid.

Green Energy Corridors build transmission for renewable-rich states; PM Surya Ghar Muft Bijli Yojana (2024) supports rooftop solar for 1 crore households.

3. Discoms: the Weakest Link

Problems: high AT&C losses (theft, poor billing and collection), tariffs below cost, delayed subsidy payments by state governments, and cross-subsidy that makes industrial power expensive.

ACS–ARR gap: the gap between the Average Cost of Supply and the Average Revenue Realised per unit is the key measure of discom viability.

Past bailouts: Financial Restructuring Plan (2012) and UDAY (2015), under which states took over 75% of discom debt; losses later returned.

Revamped Distribution Sector Scheme (RDSS, 2021): outlay ₹3,03,758 crore with gross budgetary support of ₹97,631 crore; funds are released only when discoms meet loss-reduction milestones. Targets: AT&C losses of 12–15% and zero ACS–ARR gap; about 25 crore smart prepaid meters.

Late Payment Surcharge Rules, 2022 let discoms clear legacy dues to generators in instalments, improving payment discipline.

4. National Green Hydrogen Mission (2023)

Approved in January 2023 with an outlay of ₹19,744 crore; target of 5 million tonnes of green hydrogen production a year by 2030.

SIGHT programme (Strategic Interventions for Green Hydrogen Transition) gives incentives for electrolyser manufacturing and green hydrogen production; pilots cover steel, mobility and shipping.

The Green Hydrogen Standard (notified by MNRE, August 2023) treats hydrogen as green if well-to-gate emissions are not more than 2 kg CO₂-equivalent per kg of hydrogen.

Uses: replacing grey hydrogen in refineries and fertiliser plants, green ammonia exports, and green steel.

5. Other Recent Steps

Union Budget 2025-26 announced a Nuclear Energy Mission (₹20,000 crore for small modular reactors) towards 100 GW nuclear capacity by 2047; Budget 2026-27 allotted ₹20,000 crore over five years for carbon capture, utilisation and storage.

Practice

UPSC-style: "Discoms are the Achilles' heel of India's power sector." Examine the causes and evaluate the RDSS approach.

1. Role and Problems

Railways carry coal, iron ore, cement, foodgrains and fertilisers at lower cost and lower emissions per tonne-km than trucks.

Rail's share of freight has fallen to under 30% because of congested mixed-traffic lines, high freight tariffs (used to cross-subsidise passenger fares) and poor last-mile links.

The National Rail Plan 2030 aims to raise rail's share of freight to about 45%.

The operating ratio (working expenses per ₹100 earned) has stayed close to 98%, leaving little internal surplus for investment; capex is funded mainly by gross budgetary support.

The separate Railway Budget was merged with the Union Budget in 2017 (Bibek Debroy Committee recommendation).

2. Dedicated Freight Corridors (DFCs)

Built by DFCCIL (set up in 2006) to separate freight from passenger traffic, allowing heavier, faster and double-stack trains.

Eastern DFC (about 1,337 km, Ludhiana–Sonnagar, World Bank-funded) carries mainly coal; Western DFC (about 1,506 km, Dadri–JNPT, JICA-funded) carries containers to western ports.

The Union Budget 2026-27 announced a new DFC connecting Surat to Dankuni.

3. Modernisation and Speed

Vande Bharat Express: indigenous semi-high-speed train set built by the Integral Coach Factory, Chennai; first service New Delhi–Varanasi in February 2019; sleeper versions are being added.

Mumbai–Ahmedabad High Speed Rail (about 508 km) uses Japanese Shinkansen technology through NHSRCL; Budget 2026-27 announced seven more high-speed corridors.

Electrification of the broad-gauge network is nearly complete, cutting diesel imports and emissions; Indian Railways targets net-zero carbon emissions by 2030.

4. Safety: Kavach

Kavach is an indigenous Automatic Train Protection system developed by RDSO, certified to Safety Integrity Level 4; it applies brakes automatically if the driver fails to act on a red signal or over-speeds, and prevents head-on collisions.

It was adopted as the national ATP system in 2020; Kavach version 4.0 was approved in 2024, and rollout across the network is in progress.

5. Private Participation (PPP)

Station redevelopment under the Amrit Bharat Station Scheme, Gati Shakti Multi-Modal Cargo Terminals, private wagon and freight-terminal investment, and port-connectivity rail projects through joint ventures.

The 2020 plan to run private passenger trains on 109 route pairs drew little interest, showing the risk of PPP where the public operator controls track access and pricing.

Practice

UPSC-style: How can Dedicated Freight Corridors help India reduce logistics costs? What prevents Indian Railways from regaining its freight share?

1. The Road Network

Total network of over 60 lakh km; National Highways (about 1.46 lakh km) are only about 2% of length but carry around 40% of traffic.

National highways are a Union subject (Entry 23, List I); NHAI (set up under the NHAI Act, 1988) develops and maintains them for the Ministry of Road Transport and Highways.

Rural roads are built under PMGSY (2000); PMGSY-IV (2024) targets connectivity for about 25,000 unconnected habitations.

2. Bharatmala Pariyojana

Approved in October 2017; Phase I covered about 34,800 km and replaced the National Highways Development Project (NHDP, 1998) approach of building only individual stretches.

Components: economic corridors, inter-corridor and feeder routes, national corridor efficiency improvement, border and international connectivity roads, coastal and port connectivity roads, and greenfield expressways.

The corridor approach uses origin–destination freight studies to pick routes; the CAG (2023) flagged large cost escalation in Phase I.

3. Financing Models

EPC: government pays the full cost; contractor only builds.

BOT (Toll/Annuity): private developer finances, builds and operates, recovering cost through tolls or annuities; it collapsed after 2012 due to traffic risk and land delays.

Hybrid Annuity Model (HAM, 2016): government pays 40% of project cost during construction and the rest as annuities with interest over the concession period; the government keeps the toll (traffic) risk.

Toll-Operate-Transfer (TOT, 2018): completed, toll-earning highways are leased to investors for an upfront payment.

4. Asset Monetisation

Idea: lease operating public assets (brownfield) to private investors for a fixed period, keep ownership, and use the proceeds to build new assets (capital recycling).

NHAI uses TOT bundles, the NHAI InvIT (listed 2021) and toll securitisation.

National Monetisation Pipeline (NMP) 1.0 (2021): ₹6 lakh crore over FY22–FY25, roads the largest sector. NMP 2.0, launched in February 2026, estimates ₹16.72 lakh crore over five years, with highways about ₹4.42 lakh crore.

5. Tolling and Safety

FASTag became mandatory in February 2021; an annual FASTag pass for private cars started on 15 August 2025, and satellite-based (GNSS) tolling is being piloted.

India records about 1.7 lakh road deaths a year, the highest in the world; the Motor Vehicles (Amendment) Act, 2019 raised penalties.

Practice

UPSC-style: Explain the Hybrid Annuity Model. How does it differ from BOT and EPC in sharing risks between the government and private developers?

1. Port System

Major ports (12, under the Union; Entry 27, List I) and non-major ports (about 200, under state maritime boards; Entry 31, List III). Vadhavan (Maharashtra), approved in 2024, will be the 13th major port and one of the world's deepest.

Non-major ports (Mundra, Krishnapatnam, etc.) now handle a large and growing share of cargo, much of it in private hands.

Major Port Authorities Act, 2021 replaced the Major Port Trusts Act, 1963, giving boards power to fix tariffs and approve PPP projects.

Vizhinjam (Kerala), commissioned in 2025, is India's first deep-water container transshipment port, reducing dependence on Colombo and Singapore.

2. Sagarmala Programme (2015)

Pillars: port modernisation, port connectivity (rail, road, inland waterways), port-led industrialisation (coastal economic zones) and coastal community development; coastal shipping was added later.

Long-term plans: Maritime India Vision 2030 (2021) and Maritime Amrit Kaal Vision 2047 (2023).

Inland waterways: 111 National Waterways under the National Waterways Act, 2016; Budget 2026-27 plans to operationalise 20 new national waterways in five years.

3. Efficiency Gains

Average ship turnaround time at major ports has fallen sharply over the last decade through mechanisation, deeper drafts and digital systems (Port Community System, Sagar Setu).

Indian ports featured strongly in the World Bank's Container Port Performance Index 2023, with Visakhapatnam in the global top 20.

4. Shipping and Shipbuilding

India's share in global shipbuilding is below 1% (China, South Korea and Japan dominate), and Indian-flagged ships carry only a small share of India's own trade, so freight payments to foreign lines are a large services import.

Package of September 2025 (₹69,725 crore): Shipbuilding Financial Assistance Scheme extended to 2036 (₹24,736 crore); a Maritime Development Fund of ₹25,000 crore; a Shipbuilding Development Scheme (₹19,989 crore) for shipbuilding clusters; and a National Shipbuilding Mission.

The package aims at about 4.5 million gross tonnage of annual shipbuilding capacity; large ships were also given infrastructure status for cheaper long-term finance.

Cochin Shipyard built INS Vikrant, India's first indigenous aircraft carrier (commissioned 2022).

5. Challenges

Poor hinterland connectivity, high logistics costs, dependence on foreign transshipment hubs, limited ship finance and high cost of capital for shipyards.

Practice

UPSC-style: "Port-led development can be a growth engine for India's coastal states." Discuss with reference to the Sagarmala programme.

1. Institutions and Laws

Ministry of Civil Aviation makes policy; DGCA is the safety regulator; Airports Authority of India (AAI) owns and runs most airports and air navigation; AERA regulates tariffs at major airports.

The Bharatiya Vayuyan Adhiniyam, 2024 replaced the Aircraft Act, 1934.

National Civil Aviation Policy, 2016 set the framework for regional connectivity, MRO, cargo and the 5/20 rule relaxation for international flights.

2. UDAN (Ude Desh ka Aam Nagrik)

Regional Connectivity Scheme launched in 2016; first flight Shimla–Delhi in April 2017.

Mechanism: airlines bid for un-served or under-served routes; about half the seats are capped at an affordable fare, and the gap is met by Viability Gap Funding shared by the Centre (through a levy on other flights) and states; airlines get exclusivity on the route for three years.

Extensions: helicopters and seaplanes, Krishi UDAN (farm cargo), and a modified UDAN announced in Budget 2025-26 to add 120 new destinations over ten years.

Problems: many routes closed after the subsidy period ended; small airlines failed; poor airport readiness in remote areas.

3. Airports and PPP

The number of operational airports roughly doubled after 2014 to about 160.

PPP waves: Delhi and Mumbai (joint ventures, 2006); Hyderabad and Bengaluru (greenfield BOOT); six AAI airports (Ahmedabad, Jaipur, Lucknow, Guwahati, Thiruvananthapuram, Mangaluru) leased in 2019-20 on a per-passenger-fee basis.

Greenfield Airports Policy, 2008 governs new airports such as Navi Mumbai and Noida (Jewar).

Concerns: concentration of several airports with one private group; AERA's tariff setting and user charges.

4. Airlines and Costs

Aviation turbine fuel (ATF) is about 40% of airline costs and is outside GST, attracting high state VAT in many states.

Repeated failures (Kingfisher 2012, Jet Airways 2019, Go First 2023) left two groups controlling most of the domestic market.

Air India was privatised to the Tata group in January 2022.

MRO and leasing: GST on MRO services was cut to 5% and aircraft leasing is being built up at GIFT City IFSC to reduce dependence on Ireland and Singapore.

Practice

UPSC-style: Assess the UDAN scheme's success in making air travel affordable and improving regional connectivity.

1. Evolution

National Telecom Policy 1994 and New Telecom Policy 1999 opened the sector and moved licences to revenue sharing; TRAI (1997) regulates tariffs and quality.

The 2G spectrum case (2012) led to spectrum allocation by auction; the 2016 entry of a low-price operator triggered a price war and consolidation.

The Supreme Court's 2019 AGR judgment (adjusted gross revenue to include non-telecom income) created large dues; the 2021 telecom reforms redefined AGR prospectively, allowed a moratorium on dues and permitted 100% FDI through the automatic route.

2. Telecommunications Act, 2023

Replaced the Indian Telegraph Act, 1885 and the Indian Wireless Telegraphy Act, 1933.

Spectrum by auction as the rule, with administrative allocation for listed uses such as satellite communication; powers to intercept or suspend services on grounds of public safety; right-of-way rules for laying infrastructure.

The Universal Service Obligation Fund was renamed Digital Bharat Nidhi and can fund research and new technologies besides rural connectivity.

3. 5G and Beyond

The 2022 spectrum auction raised about ₹1.5 lakh crore; 5G services began on 1 October 2022, one of the fastest rollouts in the world.

Uses: fixed wireless broadband, private captive networks for industry, smart cities and telemedicine.

Bharat 6G Vision (2023) aims for India to be a leading contributor to 6G standards by 2030; a telecom PLI scheme supports domestic equipment manufacturing.

4. BharatNet and Rural Broadband

Started in 2011 as the National Optical Fibre Network to connect all gram panchayats with optical fibre; implemented by Bharat Broadband Network Ltd (BBNL, since merged into BSNL).

The amended BharatNet programme (2023, about ₹1.39 lakh crore) extends fibre to all inhabited villages and uses a utilisation-based model with a village-level entrepreneur.

PM-WANI (2020) allows public data offices to offer Wi-Fi without a licence.

5. Data Centres and Digital Backbone

Data centres were given infrastructure status (2022); Budget 2026-27 announced a tax holiday until 2047 for foreign firms providing global cloud services from Indian data centres.

Submarine cable landing stations (mostly Mumbai and Chennai) and the Chennai–Andaman cable (2020) strengthen international and island connectivity.

6. Challenges

Low average revenue per user, high spectrum costs and debt; rural–urban and gender digital divide; dependence on imported network equipment; internet shutdowns.

Practice

UPSC-style: How does the Telecommunications Act, 2023 change the regulatory framework for the sector? Discuss its implications for satellite broadband.

1. Why Urban Infrastructure Matters

About 31% of Indians lived in urban areas in 2011, and the share is rising; cities are engines of jobs, services and innovation.

The 74th Constitutional Amendment (1992) listed 18 functions for municipalities (Twelfth Schedule), but most states have not devolved matching funds and staff.

2. Flagship Missions

Smart Cities Mission (June 2015): 100 cities chosen by competition; projects run through Special Purpose Vehicles; Integrated Command and Control Centres in all 100 cities; the mission was extended to 31 March 2025.

AMRUT (2015, 500 cities) and AMRUT 2.0 (October 2021, total outlay about ₹2.99 lakh crore): universal tap water in all statutory towns, sewerage in 500 cities, water-body rejuvenation and a 'Pey Jal Survekshan'.

Other missions: Swachh Bharat Mission–Urban 2.0, PMAY–Urban 2.0 (2024) and PM e-Bus Sewa (2023, 10,000 electric buses).

3. Metro Rail and Urban Transport

India's operational metro network crossed about 1,000 km across more than 20 cities by 2025, among the largest in the world.

Metro Rail Policy, 2017 requires a comprehensive mobility plan, an alternatives analysis, last-mile connectivity and private participation; RRTS (Delhi–Meerut Namo Bharat) links satellite towns.

Many metros carry far fewer riders than projected because of poor feeder buses and walkability.

4. Municipal Finance

Municipal revenues are about 1% of GDP, far below many emerging economies; property tax is under-assessed and user charges rarely cover costs.

Tools: GIS-based property tax, Value Capture Finance (2017), Transit-Oriented Development, municipal bonds (Pune 2017 and others) and PPPs.

Budget 2025-26 announced a ₹1 lakh crore Urban Challenge Fund for 'cities as growth hubs' and creative redevelopment.

Budget 2026-27: mapping of City Economic Regions with ₹5,000 crore per region over five years, and an incentive of ₹100 crore for a single municipal bond issue above ₹1,000 crore.

The 16th Finance Commission (2026-31) recommended grants for urban local bodies, including a special infrastructure component for wastewater management and an urbanisation premium.

5. Governance Issues

Fragmentation between municipalities, development authorities and parastatals; weak mayors; Metropolitan Planning Committees rarely functional; urban flooding from encroached drains and lakes.

Practice

UPSC-style: "Indian cities have missions but not money." Examine the state of municipal finances and suggest reforms.

1. The Financing Problem

Asset–liability mismatch: banks lend from short-term deposits, but infrastructure loans run 15–25 years; heavy bank lending to power and roads after 2008 contributed to the twin balance sheet problem.

A shallow corporate bond market, land and clearance delays, and contract disputes raise risk and cost of capital.

2. Public Capex and the Pipeline

National Infrastructure Pipeline (NIP): launched in December 2019 with projected investment of about ₹111 lakh crore over FY2020–25, shared roughly 39% Centre, 40% states and 21% private sector; energy, roads, urban and railways had the largest shares.

Union capital expenditure rose steeply after 2020; Budget 2026-27 raised public capex to about ₹12.2 lakh crore (from ₹11.2 lakh crore), and gives states ₹1.85 lakh crore of 50-year interest-free capex loans.

The Harmonised Master List of infrastructure sub-sectors decides which projects get infrastructure lending benefits.

3. Institutions

NaBFID (National Bank for Financing Infrastructure and Development) was set up under the NaBFID Act, 2021 as a development finance institution with an initial ₹20,000 crore capital; it is regulated by the RBI as an All-India Financial Institution.

IIFCL (2006) provides long-term loans and credit enhancement; the National Investment and Infrastructure Fund (NIIF) (2015) brings in sovereign and pension fund equity.

Viability Gap Funding (2006) gives up to 20% of project cost from the Centre (plus up to 20% from the sponsoring authority) for socially needed but commercially weak PPPs; Budget 2026-27 proposed an Infrastructure Risk Guarantee Fund to give comfort to private developers.

4. Market Instruments

InvITs and REITs (SEBI regulations, 2014) pool income-generating assets (toll roads, transmission lines, offices) and distribute most cash flows to unit holders, letting developers recycle capital.

Other sources: infrastructure debt funds, green and municipal bonds, external commercial borrowings, and multilateral lenders.

Asset monetisation: NMP 1.0 (₹6 lakh crore, 2021) and NMP 2.0 (₹16.72 lakh crore over five years, launched February 2026).

5. PM Gati Shakti National Master Plan (2021)

Launched on 13 October 2021 as a GIS-based digital platform (built with BISAG-N) on which ministries and states plan projects together.

Seven engines: roads, railways, airports, ports, mass transport, waterways and logistics infrastructure; a Network Planning Group and an Empowered Group of Secretaries review projects.

It is complemented by the National Logistics Policy (September 2022), which aims to cut logistics costs towards global benchmarks.

Practice

UPSC-style: Why has private investment in Indian infrastructure remained weak despite high public capex? Suggest measures to crowd in private capital.
