Infrastructure — Practice

Question 1

Classify each of the following as economic or social infrastructure and give a reason:
(a) A dedicated freight corridor connecting Mumbai and Delhi
(b) A government primary school in a rural village
(c) A solar power plant supplying electricity to industries
(d) A primary health centre (PHC) in a tribal district

Accepted Answer

(a) **Economic Infrastructure** — freight corridor directly supports production and trade by reducing logistics costs for industries. It increases the productivity of the whole economy.

(b) **Social Infrastructure** — a school develops human capital by educating children. Education enhances future worker productivity but is not directly an input to current production.

(c) **Economic Infrastructure** — electricity supply is a direct input to industrial production. Reliable power reduces generator costs and increases factory output.

(d) **Social Infrastructure** — a PHC improves health outcomes, reducing worker absenteeism and building human capital. Healthcare is an investment in people, not directly in production.

Question 2

India loses approximately 20-22% of all electricity it generates through Transmission and Distribution (T&D) losses. (a) Explain two main causes of T&D losses. (b) If India generated 1,600 billion units (BU) of electricity in 2023-24, how many units were lost to T&D? (c) Suggest two policy measures to reduce these losses.

Accepted Answer

(a) **Two causes of T&D losses**:
(i) **Electricity theft (commercial losses)**: Illegal connections, meter tampering, and corruption in DISCOMs account for ~10% of total losses. This is highest in UP, Rajasthan, and Bihar.
(ii) **Technical losses**: Ageing transmission lines, inadequate transformer capacity, and long-distance low-voltage distribution cause energy dissipation as heat. Rural areas with long distribution lines face higher technical losses.

(b) T&D loss calculation:
Lost units = 20% of 1,600 BU = **320 billion units** lost.
At average tariff of ₹5/unit, this represents ₹1,600 crore in revenue lost DAILY — ₹5.84 lakh crore per year.

(c) **Policy measures**:
(i) Smart meters: prepaid digital meters eliminate theft and give real-time consumption data. India's Smart Meter National Programme targets 250 million smart meters.
(ii) Distribution infrastructure upgrading: higher-voltage distribution lines reduce technical losses; underground cabling eliminates theft from overhead wires.

Question 3

The Indian government uses the Public-Private Partnership (PPP) model extensively for infrastructure. Explain the PPP model and evaluate its advantages and limitations using specific examples from India.

Accepted Answer

**What is PPP**: A Public-Private Partnership is a long-term contract between the government and a private company to build, finance, operate, and/or maintain infrastructure. The government provides land, clearances, and sometimes viability gap funding (VGF); the private sector provides capital, technology, and management efficiency.

**Types in India**:
- **Build-Operate-Transfer (BOT)**: Private company builds + operates for contract period (20–30 years) + transfers to government. Example: NH toll roads (NHAI contracts).
- **Build-Own-Operate (BOO)**: Private company builds and permanently owns. Example: private airports (GMR-Delhi, Hyderabad).
- **Design-Build-Finance-Operate (DBFO)**: Full lifecycle private management. Example: metro rail systems (Hyderabad Metro).

**Advantages**:
(i) **Mobilises private capital**: Government deficit limits public spending; PPP attracts private and foreign investment. India's NIP (National Infrastructure Pipeline, ₹111 lakh crore, 2019–25) relies on 30% private funding.
(ii) **Operational efficiency**: Private operators reduce costs and improve service quality vs public utilities (compare Delhi Metro under DMRC's semi-PPP with older state-run bus services).
(iii) **Risk transfer**: Construction, revenue, and operational risks shift to the private party — reducing contingent liabilities on the government budget.

**Limitations**:
(i) **Profitability requirement**: Private firms focus on profitable routes (Delhi-Mumbai corridor), not essential but loss-making services (rural roads, tribal areas). Social equity suffers.
(ii) **Regulatory capture**: Private operators lobby against tariff regulation. Example: airport charges at GMR-Delhi are among the world's highest, burdening passengers.
(iii) **Renegotiation risk**: ~30% of Indian PPP contracts have been renegotiated after completion. Private parties take profits in good times and demand government bailouts in bad times ('heads I win, tails you lose').

**Conclusion**: PPP works best for urban, commercially viable infrastructure (airports, metro, toll roads) but fails for rural and social infrastructure where pricing is difficult. India needs PPP alongside direct public investment, not as a replacement.
