Solar industry’s wish list for Union Budget

1. At a Glance

• India's solar sector has emerged as the second-largest generator by installed capacity in the domestic power mix, having grown from 3 GW (2014) to 129.92 GW (October 2025)—a ~43-fold increase in a decade. [1]
• Pre-budget demands from industry bodies (NSEFA, SESI) centre on three pillars: PLI extension to ingots, PM-KUSUM second instalment, and Viability Gap Funding (VGF) for energy storage. [4]
• Directly relevant to GS-III (Infrastructure, Energy, Economy) and GS-II (Government Schemes); frequently tested in both Prelims and Mains.
• India's 500 GW non-fossil capacity target by 2030 (NDC commitment) makes solar budget allocations a recurring examination anchor.

2. Why in the News

• January 13, 2026 (The Hindu BusinessLine): Industry bodies — the National Solar Energy Federation of India (NSEFA) and the Solar Energy Society of India (SESI) — submitted a pre-Budget wish list ahead of Union Budget 2026–27, demanding: [4]
• A new/enhanced PLI scheme for solar ingot manufacturing.
• Second instalment of the PM-KUSUM scheme.

• Viability Gap Funding (VGF) for energy storage to complement solar deployment.

• Context: India's solar capacity crossed 100 GW in 2024 and hit 129.92 GW by October 2025, making sector-specific budgetary support a high-stakes policy question. [1]

3. Background & Evolution

• Predecessor: JNNSM → National Solar Mission (NSM) under NAPCC 2008.
• Solar now part of the broader 500 GW non-fossil capacity by 2030 NDC target.

5. Multi-Dimensional Analysis

Economic

• Solar PLI investment of ₹48,120 crore has generated 38,500 jobs by mid-2025; expansion to ingots (upstream) could deepen the domestic value chain. [2]
• India currently imports ~70–80% of solar cells and wafers from China; PLI for ingots targets this import-substitution gap. [4]
• VGF for energy storage would lower the cost of Battery Energy Storage Systems (BESS), making solar dispatchable and reducing grid integration costs.
• Solar sector contributes to fiscal consolidation through avoided fossil fuel imports (India's crude import bill ~$100 bn/year).

Environmental

• 10,203 MW of PM-KUSUM capacity avoids significant diesel use: earlier data showed 143 million litres diesel avoided per year even at lower installed base. [2]
• Solar energy directly displaces coal-fired generation, reducing CO₂ emissions; India's NDC target — net zero by 2070 and 50% non-fossil power by 2030.
• Large-scale solar land use raises concerns of land-use change and habitat disruption (especially in arid/semi-arid zones).

Administrative / Federal

• PM-KUSUM implementation is state-dependent (DISCOMs and state nodal agencies); slow state uptake is a chronic bottleneck.
• VGF for storage requires coordination between MNRE (solar) and MoP (grid/storage); inter-ministerial alignment is a perennial challenge.
• ALMM compliance has periodically restricted project timelines due to limited domestic module supply.

Scientific / Technological

• Ingots are upstream in the solar PV value chain: Polysilicon → Ingot → Wafer → Cell → Module; PLI currently covers modules and cells but not ingots/wafers — the demand targets this gap. [4]
• Energy storage (BESS, pumped hydro) is essential to address solar's intermittency; VGF would de-risk early-stage storage projects.
• India's solar irradiation (~4–7 kWh/m²/day across most regions) gives natural comparative advantage.

Geopolitical / Strategic

• China dominates the solar PV supply chain (~80% of global module production); indigenisation via PLI is a supply-chain de-risking strategy with strategic dimensions akin to semiconductor PLI.
• Solar exports can support India's green trade credentials under emerging Carbon Border Adjustment Mechanism (CBAM) regimes of the EU.

Social

• PM-KUSUM directly benefits farmers by reducing electricity/diesel costs for irrigation pumps; 9.42 lakh standalone pumps installed. [2]
• PM Surya Ghar targets residential consumers, especially low-income households, through free electricity up to 300 units/month. [3]
• Solar manufacturing jobs tend to be semi-skilled, offering livelihood opportunities in tier-2/3 geographies where factories are located.

8. Mains Relevance

GS Paper: Primarily GS-III (Indian Economy — Infrastructure, Energy; Government Budgeting; Science & Technology — indigenisation) Also touches GS-II (Government Schemes, Welfare).

Syllabus headings:

• Infrastructure: Energy — renewable energy, storage, grid integration
• Government Budgeting — PLI, VGF, subsidy rationalisation
• Science & Technology — indigenisation, manufacturing ecosystem

Plausible Mains Questions:

1. "India's solar sector has grown rapidly, yet remains import-dependent at the upstream end of the value chain. Critically examine the role of the PLI scheme and the budget measures needed to build a fully indigenous solar manufacturing ecosystem." (GS-III)
2. "Discuss how Viability Gap Funding (VGF) for energy storage can transform India's solar energy landscape. What are the fiscal and governance challenges in its implementation?" (GS-III)
3. "PM-KUSUM has been hailed as a scheme that can simultaneously address farmer distress and clean energy goals. Evaluate its performance and suggest measures to accelerate uptake." (GS-II/III)

10. Common Errors / Trap Areas

1. Ministry confusion: Solar schemes (PLI, PM-KUSUM, PM Surya Ghar) are implemented by MNRE, not the Ministry of Power (MoP) — though grid/storage involves MoP too.
2. PLI coverage error: Current PLI covers modules and cells — NOT ingots or wafers. The Jan 2026 budget demand is specifically for extending PLI upstream to ingots; do not conflate with existing PLI.
3. PM-KUSUM components: Three components serve different purposes — Component A (decentralised plants/feeders), B (standalone pumps), C (grid-connected pump solarisation) — they are frequently mixed up.
4. Capacity figure trap: "Second-largest installed capacity" refers to solar's position in India's power mix (second after thermal), NOT India's global ranking (third globally after China and USA).
5. VGF ≠ Subsidy: Viability Gap Funding is a one-time capital grant to make commercially unviable but socially/strategically desirable projects viable — distinct from ongoing subsidies or PLI incentives. Examiners test this definitional precision.
