Impact of PLI Schemes on Domestic Value Addition (DVA): Solar PV, Telecom, and Textiles

The Production Linked Incentive (PLI) Scheme (total outlay ~₹1.97 lakh crore across 14 sectors) was designed to transition India from mere downstream, low-margin assembly to high-value, integrated manufacturing.

The impact of PLI on Domestic Value Addition (DVA) varies significantly across sectors depending on the complexity of upstream supply chains, raw material integration, and global market dynamics.

1. Telecom & Networking Equipment: The Success Story in DVA

The telecom sector has been among the fastest to achieve substantial domestic value addition and import substitution.

• DVA Trajectory: Domestic value addition rose from 15–20% in the pre-PLI era to over 50–60% across targeted product lines (e.g., GPON equipment, 4G/5G radio access network gear, enterprise routers, and switches).

• Key Drivers of Value Addition:

  • Import Substitution: Replaced ~60% of imported networking equipment in domestic telecommunications networks.

  • Indigenous Stack Deployment: Facilitated the manufacturing and deployment of India’s indigenous end-to-end 4G/5G telecom stack.

  • Sub-Assembly Localisation: Transitioned beyond basic surface-mount assembly to domestic production of Printed Circuit Board Assemblies (PCBAs), power modules, and antenna arrays.

• Remaining Gaps: Continued reliance on imported high-end semiconductors, System-on-Chips (SoCs), and specialized optical components.

2. High-Efficiency Solar PV Modules: Scaling the Upstream Ladder

Prior to PLI, India was heavily reliant on imports (primarily from China) for ~85–90% of its solar cells and modules, with domestic manufacturing largely confined to module assembly using imported cells.

• DVA Trajectory:

  • Under PLI Tranche I & II (outlay of ₹24,000 crore), the scheme incentivized fully integrated manufacturing (Polysilicon $\rightarrow$ Ingot/Wafer $\rightarrow$ Solar Cell $\rightarrow$ Module).

  • Domestic value addition for modules assembled with domestic cells is around 35–45%, and approaches 70–80%+ for end-to-end vertically integrated lines.

• Key Drivers of Value Addition:

  • Capacity Creation: Aiming to establish nearly 48–65 GW of integrated domestic manufacturing capacity.

  • Policy Reinforcement: Supported by complementary tariffs (Basic Customs Duty of 40% on modules and 25% on cells) and the Approved List of Models and Manufacturers (ALMM) mandate.

• Remaining Gaps: The capital-intensive upstream stages (polysilicon refining and wafer slicing) face long gestation periods and high power tariffs, keeping domestic cell makers partially reliant on imported wafers in the interim.

3. Textiles & Apparel (MMF & Technical Textiles): The Strategic Shift

India’s traditional textile base is dominated by cotton (where DVA is naturally high), but global trade is ~70% skewed toward Man-Made Fibres (MMF) and Technical Textiles. The ₹10,683 crore PLI scheme was tailored specifically to plug this structural gap.

• DVA Trajectory:

  • Value addition in targeted synthetic lines is estimated at 30–50%, shifting the export mix away from low-value raw cotton yarn toward high-value performance apparel, geotextiles, agrotextiles, and medical textiles.

• Key Drivers of Value Addition:

  • Productivity & Scale: Encouraged large anchor investments in specialized synthetic polymer spinning, fabric weaving, and garment processing.

  • Integration with PM MITRA: Synergized with mega integrated textile parks to bring spinning, dyeing, processing, and garmenting into unified industrial clusters, reducing logistical value leakage.

• Remaining Gaps: Slower initial investment disbursement compared to electronics/telecom due to high minimum turnover thresholds and fragmented MSME supplier networks.

Comparative Summary for Policy & Examination

Dimension	Telecom & Networking	Solar Photovoltaics (PV)	Textiles (MMF & Technical)
Pre-PLI DVA	Low (~15–20%)	Very Low (~10–15% on module assembly)	High in cotton; low in MMF (<25%)
Post-PLI DVA	Moderate–High (~50–60%)	Progressive (~35–45% modules; 70%+ integrated)	Expanding (~30–50% in MMF)
Primary Mechanism	Component & PCBA localisation; 5G rollouts.	Tiered incentives favoring polysilicon-to-module integration.	Incentivizing high-density MMF fabrics & technical textiles.
Critical Bottleneck	Semiconductor/chip design deficit.	High capex and power costs for polysilicon ingots.	MSME fragmentation and global apparel tariff barriers.

Critical Assessment: The "Assembly vs. Deep Manufacturing" Debate

1. The Raghuram Rajan / Arvind Panagariya Critique: Critics argue that early iterations of PLI (especially in electronics and consumer goods) rewarded high gross turnover derived from assembling imported Completely Knocked Down (CKD) kits rather than genuine local value creation.

2. Policy Counter-Interventions: The government has refined guidelines by enforcing minimum domestic value addition thresholds (e.g., in ACC batteries, telecom, and solar) and launching the Electronic Components Manufacturing Scheme (ECMS) to build the tier-2 and tier-3 supplier base domestically.
