India’s power industry is entering a period of tight supply and growing uncertainty as the nation continues to grapple with a deepening shortage of Cold Rolled Grain Oriented (CRGO) steel, the critical transformer steel used in power distribution, electrical motors, and renewable energy infrastructure.

CRGO—engineered for low core loss and high magnetic permeability—remains irreplaceable in modern transformer core design. Yet India’s domestic output has not kept pace with the rapid expansion of its energy systems.

A December 2024 report from the Global Trade Research Initiative (GTRI) highlights a widening gap: local production contributes only 10–12% of total demand, leaving manufacturers heavily dependent on imported grain-oriented electrical steel. As the country accelerates grid modernization and renewable energy deployment, this supply imbalance is becoming a structural challenge.

A Market Growing Faster Than Supply

Domestic Availability Remains Limited

In FY 2023–24, India produced approximately 50,000 mt of CRGO steel—far below the required volume for transformers, motors, and distribution equipment.

Demand Driven by Grid Expansion

Total CRGO demand for the year was estimated at 400,000 mt, driven by:

• New transmission and distribution projects

• Rapid electrification across industrial and rural regions

• Transformer upgrades supporting renewable energy integration

Heavy Reliance on Imports

India imported 239,000 mt of CRGO from China, Japan, Russia, and South Korea. Despite these imports, the domestic market still faces a 30% shortfall.

This shortage poses risks for large-scale renewable integration, where high-performance transformer steel is indispensable.

Certification Delays Intensify the Supply Gap

One of the biggest disruptions in India’s CRGO supply chain comes from BIS (Bureau of Indian Standards) licensing delays.
Many global manufacturers saw their certifications renewed far later than expected—especially from Japan, South Korea, and China—resulting in:

• Interrupted shipment cycles

• Longer procurement lead times

• Delayed transformer manufacturing schedules

For a market where timely access to transformer core steel determines the pace of energy projects, these delays create major operational uncertainty.

Why Transformer Steel Demand Will Keep Rising

1. National Power Grid Expansion

India’s roadmap to 2030 includes integrating 500 GW of renewable energy. Each solar park, wind farm, and substation requires transformers built with high-grade CRGO steel.

2. New Energy Efficiency Requirements

Starting January 2025, the Bureau of Energy Efficiency (BEE) will mandate star-rated distribution transformers. This significantly increases demand for:

• High-permeability CRGO steel

• Low-loss transformer core materials

• Premium electrical steel suitable for efficient grid operation

As energy efficiency standards tighten, transformer manufacturers will require higher-grade steel—not just more steel.

Technical and Structural Barriers Facing India’s CRGO Market

1. Insufficient Domestic Manufacturing Know-How

India has limited capacity to produce advanced CRGO grades needed for high-efficiency transformers. Most domestic mills cannot yet manufacture ultra-low-loss or domain-refined grades.

2. Restrictive Approved Grade List

The BIS-approved CRGO catalogue is far narrower than global offerings, limiting access to:

• High-performance transformer steel grades

• Next-generation electrical steel used in renewable energy systems

3. High Lead Times for Imported Steel

Customs procedures, logistics delays, and certification bottlenecks push import lead times longer, affecting transformer OEMs with tight delivery commitments.

4. Export Prioritization by Domestic Producers

Some local manufacturers export part of their output for higher-margin markets, further reducing the steel available for Indian transformer factories.

Strategies India Must Implement to Secure Transformer Steel Supply

1. Upgrade Domestic Production Infrastructure

India must invest in modern EAF-based CRGO production lines and advanced annealing technologies to reduce its reliance on imports.

2. Reform BIS Certification Workflow

A streamlined certification framework will allow faster approval of foreign suppliers while maintaining quality standards.

3. Broaden the Import Network

India should diversify beyond traditional CRGO sources to reduce supply concentration risks.

4. Promote Recycling and New Material Research

Strengthening domestic scrap recycling and exploring alternative magnetic materials could gradually ease pressure on CRGO supply.

Conclusion: India Must Act Now to Avoid Long-Term Transformer Steel Bottlenecks

India’s CRGO shortage is no longer a temporary supply inconvenience—it is becoming a structural constraint for the country’s power sector. Without decisive action to expand production, secure diversified import channels, and modernize certification processes, critical power and renewable projects may face delays and cost escalations.

Ensuring stable access to transformer-grade CRGO steel will be essential for India to meet its 2030 energy targets and maintain momentum in its transition toward a modern, efficient national grid.
