This isn't discretionary spending—it's the essential infrastructure cost of integrating 470 GW of renewable capacity into the national grid. Every watt of that power needs wires, transformers, substations, and transmission lines before it can reach consumers. At the center of this transformation stands Power Grid Corporation of India, the country's principal electric power transmission company, owning and operating 90% of India's interstate and inter-regional electric power transmission system.
The math is straightforward but staggering. India's installed renewable energy capacity stood at 226 GW as of June 2025, nearly three times the 76 GW recorded in 2014. Over the next decade, the country is expected to add another 470 GW of solar and wind energy capacity. This creates a direct proportional relationship between renewable capacity addition and transmission infrastructure needs. The National Electricity Transmission Plan to 2032 aims to add 190,000 circuit km of transmission lines and 1,270 GVA of transformation capacity to support this expansion.
The geographic dispersion of renewable projects is driving this infrastructure requirement. Solar and wind farms are increasingly located far from major consumption centers—in Rajasthan's deserts, Gujarat's coasts, and even Ladakh's high-altitude regions. This distance creates a fundamental challenge: how to move massive amounts of electricity efficiently over thousands of kilometers. The answer lies in High-Voltage Direct Current (HVDC) transmission systems.
HVDC technology is becoming critical for Power Grid Corporation's transmission network because it offers lower transmission losses compared to conventional AC lines over long distances. A single HVDC line can carry 6,000 MW—enough to power entire metro cities like Mumbai or Hyderabad. As renewable projects move farther from consumption centers, efficient long-distance transmission becomes more important. India's HVDC market is expected to grow from $15 billion in 2025 to $31 billion by 2035.
Power Grid Corporation currently operates 18 HVDC stations with 800kV and 500kV systems. The company has 22 HVDC schemes at various stages of planning and bidding, with combined capacity of approximately 127 GW. These include domestic projects like Barmer-II, Ramgarh-II/III, Bhadla-IV/VI, and cross-border initiatives under the "One Sun, One World, One Grid" vision, including India-Sri Lanka and India-UAE links.

Power Grid Corporation has demonstrated remarkable execution capabilities. In FY26, the company achieved actual capex of Rs 39,967 crore, significantly exceeding its revised target.
This was achieved through accelerated execution, record-time project commissioning (the Bhadla substation was completed in just 8 months), and technology adoption including AI-based defect detection and drone-based patrolling. Transcripts +1
The planned capex of Rs 1.08 lakh crore between FY26 and FY28 is expected to translate into sustained revenue growth and margin expansion.
TBCB projects are expected to achieve EBITDA margins of 85-87%, equivalent to RTM margins, while targeting IRR of 10-12%. The company maintains operational availability of 99.85%, among the best globally, with Asset Performance Management Systems expected to reduce operations costs by approximately 10%. Transcripts +2
The estimated business pipeline of Rs 3.06 lakh crore through FY32 provides strong long-term earnings visibility due to structural policy-driven demand. This pipeline comprises approximately Rs 2,70,000 crore in inter-state transmission, with the balance spread across intra-state transmission systems and other businesses including solar generation, smart metering, and data centers. The company maintains approximately Rs 1,54,680 crore of works in hand, providing near-term revenue visibility while the broader pipeline ensures sustained activity through FY32. Transcripts +1
This visibility is anchored in India's ambitious energy transition targets, including a $10 trillion economy by 2032, clean energy commitments exceeding 600 GW by 2032, and Green Hydrogen production targets. The National Electricity Plan for transmission envisions spending approximately Rs 10 lakh crore on transmission systems, providing a robust multi-year demand framework. Transcripts +1
New demand centers are creating additional transmission infrastructure requirements. AI and data centre clusters are creating 1 GW+ point loads, requiring robust transmission infrastructure. Green hydrogen projects are expected to drive ~71 GW demand uplift by 2032, with projects already identified at Kakinada, Vizag, and Tuticorin valued at ~Rs 13,103 crore. Railway electrification and electric vehicles are contributing to increased power demand that requires transmission infrastructure support. InvestorPresentations +1
The causal relationship between industrial expansion and transmission infrastructure requirements is fundamental.
With energy requirements expected to grow at approximately 5.06% CAGR, peak demand is projected to increase from 249.85 GW (as of September 2024) to 388 GW by March 2032. Transcripts +2
Power Grid Corporation faces significant challenges from execution delays, land acquisition issues, raw material price volatility, and HVDC project timing. However, the company has developed comprehensive mitigation strategies. The Government of India has revised guidelines with significantly increased compensation for land acquisition—30% for rural areas, 45% for semi-urban areas, and 60% for urban areas/metro cities. Management indicates these measures are showing results on the ground. Transcripts +1
For raw material price volatility, the company leverages regulatory provisions to protect margins. Transmission line contracts are awarded on firm prices, protecting against metal price variations. For substations, Price Variation clauses are incorporated during bidding. The Transmission Service Agreements include critical protections for force majeure and change in law situations, allowing the company to claim extra tariff from CERC for unexpected costs.

The company has established itself as the pioneer of ±800 kV HVDC technology in India, with demonstrated leadership across multiple high-voltage transmission technologies including 765 kV and 1200 kV systems. The company currently operates 11 HVDC projects encompassing both back-to-back and bi-pole configurations, with approximately 101 GW of inter-regional capacity out of India's total 120 GW inter-regional capacity—representing approximately 84% of the country's total.

HVDC technology plays a crucial role in minimizing transmission losses through technical innovations. The company optimizes various parameters during the design stage to reduce line losses. The adoption of higher voltage systems like ±800kV HVDC and 765kV double circuit transmission lines enables considerable reduction in right-of-way requirement per MW of power transfer, resulting in lower overall system losses. HVDC technology also significantly contributes to grid stability through advanced capabilities including independent control of active power and reactive power, black start capability, and system resilience under various operating conditions.
