That’s a major milestone for India’s power sector. BHEL’s successful development and testing of the first indigenous 1200 kV Ultra High Voltage AC transformer (333 MVA rating) places India firmly in the league of nations capable of designing and manufacturing such cutting‑edge grid equipment.

The reason it’s called India’s first indigenous 1200 kV Ultra High Voltage AC transformer (333 MVA rating) is because until now such ultra‑high voltage transmission technology was either imported or developed abroad. BHEL’s achievement marks the first time this level of transformer has been designed, engineered, manufactured, and tested entirely within India.

Developed by BHEL’s engineers without foreign technical dependence, showcasing India’s self‑reliance in critical grid infrastructure, the 1200 kV benchmark is the highest AC voltage class in the world, surpassing the 765 kV systems widely used in the USA and the 1000–1100 kV systems in China.

The 333 MVA capacity rating indicates its ability to handle massive power flows, essential for bulk transmission across India’s expanding grid.Global first: While other countries operate UHVAC networks, India’s 1200 kV transformer is unique in being indigenously built and tested to full capacity.

While other countries operate UHVAC networks, India’s 1200 kV transformer is unique in being indigenously built and tested to full capacity. Moreover, it reduces reliance on imports, strengthens Aatmanirbhar Bharat, and positions India as a global leader in ultra‑high voltage transmission.

Why It Matters

Modi Showcases India’s First 700 MWe Nuclear Steam Generator at L&T Hazira

Prime Minister Narendra Modi’s visit to L&T’s Hazira complex showcased India’s indigenous 700 MWe nuclear steam generator, a milestone in self-reliant energy manufacturing. This achievement, supported by NPCIL and complemented by BHEL’s contributions, strengthens India’s nuclear expansion under the Aatmanirbhar Bharat vision.

A nuclear steam generator is basically a giant kettle inside a nuclear power plant — it takes heat from the reactor and turns water into steam that spins turbines to make electricity. It’s one of the most critical parts of the system, but the principle is simple enough for everyday understanding.

Key Highlights of the Visit

• Event: PM Modi visited L&T’s A. M. Naik Heavy Engineering Complex, Hazira (Gujarat) on 5 June 2026.
• Showcased Equipment: A 700 MWe nuclear steam generator manufactured indigenously by L&T for NPCIL.
• Significance: Reinforces India’s ability to design and produce critical nuclear components domestically, reducing reliance on imports.

What is a 700 MWe Steam Generator?

• A steam generator is a giant heat exchanger inside nuclear reactors.
• It transfers heat from the reactor core coolant to water, producing high-pressure steam that drives turbines to generate electricity.
• These generators are designed for India’s 700 MWe Pressurised Heavy Water Reactors (PHWRs).

Role of L&T

• L&T has dispatched seven 700 MWe steam generators ahead of schedule for NPCIL projects.
• Manufactured at Hazira and Vadodara facilities, adhering to stringent safety standards.
• Supports India’s fast-track nuclear programme and PM Modi’s Aatmanirbhar Bharat vision.

Role of BHEL

• BHEL has been a partner in India’s nuclear programme since 1976.
• Recently secured a ₹1,405 crore order to supply 12 steam generators for NPCIL’s 700 MWe PHWR fleet mode programme.
• BHEL’s Trichy plant has already dispatched its 42nd nuclear steam generator for NPCIL’s Rajasthan Atomic Power Project.
• BHEL remains the only Indian company associated with all three stages of India’s nuclear programme.

National Nuclear Expansion

• NPCIL operates 24 reactors (8,780 MW), with 13,100 MW under implementation.
• Indigenous 700 MWe PHWRs are central to India’s target of 100 GW nuclear capacity by 2047.
• Each 700 MWe reactor generates ~5.2 billion units annually, avoiding 4.5 million tonnes of CO₂ emissions.

Comparative Snapshot: L&T vs BHEL in Nuclear Steam Generators

Company	Contribution	Recent Milestone	Facilities
L&T	Manufactures 700 MWe steam generators for NPCIL	7 units dispatched ahead of schedule	Hazira & Vadodara
BHEL	Supplies steam generators, turbine sets, reactor headers	42nd steam generator dispatched (Rajasthan Atomic Project)	Trichy plant

Strategic Importance

• Strengthens energy security by reducing dependence on foreign suppliers.
• Creates skilled jobs and builds advanced engineering expertise.
• Supports India’s clean energy transition and net-zero 2070 goals.

BHEL vs BEL Stocks Performance Overview

Two major engineering and electronics companies listed on the Indian stock market are Bharat Heavy Electricals Limited (BHEL) and Bharat Electronics Limited (BEL), respectively. Both state-owned businesses have become quite important players in India's defense capabilities and infrastructure growth. To help readers make smart choices, this article offers a thorough review of their stock performance, financial situation, and market outlook.

Company Profiles

Bharat Heavy Electricals Limited (BHEL)

Originally established in 1964, BHEL is the biggest manufacturing and engineering company in the energy sector in India. The organization specializes in manufacturing thermal, hydro, nuclear, solar, and thermal power plants. Having a presence in more than 88 countries, BHEL is dedicated to furthering India's self-reliance goals using major technological and research and development (R&D) investments. Its product offerings include power transformers, thyristor valves, and gas-insulated switchgear.

Bharat Electronics Limited (BEL)

Originally established under the Ministry of Defence in 1954, BEL is dedicated to meeting the specific electronic requirements of the Indian Armed Forces. It has evolved over the years into civilian products while still focusing on defense technologies mostly. BEL provides radar systems, missile systems, electronic warfare technology, and communication systems. With nine manufacturing facilities all throughout India, the company has developed into a multi-product conglomerate.

Stock Performance Comparison

Depending on their operational domains and market conditions, BHEL and BEL have seen different stock performances.

Market Capitalization

• BHEL: Approximately ₹77,893.76 Cr
• BEL: Approximately ₹2,05,441.33 Cr

BEL's market capitalization reflects investor confidence and strong demand for its products, so it much exceeds that of BHEL.

Financial Performance Highlights

In terms of profitability, BHEL has encountered challenges. For instance, its Price-to- Earnings (P/E) ratio is rather high at 174.77 but its Return on Capital Employed (ROCE) is only 3.18%. This suggests that, given growing running expenses, investors are skeptical of BHEL's earning potential. Current trends suggest that the BHEL share price has displayed swings inside a range of ₹219.66 to ₹226.35 as investors keep a close eye on its performance.

With a ROCE of 33.71% and a P/E ratio of 45.26 BEL has a far better financial profile. These numbers imply that BEL is making more profit than BHEL using its capital, thereby suggesting effective utilization of it. The company's strong foundations and constant demand for its defense products have shown more consistency in the BEL share price.

Recent Financial Results

In recent quarters:

In September 2024, BHEL recorded net sales of ₹6,584.10 Cr. However, expenses exceeded sales by ₹6,369.19 Cr.

In contrast, BEL maintained profitability despite increased expenditures, with net sales of ₹4,604.90 Cr and expenses of ₹3,316.14 Cr during the same period.
