Statcon Energiaa Pvt. Ltd. (SEPL), one of India’s leading manufacturers of mission-critical power electronics, has been awarded an order by L&T Electrolysers Limited to supply high-power rectifiers for India’s largest green hydrogen plant – the 10 kTPA Green Hydrogen Project being set up at the Indian Oil Corporation Limited (IOCL) Panipat Refinery & Petrochemical Complex, Haryana.
India’s largest green hydrogen plant – a 10 kTPA facility at IOCL’s Panipat Refinery & Petrochemical Complex – is being built by L&T Energy GreenTech, targeted for commissioning by December 2027. It is the first concrete step in IOCL’s ambition to generate 350 kTPA of green hydrogen by 2030 – a landmark for India’s energy transition and for Make in India in clean energy.
The national importance of this initiative was recognised at the highest level when Hon’ble Prime Minister Shri Narendra Modi visited L&T’s Hazira facility, reaffirming India’s commitment to building a self-reliant green hydrogen ecosystem and advancing the National Green Hydrogen Mission.
What distinguishes this project is an end-to-end Make in India supply chain at its core.
L&T Electrolysers Limited is manufacturing high-pressure alkaline electrolysers in 4 MW modular blocks at its advanced facility in Hazira, Gujarat – making this India’s first large-scale green hydrogen project powered by indigenously manufactured electrolysers, a meaningful step towards Aatmanirbhar Bharat and a reflection of L&T’s commitment to strengthening India’s self-reliant green hydrogen ecosystem.
Statcon Energiaa is supplying the 4 MW rectifier blocks that power those electrolysers – also manufactured entirely in India.
The rectifiers will use the powerful IGBT Chopper-based technology, backed by AEG Power Solutions, Germany. Build for high efficiency, round-the-clock performance, these are developed under Statcon Energiaa’s exclusive licensing and supply agreement with AEG Power Solutions GmbH, Germany – a global leader in industrial power conversion with over a century of engineering heritage. Under this agreement, Statcon Energiaa designs, assembles, commissions, and services these rectifiers on Indian soil, using AEG PS’s proven core components – IGBT modules, thyristors, and more – while engineering them specifically for India’s operating conditions.
Key technical highlights of the rectifiers:
- Topology: Thyristor-based 12-Pulse bridge with IGBT chopper
- Cooling: Liquid-cooled for sustained 24×7 operation
- Input: Engineered for high power quality from variable renewable (solar) energy sources – addressing one of the most demanding challenges in renewable-powered electrolysis
- Output: Low-ripple DC output, critical for efficient and stable alkaline electrolysis
- Block size: 4 MW per unit – mirroring L&T’s 4 MW electrolyser block in a truly modular, indigenous architecture
The pairing is deliberate: L&T manufactures the 4 MW electrolyser block, and Statcon Energiaa the 4 MW rectifier block that powers it – both made in India, for one of the country’s most significant clean energy projects.
Powering the electrolysers at the heart of a project of this national importance carries a profound responsibility. These rectifiers must operate continuously, drawing from intermittent solar or other renewable energy to feed electrolyser stacks that demand uncompromising power quality. Living up to that responsibility meant engineering to the most exacting technical requirements:
- Input line power quality: Handling variability from renewable source without disrupting electrolyser performance
- Output stability and low DC ripple: Essential for efficient, consistent hydrogen generation
- Efficiency: Sustained thermal and electrical performance under continuous load
- Harmonic distortion control: Protecting electrolyser stacks and maximising operational longevity
- Proven reliability: Track record in mission-critical deployments
Statcon Energiaa’s rectifiers deliver on every one of these requirements – ensuring the electrolysers powering IOCL’s landmark green hydrogen project run reliably, around the clock.
Statcon Energiaa’s selection for this project is the result of over 37 years of manufacturing excellence in power electronics, a deeply held philosophy of indigenous engineering, and a growing track record in green hydrogen specifically.
The company previously supplied rectifiers for the NTPC Green Hydrogen Mobility Project in Leh – one of India’s first hydrogen fuel cell bus deployments, operating at 3,600 metres above sea level in temperatures ranging from -14°C to +20°C. Statcon Energiaa engineered its rectifiers to perform in ambient conditions as extreme as -25°C to +45°C – a demonstration of what genuine Made-in-India engineering looks like. Apart from this, the company has supplied for 4 other Green Hydrogen Projects in India which are currently in operation.
Statcon Energiaa’s commitment to Make in India is a founding principle. From building India’s first MW-class rectifier for the Indian Navy, to manufacturing defence-grade power systems serving Naval Dockyards in Visakhapatnam and Mumbai for over 13 years, to developing India’s first 100% domestically designed on-grid solar inverter – the company has consistently chosen to engineer from the ground up, rather than import and rebadge. With over 30,000 installations across more than 25 countries, Statcon Energiaa carries this philosophy into every sector it serves.
L&T’s IOCL Panipat order award is entirely in line with that vision: leveraging world-class technology – AEG Power Solutions’ proven rectifier platform – but manufacturing it in India, for India, and standing behind it with full end-to-end lifecycle support.
Anil Dhar, Marketing Director, Statcon Energiaa Pvt. Ltd., said, “This order represents exactly what Statcon Energiaa has always stood for – delivering world-class technology, made in India, for India’s most critical infrastructure. L&T Electrolysers’ qualification process is among the most demanding we have encountered. Meeting every parameter – power quality, efficiency, harmonic performance, output stability, and reliability – reflects the maturity our technology and manufacturing have reached against rigorous global standards. What makes this especially meaningful is the symmetry of the project: L&T is building the 4 MW electrolyser block; we are building the 4 MW rectifier block that powers it. Both are Indian-made. For a company that has believed in Make in India since before it was a policy, this is a proud moment. India is not just consuming green hydrogen infrastructure – it is building it. For Statcon Energiaa, the opportunity to power a project of such national significance is both a privilege and a responsibility it is proud to carry.”
