In a historic move for the Indian power and manufacturing industries, Proterial India, a subsidiary of the Japanese company Proterial Private Limited, has announced that it will construct the first amorphous electrical steel plant in India. The new plant, to be constructed in Sri City, Andhra Pradesh, will be established at an investment of ₹1,350 crore (approximately $148 million) and is expected to help increase the energy efficiency of India’s power sector.
What Is Amorphous Electrical Steel and Why It Matters
Amorphous electrical steel is a high-performance alloy employed in the production of transformer cores on account of its non-crystalline or ‘glass-like’ atomic structure. This unique property enables it to suppress magnetic core (no-load) losses significantly, as opposed to the conventional grain-oriented electrical steel used in most transformers.
As per industry estimates, transformers employing amorphous steel can reduce core losses by as much as 20-30% relative to traditional materials. This is a major step forward for India, which still loses billions of units of electricity every year due to distribution and transmission losses.
In a country with ambitious plans for energy transition, growing electricity demand, and the need to decarbonize the power system, improving the efficiency of distribution transformers is a major area of opportunity.
Alignment of Strategy with National Policies
The investment made by Proterial India is highly aligned with the flagship initiatives of the Indian government, including Make in India and the Production Linked Incentive (PLI) Scheme for Specialty Steel. These policies are aimed at encouraging the manufacturing sector in the country, reducing imports, and improving the supply chain in the high-technology materials industry.
The PLI scheme, especially the latest version of it (also known as PLI 1.2 for Specialty Steel), provides incentives for the production of advanced and high-quality steel, including electrical and specialty types such as amorphous metal alloys. In this scheme, firms are provided incentives based on incremental production over a period of time.
By establishing a production facility in the country, Proterial India can easily take advantage of this scheme and help the Indian government in its efforts to enhance technology-driven manufacturing.
Local Partnerships and Economic Impact
The new plant will be set up through a partnership arrangement, which will see the involvement of Shirdi Sai Electricals, a well-established transformer manufacturer in India for many years. Shirdi Sai Electricals is expected to bring supply chain linkage to the new plant.
According to local authorities and industry players, the new project is expected to create over 500 direct employment opportunities in Andhra Pradesh, apart from the indirect employment opportunities in the logistics and supply chain functions.
Setting up the new plant in Sri City, a major industrial destination in the state, is also part of Andhra Pradesh’s efforts to attract foreign direct investment and develop its industrial infrastructure.
Market Context and Future Outlook
Presently, the Indian power market is the third-largest in the world, and the demand is growing at a rapid pace due to urbanization, industrialization, and the installation of renewable energy sources. The demand for transformers is directly linked to the expansion of the power grid, rural electrification projects, and the reduction of transmission and distribution losses.
However, while traditional electrical steel has traditionally been the preferred choice for transformer production, the use of amorphous alloys is an attractive option for enhancing efficiency, especially in the case of distribution transformers, which contribute to the largest share of power losses in the network.
Proterial is already producing amorphous metal materials in plants outside of India, such as Japan and the United States, and has been catering to the Indian market for the last two decades. The new plant will therefore represent a change in focus towards local production and supply chains.
Globally, the demand for energy-efficient transformer materials is also increasing due to the growing trend of electrification and sustainability.
Conclusion
On the whole, Proterial India’s ₹1,350 crore investment in the first amorphous electrical steel plant in the country is a highly significant move for the power industry as well as the specialty steel industry. The project will help the country produce a high-efficiency transformer core material that has been import-dependent to a large extent till now. The use of amorphous electrical steel, which has core losses that are much lower than those of conventional materials, may help reduce the transmission and distribution losses in the long run, which have been a structural issue in the Indian power sector.
The project is also in line with the Make in India initiative and the Production Linked Incentive Scheme for specialty steel. This will help the government’s efforts to promote the production of advanced materials in the country and reduce imports. With the growing demand for electricity and the development of the power infrastructure, the production of energy-efficient transformer materials in the country is expected to make the power sector more efficient and sustainable.
