Electrical steel for India’s electricity evolution
energy concepts | innovation | Smart energy | Sustainability and climate protection | In Nashik, India, in 2018 thyssenkrupp began producing a true milestone product for the country’s rapidly growing electricity requirements: grain-oriented electrical steel.
In western India near the Godavari River, which is seen as holy by Hindus, thyssenkrupp took a new production plant into operation in April 2018. 160 kilometers northeast of Mumbai the company is India’s first ever manufacturer of a material aimed at making the huge country fit for the future: grain-oriented electrical steel.
Innovative, loss-free, grain-oriented
Grain-oriented electrical steel is a frequently underestimated material and plays a key role in supplying power: the soft magnetic steel can always be found wherever electrical energy is efficiently converted, transported and used such as in distribution and power transformers. There’s a reason for this: When electricity needs to be transported over great distances it must be converted to a higher voltage than that at which it is generated. The current during transportation is around one thousand times higher than that in domestic power sockets. To make the electricity usable again in households and industry it must then be converted a second time.
A cornerstone of India’s efficient energy future since March 2018: thyssenkrupp‘s new production plant for grain-oriented electrical steel in Nashik.
The special composition of thyssenkrupp’s electrical steel ensures that virtually no power is lost during conversion as the iron-silicon alloy concentrates and strengthens the magnetic flux. While the magnetic properties of the non-oriented variant allow the electricity to flow in all directions, making it particularly valuable in ensuring the efficiency of rotating machinery such as electric motors, grain-oriented electrical steel allows the current to flow exclusively in one particular direction and the opposite direction – perfect for the electricity network.
Electrical steel can be found wherever energy efficiency is needed.
Electrical steel: a trump card for the energy transition
Thanks to its capabilities, the material is becoming a key factor for the success of the transition to renewables. The fluctuating demand for power already requires management and balancing, and the increased use of renewable energies will make this task even more complex in the future. So domestic production of grain-oriented electrical steel is a milestone for the steel market in India.
The demand for electricity on the subcontinent is growing constantly, not only because the population continues to grow moderately but steadily, but also because the living standards of Indians is becoming more demanding year after year. Although the per capita consumption is currently still one third of the global average, total consumption in India is expected to reach 4,000 terawatt hours by 2030. To put this into perspective: In 2015, around 600 terawatt hours of electricity passed through the meters of high-tech-country Germany. All in all, it’s a massive infrastructural task for Indian politics and industry. thyssenkrupp’s grain-oriented electrical steel is to play a decisive role in the solution – and make India’s energy network more efficient and efficient than ever before. A large number of customer orders already exist. Two thirds of them come from India.
