India is expanding its power infrastructure while domestic CRGO production remains below national requirements. This article examines BIS certification, import availability, domestic capacity expansion, transformer costs and why CRGO requires a specialised policy approach.

Efficient and reliable power distribution depends heavily on the quality of transformer cores, and at the heart of every high‑efficiency transformer lies Cold Rolled Grain Oriented (CRGO) electrical steel. Among all available grades, 0.23 mm CRGO is considered the premium and most widely accepted thickness for modern distribution and power transformers due to its superior magnetic properties and low core losses. In India, where power demand continues to rise and grid efficien
