Voltage upshift (765kV)
What it is
Moving transmission to higher voltage classes - 400 kV to 765 kV AC and beyond - because losses fall and carrying capacity rises sharply with voltage. A single 765 kV line carries several times the power of a 400 kV line on a comparable corridor
Over 18 GVA of transformation capacity was added in the first two months of FY27, led by the 765 kV class
Impact on industries
- Raises equipment value per project - 765 kV transformers, reactors and isolators command far higher realisation than lower-voltage equivalents
- Fewer corridors carry the same power, which directly eases the right-of-way constraint that delays transmission build
- Qualification at higher voltage classes is demanding and slow, so the supplier set narrows to a handful with proven type-tested designs
- It is a capability threshold rather than a market: a manufacturer either has 765 kV qualification or is excluded from the fastest-growing segment
