CEA asks manufacturers how ready they are to supply new transmission tower technologies
Details due: 5 November 2026
CEA has asked manufacturers to report on the development, manufacturing capacity and cost of compact transmission structures that need less right of way. It says a proposal to require these technologies on suitable corridors of upcoming inter-state transmission (ISTS) projects is under active consideration.
Why it matters. It is the first step towards making right-of-way-saving tower designs mandatory on new ISTS lines, so suppliers that can show capacity now are better placed.
What changes
- Covers 400 kV and 765 kV pole structures (double- and four-circuit), 765 kV multi-circuit towers and insulated cross arms at 400 kV and 765 kV.
- Also covers lattice towers from 66 kV to 765 kV, including coastal-stretch designs with a higher importance factor.
- Manufacturers are asked for design validation and type-test status, reference standards and commercial readiness timelines.
- Also asked for annual and monthly production capacity, steel and raw-material sourcing, and indicative costs by structure type.
- Replies go by email to CEA's PSE&TD Division by 5 November 2026.
Who is affected
