TGTransco leading transmission line modernisation with HTLS conductors

The Telangana state utility has pioneered unmanned substations and remarkably reduced transmission losses to just 2.05%.

- 

TGTransco, Telangana's transmission utility, is in charge of modernising power infrastructure through strategic planning, advanced technologies, and efficient execution. With a strong focus on enhancing grid capacity and reliability, the utility has adopted High-Temperature Low-Sag (HTLS) conductors, multi-circuit towers and underground gas-insulated substations. It has also pioneered unmanned substations, reduced transmission losses to just 2.05% and ensured seamless integration of renewable energy. A notable achievement is upgrading a 220kV line, which now carries up to 400 MW, twice the typical limit. This accomplishment has earned national recognition. TGTransco's approach revolves around able leadership, timely technology adoption, decentralisation and long-term strategic planning.

Jagath Reddy, Director of the PSU, shares more insights in an exclusive interview with EPR. Let us hear more from him.

How is Telangana modernising its transmission infrastructure to meet future power demands?

As we move forward in time, our transmission infrastructure is also evolving with technological advancements. We are focusing on enhancing transmission capacity by replacing conventional conductors with state-of-the-art High-Temperature Low-Sag (HTLS) conductors, which enable us to double the power transfer capability. Additionally, we are constructing transmission lines with multi-circuit towers and monopoles wherever right-of-way (RoW) constraints exist, ensuring optimal land usage and minimal disruption. We are adopting the latest technologies and setting benchmarks in network development, becoming a reference point for several other utilities across India. Many state utilities visit our substations to learn about the advanced technologies we have implemented.
