  • The global electricity transmission sector is expected to witness investments of over USD 600 billion over the next few years, mainly due to the thrust provided by recent policy measures and the right regulatory initiatives.

  • New designs, solutions and construction techniques for power evacuation infrastructure (transmission lines, towers and substations) are thus becoming a growing area of interest for utilities and the industry.
  • .
  • Tower designs that address RoW issues, reduce visual impact, help in faster execution and provide ease of installation have entered the transmission market. Tower designs that are catering to the emerging requirements include monopoles, delta configuration towers and chainette towers.

  • Advancements have also taken place in tower profiles, foundation designs and materials used for tower construction. Tube profiles are being used in place of angle profiles as they help in faster erection, reduce the steel requirement, and attract lower wind loads. Pre-cast and grillage foundations, which are factory-made solutions, as well as monopole foundations, which are compact, lightweight and visually more aesthetic, are solutions that are being considered to provide customised solutions and reduce construction time. Pultruded fibre-reinforced polymer (P-FRP) towers and cross-arms are also being used as replacements for ageing wood poles in remote/extremely humid locations.

  • Advanced conductor and cable technologies are also playing an important role in reducing the RoW requirement in addition to providing greater efficiency, reliability and ease of design. Some of the emerging conductor designs are high temperature low sag (HTLS) and high performance superconductors. XLPE cables and gasinsulated lines (GILs) offer attractive alternatives for undergrounding lines in urbanised areas. The solutions being used for uprating and re-conductoring include STACIR conductors and gap-type conductors.

  • Meanwhile, transformer technologies too have evolved considerably over the years, from conventional oil-filled transformers to dry-type transformers and further to advanced smart transformers. The next generation of transformer technology, including smart transformers, comes with remote monitoring of a wide range of grid parameters as well as transformer parameters.

  • Technological advancements have resulted in making switchgear that is more compact, reliable and environment friendly. Gas-insulated switchgear (GIS) and hybrid switchgear help lower the RoW requirement and reduce the cost of construction and maintenance. Another emerging trend in the switchgear segment is the use of intelligent switchgear, which allows real-time flow of information.

  • Automated substations with intelligent electronic devices (IEDs) are gaining prominence, allowing utilities to secure real-time and enterprise-wide information, and enabling them to improve the overall reliability of the system. There is also an increased emphasis on upgrading substation automation systems to IEC 61850- compliant open standards.

  • With the ever increasing load growth, there is an increasing focus on deploying solutions for regulating power flows, increasing the network transfer capacity and reducing short circuit levels. Some of solutions available to address these issues are series capacitors, FACTS devices, phase-shifting transformers and fault current limiters.

  • With advancements in transmission equipment technology, design and construction methods have also evolved. Light detection and ranging (LIDAR) surveys, global positioning systems (GPS), building information modelling (BIM) techniques and power line systems-computer aided design and drafting (PLS-CADD) modelling techniques are being used for the design of lines and substations. Further, mechanised techniques such as helicopters, drones and cranes for line stringing, monitoring and repair are becoming increasingly popular.

  • Asset management based on advanced analytics is helping utilities prevent failures, identify critical assets and avoid premature asset replacements. New technologies, especially devices for remotely monitoring and controlling equipment, are being deployed to make grid operations more efficient.
  • The mission of this conference is to highlight the latest innovations and most promising and relevant technologies in transmission towers, conductors and substations. It will also discuss the new and emerging requirements of the transmission segment as well as showcase successful projects and best practices.
