  • Over 21,000 ckt. km of line length and over 80,000 MVA of transformer capacity have been added to the country's transmission network in the past 12 months. The line length and transformer capacity have grown at an average annual growth rate of 6.5 per cent and 9.6 percent, respectively, over the past five years.

  • This pace of expansion in the transmission sector must continue in order to ensure that the government's renewable energy and 24x7 Power for All goals are met. Both the generation and distribution sectors are undergoing significant reforms owing to enabling policy and regulatory measures put in place by policymakers and planners. The development of the transmission sector must also move forward to ensure that a strong and reliable backbone grid is ready to support the shift in generation mix and distribution loads.

  • Large-scale capacity addition and connection of millions of new consumers to the grid requires major grid planning, and empowerment of system operators and regulators to ensure effective implementation of relevant policies and regulations.

  • An estimated Rs 2.6 trillion investment is required in the transmission sector to meet the future peak load, which is expected to reach 234 GW by 2021-22. While the majority of the future investments will be spent on the expansion of the physical grid infrastructure, utilities are also expected to invest significant sums in new technologies to make the grid more reliable, resilient, secure and smart.

  • The increasing share of renewable energy in the generation mix is expected to have a considerable impact on the grid. Significant investment is under way not only for the creation of integration and evacuation infrastructure, but also for the establishment of management centres to undertake forecasting and real-time monitoring of renewable energy generation. Ancillary services, which were introduced in May 2016, have already led to an improvement in the frequency profile and in congestion management

  • Over the next four years (by 2021-22), more than 85,000 ckt. km of transmission lines and 230,000 MVA of transformer capacity are expected to be added to the grid. The private sector could play an important role in achieving these targets. The competitive bidding process for interstate projects has resulted in the discovery of low tariffs and faster project execution. Despite its success at the interstate level, only a handful of states (Uttar Pradesh and Jharkhand) have adopted this model. Also, the project pipeline for interstate TCBC projects has been shrinking in recent years, with a current investment outlook of only around Rs 112 billion at both the interstate and intra-state levels.

  • New technologies and designs are being used to address right-of-way issues. These include narrow-based and multi-circuit towers, GIS and EHV XLPE cables. Digital substations are helping improve system efficiency, safety and visibility. Utilities are also adopting various technology and analytics solutions to better manage their transmission assets.

  • Reactive compensation devices are being installed to reduce transmission losses and prevent voltage collapses. For dynamic monitoring of the grid on a real-time basis, PMUs and WAMS are being deployed. With the increasing adoption of smart technologies, the need for cybersecurity has become paramount. To combat the growing instances of cyberattacks, the central government has been taking several initiatives, especially with regard to critical infrastructure.

  • The grid must also be prepared to efficiently manage new demand-supply patterns as large amounts of energy storage capacity come online. Also, the government's e-mobility programme, which aims to increase the share of electric vehicles to 30 per cent by 2030, is expected to alter the load profiles and significantly impact grid operations.

  • The mission of this conference is to discuss the trends, developments, plans and opportunities in the Indian power transmission sector. The conference will highlight some of the new and emerging challenges facing the sector, and the possible solutions and ongoing initiatives to address these. The conference will also showcase relevant technologies and noteworthy projects.
