The Indian power grid is undergoing a transformational change. Large-scale integration of renewable energy and the need to cater to new demand loads and provide reliable electricity are motivating transmission utilities to redesign their grid strategies. The coming years will require utilities to focus more on grid optimisation, reliability, resilience, and flexibility in order to improve access to cheaper power and enable the integration of renewable energy.

To prevent upcoming generation capacity from getting stranded and to ensure timely power supply to intended consumers, the transmission grid must expand in tandem with planned generation. Innovations in the design and construction of lines, towers and substations are being undertaken for faster execution.

Issues pertaining to RoW, high cost of land, forest conservation and visual impact are being addressed through the use of new tower designs (narrow base, multicircuit, monopoles) and advanced conductor technologies (HTLS and HPCs). Utilities are opting for reconductoring and uprating of lines to enhance the capacity of the existing transmission corridors. In densely populated and urban areas where land availability is an issue, underground cables (XLPE cables) are being preferred.

Transformer and switchgear technologies have evolved over the years. Energy-efficient and environment-friendly transformers are being deployed to reduce the environmental footprint. GIS and hybrid switchgear are being preferred over the regular air- or oil-insulated switchgear due to advantages such as small size, high safety index, and lower maintenance. Smart transformers and switchgear equipped with multiple IEDs or control systems are now entering the market. A breakthrough in switchgear technology is the use of a new eco-friendly insulation mixture to address the environmental concerns of SF6 in switchgear.

Utilities are working towards improving power quality and enhancing grid optimisation, especially as more renewable energy comes online. Solutions such as FACTS and capacitor banks are being deployed to ensure grid stability and reliability.

Technologies such as remote control, automation systems and smart applications allow for open and real-time operation of the grid system. Since a robust and reliable communication system forms the foundation of such an automated grid system, utilities are deploying technologies such as optic fibre, VSAT and IEC 104 protocol on digital PLCC for data transfer

Digitalisation is another fast emerging trend, driven by the need to introduce efficiency in grid operations, and operations and maintenance. With benefits such as increased flexibility and availability, reduced cost, and lower risk and environmental impact, an uptake in the deployment of digital substations is seen across utilities

With advancements in transmission equipment technology, design and construction methods have also evolved. Technologies like helicopter stringing, LiDAR, sky crane and UAVs or drones are being used in the planning, designing and construction of overhead transmission networks..

Utilities are undertaking active asset management and maintenance to maximise asset life, prevent outages, and optimise maintenance effectiveness and efficiency. The digital and robotic solutions being deployed for this include geospatial data for asset management, GIS-based tracking of assets, remote monitoring and control equipment, and smart field force management.

The mission of the conference is to highlight the most promising technologies and viable solutions to deliver a reliable and secure transmission grid infrastructure. It will present the experience with these technologies so far, and the expected trends. It will also showcase successful projects and best practices.
