					</table><p>Tata Consulting Engineers (<a href="https://www.tataconsultingengineers.com/" target="_blank" rel="noopener">TCE</a>), in collaboration with <a href="https://enline.energy/" target="_blank" rel="noopener">Enline</a> and <a href="https://www.gridpulse.com/" target="_blank" rel="noopener">Gridpulse</a>, has commissioned a 400 kV dynamic line rating (DLR) project for Power Grid Corporation of India (<a href="https://www.powergrid.in/en" target="_blank" rel="noopener">PGCIL</a>) on the Madurai–Tuticorin transmission line in Tamil Nadu.</p>
<p>The project employs a real-time, artificial intelligence (AI)-driven approach to improve renewable energy integration, optimize existing grid assets, and enhance operational reliability.</p>
<p>TCE delivered what is claimed as India’s first 400 kV DLR project on a 95 km double-circuit transmission line. The project used DLR sensors placed on critical spans of the Madurai–Tuticorin line to collect real-time weather and line data.</p>
<p>The installation was carried out using hotline methods to avoid power interruptions and adhered to safety and regulatory standards.</p>
<p>The project’s AI-powered platform provided 168-hour forecasting capabilities, offering grid operators advanced warning of potential overloads and weather-related challenges. The DLR deployment is part of PGCIL’s effort to digitize grid operations and accommodate the growing share of renewable energy in Southern India. The Madurai-Tuticorin line plays a key role in evacuating wind power from Tamil Nadu’s coastal and inland wind zones, which frequently experience high generation during cool, windy conditions that favor higher line ampacity.</p>
<p><strong>Digital Technology for Smarter Grids</strong></p>
<p>DLR is recognized in the National Electricity Plan (NEP) 2024 as a critical digital technology for enabling energy transition, improving grid reliability, and optimizing transmission assets.</p>
<p>Unlike traditional static line rating (SLR), which operates on conservative assumptions based on worst-case weather conditions, DLR continuously recalculates a transmission line’s actual current-carrying capacity in real time using weather and operational data. This approach ensures safe, efficient power transfer while unlocking previously untapped capacity.</p>
<p>DLR systems use sensors and satellite data to monitor line conditions, including ambient temperature, wind speed and direction, solar radiation, conductor temperature, and sag.</p>
<p>The information is processed through AI and predictive analytics to adjust line ratings dynamically every few minutes. This allows operators to increase usable transmission capacity by 30%–50% without constructing new infrastructure, significantly improving efficiency and reducing congestion in renewable-rich regions.</p>
<p><strong>Technology Implementation</strong></p>
<p>The system integrates data from meteorological satellites, ground-based sensors, and trusted weather providers with advanced AI algorithms to model conductor cooling behavior and forecast real-time capacity.</p>
<p>Sensor arrays installed on the transmission line measured conductor temperature, sag, mechanical tension, and vibration.</p>
<p>This data was cross-validated with weather inputs to ensure accuracy and reliability. Enline’s hybrid AI model maintained functionality even during sensor or data feed failures by relying on weather-based estimates.</p>
<p>The platform also incorporated a digital twin architecture, creating a virtual replica of the transmission line to simulate and predict performance under various conditions, such as changes in temperature or wind speed.</p>
<p>The real-time dashboards provided operators with a detailed view of line performance, including temperature, sag, and available headroom, enabling immediate operational decisions.</p>
<p><strong>Benefits and Operational Impact</strong></p>
<p>According to TCE, the implementation of DLR on the 400 kV Madurai–Tuticorin line has resulted in measurable operational improvements. The system increased the line’s utilization by up to 25% during favorable weather conditions, enabling more efficient power evacuation from nearby wind farms.</p>
<p>This has directly contributed to reducing renewable energy curtailment, improving transmission reliability, and enhancing overall system stability.</p>
<p>DLR offers significant capital efficiency by deferring the need for new transmission infrastructure. Traditional high-voltage corridor construction can take 5–10 years and involves high costs, regulatory approvals, and land acquisition challenges.</p>
<p>In comparison, the cost of DLR deployment is estimated to be less than 5% of constructing new transmission lines with equivalent capacity. By optimizing existing infrastructure, utilities can redirect capital toward digital modernization and other grid enhancement projects.</p>
<p>The technology enables operators to make informed decisions about load management and maintenance scheduling, thereby reducing the risk of outages and equipment failures.</p>
<p>The Ministry of Power <a href="https://www.mercomindia.com/india-to-expand-power-transmission-network-to-meet-458-gw-demand-by-2032" target="_blank" rel="noopener">targeted</a> expanding India’s power transmission network to 648,000 circuit kilometers (ckm) in 2032 from 485,000 ckm in 2024. The plan is to meet a peak electricity demand of 458 GW by 2032. This plan will help meet the increasing electricity demand and facilitate the integration of renewable energy and green hydrogen into the grid.</p>
<p>The Central Electricity Authority has <a href="https://www.mercomindia.com/cea-guidelines-propose-weather-stations-in-renewable-energy-projects" target="_blank" rel="noopener">proposed</a> the installation of one automatic weather station for each renewable energy project with a capacity of 50 MW. The proposal addresses the need for real-time weather measurement to optimize renewable energy generation, given that solar and wind generation are weather-dependent.</p>
