en.Wedoany.com Reported - Adani Energy Solutions Ltd (AESL), through its subsidiary Adani Electricity Mumbai Infrastructure Ltd (AEMIL), has commissioned a 1GW High Voltage Direct Current (HVDC) transmission line in Mumbai, India. This project will enhance grid stability and energy security across the Mumbai Metropolitan Region (MMR), reduce reliance on local generation, and lower the risk of power outages.
The new line includes a 30-km overhead section and a 50-km underground corridor, connecting Kudus and Aarey, and is equipped with a compact HVDC substation specifically designed for urban environments. Following the Mumbai blackout in October 2020, this project aims to strengthen grid robustness and reliability, allowing for increased power import from external sources, including renewable energy, thereby improving the flow and capacity of electricity into the city.
By adding 1GW of capacity, the project reduces dependence on generation within the city, enhances grid resilience, and lowers the probability of widespread outages. As part of AESL's strategy, the project is dedicated to developing modern transmission infrastructure to integrate India's growing renewable energy resources into the city's grid. Utilizing Voltage Source Converter (VSC)-based HVDC technology enables more precise power flow control in space-constrained urban settings, improving voltage stability and reliability.
The Kudus-Aarey line is one of the world's larger urban HVDC feeder lines and is expected to increase the proportion of electricity supplied from outside Mumbai, alleviate the load on local generation, and enhance grid stability as MMR's demand grows. AESL CEO Kandarp Patel stated, "With the commissioning of the Aarey-Kudus transmission line, Mumbai now possesses a modern power corridor capable of integrating large-scale renewable energy with high reliability. This is one of the fastest-commissioned HVDC projects, driven by advanced VSC-based HVDC technology."
Patel added, "This project enhances grid stability, alleviates congestion on the existing network, and strengthens the city's energy security. It marks a significant step towards a cleaner, more resilient energy future for Mumbai." In February this year, AESL secured long-term financing from Japanese banks for a 950-km HVDC transmission project in India. This project is designed as a green evacuation corridor with a capacity of 6,000MW, connecting Bhadla in Rajasthan to Fatehpur in Uttar Pradesh.
