Mumbai Strengthens Grid With Kudus-Aarey HVDC Corridor
Built using 320 kV Voltage Source Converter (VSC) HVDC technology, the corridor spans approximately 80 kilometres and combines overhead transmission lines with extensive underground cabling through densely populated urban zones. The HVDC arrangement gives precise control of power flow and improved voltage stability, while reducing transmission losses compared with legacy alternating current links. These technical features are intended to improve grid reliability for a high?demand metropolitan network.
City officials report that electricity demand is projected to exceed 4,500 MW in the near term, driven by rapid urban growth, commercial expansion and increasing electric vehicle adoption. The Kudus–Aarey link is scheduled to become operational by March 2026 and is designed to help meet rising demand while reducing dependence on fossil fuel?based generation. Its commissioning follows the Kharghar–Vikhroli transmission line, which in 2023 added another 1,000 MW to Mumbai’s grid, creating a more resilient backbone for energy security.
The project was awarded to AESL under the Tariff?Based Competitive Bidding mechanism, with REC Power Development & Consultancy Ltd. serving as bid process coordinator. Industry specialists say the corridor will play a central role in integrating additional renewable energy into Mumbai’s supply mix and in supporting long?term sustainability targets. The installation is expected to contribute to improved reliability and to lower system losses as the city transitions towards cleaner sources.
