Adani Energy Solutions Ltd, through its subsidiary Adani Electricity Mumbai Infrastructure Ltd (AEMIL), has commissioned a 1,000 MW high-voltage direct current (HVDC) transmission link between Kudus and Aarey, aimed at strengthening power infrastructure in Mumbai and the Mumbai Metropolitan Region (MMR).
Enhancing urban grid resilience
The project, comprising a 30-km overhead line and a 50-km underground corridor, has been designed to operate within the constraints of a densely populated urban environment. It also features the world’s first compact HVDC substation.
Conceived after the October 2020 Mumbai blackout, the project reflects efforts to enhance grid reliability and prevent large-scale disruptions.
Enabling renewable integration
The Kudus–Aarey link allows Mumbai to draw higher volumes of electricity from outside the city, including renewable energy generated in other regions.
While the city is already connected to the national grid, the HVDC system improves efficiency and control of power flows, supporting higher capacity transmission and facilitating integration of clean energy sources.
Reducing dependence on local generation
The additional 1,000 MW capacity is expected to reduce reliance on in-city power generation, ease network congestion and improve overall system resilience.
For the energy-intensive MMR, this marks a shift towards a more distributed and flexible power sourcing model.
Advanced HVDC technology
The project deploys Voltage Source Converter (VSC)-based HVDC technology, enabling faster and more precise control of electricity flows, improved voltage stability and enhanced reliability.
Key features include dynamic voltage support, lower transmission losses and black-start capability, allowing restoration of power without external supply during outages.
Strategic infrastructure push
The Kudus–Aarey transmission link is among the largest urban HVDC infeeds globally and is expected to significantly increase the share of external power sourcing for Mumbai.
Adani Energy Solutions Ltd, CEO, Kandarp Patel, said: “With the commissioning of the Aarey–Kudus transmission line, Mumbai now has a modern power corridor capable of integrating large-scale renewable energy with high reliability. The project enhances grid stability, decongests existing networks and strengthens the city’s energy security.”
Supporting future demand
The project aligns with the company’s broader strategy to build modern transmission infrastructure to support rising urban demand and India’s renewable energy transition.
As cities expand and energy consumption rises, such infrastructure will be critical to ensuring reliable, sustainable and efficient power supply.
