Adani Energy Solutions’ (AESL) subsidiary – Adani Electricity Mumbai Infrastructure (AEMIL) has commissioned a 1,000 megawatt (MW) high-voltage direct current (HVDC) transmission link between Kudus and Aarey in a significant step towards strengthening power infrastructure in Mumbai and the wider Mumbai Metropolitan Region (MMR). 

The project, comprising a 30-kilometre (km) overhead line and a 50-km underground corridor, has been designed to operate within the constraints of a densely built urban environment. It also features the world’s first compact HVDC substation. The development reflects AESL’s broader focus on building modern transmission infrastructure to support India’s growing renewable energy capacity. As demand rises in urban centres, integrating long-distance clean power into city grids is becoming critical to sustaining growth while meeting decarbonisation goals.

The project deployed Voltage Source Converter (VSC)-based HVDC technology. This enables faster and more precise control of power flows, improves voltage stability, and enhances grid reliability, particularly in space-constrained urban environments. It also offers key operational benefits, including dynamic voltage support, reduced transmission losses over long distances, and black-start capability, enabling restoration of power without relying on an external source and allowing quicker recovery in the event of outages.

The Kudus–Aarey link is among the largest urban HVDC infeeds globally and is expected to significantly increase the share of power sourced from outside Mumbai, easing pressure on in-city generation and strengthening grid resilience as demand continues to grow across the MMR.

Adani Energy Solutions (formerly known as Adani Transmission) is the transmission business arm of the Adani Group, one of India’s largest business conglomerates.
