Adani Electricity Mumbai Infrastructure Ltd. (AEMIL), a subsidiary of Adani Energy Solutions Ltd. (AESL), has commissioned a 1,000 megawatt (MW) high-voltage direct current (HVDC) transmission link between Kudus and Aarey.
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.
Conceived in the aftermath of the October 2020 Mumbai blackout, which exposed vulnerabilities in the city's power supply, the project reflects a broader push to strengthen grid resilience and reliability, according to the company's press release.

At its core, the link enables Mumbai and the MMR to draw more electricity from outside the city, including renewable energy generated in other regions.
While Mumbai is already connected to the national grid, the HVDC link enhances this connectivity by enabling more controlled, efficient, and higher-capacity power flows, particularly for renewable energy integration.
The additional 1,000 MW of capacity helps reduce reliance on in-city generation, improves grid resilience, and lowers the risk of large-scale outages.
"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 release said.
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.
