Adani Energy Solutions Commissions 1,000 MW Kudus-Aarey HVDC Link
Adani Electricity Mumbai Infrastructure, a subsidiary of Adani Energy Solutions, has commissioned a 1,000 MW HVDC transmission link between Kudus and Aarey to strengthen Mumbai’s grid reliability and enable higher renewable power integration.

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 built urban environment. It also features the world’s first compact HVDC substation, claimed the company.
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.
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, stated the company.
For the MMR, one of India’s most energy-intensive urban clusters, this marks a shift in how electricity is delivered. 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.
Commenting on the development, Kandarp Patel, CEO, Adani Energy Solutions, 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. It is one of the fastest HVDC projects ever commissioned, which is powered by advanced VSC-based HVDC technology. The project enhances grid stability, decongests existing networks and strengthens the city’s energy security. This marks a significant step towards a cleaner, more resilient energy future for Mumbai.”
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, stated the company.
