Hitachi Energy, a global technology leader in electrification, and Adani Energy Solutions Ltd. (AESL), India’s largest private sector power transmission and distribution company, have successfully commissioned one of the world’s largest High-Voltage Direct Current (HVDC) city centre infeed in Mumbai, increasing power supply coming from outside the city by 50%.

Injecting up to 1,000 Megawatts (MW) of reliable, secure, and clean power directly into one of the world’s most densely populated megacities, the new HVDC link delivers a step-change in Mumbai’s energy resilience. The Kudus-Aarey connection significantly strengthens the city’s transmission infrastructure, supporting the daily needs of more than 20 million people.

Powered by Hitachi Energy’s Voltage Source Converter (VSC) HVDC technology, the link delivers precise, fast control of power flow, improved voltage stability, and enhanced grid reliability in a city where space is scarce.

The aarey converter station upgrade marks the city’s most significant grid modernization in nearly 25 years, boosting the grid capacity from 250 to 1,000 megawatts (MW) and directly reinforcing the city’s energy stability and resilience thus ensuring energy security.

Commenting on the new installation, Kandarp Patel, CEO, Adani Energy Solutions Ltd., said, “The HVDC city centre infeed is a critical enabler of the Mumbai Climate Action Plan, strengthening the city’s ability to integrate renewable energy and build a more resilient, future-ready grid. By expanding access to clean power, this project supports the city’s decarbonization goals and ensures that homes, businesses, transport systems, and digital infrastructure have the reliable, low-carbon electricity they need to grow.”

Delivering this milestone project in the heart of a busy megacity demanded exceptional execution capability.
