Hitachi Energy and Indian transmission operator Adani Energy Solutions have commissioned a new high-voltage direct current (HVDC) link in Mumbai, India, increasing the city’s external power supply by 50%.

The transmission link between Kudus in north-eastern Maharashtra and the Aarey converter station in northern Mumbai offers electricity capacity of up to 1,000 MW into one of the world’s most densely populated megacities, supporting a network serving more than 20 million people.

 

Conceived after the October 2020 blackout, which exposed vulnerabilities in the city’s power supply, the project improves Mumbai’s ability to import electricity from across Maharashtra and renewable-rich regions of India’s national grid.

 

Designed for a dense urban environment, the link includes a 30 km overhead line and a 50 km underground corridor, helping free around 2 km2 of urban land.

 

Powered by Hitachi Energy’s voltage source converter technology, the converter station upgrade represents Mumbai’s most significant grid modernisation in nearly 25 years, increasing capacity from 250 MW to 1,000 MW.
