India, Maharashtra, Mumbai: Hitachi Energy and Adani Energy Solutions Ltd. have successfully commissioned a major HVDC city centre infeed in Mumbai, serving more than 20 million people and significantly strengthening the city’s electricity network.
The project increases the power supply imported from outside the city by 50 %, delivering up to 1,000 MW of reliable, secure, and cleaner electricity directly into one of the world’s most densely populated urban areas. It provides a major upgrade to Mumbai’s transmission system, supporting daily demand and improving overall grid resilience.
The Kudus–Aarey HVDC link, powered by Hitachi Energy’s Voltage Source Converter (VSC) technology, enables fast and precise power flow control, improved voltage stability, and enhanced reliability. It marks a major modernisation step for the city’s grid, increasing capacity from 250 MW to 1,000 MW and supporting energy security and stability.
The project also plays an important role in supporting Mumbai’s Climate Action Plan by enabling greater renewable energy integration and contributing to the city’s decarbonisation goals. It helps ensure a stable supply of low-carbon electricity for homes, businesses, transport systems, and digital infrastructure.
Due to Mumbai’s dense urban environment, the project required a compact converter station design and the use of around 50 km of underground HVDC cables. This approach helped overcome space constraints and released valuable urban land, demonstrating how advanced engineering can support large-scale infrastructure in megacities.
The HVDC link draws power from outside the city, including renewable energy sources from Maharashtra and other regions connected to India’s national grid. It is seen as a scalable model for other cities facing rising electricity demand and limited space for new infrastructure.
