Overview
- Adani Electricity Mumbai Infrastructure, which announced commissioning on Tuesday, began operating a 1,000 MW high-voltage direct current link between Kudus and Aarey to feed Mumbai’s grid.
- The corridor runs 30 km on overhead lines and 50 km underground, and it includes what the company calls the world’s first compact HVDC substation designed for tight urban sites.
- Conceived after the October 2020 Mumbai blackout, the project is meant to bring more power into Mumbai and the wider MMR from outside the city, including renewable energy, to cut outage risk.
- The system uses Voltage Source Converter HVDC, a setup that can steer power flows quickly, support voltage during swings, reduce long-distance losses, and restart sections of the grid without outside supply.
- Reports describe the Kudus–Aarey link as among the largest urban HVDC infeeds, and partners highlight it as a model for dense cities that need more capacity without large new surface footprints.
