In light of the recent grid outage in the Mumbai metropolitan region, the state government has sanctioned a plan to build an 80 km underground transmission network from Aarey to Kudus, in Palghar district, at an estimated cost of Rs 80 billion.
On October 12, 2020, the entire Mumbai and its adjacent regions suffered a major power blackout due to grid failure which happened because of a technical fault. The government has decided to fast-track the underground high-voltage direct current (HVDC) cables project. The proposed stretch would be built by Adani Electricity Mumbai Limited (AEML) within the next three years. The first-of-its-kind project would provide an additional 1,000 MW of electricity to Mumbai. The HVDC technology has a unique feature of blackstart, which ensures faster restoration of power supply in the event of widespread grid disturbances.
