Reliable power is a prerequisite to Maharashtra’s vision of becoming a trillion-dollar economy. Owing to large scale infrastructure development, the current peak power demand in Mumbai Metropolitan Region is around 4500 MW; partly met through the 1877 MW power generated in Mumbai while the remaining power is catered from outside Mumbai through the current transmission network. A strengthened power transmission system is the need of the hour and Mumbai Urja Marg is one such project that’s committed towards providing critical energy lifeline for Mumbai Metropolitan Region. The inter-state transmission system project envisaged by Ministry of Power, is envisioned with the objective of providing reliable, affordable, and green power for the developing Mumbai Metropolitan Region. Once operational, Mumbai Urja Marg Transmission Project will have the potential to carry more than ~2000 MW of additional power through an inter-state transmission system (ISTS) feed to the region. The project will also strengthen the existing transmission system to address the growing power demands and make it future ready in terms of energy requirement.
