MUMBAI URJA MARG TRANSMISSION PROJECT

Mumbai Urja Marg is an inter-state transmission system project covering Western Region Strengthening Scheme-XIX (WRSS-XIX) and North Eastern Region Strengthening Scheme-IX (NERSS-IX) spanning across Maharashtra, Gujarat, Assam and Arunachal Pradesh. This is a single project with various sub-elements as conceptualized by the Ministry of Power.

The Package C of Mumbai Urja Marg Transmission project involves setting up of ~100 kms of transmission lines for critical system strengthening in Mumbai Metropolitan Region(MMR). Once operational. the project will have the potential to carry more than ~2000 MW of additional power to Mumbai and Navi Mumbai while also establishing a much needed transmission corridor to enable increased power flow across the state.
Mumbai Urja Marg will be also critical to prevent future blackouts in Mumbai Metropolitan region by decongesting the entire transmission network and providing an ISTS feed for upcoming Vikhroli substation which was cited as the major intervention to avoid future power outages. Not only this, one of the strongest benefits of the Mumbai Urja Marg Project is that it establishes the last mile connectivity of Mumbai with Padgha to bring renewable power to MMR.

With the promise of 24×7, affordable and green power flow across the state, Mumbai Urja Marg is well poised to be a true gamechanger for Maharashtra.

PROJECT ELEMENTS

Mumbai Urja Marg has three elements in Maharashtra with each of them playing a crucial role in transforming the power scenario in the region.

  • 1. 400 kV D/C (quad) Padgha to Kharghar Transmission Line

    This high voltage line will connect Powergrid’s 765kV Substation at Padgha with MSETCL’s 400 kV substation at Khargar. This additional ISTS feed will have the potential to carry ~2000 MW of reliable power to Mumbai Metropolitan region thereby reducing over dependency on the existing Padghe- Kalwa Line which currently is the only corridor bringing power inside the region.

  • 2. 400 kV D/C Padgha to Navi Mumbai LILO Transmission Line

    This line would be instrumental in reviving and energizing PowerGrid’s 400/220KV substation which has been lying idle since 2012. The 400KV LILO will energize the PowerGrid’s Navi Mumbai Substation and will significantly relieve the overloaded Kharghar and Kalwa Substations ensuring reliable power flow for the entire Navi Mumbai region.

  • 3. 220 kV D/C Apta – Taloja LILO Transmission Line

    This line will ensure downstream connectivity by connecting Navi Mumbai substation to Apta -Kalwa/Taloja line at 220 kV level, thereby creating Navi Mumbai -Kalwa, Navi Mumbai – Apta and Navi Mumbai – Taloja line. This will decongest the overloaded Apta-Kalwa-Taloja network, immensely benefitting the industrial and residential units in the region.
