Mumbai Urja Marg involves providing inter-state transmission system (ISTS) feed to Navi Mumbai. The project consists of three elements as given below:
| S.No | Elements of Package | Length of the line | Regions covered | Planned Date of Commission | Impact |
|---|---|---|---|---|---|
| 1 | Padgha-Kharghar 400 Kv D/C (quad) | 70 KMS | Panvel (Raigad), Ambernath, Kalyan, Thane and Bhiwandi tehsils from Thane district | December 2023 | Potentially 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 | Line in Line Out (LILO) of Padgha- Navi Mumbai (Ghatkopar) 400 Kv S/C line | 19 KMS | Panvel (Raigad) and Ambernath (Thane) | December 2023 | Energize PowerGrid’s 400/220KV substation which has been lying idle since 2012 and will significantly relieve the overloaded Kharghar and Kalwa Substations ensuring reliable power flow for the entire Navi Mumbai region. |
| 3 | Line in Line Out (LILO) of Apta -Kalwa- Taloja 220 Kv D/C | 1.2 KMS | Panvel (Raigad) | December 2022 | Ensure downstream connectivity and will decongest the overloaded Apta-Kalwa-Taloja network, immensely benefitting the industrial and residential units in the region. |
