Tata Power carries a substantial portion of bulk power requirement of Mumbai

Tata Power carries a substantial portion of the bulk power requirement of Mumbai. The company’s transmission network comprises approximately 1,100 circuit kilometre of 220-KV/110-KV lines and 20 receiving stations spread across Mumbai.
Power carried by the Tata Power transmission system is utilised by all the four distribution companies operating in Mumbai. Tata Power has transmission schemes approved by the MERC, including installation of a 220-KV transmission line from Kalwa to Salsette, a 220-KV Trombay Dharavi Salsette transmission line, a 145-KV GIS (gas insulated switchgear) at Bandra Kurla Complex, a 145KV GIS at HDIL, Kurla; a 220-KV GIS at Mahalaxmi, a 75-MVA transformer with a 33-KV GIS at Parel, and replacement of a 22-KV bus section at Dharavi.
An islanding system is in place in the network of Mumbai, which isolates it from blackouts caused by faults in national grid. The transmission system is the link between the generating stations and the distribution companies for transmitting power from the generating stations and also is the corridor for bringing in power from outside Mumbai.
Speaking on this, S Padmanabhan, ED – Operations, Tata Power, stated, “Tata Power has a robust, reliable transmission and distribution network in Mumbai. Today Tata Power is a major supplier to retail and bulk consumers of electricity including railways, refineries and industrial/commercial complexes.”
