Tata Power to install India’s first-of-its-kind underground submersible substation in Mumbai

Tata Power has announced the setting up of an innovative submersible power substation in South Mumbai to augment the power infrastructure in its operational area.

Occupying virtually zero space, this underground substation will be a first-of-its-kind submersible substation installed by any power distribution utility in the country. The substation will have specially designed 22 kV submersible duty three-way ring man unit, 22 kV/433 V 400 kVA transformer with accessories suitable for submerged operations. The installation will be in compliance with Central Electricity Authority’s safety regulations. The sub-station will be installed in the parking area of the Parel Receiving Station and will support power demand load of high-rise infrastructure in the adjoining areas and ensure a continuous and reliable power supply to consumers during exigencies, including floods and storms. Tata Power plans to install 10 such submersible substations by 2025 in its Mumbai license area.
