Tata Power commissions India’s largest natural ester-filled power transformer in Mumbai

The company aims to achieve increased transformation capacity with reduced environmental footprint.

Tata Power, one of the largest integrated companies in India, has announced the commissioning of India’s largest natural ester-filled 110/33/22 kV, 125 MVA power transformer in the Mumbai transmission network at the BKC receiving station in active collaboration with Hitachi ABB Power Grids and Cargill. 

The natural esters used in these transformers have a high fire point of 350 degree Celsius and eliminate the risk of fire. The fluid made from a carbon-neutral renewable resource is biodegradable, non-toxic and non-hazardous in soil and water. This fluid allows designing the transformer with increased capacity and reduced carbon footprint, making it an ideal solution for congested cities like Mumbai as opposed to conventional mineral oil-filled transformers.
