Tata Power starts up largest natural ester filled transformer

Tata Power, India’s largest integrated company, announced the commissioning of India’s largest natural ester filled 110/33/22 kV, 125 MVA power transformer in the Mumbai Transmission network. The commissioning was achieved at the BKC receiving station in active collaboration with Hitachi ABB Power Grids and Cargill, the supplier of the natural ester transformer oil.

The natural esters used in these transformers have a high fire point (350 degree Celsius) and eliminate the risk of fire. The fluid is made from a carbon neutral renewable resource, is biodegradable, nontoxic 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, the company said.

“We have always been committed towards providing greener and sustainable solutions for our customers while ensuring uninterrupted power supply. We will continue to implement newer technological innovations and aim to reduce the carbon footprint along with improving overall performance,” said Dr. Praveer Sinha, CEO and managing director, Tata Power.

A pioneer in providing reliable and uninterrupted power supply to the city of Mumbai, Tata Power Transmission caters around 70% of Mumbai’s energy. It has a network of about 1,200 circuit transmission lines in and around Mumbai with a transformer capacity of about 10,500 MVA. The company is committed to implement cutting edge solutions to cater to the increasing power demand in the city where space is a constraint.
