Tata Power Delhi Distribution Ltd, a joint venture of Tata Power and Government of Delhi, recently commissioned a 66kV grid substation at Rohini Sector-28 and India’s first 33/11kV grid substation with dry type power transformers at Model Town, in New Delhi. These substations are part of the company’s Distribution Network Automation Programme.
The 66kV grid substation at Rohini Sector-28 will benefit over one lakh existing and new consumers in Sectors 27, 28 & 29, Shahbad Dairy, Delhi College of Engineering and Prahladpur areas. The grid-substation, which has been built at a total cost of Rs.15.5 crore, is unmanned and will be remote operated from TPDDL’s state-of-the-art supervisory controlled and data acquisition centre (SCADA). The substation will further improve the reliability of power supply and felicitate load growth in the above areas.
The 66kV Rohini-28 grid substation has an installed capacity of 50 MVA with two incoming supplies of 66kV and 16 outgoing supplies of 11kV feeders to TPDDL network. It is equipped with state-of-the-art relays and power transformers with nitrogen injection, fire prevention and extinction system for safe and reliable power supply.
Dedicating the grid substation, Delhi Chief Minister Sheila Dikshit said, “The demand for electricity in Delhi is growing with each passing year. Commissioning of the new 66kV Rohini-28 grid substation will go a long way in ensuring reliable power supply in Rohini and surrounding areas.”
“The commissioning of 66kV Rohini-28 grid substation is a reflection of our commitment to N-1 Model of power supply meaning technical problem or overloading at one place should not affect supply in other areas. We are committed to make our network as robust as possible so that it can meet any eventualities. This remote operated grid substation will lead to better reliability of supply. Our consumers can look forward to many more such initiatives of network augmentation in the days to come,” said Praveer Sinha, CEO & Executive Director, Tata Power Delhi Distribution Ltd.
The chief minister also inaugurated a 33/11kV grid substation at Model Town that will benefit over 80,000 customers including those in Azadpur area. It will also feed power supply to several schools in the area.
The grid substation, developed on the green grid design model, is equipped with the dry type power transformers of 20 MVA, used for the first time in India. It also contains nickel-cadmium batteries and LED lights which reduce energy consumption and greenhouse gas emission. The grid is also unmanned and will be remote operated by TPDDL. It has been built at a total cost of Rs.16 crore.
