Noida and Greater Noida are set to receive 250 new transformers under the Revamped Distribution Sector Scheme (RDSS), as the electricity department begins strengthening Gautam Buddh Nagar’s network ahead of next summer. The new 250 kVA and 400 kVA transformers are intended to reduce overloading and lower the risk of transformer failures in residential and other high-demand areas.
The installation is being carried out under the scheme supported by the Centre and the Uttar Pradesh government. The electricity department has set a target of completing the work by March 2027, according to officials quoted in the report. Surveys are being conducted to identify locations where transformers are operating under high load, after which additional units will be installed.
Officials said the new transformers will distribute electricity demand across more units. Once commissioned, the transformers are expected to operate at no more than 50% load, reducing the pressure on existing equipment. The department plans to prioritise locations where overloading has been recorded or where demand is expected to rise during the summer.
Gautam Buddh Nagar currently has more than 24,000 transformers ranging from 10 kVA to 650 kVA, the report said. The largest number are 25 kVA transformers installed for tube-well connections. The network serves consumers across Noida, Greater Noida and other parts of the district, where rising summer demand has previously placed additional stress on local distribution infrastructure.
Electricity department officials said transformer-related problems become more likely when demand rises during hot weather. A transformer’s normal temperature may be around 40 to 50 degrees Celsius, while summer conditions can push it to 80 to 90 degrees Celsius. This can lead to oil leakage, equipment failure or, in some cases, a blast, resulting in local outages and unscheduled power cuts.
The department has therefore started the work before the next summer season rather than waiting for peak demand. The stated objective is to reduce failures by lowering the load on existing transformers and improving the reliability of supply for consumers. The installation schedule will depend on the survey findings and the identification of overloaded locations.
The new transformers will also be tracked through a colour-coding system. Newly installed units will be marked blue and green. If a transformer fails for the first time, it will be painted yellow; a second failure will result in orange marking, while a third failure will be indicated by red. The system is intended to help officials identify equipment with a repeated history of failure.
Vivek Kumar Patel, superintending engineer, technical, of the electricity department, said work was being undertaken continuously to improve the district’s power infrastructure. He said 250 new transformers of 250 kVA and 400 kVA capacity would be installed at a cost of several crores, adding that the work was expected to significantly reduce the risk of transformer burnouts. The department has set March 2027 as the completion target.
