India Sees 1.3 Mn Transformer Failures Each Year: Report

19 Nov 2025 CW Team

India records nearly 1.3 million transformer failures every year, highlighting deep concerns over product quality, insufficient testing and inconsistent compliance with standards, according to a recent assessment by the Central Electricity Authority (CEA). The failures are occurring largely in the distribution segment, which accounts for the vast majority of transformers deployed in the power system.

The report notes that many transformers in the market fail to meet the relevant Bureau of Indian Standards requirements, while inadequate quality checks during procurement and installation continue to aggravate the issue. Ageing infrastructure, overloading, poor maintenance and sub-standard raw materials have also contributed to the high rate of breakdowns.

Officials pointed out that transformer failures ultimately translate into service disruptions, increased technical losses, higher operating costs for discoms and inconvenience for consumers. With India’s growing electricity demand, the problem is expected to worsen unless systematic improvements are made.

The CEA has recommended stricter vendor evaluation, mandatory testing before installation, enhanced surveillance of manufacturing facilities and stronger enforcement of technical standards. It also emphasised the need for utilities to adopt better load management practices, improve maintenance protocols and modernise ageing equipment to ensure grid reliability.
