The State will not be burdened with any tariff revision, including the annual revision of 3.57% this year, said Tamil Nadu Electricity Minister R. Nirmalkumar on Thursday (June 25, 2026).

Mr. Nirmalkumar, while presenting a White Paper on the status of the Tamil Nadu electricity department, said the Tamil Nadu Power Distribution Corporation Limited (TNPDCL), Tamil Nadu Power Generation Corporation Limited (TNPGCL), Tamil Nadu Green Energy Corporation Limited (TNGECL), and TANTRANSCO have sustained heavy losses, with the total debt of the four corporations standing at ₹2.47 lakh crore. The erstwhile Tamil Nadu Electricity Board (TNEB), which was bifurcated into TANGEDCO and TANTRANSCO in 2010, was further restructured into four corporations in 2024. The report highlighted deficiencies in electricity infrastructure, power generation, and manpower, and stressed the need to replace ageing transmission and distribution infrastructure.
The Electricity Minister said the White Paper was presented to show that the tariff revision implemented by the previous government in 2022, which led to a spike in electricity charges for all categories of consumers, benefited neither the electricity department nor the consumers, as substantial expenditure was incurred on power purchase agreements.
