TNEB Financial Crisis Threatens Tamil Nadu's USD 1-Trillion Economy Goal
A financial assessment of the Tamil Nadu Electricity Board (TNEB) has revealed that the state-run power utility has suffered severe losses for years due to poor management and corruption. Despite ranking among the best in India for operational and technical efficiency, TNEB's weakened financial state now threatens Tamil Nadu's ambition of becoming a $1-trillion economy.
According to the assessment, the utility's financial instability persists despite having some of the lowest aggregate technical and commercial losses in the country. While the long-delayed unbundling of the erstwhile TNEB marked a starting point for reform, energy experts and industry representatives state that restoring financial sustainability remains a critical challenge.
The growing financial burden on the state is substantial. Subsidies and loss funding for the power sector are projected to account for nearly ₹27,053 crore in 2025-26, representing approximately 35 percent of Tamil Nadu’s revenue deficit. Tariff subsidies alone have climbed from around ₹8,932 crore in 2021-22 to nearly ₹16,951 crore in 2025-26.
One of the key drivers of the financial situation is the state's electricity tariff policy, which automatically adjusts tariffs annually based on the Consumer Price Index or 6 percent, whichever is lower. V Sriram, co-founder and partner at Sammati Consulting and Analytics, stated that this automatic revision reduces the necessity for utilities to file detailed tariff petitions before the regulator, thereby limiting independent scrutiny of costs and operational efficiency.
To address these fiscal pressures, experts have urged the state government to transition from debating the existence of subsidies to better targeting them. The government's decision to restrict the additional 100 units of free electricity to households consuming under 500 units a month is considered a positive step.
Further reforms are being suggested for the agricultural sector, where power remains largely free. M Prasanna Kumar, former CMD of NLC India, recommended separating agricultural, industrial, and residential feeders to improve accounting transparency. Additionally, with the state's peak power demand crossing 20,000MW, Kumar highlighted the need for faster implementation of battery energy storage systems and pumped storage projects to manage renewable energy integration and lower procurement costs.
