Tamil Nadu power utilities financial health

Notes

• Tamil Nadu has 78 State Public Sector Undertakings (SPSUs) with approximately 2.55 lakh employees.
• A recent White Paper on public finances projects the accumulated debt of major SPSUs to reach ₹3.18 lakh crore by March 31, 2026.
• Financial distress in SPSUs is attributed to the failure to periodically revise user charges, limiting funds for capital investment and asset maintenance.
• The Tamil Nadu Electricity Board (TNEB), a vertically integrated utility (1957-2010), was restructured into TANGEDCO and the Tamil Nadu Transmission Corporation.
• In 2024, TANGEDCO was further split into the Tamil Nadu Power Generation Corporation Limited (TNPGCL) and the Tamil Nadu Power Distribution Corporation Limited (TNPDCL).
• Renewable energy operations were consolidated into the Tamil Nadu Green Energy Corporation Limited (TNGECL).
• The policy of free electricity for various consumer categories has significantly impacted the fiscal autonomy of power distribution entities.
• Domestic power tariffs saw limited revisions in the last decade, specifically in 2014 and 2022.
• Financial stress in the power sector is exacerbated by high costs of power procurement and material acquisition.
• The gap between the Average Cost of Supply (ACS) and Average Revenue Realised (ARR) has been partially mitigated by state government financial support and union government bailout packages.
