Tariff Orders TNERC

About Dataset

These documents from the Tamil Nadu Electricity Regulatory Commission (TNERC) establish the electricity tariffs and charges for the state of Tamil Nadu for the financial year 2023-24, effective from July 1, 2023. The primary tariff order sets the retail supply rates for all consumer categories, including domestic, industrial, commercial, and agricultural users. It applies a 2.18% increase based on the Consumer Price Index, with a 6% cap, as approved in a previous multi-year tariff framework. A significant revision is made for Electric Vehicle (EV) charging stations, aligning tariffs with central government guidelines by ensuring rates do not exceed the Average Cost of Supply and reducing demand charges by 75% as per state policy. A separate order revises all non-tariff related miscellaneous charges—such as connection fees, meter rent, testing charges, reconnection costs, and security deposits—by the same 2.18% inflation adjustment. Another document specifies the scheduling and system operation charges payable to the State Load Despatch Centre (SLDC) for grid management services during FY 2023-24. These orders are governed by the foundational TNERC (Terms and Conditions for Determination of Tariff) Regulations, 2005. This regulatory framework outlines the principles for tariff setting, including cost computation, return on equity, depreciation, and operational norms for generation, transmission, and distribution, ensuring that tariffs progressively reflect the cost of supply while safeguarding consumer interests.
