Understanding TNEB Tariff Structure
What is TNEB Tariff?
Tamil Nadu Electricity Board (TNEB) tariff is the rate structure used to calculate electricity bills for consumers in Tamil Nadu. The tariff follows a slab-based system where different rates apply to different consumption ranges, encouraging energy conservation.
TNEB tariffs are categorized into domestic, commercial, and industrial connections, each with specific rate structures. The tariff includes energy charges, fixed charges, electricity duty, and applicable subsidies or surcharges.
The current tariff structure promotes energy efficiency by charging higher rates for higher consumption levels, while providing subsidies for lower consumption households to ensure affordability.
