ℹ️ TNEB Tariff Overview (Domestic LT1)
🆓 Free Unit SchemeMonthly ≤100 units or Bi-monthly ≤200 units = ₹0 bill. Government subsidy covers the entire consumption.
🧮 Slab SystemOnce consumption exceeds the free limit, slab rates apply from unit 1. Higher slabs attract higher per-unit rates.
🔌 Fixed ChargesSingle Phase: ₹60/month. Three Phase: ₹120/month. Applied only when consumption exceeds the free unit threshold.
🏢 Commercial (LT2)No free unit benefit. Higher slab rates apply from unit 1. Fixed charges regardless of consumption.
📅 Bi-MonthlyReadings every two months. Free threshold doubles (200 units) and all slabs double compared to monthly billing.
⚠️ Other ChargesElectricity Duty (ED) and Fuel Surcharge Adjustment (FSA) may be added by TNEB. This tool shows base tariff estimates only.
⚠️ Tariff rates are approximate based on publicly available TNEB and state DISCOM data. Actual bills may include surcharges, fuel adjustment charges, and other levies. Always verify with your official EB bill or visit your state utility's website. Rates are subject to revision by state electricity regulatory commissions.
