TNEB's tariff jumps dramatically at certain thresholds:
| Bimonthly Units | What Happens |
|---|---|
| ≤200 | 🎉 ₹0 bill! (100% free under govt scheme) |
| 201-500 | ₹4.70/unit (only for units above 200) |
| 501+ | ₹4.95-12.15/unit (ALL units charged, higher rates) |
Key insight: If you're at 510 units, dropping just 11 units saves you ₹1,000+ because you move to the lower slab!
