The 500-Unit Cliff: Why Tier 2 Hurts

The biggest single jump in TANGEDCO's domestic structure is not between slabs — it is between the two tiers. Cross 500 units bi-monthly and the subsidised free quota drops from 200 units to just 100 units. You also unlock the steep upper slabs (₹8.40 → ₹11.55 per unit).

Tier 1 · 500 units 200 free + 200 × ₹4.70 + 100 × ₹6.30 = ₹1,570 energy charge
Tier 2 · 600 units 100 free + 300 × ₹4.70 + 100 × ₹6.30 + 100 × ₹8.40 = ₹2,880 energy charge

100 extra units added ₹1,310 to the bill — an effective rate of ₹13.10 per unit for the extra consumption (because both the lost subsidy and the new top slab hit at once).

This is precisely where a small solar system delivers outsized returns: even a 1 kW system generating 120–140 units bi-monthly can push you back under the 500-unit threshold, restoring the 200-unit subsidy and shaving off the ₹8.40 slab entirely.
