Delhi's 200-unit zero bill & 50% subsidy — built into this calculator
Delhi's scheme works in two layers: use up to 200 units and your bill is ₹0 (zero bill), and 201–400 units get 50% off the energy charge capped at ₹800/month. This calculator applies both layers automatically — untick "Apply state subsidy" to see the full DERC tariff without the scheme, and compare exactly how much the subsidy is saving you.
