⚠️ Slab traps in Delhi: 201 and 401 units
Delhi's subsidy is generous but has two hard edges. Up to 200 units the government pays your whole bill. At 201 units that stops, and you get 50% off (up to ₹800). With a 2 kW connection and 10% FPPAS, 200 units cost you ₹0 but 201 units cost ₹418.
The second edge is at 400 units: 400 units cost ₹1,200 after the ₹800 subsidy, while 401 units cost ₹2,008 because the subsidy ends completely — ₹808 for one extra unit. If you are close to 200 or 400 units, a few units saved in the last days before the reading make a big difference.
Worked example — 300 units, 2 kW, with subsidy
| Units 1–200 × ₹3.00 | ₹600.00 |
| Units 201–300 × ₹4.50 | ₹450.00 |
| Fixed charge | ₹40.00 |
| Deficit surcharge @ 8% | ₹87.20 |
| Pension trust surcharge @ 7% | ₹76.30 |
| Fuel surcharge (FPPAS) @ 10% | ₹109.00 |
| Electricity tax @ 5% | ₹52.50 |
| Delhi government subsidy | −₹707.50 |
| Total | ₹707.50 |
Assumes a 30-day bill; the subsidy limits are pro-rated for other billing periods. Arrears and late-payment charges are not included.
