What the Delhi rules say

Charging at home. The tariff order says that charging your own EV at home uses the tariff of your home. The text: “Tariff applicable for charging of batteries of E-Rickshaw / E-Vehicle at premises other than at Charging Stations meant for the purpose shall be the same as applicable for the relevant category of connection at such prem…” (DERC Tariff Order FY 2021-22 (BRPL), Tariff Schedule clause 10(b), p.357 (also para 5.35(b), p.344)).

A separate EV connection. We did not find a rule in the order that gives a home its own EV connection. The EV rate in the order is for charging stations.

Free units and subsidies. EV units can take you past a scheme limit. Check Electricity subsidy.

How we work it out

  • We price your bill twice: with your present units, and with the EV units added. The difference is the cost of the EV.
  • EV units = km × energy use per km, plus the charging loss.
  • The energy use comes from the maker’s battery size and certified range (IDC for scooters, MIDC or ARAI for cars). These ranges are tests, so real use is higher.
  • The 10% charging loss is our assumption. You can change it.
  • Petrol cost = km ÷ mileage × price. The mileage is the maker’s claimed figure.
