What the Puducherry rules say
Charging at home. The tariff order says that charging your own EV at home uses the tariff of your home. The text: “(ii) In case the consumer uses the electricity supply for charging his own electric vehicle at his premises, the tariff applicable shall be as per the category of such premises.” (JERC Order: True-up FY 2023-24, APR FY 2024-25, ARR 4th MYT FY 2025-26 to FY 2029-30, Electricity Department of Puducherry (24-09-2025), printed p.259).
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.
Time of day. For homes with a smart meter. 09–17 h 80%, 17–00 h 125%. (JERC Order: True-up FY 2023-24, APR FY 2024-25, ARR 4th MYT FY 2025-26 to FY 2029-30, Electricity Department of Puducherry (24-09-2025).) We apply it to the EV units only.
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.
