| Fluorescent tubes | 8 | 40 | 1900-2300 |
| Ceiling fan | 3 | 45 | 1900-0700 |
| Refrigerator | 1 | 800 | 0000-2400 |
| Washing Machine | 1 | 500 | 2000-2100 |
Given Tariff A for residential customers is:
| 1 - 200 kWh | 0.218 RM/kWh |
| 201 - 300 kWh | 0.334 RM/kWh |
| 301 – 600 kWh | 0.516 RM/kWh |
| 601 – 900 kWh | 0.546 RM/kWh |
| 901 kWh onwards | 0.571 RM/kWh |
