Effective Jan 1, 2014, electricity tariff in Sabah and Labuan FT will be increased by 16.9%, or 5 sen/kWh from 29.52 sen/kWh to 34.52sen/kWh in average, as announced by Energy, Green Technology and Water Minister Datuk Dr Maximus Ongkili yesterday.
But if you use more than 500 kWh a month than your bill actually increases more than 16.9% for domestic users (households).
Lets make a simple calculation. If a family has 2 1-HP (~ 0.8kW power consumption) air con and use them for 10 hours every day. In a month the 2 air con would use 480 kWh. If you include the TV, hot water heater, lights, etc, then you are easily using more than 500 kWh per month. If you have 3 air con then most likely you will be in the top rank of > 1,000 kWh usage. Below I calculated the electricity bill for household usage. You can see the increment for usage > 1,000 kWh is actually almost 25%.
Below is the new and old SESB's tariffs for comparison.
