How Taiwan's Electricity Pricing Works

Taiwan Power Company (Taipower) uses a tiered pricing system for residential electricity. The more you use, the higher the per-unit cost for the excess portion. It works like tax brackets: only the electricity above each threshold gets charged at the higher rate, not your entire bill.

What Costs the Most?

Heating and cooling dominate most electricity bills. A single electric water heater at 4,000W running 2 hours a day uses about 240 kWh per month. An inverter air conditioner at 900W running 8 hours uses around 216 kWh. Meanwhile, a fridge running 24/7 only uses about 94 kWh because its wattage is relatively low. If you want to cut your bill, start with the big hitters.

Summer vs. Non-Summer Rates

Taipower designates June through September as "summer months" with higher rates, but only on the top two tiers (above 700 kWh/month). The first four tiers are identical year-round. So if your household uses under 700 kWh, summer and non-summer bills are essentially the same. The surcharge only kicks in at high usage levels.

Quick Ways to Save

Switch to LED bulbs (10W vs 60W for incandescent). Set your AC to 26-28°C and use a fan for circulation instead of cranking it down to 22°C. Unplug devices you're not using or use power strips with switches — standby power adds up across a whole household. Inverter appliances (AC, fridge) cost more upfront but save significantly over their lifetime.
