Question 1

How much does electricity cost in Vietnam on the EVN tariff?

Accepted Answer

State utility EVN uses a 6-tier progressive residential tariff: from 1,893 ₫/kWh in tier 1 (up to 50 kWh) to 3,302 ₫/kWh in tier 6 (over 401 kWh), plus 8% VAT. The effective average at 300–500 kWh is about 2,700–3,000 ₫ per kWh.

Question 2

Why do landlords charge 4,000–5,000 dong per kWh?

Accepted Answer

Many landlords set a flat 3,500–4,500 ₫/kWh rate in the lease. It is legal if written in the contract: the difference covers taxes, common-area lighting, elevators and pumps, and the risk of hitting the top EVN tiers when tenants use a lot.

Question 3

How much electricity does an air conditioner use in Vietnam?

Accepted Answer

A modern 9,000–12,000 BTU inverter AC at 25–26°C uses about 0.6–0.9 kWh per hour. Running 12 hours a day, that adds up to about 250–350 kWh a month (roughly 1.0–1.5 million dong). Old non-inverter units can use twice as much.

Question 4

How to save on electricity in Vietnam?

Accepted Answer

1) Don't set the AC below 25–26°C — each degree lower adds 7–10% consumption. 2) Run a ceiling fan together with the AC to circulate air. 3) Close blackout curtains during the day against direct tropical sun. 4) Clean AC filters regularly (every 2–3 months).

Question 5

What to do if the electricity bill is abnormally high?

Accepted Answer

Compare the meter reading with the numbers on the bill. If they match, check the fridge door seals and the water heater for leaks. If you suspect a faulty meter, contact the building manager or call an EVN technician.
