Thailand generally produces approximately 170 TWh of electrical energy annually, with nearly 90% dependent on natural gas. Hydroelectric production accounts for only 3.2% of the energy supply. The rate is set by the Ministry of Energy at 2.6 baht per kW. This country therefore has one of the most extensive electrical networks in Southeast Asia.

Thailand's electrical voltage shows a slight difference compared to what you'll find in Europe. Thailand operates at 220 V with a frequency of 50 Hz, versus 230 V at 50 Hz in Europe. However, this shouldn't pose a problem, since the majority of electrical appliances can function normally as long as the electrical power doesn't exceed a certain tolerance level. Before heading to the Kingdom of Siam, you should check whether your device bears a label like this: « Input: 100-240V, 50/60 HZ ». This indicates that the device can be used with a voltage between 100 and 240 V.

Do You Need an Adapter for Outlets?

In Thailand, you'll find all outlet types—namely A/B/C. An adapter isn't always necessary since the vast majority of hotels, restaurants, and similar establishments have type C or F outlets, just as you'd find in France.

However, you may occasionally encounter type A, B, or even type I outlets, in which case an adapter becomes essential. We therefore recommend traveling to Thailand with a universal power adapter as a precaution.
