Temporary / Construction Electricity Cost Thailand 2026: How Much Per Unit
Before building a house or opening a construction site, you must apply for “temporary power” first. This page explains what a temporary meter (Type-8 user) is, how many baht per unit it costs, why it's pricier than a normal home meter, how much deposit you pay, how to apply, and when to switch to a permanent meter.
A temporary meter (Type-8 user) is charged a single flat rate across all voltage levels — the MEA base energy charge is ~6.8025 THB/unit, then the Ft (0.1623 THB/unit this period) and 7% VAT are added on top, working out to about 7.5 THB/unit all-in. That's nearly double a normal home rate (~3.95 THB/unit average), because it's temporary power — e.g. during house/building construction or a temporary event — through a single meter. You also place a usage deposit sized to the meter. To compare with permanent rates, see how many baht per unit 2026. (The PEA figure may differ slightly — confirm with PEA 1129 / MEA 1130.)
What Is a Temporary Meter / Type-8 Electricity?
Temporary electricity (Type-8 user) is power requested on a temporary basis through a single meter, for non-permanent needs — such as building a house/structure, a special temporary event (a fair, an event, a market), or other temporary use. People commonly call it a “temporary pot” (หม้อชั่วคราว) or “temporary meter”. It's typically used while construction is still underway; once the house/building is finished and ready for real occupancy, you then apply to switch to a permanent meter (residential or business class, per actual use).
Why Temporary Electricity Costs More Than a Permanent Meter
| Item | Temporary meter (Type 8) | Normal home meter |
|---|---|---|
| Pricing structure | Single flat rate, all voltages | Progressive tiers |
| Base energy charge (before Ft/VAT) | ~6.8025 THB/unit (MEA base) | ~3.25–4.42 THB/unit (by tier) |
| Usage deposit | Yes (sized to meter/transformer) | Yes (sized to meter) |
| Used for | Construction / temporary events | An occupied home |
* Both still add the Ft (0.1623 THB/unit, May–Aug 2026) and 7% VAT. The Type-8 rate may differ slightly between MEA and PEA; the 6.8025 base figure is the MEA's — confirm your area's rate with MEA 1130 or PEA 1129. Compare normal home rates in how many baht per unit.
How to Apply for Temporary Power (a Construction Meter)
Apply at your local electricity authority — the MEA (Bangkok, Nonthaburi, Samut Prakan) or the PEA (other provinces). The general steps are:
Prepare documents — the owner/applicant's ID card, proof of land rights or a consent letter, and the construction-site details.
Submit the temporary-use request — state that it's temporary power for construction and specify the meter size you need (based on your construction equipment load).
Place the deposit and pay fees — the deposit is sized to the meter/transformer; if usage exceeds the deposit, the authority may ask you to top it up (the deposit is refundable when you end service).
Meter installation — staff schedule the installation, after which you can start using power on the construction site.
Note: the exact documents, fees and deposit amount depend on the meter size and your area — check and confirm directly with the authority (MEA 1130 / PEA 1129) or your district electricity office.
When Should You Switch to a Permanent Meter?
Because temporary power costs nearly double a permanent meter, you shouldn't keep a temporary meter longer than necessary. Once the house/building is finished, has a house number and is genuinely ready, apply promptly to switch to a permanent meter for your actual use (residential = Type 1, business = the business class) to get the much cheaper tiered rate. During construction, scheduling power-heavy tools (water pumps, cement mixers, welders) efficiently also helps control the pricey temporary cost. See the full picture in the Thai electricity guide.
