Understanding PEA Rates in Phuket (2026)
Thailand's electricity system is managed by PEA in Phuket, and rates are tiered based on monthly consumption. The more you use, the higher your per-unit cost. Here's the official 2026 breakdown:
| Consumption (kWh/month) | Rate per Unit (THB) |
|---|---|
| 0–150 units | ฿3.2482 |
| 151–400 units | ฿4.2218 |
| 401+ units | ฿4.4217 |
| Service Charge (single phase) | ฿38.22/month |
| VAT | 7% on total bill |
Example: If you use 600 units (over the 401 threshold), you pay: (150 × ฿3.2482) + (250 × ฿4.2218) + (200 × ฿4.4217) + ฿38.22 service charge + 7% VAT = approximately ฿2,650–2,850 per month.
Real Monthly Cost Examples
What you'll actually pay depends on your lifestyle and how aggressively you use air conditioning. Here are realistic scenarios:
| Living Situation | Est. Monthly Usage | Est. Bill Range |
|---|---|---|
| Studio condo, minimal AC | ~300 units | ฿1,200–1,400 |
| 1BR with AC 8 hrs/day | ~600 units | ฿2,600–2,900 |
| 2BR villa with pool pump | ~1,200 units | ฿5,200–5,800 |
| Family home, 3BR full AC | ~2,000 units | ฿8,800–9,500 |
Why Are Electricity Bills So High?
Air conditioning is the monster energy consumer in Phuket. Here's the breakdown:
The AC Killer
A standard 2.5 TR (ton of refrigeration) inverter air conditioner draws 2,200–2,500W. If you run it 8 hours daily, that's roughly 200–250 units per month, costing ฿850–1,100 alone. Non-inverter ACs are even worse, consuming 3,000W+.
Other Energy Hogs
- Pool pumps: 750W running 8 hrs/day = ~180 units/month (~฿780)
- Water heaters: 4,000W for 2 hrs/day = ~240 units/month (~฿1,040)
- Always-on devices: Fridges, WiFi routers, cable boxes, water filters = 50–100 units/month
- Washing machine & cooking: 30–50 units/month
A 3BR villa with 2 ACs, pool pump, and water heater can easily hit 1,500+ units/month. This isn't unusual—many expat families pay ฿7,000–8,000 monthly.
AC Savings Tips (30–40% Reduction Possible)
1. Inverter vs. Non-Inverter AC
Inverter models (Daikin, Mitsubishi, Samsung) adjust compressor speed continuously, using 30–40% less power than fixed-speed ACs. The upfront cost is higher (~฿15,000–25,000 vs. ฿8,000–12,000), but you'll recoup it within 2–3 years.
2. Set Thermostat to 25°C, Not 18°C
Each degree cooler increases energy use by ~5%. Setting to 25°C (77°F) is comfortable indoors and saves ~฿200–300/month per AC.
3. Use Ceiling Fans
A ceiling fan uses only ~50W, helping circulate cool air. You can set the AC 2–3 degrees higher with a fan running.
4. Install Timer Shutoff
Modern ACs have timers. Set them to turn off 1 hour before you leave home or sleep. Savings: ~฿150–250/month.
5. Block Heat with Curtains & Window Film
Close heavy curtains during peak sun (11am–4pm). Reflective window film can reduce AC load by 20%. Cost: ~฿2,000–4,000 but saves ฿300–500/month long-term.
How to Pay Your PEA Bill
Your bill arrives by the 20th of each month and is due by the end of the month. Multiple payment options:
Online Payment (Fastest)
- PEA Smart Plus App: Download on iOS/Android. Log in with your meter number, view usage, pay instantly. English available.
- Thai Bank Online Banking: Kasikornbank, Bangkok Bank, etc. all accept PEA billers. You need your meter/account number.
- True Money App: Add PEA as a biller, pay without leaving home.
Cash Payment
- 7-Eleven Self-Checkout Kiosk: Bring your printed bill, scan the barcode on the meter number. Pay cash, no fees.
- PEA Office (Phuket Town): Phang Nga Road, near Central Festival direction. Hours 8:30am–4:30pm, Mon–Fri.
- Bank Counter: Any Thai bank accepts PEA payments. Bring your bill.
- ATM: Some PEA-connected ATMs allow direct payment.
Power Cuts in Phuket: Frequency & Prevention
Phuket averages 2–4 power cuts per month, lasting from 5 minutes to 4 hours. Frequency varies by location:
Most Reliable Areas
- Bang Tao / Laguna area: Newer infrastructure, ~1–2 cuts/month
- Patong beach / Central Phuket: Moderate, ~2–3 cuts/month
Frequent Outage Areas
- Rawai & Chalong hills: Older distribution lines, 3–5+ cuts/month, especially in rainy season
- Kamala & north Phuket: Rural areas, occasional longer outages
Reporting & Prevention
Report outages: Call PEA hotline 1129 (24/7) or use PEA Smart Plus app. They'll text you ETR (estimated time to restore).
UPS/Battery Backup for WFH: If you work from home, invest in an uninterruptible power supply (UPS). A 1,500VA model costs ฿3,000–5,000 and provides 30–60 minutes of backup power for laptops, WiFi, and lights.
Pro tip: Keep your meter number (on your bill) saved. You'll need it to report outages, pay bills, or register for PEA Smart Plus.
Setting Up Electricity as a New Tenant
The process depends on your rental type. Most of the time, your landlord handles it.
Renting a Condo
The landlord or building management sets up the account in their name. You simply pay the bill to the landlord or they provide your share. No PEA registration needed for you.
Renting a House (Not a Condo)
You may need to register your own account with PEA. Here's what you'll need:
- Passport (original + 2 copies)
- Rental contract
- 4 passport-sized photos (4×6 cm)
- Deposit: ฿2,000 (refundable at end of tenancy, minus any outstanding balance)
- Proof of residency (from landlord or police letter)
Process: Visit the PEA office on Phang Nga Road, Phuket Town. Bring the above documents. They'll register your account within 1–2 business days. Your first bill arrives 30 days later.
Landlord tip: If your landlord pays PEA upfront, ask to see the bill and meter reading. Some landlords inflate electricity costs to expats; knowing your actual usage protects you.

Frequently Asked Questions
Most modern appliances sold in the US/UK are dual voltage (110–240V), so they'll work fine. Check the label on your device—it should say "100–240V, 50–60Hz" or similar. If not, you'll need a step-down converter (฿500–2,000).
Thai plugs are typically Type A (two flat pins) or Type C (European round pins). You'll need plug adapters (฿50–100 per set from 7-Eleven or BigC).
Call PEA hotline 1129 (24/7, Thai-speaking). They'll ask for your meter number and address, then provide an estimated time to restore.
Alternatively, use the PEA Smart Plus app (iOS/Android) to report the outage. They'll text you updates.
Villas: Yes, you can install rooftop solar. Thailand's EGAT has a net metering scheme that lets you sell excess power back to the grid, reducing your bill.
Condos: Building rules usually prohibit rooftop panels. Some allow small balcony systems, but check with management.
Consult a local installer like Viron Solar or Sunwatt Thailand. Typical 5kWh system costs ฿200,000–300,000 and pays for itself in 6–8 years.
Air conditioning is the main culprit. A 2.5 TR inverter AC uses 2,200–2,500W; running it 8 hours daily costs ฿850–1,100/month just for the AC.
Other factors: pool pumps, water heaters, and always-on appliances. If you're in a 2BR villa with 2 ACs, pool pump, and water heater, ฿5,000–6,000/month is normal.
Action: Check your meter usage via PEA Smart Plus app, identify peak times, and adjust AC settings or install solar to offset costs.
Yes. Use the PEA Smart Plus app (fastest), your Thai bank's online banking (all major banks accept PEA billers), or True Money app.
You can also pay in person at 7-Eleven self-checkout (scan barcode), any Thai bank counter, or the PEA office on Phang Nga Road.
