PEA Electricity Rates 2026
The Provincial Electricity Authority (PEA) is the electricity provider for most of Phuket (Bangkok Electricity Authority covers some areas). PEA uses a tiered rate system — the more you use, the higher the rate per unit (kWh). This is the real rate you pay if your unit has a direct PEA meter.
| Monthly Usage (kWh) | Rate per kWh (฿) | Typical Scenario |
|---|---|---|
| 0–150 kWh | ฿3.2484 | Studio, fans only, rarely home |
| 151–400 kWh | ฿4.2218 | 1-bed, moderate AC (4–6hrs/day) |
| 401–1,000 kWh | ฿4.4217 | 2–3 bed, heavy AC use |
| Over 1,000 kWh | ฿4.4217 | Large villa, multiple AC units all day |
There's also a small fixed service charge (฿38–100/month depending on meter size) and a Ft adjustment charge that fluctuates with fuel costs. Your total bill will be slightly higher than the kWh rate alone suggests — typically add 5–8%.
⚠️ The Landlord Surcharge Trap — Most Important Section
The most important electricity fact for Phuket renters
Most rental properties in Phuket do not have an individual PEA meter per unit. The landlord has one master meter and charges tenants separately. Thai law allows landlords to charge a maximum of ฿4.50/kWh over the PEA rate — but many charge ฿7–9/kWh and simply absorb the difference as profit.
On a 400-unit monthly bill, the difference between PEA rate (฿4.42) and landlord rate (฿8.00) is:
400 × ฿3.58 = ฿1,432 extra per month = ฿17,184 extra per year.
This is cash taken directly from you. Always ask your landlord — before signing — whether they charge PEA unit rates or a flat rate per kWh. If they charge more than ฿5/kWh, negotiate or factor it into your rental decision.
Real Monthly Electricity Bills by Lifestyle
These are realistic estimates for different property types at PEA direct rates. Add 50–80% to these figures if your landlord charges ฿7–9/kWh.
| Property Type | AC Hours/Day | Est. Monthly kWh | PEA Rate Bill (฿) | Landlord Rate ฿8/kWh (฿) |
|---|---|---|---|---|
| Studio (1 AC unit) | 4hrs | 80–150 | ฿500–800 | ฿640–1,200 |
| Studio (heavy AC) | 10hrs | 180–280 | ฿900–1,400 | ฿1,440–2,240 |
| 1-bed apartment | 8hrs avg | 300–450 | ฿1,500–2,200 | ฿2,400–3,600 |
| 2-bed apartment | 8–12hrs | 500–750 | ฿2,400–3,700 | ฿4,000–6,000 |
| 3-bed house + pool | 12hrs+ all rooms | 1,000–2,000 | ฿4,800–9,000 | ฿8,000–16,000 |
Air Conditioning Costs Explained
In Phuket's climate (28–36°C year-round), air conditioning isn't optional for most people — it's a health necessity during the hot season (March–May) and a comfort necessity the rest of the year. It typically accounts for 60–80% of expat electricity bills.
Inverter vs Non-Inverter AC
This is the most important AC choice you can make. Inverter AC units adjust their compressor speed to maintain temperature, using 30–40% less power than older non-inverter (fixed-speed) models. If your rental has old non-inverter units, you're paying a significant premium every month.
The rule is: ask about AC when viewing any property. If units are more than 8–10 years old and non-inverter type, either factor in higher electricity costs or ask the landlord to upgrade as part of lease negotiations.
Temperature Setting Impact
- 20°C: Maximum power draw — the AC runs at full capacity
- 24°C: ~15% reduction vs 20°C. Comfortable for most nights
- 26°C: ~30% reduction vs 20°C. Comfortable with a fan
- 26°C + ceiling fan: Wind chill makes it feel like 22°C — and costs 30–40% less than running at 20°C
The single most impactful free action: raise your AC thermostat from 20°C to 25–26°C and add a fan. Most expats who do this report no loss of comfort and 20–35% lower bills.
7 Ways to Reduce Your Electricity Bill in Phuket
- 1. Verify your billing rate: Ask your landlord exactly what they charge per kWh. If it's above ฿5, negotiate or factor it into your rent decision.
- 2. Use inverter AC units: If the property has old non-inverter units, ask for upgrades — landlords often agree to split the cost for long leases.
- 3. Set AC to 26°C + fan: Wind chill makes 26°C feel like 22°C. This single change can cut AC costs 25–35%.
- 4. Turn off AC when leaving: Unlike some humid climates, Phuket properties cool down quickly. Turning AC off for 1–2 hours and restarting is more efficient than leaving it running at 30°C setpoint.
- 5. Don't leave appliances on standby: TVs, monitors, routers and chargers left plugged in add 5–10% to your bill.
- 6. Use the PEA Smart Plus app: If you have a direct PEA meter, the app lets you monitor usage in real-time. Identifying peak usage times lets you adjust behaviour.
- 7. Pool pump timer: If you have a villa with a pool, set the pump to run 6–8 hours overnight at off-peak rate rather than 12 hours all day. Pool pumps are typically 1–2kW — a major bill contributor.
How to Pay Your Electricity Bill in Phuket
If you have a direct PEA meter, payment options include:
- PEA Smart Plus app: Download on iOS/Android. Link your meter number. Pay via credit card or internet banking.
- 7-Eleven: Pay in person at any 7-Eleven using your meter number. Cash or prompt pay.
- AIS / True Move / DTAC stores: Electricity payment available at most service centres.
- PEA office: Phang Nga Road, Phuket Town (near Robinson's Department Store area). Open weekdays 8:00–16:30.
- Direct debit: Set up via your Thai bank account (KBank, Bangkok Bank) — recommend for long-term residents.
If you pay through your landlord, they'll simply include electricity in your monthly bill or invoice separately. Keep records of all electricity payments and the kWh charges — these are useful if a dispute arises.
