First 200 Units at No More Than 3 THB/Unit — Do Dorm & Rental Tenants Get It?
The state has extended the residential tariff class to dorms, apartments, and rental houses — but the right attaches to the utility meter, not the sub-meter in your room. Verified facts, the numbers that matter, and what tenants can actually do.
Yes — but the right attaches to the building's UTILITY meter: the NEPC resolution extends the residential class to dorms, apartments, and rental houses, so the building's utility bill automatically charges the first 200 units at no more than 3 THB/unit from the Sep 2026 bill cycle, no registration needed. What a sub-meter tenant actually pays still depends on the landlord — who, under the OCPB rules, must not profit on electricity (official calculation-method cap 4.88 THB/unit). Check your September bill carefully.
What the "First 200 Units ≤3 THB" Measure Is (Verified Facts)
Summarised from the NEPC resolution (29 Apr 2026), the Interior Deputy Minister's press briefing at PEA HQ (20 Jul 2026), and the deputy government spokeswoman's clarification (23 Jul 2026) — every point verified against official statements (sources at the bottom):
The rate
A residential customer's first 200 units are billed at no more than 3 THB/unit; from unit 201 onward the existing progressive rates apply.
Automatic
It is automatic for every residential household — no registration and no app required.
When it starts
It applies to electricity used from Aug 2026, collected in the Sep 2026 bill cycle onward (bills dated around 14 Sep 2026 per the PEA/MEA briefing).
Extended to rentals
The "residential user" definition is revised to cover dorm, apartment, and rental-house operations — including temporary house registrations and temporary meters — so those buildings get the same residential rate, and operators can bill tenants at appropriate, fair rates.
Public lighting separated
The public-lighting burden of roughly 0.09 THB/unit will be separated out of household bills.
Welfare card (a separate measure)
State-welfare-card holders keep the separate support of up to 315 THB/household/month — that one DOES require registering with the utility (open 20 Jul–30 Sep 2026), unlike the automatic first-200-units right.
Do Tenants Paying Through the Landlord's Sub-Meter Get 3 THB?
Not automatically — the 3-THB right materialises on the building's utility bill (the landlord's account), not on the sub-meter in your room. The landlord's electricity cost goes down; you benefit only if that saving is passed through — which the OCPB rules already require, since landlords must not profit on electricity.
Why this matters: the CapSolar July 2026 survey of 400 sampled listings nationwide found 98.8% of listings that advertise an electricity rate already charge above the 4.88 THB/unit cap (median 7 THB/unit = 1.43× the cap). If your building charges 7–8 THB/unit today, the 3-baht measure widens the gap between the landlord's true cost and what you pay even further.

The Three Most-Confused Numbers — What Each One Is
| Number | What it is | Where it applies |
|---|---|---|
| 3.00 THB/unit | The state-set maximum for the first 200 units (NEPC resolution) | The MEA/PEA bill at the building's utility meter — from the Sep 2026 bill cycle |
| 3.95 THB/unit | The residential blended system average for the current period (your fairness yardstick) | A reference figure, not a direct bill rate — see price per unit 2026 |
| 4.88 THB/unit | The OCPB official calculation-method cap (2025 lease contract-control notification) for landlords billing via sub-meters — no profit allowed | What the landlord charges the tenant — legal detail on the rental electricity law page |
The key point: 3 THB is what the UTILITY charges the building's bill for the first 200 units — it is NOT a new cap on what your landlord may charge you. The tenant-side ceiling remains the OCPB rule (official calculation-method cap 4.88 THB/unit, no profit).
What Tenants Can Do (3 Steps)
1) Check your building's per-unit rate
Read your lease/room bill for the per-unit rate and enter it in the free rental electricity checker — it instantly compares against the OCPB calculation-method cap. From the Sep 2026 bill cycle you can also ask to see the building's utility invoice to confirm it now gets the residential rate (including the first-200-units right).
2) Know your legal rights
The OCPB contract-control notification (2025) lets landlords bill electricity at no more than what the utility actually charges plus genuine costs — no profit (official calculation-method cap 4.88 THB/unit). Clauses charging above that have no legal effect even if signed. Plain-language version on the rental electricity law page.
3) If overcharged — three hotlines
Per the Interior Deputy Minister's briefing (20 Jul 2026), tenants of dorms/apartments/rental houses charged above what the state prescribes can report via the Damrongdhama Center 1567, the Public Service Center 1111, or the OCPB hotline 1166 for the authorities to investigate.
