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 as planned, no registration needed (the rate itself still awaits the ERC's official notification — its consultation closed on 31 Jul 2026). (That 3.00 is the ENERGY rate — Ft, the monthly service charge and 7% VAT are still added on top, so a home using exactly 200 units pays about 3.52 THB/unit all-in.) 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 resolutions (29 Apr and 15 Jul 2026), the Interior Deputy Minister's press briefing at PEA HQ (20 Jul 2026), the deputy government spokeswoman's clarification (23 Jul 2026), and the ERC's consultation notice (27 Jul 2026) — every point verified against official sources (listed at the bottom). Note that "when it starts" is the government's plan and still awaits the ERC's official tariff notification:
The rate
A residential customer's first 200 units carry an energy rate of no more than 3 THB/unit; from unit 201 onward the existing progressive rates apply. This is the energy rate — Ft, the monthly service charge and 7% VAT are added separately.
Automatic
It is automatic for every residential household — no registration and no app required.
When it starts
Per the government's plan: 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 of 20 Jul 2026). The rate still awaits the ERC's official notification — see "Current Status" below.
Extended to rentals
The "residential user" definition is to be 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. This one is still a PROPOSAL: it has just been through the ERC's consultation (24–31 Jul 2026) and is not yet an effective notification.
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 ENERGY rate for the first 200 units (NEPC resolution) — it excludes Ft, the monthly service charge and 7% VAT, so it is not directly comparable with the two rows below | The MEA/PEA bill at the building's utility meter — from the Sep 2026 bill cycle. A home using exactly 200 units pays about 3.52 THB/unit all-in (worked out in the next section) |
| 3.95 THB/unit | The residential blended system average for the current period (your fairness yardstick) — this figure is all-in: Ft and VAT included | 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. This figure is all-in: Ft and VAT included | What the landlord charges the tenant — legal detail on the rental electricity law page |
The key point: 3 THB is the ENERGY charge the utility applies to the building's first 200 units (Ft, the service charge and VAT are still added on top) — and 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).
So Does "3 THB" Mean the Bill Works Out at 3 THB/Unit?
No — and the news reports are not wrong, they just stop one step short. The 3.00 THB/unit figure is the energy rate (the progressive tier rate) only. Every Thai electricity bill still adds three more lines on top: the Ft charge, the monthly service charge, and 7% VAT. The rate sheet put to public hearing says so explicitly — the rates are quoted "excluding the monthly service charge, the fuel adjustment charge (Ft), and VAT" (Thairath, 23 May 2026). So a home using exactly 200 units (Type 1.2) gets a bill like this:
| Bill line | Amount |
|---|---|
| Energy charge — first 200 units × 3.00 THB/unit (the measure's rate) | 600.00 THB |
| + Ft charge — 200 units × 0.1623 THB/unit (May–Aug 2026) | 32.46 THB |
| + Monthly service charge (residential Type 1.2 — flat) | 24.62 THB |
| Subtotal before VAT | 657.08 THB |
| + 7% VAT | 46.00 THB |
| Total bill → average per unit | 703.08 THB → 3.52 THB/unit |
The number to remember: a home using 200 units a month actually pays about 3.52 THB/unit (a 703.08 THB bill), not 3.00 THB/unit — but it is a real cut, because the same home pays about 4.04 THB/unit today (a 808.31 THB bill), a saving of roughly 105 THB/month.
Two caveats: (1) Ft and VAT apply to every unit, including the first 200 — not only from unit 201 up. (2) This works from the current bill structure on the conservative (higher-bill) reading; if the ERC's official rate schedule states that 3.00 THB is already an all-in figure, the real number will be lower and this page will be updated accordingly. To try your own monthly units, use the electricity bill calculator — it runs on the same rate set as this table.
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.
Timeline
| Date | What happens |
|---|---|
| 29 Apr 2026 | NEPC resolves in principle: first 200 units at ≤3 THB/unit (alongside the residential solar buy-back measure) |
| 15 Jul 2026 | NEPC approves the 2026–2030 tariff-structure policy and tasks the ERC with MEA/PEA/EGAT to draft the progressive-rate revision for the first 200 units and the revision of the residential-user definition — this is the resolution the ERC is now acting on |
| 20 Jul 2026 | Interior Deputy Minister at PEA HQ: right extended to dorms/apartments/rental houses; welfare-card registration opens (until 30 Sep) |
| 24–31 Jul 2026 | ERC public hearing on the three utilities' proposal — both the first-200-units progressive rate and the residential-user definition. Comments closed on 31 Jul 2026 |
| Pending | The ERC deliberates and gives the statutory approval, then issues the official tariff notification — as of this page's update date no notification has been published |
| Aug 2026 | Per the government's plan: the first month metered on the new rate (the usage month, not the month you pay) |
| Sep 2026 | Per the government's plan: the first bill cycle showing the new rate (bills dated ~14 Sep 2026) — the moment tenants should check their own bills |
On "August or September": both months are correct but they mean different things — August is the USAGE month, September is the BILL CYCLE in which you see the reduction. The "starts with the August bill" headlines come from the Energy Minister's 15 Jul 2026 remarks, which used "คาดว่า…ได้ทัน" (expected to make it in time) and "เร็วที่สุด" (at the earliest) — a forecast, not a schedule. The 20 Jul 2026 joint briefing with MEA/PEA then stated plainly that it "will begin operating in August 2026 and the saving will appear in the September 2026 bill cycle". This page follows that wording and will be updated the moment the ERC issues its official tariff notification.
Current Status: The ERC Hearing on the Progressive Rate Has Closed — Decision Pending
Before the new rate can actually apply it has to clear the ERC, and that step is not finished. From 24 to 31 Jul 2026 the Energy Regulatory Commission ran a public consultation on the joint proposal from MEA, PEA and EGAT, made under the NEPC resolution of 15 Jul 2026. Two things are on the table together:
- The residential progressive rate — setting the first 200 units at no more than 3 THB/unit
- The revision of the residential-user definition — whether dorms, apartments and rental houses count as "residential"
Why the "residential user" definition is the part that matters most to tenants
Because many dorms and apartment buildings are not on the residential tariff to begin with — the building's master meter is commonly registered as a small-business / commercial customer, a different rate structure altogether. That boundary decides which set of rates the landlord's "actual cost" pass-through to you is measured against. If the new definition passes, rental buildings move onto the residential structure and the first-200-units right lands on the master meter. If it does not pass, or passes with conditions, a share of buildings stays on the business tariff — which is why the ERC's official notification matters more than the headlines.
What is unchanged while we wait: the tenant-side rule is still the OCPB notification — the principle being that a landlord cannot charge you more than the landlord is charged by the utility. Whatever number the ERC lands on, that principle does not move.
This page tracks the ERC's own announcements and will be updated when a decision lands. To confirm your building's billing status in the meantime, call the utility directly: MEA 1130 (Bangkok, Nonthaburi, Samut Prakan) or PEA 1129 (elsewhere).
