First 200 Units at No More Than 3 THB/Unit — Do Dorm & Rental Tenants Get It?
The new residential rate table is in force from the Sep 2026 bill cycle: the first 200 units carry an energy rate of no more than 3.00 THB/unit. The separate move to widen the residential DEFINITION to dorms, apartments and rental houses has not been notified — and the right that does exist 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 new residential rate table charges the first 200 units at no more than 3 THB/unit on the utility bill automatically, in force from the Sep 2026 bill cycle, no registration needed (the ERC confirmed the first-200-units ≤3 THB rate from the Sep 2026 bill in its press release of 7 Sep 2026 — but the residential-user DEFINITION covering dorms and apartments still has no official notification). (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.
A Home With No House Registration: What Is the Rate per Unit from the Sep 2026 Bill?
The first 200 units at no more than 3 THB/unit — the same as a home that has house registration, down from the "temporary electricity" rate of 6.8024 THB/unit. It applies from the September 2026 electricity bill onward, under the ERC resolution announced on 7 Sep 2026. From unit 201 the ordinary residential progressive tiers apply.
Who qualifies — the two conditions
The ERC set two conditions: (1) the supply must actually be used for dwelling, not temporary supply for construction work, and (2) at least 6 months of bill-payment history. The ERC's stated reason is that many homes without house registration have been billed at the temporary rate for more than 10 years despite using the electricity to live in permanently. The measure covers roughly 40,000 households.
How to check whether the utility has actually re-rated you
Open your September 2026 bill or later and check whether, for usage under 200 units, the energy charge is now at 3 THB/unit. If you are still being billed at the temporary rate, the ERC has opened reporting channels: the LINE Official Account "กกพ. รับแจ้งปัญหา" (@ERCvoice), the สำนักงาน กกพ. Facebook page, or 0-2207-3599 and 1204 during office hours.
⚠️ This does not mean dorms and apartments have been reclassified as residential. The ERC's 7 Sep 2026 press release covers only "temporary meters serving dwellings without house registration". It says nothing about the residential-user definition covering dorms and apartments, which still has no official notification. If you rent a room and pay through the landlord's sub-meter, what you pay is still governed by the OCPB rules on rental electricity exactly as before — see also the 2026 dorm electricity law.
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), the ERC's consultation notice (27 Jul 2026), and the MEA/PEA Type-1 rate table effective with the Sep 2026 bill — every point verified against official sources (listed at the bottom). The rate and the start date are no longer a plan: the ERC resolved on 5 Aug 2026 and the new rates are published in the official tariff table, effective with the Sep 2026 billing statement:
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 residential progressive tiers in the same rate table apply — and the two upper tiers (201–400 and 401+) were cut in the same revision. All of these are energy rates: 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
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 was approved by the ERC on 5 Aug 2026 and now sits in the MEA/PEA tariff table — see "Current Status" below.
The definition (part settled)
Half of it has landed: the Type-1 definition in the Sep 2026 rate table now includes "continuous residential use without permanent house registration". But the words dorm, apartment and rental room appear in no official document — so classifying dorm and apartment operations as residential is still un-notified.
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 ENERGY rate on the first 200 units in the official Type-1 tariff table effective with the Sep 2026 bill — 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 Sep 2026 tariff table rate) | 600.00 THB |
| + Ft charge — 200 units × 0.1623 THB/unit (Sep–Dec 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: up to the Aug 2026 bill the same home paid about 4.04 THB/unit (a 808.31 THB bill), so from the Sep 2026 bill it saves 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) The old open question — whether 3.00 THB was already an all-in figure — is now closed: the conditions printed under the Sep 2026 tariff table state that the tabled rates are "exclusive of VAT" and that each month's charge is the base tariff plus Ft, the latter "shown as a separate line on the bill". The conservative reading used here matches the official document. 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 |
| 5–14 Aug 2026 | The ERC resolves (5 Aug 2026) to restructure the residential progressive tariff under the NEPC resolution of 15 Jul 2026, and MEA publishes its press release on 14 Aug 2026 — effective with the Sep 2026 billing statement. This is the point at which the rate stopped being a plan and became the official rate table |
| Aug 2026 | Per the government's plan: the first month metered on the new rate (the usage month, not the month you pay) |
| 7 Sep 2026 | ERC announces its resolution: the utilities move dwellings without house registration off the 6.8024 THB/unit temporary rate and onto the same rate as registered homes (first 200 units ≤3 THB), from the Sep 2026 bill — this does not cover the residential-definition revision that would include dorms and apartments |
| 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 |
| Pending | Classifying dorm / apartment / rental-house operations as residential users — still no official notification as of this page's update date (the Sep 2026 Type-1 definition widens only to "continuous residential use without permanent house registration"; the words dorm and apartment do not appear) |
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 the official tariff notification has since arrived: the ERC resolved on 5 Aug 2026 and the new MEA/PEA Type-1 rate table applies from the Sep 2026 billing statement onward.
Current Status: The ERC Has Settled One of the Two Items — the Other Is Still Open
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 were on the table together — and as of this page's update they have not moved at the same speed:
- ✅ The residential progressive rate — the first 200 units at an energy rate of no more than 3 THB/unit · Settled, no longer a proposal: the ERC resolved on 5 Aug 2026 (MEA press release, 14 Aug 2026) and the new rates are printed in the MEA/PEA Type-1 rate table effective with the Sep 2026 bill — the ERC's press release of 7 Sep 2026 restates it
- ⏳ Whether dorms, apartments and rental houses become residential users · Still no official notification. The Type-1 definition genuinely was amended in the Sep 2026 rate table — but the amendment adds only "continuous residential use without permanent house registration". The words dorm, apartment and rental room appear nowhere in the text, and the 7 Sep 2026 press release does not mention the point either
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. The Sep 2026 amendment moved that boundary by one step, but a narrow one: it admits dwellings that are genuinely lived in yet have no permanent house registration — not dorm operations. If the next step comes, rental buildings move onto the residential structure and the first-200-units right lands on the master meter. If it does not, or comes with conditions, a share of buildings stays on the business tariff — which is why the text of the 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).
