Why a PDF, Not Just the Live Calculator?
The live online TNEB calculator is the best tool for calculating an estimated rupee bill down to the paisa. However, a single-page printable reference card serves tangible real-world needs that a smartphone browser cannot replicate:
1. Pinned Notice Board Reference
Display at residential society notice boards, apartment security desks, or commercial billing counters for instant reference by staff and residents without requiring mobile internet.
2. Transparent Tenant Billing
Share directly with tenants to verify their sub-meter portions and eliminate disputes regarding slab jumps, free unit allocations, or commercial reclassifications.
3. Senior Citizen Friendly
Print and hand to elderly family members who prefer reviewing paper documents and checking their white meter card readings manually against printed official rate tables.
4. Reliable Offline Storage
Store in your device's files app or print out for remote sites, workshops, or agricultural pump houses where mobile signal is intermittent.
What's on the Card
The reference sheet condenses Tamil Nadu's multi-layered tariff structure into four clearly demarcated, color-coded tables:
- Domestic (LT-1A), 200 Free Units Scheme: Applicable for bi-monthly usage up to 500 units under the 10 May 2026 Government Order. Outlines 0–200 units (₹0.00), 201–400 units (₹4.70), and 401–500 units (₹6.30).
- Domestic (LT-1A), 100 Free Units Baseline: The unchanged progressive schedule that takes over the moment consumption exceeds 500 units in a 60-day cycle. Lists all 8 progressive tiers up to ₹11.55/unit.
- Commercial (LT-V): Rates for retail shops, private offices, clinics, and showrooms (₹6.50 for 1–100 units, ₹9.80 for units above 100, plus ₹150/kW fixed load charge and 5% electricity duty). For in-depth commercial analysis, see our TNEB Commercial Bill Calculator.
- Worked Examples Reference: Quick reference table mapping bi-monthly consumption from 100 units to 800 units, noting that calculations above 500 units are not verified.
How to Read a Telescopic Slab Table
If you have never computed utility bills using a slab card: each row applies only to the units that fall inside that specific numerical tier, not to your total consumption.
For example, if your meter reads 350 units in a 60-day billing cycle:
- Units 0 to 200: Free under the May 2026 enhanced subsidy (₹0.00).
- Units 201 to 350 (150 units): Billed at ₹4.70/unit = ₹705.00.
- Units above 350: None consumed = ₹0.00.
- Total Bill: ₹705.00.
If you wish to model custom consumption numbers offline, our TNEB Excel Calculator Guide provides a pre-built spreadsheet with automated formula cells. For a side-by-side historical comparison between the old 100-unit and new 200-unit schemes, consult our TNEB Old vs New Tariff 2026 Guide.
Keep This Reference Card Updated
State electricity tariffs are subject to regulatory updates. The 10 May 2026 order doubling free units is a prime example of how subsidy guidelines evolve. If you print this reference card for long-term use, verify the "Updated" date printed at the top. We re-generate the PDF whenever new orders are gazetted. For live real-time rates, visit our TNEB Bill Calculator or explore our national directory at All India Electricity Tariffs.
Frequently Asked Questions: TNEB Tariff Card PDF
Clear answers on document provenance, printing tips, and commercial coverage.
Is this PDF an official TNPDCL / TNEB document?
No. This is an independent reference card compiled from published TNERC tariff orders and the 10 May 2026 Tamil Nadu Government Order. It is not issued by or affiliated with TNPDCL, or the Tamil Nadu Government.
Does this PDF cover commercial rates too?
Yes — it includes both domestic (LT-1A) with the 200/100 free units scheme and commercial non-domestic (LT-V) tariff tables on the same printable page.
How often is this PDF updated?
Whenever TNERC or the Tamil Nadu Government formally notifies a tariff revision or modifies subsidy allocations, the PDF is regenerated. Check the 'Updated' date printed at the top of the card, and cross-check against our live online calculator if it has been a while.
Can I print this for my shop or apartment notice board?
Yes. It is formatted specifically as an A4 single-page quick-reference card intended for physical display in apartment lobbies, RWA offices, retail shop counters, and maintenance desks.
