An unusually high electricity bill often turns out to be a meter-reading mismatch rather than an actual jump in consumption. Most people first assume the tariff went up. Checking reading details on tnebnet.org by Service Number is usually the quickest way to catch this — and if something looks off, a call to 1912 typically gets it sorted in a few days, without an office visit.
TNEB (Tamil Nadu Electricity Board) distribution services now operate through TANGEDCO, rebranded as TNPDCL (Tamil Nadu Power Distribution Corporation Limited) since June 27, 2024. All online services — reading checks, bill payment, account summaries — run through the portal and the official mobile app.
A Service Number and Region Code cover most of what’s needed for reading checks and Quick Pay on tnebnet.org, no login required. As of May 10, 2026, eligible domestic consumers get 200 free units per bimonthly cycle if consumption stays within 500 units, or 100 free units (unchanged) if it exceeds that.
200 Units Free Electricity — Effective May 10, 2026
Following the change in state government after the 2026 Tamil Nadu Assembly election, Chief Minister C. Joseph Vijay announced a revised electricity subsidy as one of the new government’s first major welfare decisions, formalized through an order by the Energy (D3) Department, Government of Tamil Nadu.
| Bimonthly Consumption | Free Units |
|---|---|
| Up to 500 units | 200 units free (the existing 100, plus an additional 100) |
| Above 500 units | 100 units free (unchanged from the previous structure) |
No application is needed — the benefit applies automatically based on existing consumption and billing records with TNPDCL. It isn’t paid in cash; it’s adjusted directly within the electricity bill.
A lot of people still think this 200-unit benefit is monthly. It isn’t — TNEB bills are bimonthly, so the free slab is calculated on the two-month cycle too.
Roughly 90% of Tamil Nadu’s domestic consumers — around 2.23 crore out of 2.46 crore — fall within the 500-unit bimonthly threshold and benefit directly from this expanded free slab. TNERC has separately approved a provisional subsidy of ₹1,545.14 crore to support the scheme’s implementation between May 10, 2026 and March 31, 2027, with the final amount to be reconciled later based on actual consumption data.
If you’re eligible but not seeing the benefit reflected, contacting the local Electricity Department/TNPDCL office for verification is the next step — supporting consumption documentation may be requested.
Checking Your Reading Details
Visit tnebnet.org, select “Bill Status” or “Reading Details,” choose your Region, enter your Service Number and registered mobile number, complete the captcha, and submit. Login isn’t required for this — it’s a direct lookup.
Don’t know your Service Number? It’s on the physical electricity bill or White Meter Card, labeled “Service Connection No.”
Quick Pay — Paying Without Login
On tnebnet.org, select “Quick Pay,” enter the Service Number and Region, confirm the amount displayed, and pay via UPI, Card, or Net Banking. For multiple connections — home plus shop, for instance — saving each Service Number as a Favourite on the portal speeds up future payments considerably.
UPI apps like Google Pay and PhonePe also support direct TNEB bill payment — searching “TNEB” within the app usually surfaces the pending amount automatically.
TNEB Mobile App
Search “TNEB Mobile App” on Google Play Store and install it — this is the official TNPDCL app, using the same Service Number-based lookup for bills, reading, and payment.
Slab Rates Beyond the Free Units
TANGEDCO/TNPDCL sets tariffs based on a proposal submitted to and approved by the Tamil Nadu Electricity Regulatory Commission (TNERC). Beyond the free units, charges apply per slab and increase as consumption rises — under the current tariff order, rates for the 201-400 unit range run roughly ₹4.70-4.95 per unit, climbing to somewhere around ₹11.55-12.15 per unit above 1,000 units bimonthly, though the exact figures are reported slightly differently across sources, so confirming the precise current rate on tnebnet.org or a recent bill is worth doing before relying on any specific number. The bill calculator on tnebnet.org gives a more direct estimate for usage above the free threshold.
Filing a Complaint
Online, tnebnet.org has a Consumer Services → Lodge Complaint option. By phone, 1912 runs 24×7 for both power failure and billing complaints. For power failures specifically, sending “FAULT” plus the Service Number to 9498794987 also works.

A meter-reading discrepancy is often the actual cause behind a suddenly inflated bill — checking reading details directly, rather than assuming a tariff increase, is usually the faster path to a resolution. Beyond that, it’s mostly about remembering to glance at tnebnet.org once in a while and checking whether the household falls under the expanded 200-unit slab.
