Is this the official TNEB or TANGEDCO website?

No. Thiyagione is an independent tool and is not affiliated with TNEB, TANGEDCO, or any government electricity board. It only provides an estimate based on configured tariff data.

How accurate is the electricity bill estimate?

The calculator estimates your energy charges using slab-wise tariff rates. Your actual bill may differ due to taxes, additional charges, meter reading adjustments, or tariff revisions.

What are electricity units (kWh)?

A unit of electricity equals one kilowatt-hour (kWh) — the energy used by a 1,000-watt appliance running for one hour. Your electricity meter records total units consumed.

Will calculators for other states be added?

Yes. The website is designed to support many Indian states and electricity boards. Tamil Nadu is available first, with more states being added over time.
