Tamil Nadu Electricity Board (TNEB), now known as TANGEDCO (Tamil Nadu Generation and Distribution Corporation), has implemented a progressive tariff structure for 2025 that benefits low-consumption households while ensuring sustainable revenue generation. Understanding this structure is crucial for every Tamil Nadu resident to manage their electricity consumption effectively.
The domestic tariff structure is designed to provide relief to low-consumption households. The first 100 units are provided free of cost as part of the government's welfare scheme.
Commercial and industrial consumers have different tariff structures based on their consumption patterns and contribute significantly to cross-subsidizing domestic consumers.
| Consumption Slab | Rate (โน/unit) | Fixed Charge |
|---|---|---|
| 0-100 units | โน0 (Free) | โน20 |
| 101-200 units | โน2.25 | โน30 |
| 201-400 units | โน4.50 | โน50 |
| 401-500 units | โน6.00 | โน80 |
| Above 500 units | โน8.50 | โน125 |
The Tamil Nadu government provides substantial subsidies to domestic consumers, particularly those with lower consumption. The free electricity scheme for the first 100 units has been a flagship program that has provided significant relief to households across the state.
If your monthly consumption is consistently below 100 units, you only pay the fixed charges. Consider energy-efficient appliances to stay within this beneficial slab.
