Tamil Nadu: 200 Units of Free Electricity Announced for Domestic Consumers in 2026

On May 10, 2026, Tamil Nadu's newly sworn-in Chief Minister C. Joseph Vijay signed an order granting 200 units of free electricity per month to domestic consumers. The order was among the first official files signed by the new government following the swearing-in ceremony held at the Jawaharlal Nehru Indoor Stadium in Chennai.

This is a significant announcement for Tamil Nadu households and, by extension, for anyone trying to estimate their TNEB electricity bill. Here is what we know so far.

What Was Announced

Chief Minister C. Joseph Vijay signed an official order for 200 units of free electricity for domestic consumers on his first day in office. The order was signed in the presence of senior officials and cabinet ministers.

The announcement is part of the new government's stated welfare agenda. Alongside the electricity order, the CM also signed orders for a women's safety task force and an anti-drug task force.

What This Means for Your TNEB Bill

Under the current TNEB tariff (effective July 1, 2024), the first 100 units are free for all domestic consumers, regardless of total monthly consumption. Even if you consume 500 or 1,000 units in a month, the first 100 units remain at zero cost. What changes as consumption crosses thresholds is the rate applied to the units beyond 100, not the free slab itself.

If the new 200-unit free electricity order is implemented, it would represent a substantial change to how domestic bills are calculated. For households consuming 200 units or fewer in a month, the bill could potentially come to zero.

However, the exact mechanism has not yet been officially notified by TNEB or TANGEDCO. Key questions that remain unanswered include:

• Will the free 200 units apply regardless of total consumption, or only for households consuming 200 units or fewer?
• Will the existing progressive slab structure be revised alongside this?
• Will there be any applicable fixed or demand charges?
• What category of domestic consumers will be covered?

Until TNEB or TANGEDCO releases an official revised tariff order, we do not have enough information to update the calculator accurately.

What the Calculator Currently Shows

The TNEB Bill Calculator currently uses the tariff structure effective from July 1, 2024. This is the last officially published and notified TNEB tariff. The calculator accurately reflects that structure.

We have not made any changes to the calculator based on the new announcement because the implementation details are not yet available. Updating the calculator with assumptions could lead to incorrect bill estimates, which we want to avoid.

What to Expect Next

Once TNEB or TANGEDCO publishes an official gazette notification or circular that details how the 200-unit free electricity scheme will be structured, we will:

1. Update the tariff slabs in the calculator to reflect the new rates.
2. Publish a detailed article explaining the revised structure.
3. Update the tariff details page with the new slab breakdown.

We recommend bookmarking this page and checking back once the official revised tariff is published.

In the Meantime

You can still use the current calculator to understand how your bill is calculated under the existing tariff. If you are a household that consumes close to or below 200 units per month, the upcoming change, once implemented, could bring your bill to zero or significantly reduce it.

Use the calculator to check your current estimated bill based on your recent meter readings, and compare it once the updated tariff is live.
