Electricity bills are a regular part of life for every household and business in Kerala. When the Kerala State Electricity Board (KSEB) announces tariff revisions, many consumers find themselves confused about what changes to expect and how these will affect their monthly expenses. This guide breaks down the KSEB electricity tariff revisions planned for 2025 to 2027 in simple terms, helping you understand the key points and prepare for the changes ahead.

What Are Electricity Tariff Revisions?
Electricity tariffs are the rates charged by KSEB for the power consumed by customers. These rates can change periodically based on factors such as fuel costs, infrastructure investments, government policies, and inflation. Tariff revisions mean KSEB updates these rates, which can result in higher or lower bills depending on the new structure.
For Kerala residents, understanding these revisions is important because it directly impacts the KSEB Bill you receive every month. The revisions from 2025 to 2027 aim to balance the need for reliable power supply with fair pricing for consumers.
Key Changes in the 2025 to 2027 Tariff Revisions
The tariff revisions announced cover several aspects of electricity pricing. Here are the main points you should know:
1. Revised Slabs for Residential Consumers
KSEB uses a slab system where the price per unit of electricity varies depending on how much you consume. The new revision adjusts these slabs as follows:
Up to 50 units: Slight reduction in rate to encourage low consumption.
51 to 150 units: Moderate increase to reflect rising costs.
151 to 300 units: Higher increase to promote energy conservation.
Above 300 units: Steeper rates to discourage excessive use.
This means if your household uses less electricity, your KSEB Bill might be lower or similar to before. But if you consume more, expect a noticeable increase.
2. Changes in Commercial and Industrial Tariffs
Businesses and industries will see a revision in their tariff categories. The rates for peak hours will increase, encouraging off-peak usage to reduce load on the grid. Additionally, some incentives for energy-efficient practices will be introduced, such as discounts for using renewable energy sources.
3. Introduction of Time-of-Day Pricing
From 2026, KSEB plans to introduce time-of-day pricing for certain consumer categories. This means electricity used during peak hours (evenings) will cost more than during off-peak hours (late night or early morning). This system encourages shifting heavy electricity use to cheaper times, helping reduce overall demand.
4. Fixed Charges and Meter Rent Adjustments
Fixed monthly charges and meter rent will see a small increase to cover maintenance and infrastructure costs. These charges appear as a separate line item on your KSEB Bill and are not dependent on consumption.
How These Changes Affect Your Monthly KSEB Bill
Understanding the impact on your bill helps you plan your electricity use better. Here are some examples:
A family using 100 units per month may see a 5-7% increase in their bill due to slab rate changes.
A household consuming 350 units could face a 10-15% rise because of higher rates in the top slab.
Businesses using electricity during peak hours might pay 20% more unless they shift usage to off-peak times.
By knowing these details, you can take steps to reduce your consumption during expensive periods and save money.

What is Electricity Tariff?
Electricity tariff means the amount we pay for using electricity.
Your electricity bill mainly contains:
Energy Charge → Cost per unit consumed
Fixed Charge → Monthly service charge
Meter Rent & Other Charges
KSEB has slightly increased some charges and kept some categories unchanged.

Important Change: Time-Based Charging (ToD Tariff)
KSEB is introducing Time of Day (ToD) tariff for domestic users consuming above 250 units monthly.
This means electricity price changes depending on the time you use power.
Day Time (6 AM – 6 PM)
10% discount in energy charge
Peak Time (6 PM – 10 PM)
25% extra charge
Night Time
Normal rate
Simple Example
If you use:
Washing machine during daytime → cheaper
Heavy appliances during evening peak time → expensive
So KSEB encourages people to use more electricity during daytime.
