Understanding ACD in Your KSEB Bill

If you've been puzzled by the "ACD" line item on your Kerala electricity bill, you're not alone. ACD, which stands for Additional Cash Deposit, is a security deposit mechanism used by KSEB to ensure reliable bill payments and manage consumer accounts effectively.

Unlike your regular electricity charges, ACD is not a monthly fee but rather a one-time or periodic deposit that acts as collateral for your future electricity consumption. This guide will help you understand everything about ACD in 2025.

💡 Did You Know?

ACD helps KSEB maintain financial stability and ensures uninterrupted power supply by securing advance payment for potential future consumption.

Why KSEB Collects ACD

KSEB security deposit system for reliable electricity supply

Security Assurance

Protects KSEB against potential bill defaults and ensures financial security for continuous power supply.

Consumption-Based

Calculated based on your historical usage patterns and consumer category to ensure appropriate deposit levels.

Domestic Consumers

Lower ACD rates for residential connections based on monthly consumption patterns

Commercial Users

Higher ACD requirements due to increased consumption and business usage patterns

Industrial Connections

Substantial ACD amounts reflecting high power consumption and load requirements

How ACD is Calculated

Calculation Formula

ACD = Average Monthly Consumption × Current Tariff Rate × Multiplier Factor

Average Consumption

Based on last 12 months usage or estimated consumption for new connections

Current Tariff

Applicable tariff rate per unit for your consumer category and slab

Multiplier Factor

Typically 2-3 times monthly bill amount, varies by consumer category

📊 Example Calculation

For a domestic consumer with 200 units monthly consumption:

200 units × ₹4.50/unit × 2.5 = ₹2,250 ACD

When ACD Gets Revised

Revision Triggers

Periodic Review

KSEB conducts ACD reviews every 3-5 years or as per regulatory guidelines

Consumption Increase

Significant increase in monthly consumption patterns triggers ACD revision

Tariff Changes

Major tariff revisions may result in ACD adjustments to maintain deposit adequacy
