Why did my KSEB electricity bill suddenly double?

Electricity bill doubling in Kerala is typically caused by one of five reasons: seasonal air conditioning during hot humid months, crossing the 250-unit non-telescopic cliff, annual Additional Cash Deposit (ACD) charges, delayed meter reading extending past 60 days, or household earthing leakage.

How does a delayed meter reading increase my electricity bill?

If a meter reader arrives on Day 64 or 66 instead of Day 60, four to six extra days of consumption are included. If not normalized proportionally, this can unfairly push a household across the 500-unit bi-monthly cliff into higher non-telescopic flat rates.

Diagnostic Progress: 0 of 5 Checked

Mark items that apply to your household to narrow down the cause of your bill jump.

1. Seasonal Air Conditioner & Cooling Surge

Did AC or cooling usage increase during warm/humid months?

▲

Diagnostic Question: Did your household use an Inverter AC for 6+ hours daily over the last 60 days?

A 1.5-ton 3-star inverter AC typically consumes 1.2 to 1.5 units per hour of operation. Running one AC for 7 hours each night adds approximately 8 to 10 units daily—totalling 480 to 600 units across a 60-day billing cycle by itself.

3. Additional Cash Deposit (ACD) Demand

Is there an unexplained lump-sum line item on your bill?

▼

4. Delayed Meter Reading (>60 Days Cycle)
