Why is my electricity bill high even though my rate looks low?
A high bill can come from more usage, a narrow advertised rate, missed credits, delivery, fixed fees, billing adjustments, or several causes together.

30-second answer
The answer depends on the full formula.
A low-looking rate does not guarantee a low bill. The amount due combines quantity used with the plan formula, TDU delivery, fixed charges, credits, taxes, and sometimes non-recurring balances or adjustments.
Separate usage change from price change first. If kWh rose, explain why the household used more before blaming the plan. If effective cost rose at similar or lower kWh, inspect credits, fees, tiers, time windows, contract status, and bill adjustments. Without a comparable prior bill and current plan documents, use NEEDS_INFORMATION.
Key facts
What is known—and on what basis
Bill identity
Amount due is not the same metric as energy rate; it can include recurring electricity cost and unrelated balances or adjustments.
Delivery remains
TDU delivery charges are distinct from the REP energy charge and normally remain tied to the service territory when the REP changes.
Compare like periods
Billing days, weather, occupancy, estimated reads, and one-time adjustments can make month-to-month totals incomparable.
Why
Why the general answer can reverse
The basic decomposition is quantity × variable price, plus fixed and conditional charges. A lower cents-per-kWh number can be overwhelmed by higher usage; lower usage can still cost more if it loses a bill credit or spreads fixed fees across fewer kWh.
Delivery is a real part of the bill, but switching the REP does not normally remove the TDU assigned to the address. The actionable question is which line items can change and which cannot.
Contract expiration can also move a customer to a different product. A prior fixed price cannot be assumed to continue after expiration, and a new variable/default price needs current evidence.
Evidence
What to check in the actual situation
- Current and prior service dates, billing days, kWh, meter-read status, and total recurring charges.
- Energy, base, minimum-use, credit, TDU, tax, adjustment, prior-balance, and late-fee lines separately.
- Current EFL/TOS and whether the contract expired or product changed.
- Weather, occupancy, equipment, or schedule changes only as observed context—not as invented causes.
Decision framework
When each Eyebiss label could apply
| Label | Condition |
|---|---|
| KEEP | The higher bill is explained primarily by supported usage or non-plan items and current plan economics remain competitive. |
| WAIT | A known timing boundary, such as contract expiration, makes later reconsideration better supported than action now. |
| SWITCH | Complete, current evidence shows a better household outcome after fees, remaining term, and comparable plan mechanics are included. |
| NEEDS_INFORMATION | The bill, EFL, contract, usage history, location, or current alternative evidence is missing, stale, or conflicting. |
Worked example
Decompose before recommending
Suppose two bills use the same plan. One rises from 800 to 1,200 kWh while the recurring effective rate stays 15 cents. The higher total is usage-driven. If both use about 800 kWh but one loses a $75 credit, the higher total is structure-driven.
- Normalize both bills by service days and separate recurring electricity charges from balances and adjustments.
- Compare kWh and the supported effective-rate numerator.
- Trace any difference to usage, price mechanics, or non-recurring items before assigning an action.
Edge cases
Where the answer needs more care
- A catch-up or estimated meter read can shift usage between bills.
- A short first bill should not be annualized as if it were a full representative month.
- Outages, shutoff risk, wiring, or equipment safety are not retail-plan decisions and need the appropriate utility or safety response.
