Estimated Readings: What They Mean in Your Electricity Bill
Respuesta rápida
Estimated readings are bill calculations based on your historical energy usage rather than the actual data from your meter. In Spain, these occur when the distributor cannot access your meter or when remote management systems fail to transmit data.

What are estimated readings: what they mean in the bill (without jargon)
In the energy market, an estimated reading is essentially a placeholder. When the distributor cannot communicate with your meter, they use a formula to guess your consumption.
The definition in one sentence
It is a billing method based on historical consumption patterns rather than the actual kilowatts consumed during the billing period.
Where it appears on the bill
You will usually find this in the 'Consumption Details' or 'Meter Information' section of your PDF, often labeled as 'Estimada'.
Why it matters (money, decisions, and typical traps)
Estimated readings aren't just about accuracy; they affect your cash flow and your ability to detect if you are overpaying for power.
The error most common
Paying for energy you haven't used yet, or worse, accumulating a large debt that will be charged all at once when a real reading is finally taken.
The clue almost no one looks at
The 'Regularization' line. If you see this, it means your previous bills were wrong, and the company is now adjusting the balance.
How to check it in 60 seconds (Auditor's checklist)
You don't need to be an expert to spot an estimation. Follow these forensic steps to verify your bill's integrity.
What to look for in the PDF
Search for the keywords 'Real' and 'Estimada'. If 'Estimada' appears frequently, your bill is not reflecting your current habits.
What to write down to compare
Note the final reading number on your bill and compare it to the number displayed on your digital meter screen today.
If you want certainty: autopsy your bill and decide with numbers
Stop guessing and start auditing. A forensic look at your bill reveals more than just consumption errors.
What ahorr.ai detects
We identify power mismatches (paying for more than you use), hidden maintenance services, and how your rate compares to the current market.
What to do with the result
Use the data to adjust your contracted power, cancel 'vampire' services, or switch to a provider that offers better terms for your profile.
Auditor's Checklist for Estimated Readings
- ✓Locate the 'Reading Type' (Tipo de Lectura) section in your PDF
- ✓Verify if the status is marked as 'Real' or 'Estimada'
- ✓Compare the reading on the bill with the number currently on your physical meter
- ✓Check for a 'Regularization' (Regularización) line in the billing breakdown
- ✓Evaluate if your contracted power matches your actual peak usage recorded in the meter
Reading Types and Their Impact
| Term | Meaning | Financial Impact |
|---|---|---|
| Real Reading | Actual data from your smart meter | Accurate billing of what you used |
| Estimated Reading | A calculation based on previous years | Risk of overpaying or a future 'bill shock' |
| Regularization | Adjustment after a real reading is taken | Sudden high bill to cover past underestimations |
Estimated readings often hide inefficiencies like oversized power capacity.
The Case of the 90m² Apartment Overpayment
A family living in a standard 90m² apartment noticed their bills were consistently high despite being away for weeks. Upon inspection, they found months of estimated readings. Worse, they were paying for 4.6 kW of contracted power while their actual peaks never exceeded 2.8 kW, leading to a constant drain on their finances regardless of their actual usage.
Hallazgos
- ✓4.6 kW contracted vs 2.8 kW actual peaks
- ✓€6.99/month wasted on unnecessary extra services
- ✓Effective rate of €0.23/kWh due to hidden inefficiencies
