How to read an electricity bill
Use the purchased electricity quantity you can defend. The right number is the energy figure in kWh, not the price in EUR.
Find the annual purchased electricity quantity in kWh, map it to Purchased electricity (kWh), and ignore EUR charges or monthly advance payments.
Exact mapping
What to extract and where it goes
Look for
- Annual purchased electricity in kWh
- The billing period that matches the reporting year
- Optional supplier name if you want to fill Supplier (optional)
Enter into
- Purchased electricity (kWh)
- Supplier (optional)
Unit
kWh
If missing
Leave Purchased electricity (kWh) at 0 and continue.
Do not use
- Total amount in EUR
- Monthly advance payment
- VAT, fixed fees, or network fee totals
Visual mapping
Find the line on the document, then place it in the right field
This is the exact behavior we want from both users and assistants: identify the operational quantity, ignore the money amount, and map the quantity into the matching field.
Example electricity bill

Rule
Use annual kWh, not monthly payment amount.
If the selected country/year has no AIB default factor, the user must also enter a documented market-based factor and a source note before continuing.
Recommended workflow
How to use this category correctly
Step 1
Open the electricity bill, supplier portal, or annual statement for the reporting year.
Step 2
Find the purchased electricity quantity in kWh and confirm the billing period.
Step 3
If the supplier shows monthly bills only, sum the monthly kWh values for the full reporting year.
Step 4
Enter the total into Purchased electricity (kWh), and optionally copy the supplier name into Supplier (optional).
Step 5
If the selected country/year has no default AIB factor, add a documented market-based factor and a source note (for example a GO-backed or supplier-specific factor).
Step 6
Do not estimate from the price in EUR. If there is no defensible kWh value, keep the field at 0.
Assistant prompt support
How an assistant should guide the user in this category
Ask the user for the electricity bill or supplier portal screenshot.
Extract the annual purchased electricity quantity in kWh.
Map that value to Purchased electricity (kWh).
If the supplier name is visible, it can also be copied into Supplier (optional).
If there is no default AIB factor for the selected country/year, ask for a documented market-based factor and source note as well.
Ignore prices, taxes, fixed fees, and monthly advance payments.
Structured FAQ
Questions an agent or user might still ask
What if the electricity bill only shows monthly values?
Sum the monthly kWh values for the reporting year and use that annual total in Purchased electricity (kWh).
What if I only see the total price in EUR?
Do not estimate the energy use from the price. Leave Purchased electricity (kWh) at 0 until you have a real kWh figure.
What if the country has no default AIB factor for the selected year?
If electricity consumption is reported, the user must provide a documented market-based factor and a source note. Without that, the correct fallback is to set the electricity activity back to 0 until the factor is available.
