**Zone**: Yellow · **Energy and farming**

## The situation

The electricity bill is high. It has many items: energy price, capacity price, grid fees. You want to know whether everything is correct.

## How it works

1. You paste the text of the bill.
2. **The Schleuse replaces secrets.** Names, addresses, identifiers and credentials are replaced with stand-in words. This happens on your side, not in the cloud. Amounts and dates stay as they are.
3. **The AI answers, the Schleuse translates back.** The answer contains the stand-in words. On your side they turn back into the real names.

## Example

**Your question to the AI:** Re-calculate this electricity bill. Do quantity and price fit together? What should I ask the supplier?

**What is in your text:**

> Bill from **Nordstrom Energie GmbH** for metering point **DE0012345678901234567890123456789**.
> Energy price 18.2 ct/kWh. Capacity price 112 EUR/kW.
> Consumption 148,000 kWh.

**What the cloud AI sees:**

> Bill from **Supplier Alpha** for metering point **MeteringPoint_1**.
> Energy price 18.2 ct/kWh. Capacity price 112 EUR/kW.
> Consumption 148,000 kWh.
