## Country-Specific Price Calculations
|
||||
|
||||
The Tibber API provides the raw spot price (`energy_price` attribute, in ct/kWh) and tax/fee component (`tax` attribute) on every price sensor. Since the exact composition of `tax` varies by country, you can use these attributes to build **your own** country-specific calculations with Home Assistant templates.
|
||||
The Tibber API provides the raw spot price (`energy_price` attribute) and tax/fee component (`tax` attribute) on every price sensor. Their unit follows your integration's **Currency Display Mode**:
|
||||
|
||||
- Subunit mode: `ct/kWh` (default for EUR, including NL)
|
||||
- Base mode: `€/kWh`
|
||||
|
||||
Since the exact composition of `tax` varies by country, you can use these attributes to build **your own** country-specific calculations with Home Assistant templates.
|
||||
|
||||
:::tip Keep templates unit-safe
|
||||
For long-term stable templates, normalize values to `€/kWh` inside your template (recommended below). If you use Subunit mode, you can alternatively use the dedicated **Current Electricity Price (Energy Dashboard)** sensor (`current_interval_price_base`), which provides base-currency values for Energy Dashboard use cases. In Base mode, this extra sensor is not exposed because `current_interval_price` already provides base-currency values.
|
||||
:::
|
||||
|
||||
:::tip Why templates instead of built-in calculations?
|
||||
Tax rates and energy fees change regularly (often annually). Using `input_number` helpers in Home Assistant keeps your calculations up-to-date with a simple UI adjustment — no integration update needed.

## 🇩🇪 Germany: Price Composition
|
||||
## 🇩🇪 Germany: Feed-In Compensation
|
||||
|
||||
### Background
|
||||
|
||||
In Germany, the electricity price includes numerous components bundled into `tax`:
|
||||
In Germany, private households usually get a **fixed feed-in compensation** (Einspeisevergütung) for exported PV energy, while consumption uses the dynamic end-user price from your tariff.
|
||||
|
||||
| Component | German Name | Description |
|
||||
|-----------|-----------|-------------|
|
||||
| Spot price | Börsenstrompreis | Variable in ct/kWh (= `energy_price` attribute, divide by 100 for €/kWh) |
|
||||
| Grid fees | Netzentgelte | Varies by grid operator |
|
||||
| Electricity tax | Stromsteuer | Fixed per kWh |
|
||||
| Concession fee | Konzessionsabgabe | Varies by municipality |
|
||||
| Surcharges | Umlagen (§19, Offshore, KWKG) | Various regulatory surcharges |
|
||||
| VAT | Mehrwertsteuer | 19% |
|
||||
That means the practical question is often:
|
||||
|
||||
### Template: Spot Price Share
|
||||
- consume/store energy locally now, or
|
||||
- export now at your fixed feed-in rate
|
||||
|
||||
A simple template sensor showing what percentage of your total price is the actual energy cost:
|
||||
### Step 1: Create Input Number Helper for Feed-In Compensation
|
||||
|
||||
Create one helper for your current contractual feed-in rate in `€/kWh`.
|
||||
|
||||
**Settings → Devices & Services → Helpers → Create Helper → Number**
|
||||
|
||||
| Helper | Entity ID | Min | Max | Step | Unit | Example Value |
|
||||
|--------|-----------|-----|-----|------|------|---------------|
|
||||
| Einspeisevergütung | `input_number.einspeiseverguetung` | 0 | 1 | 0.0001 | €/kWh | 0.0778 |
|
||||
|
||||
:::note Keep this value up to date
|
||||
Use the exact value from your contract or network operator statement. Typical values differ by commissioning date and plant setup (partial vs full feed-in).

### Step 2: Template Sensors for Feed-In Decision Support
|
||||
|
||||
These sensors normalize your current price to `€/kWh`, compare it with your fixed feed-in compensation, and expose a clean binary signal for automations.
|
||||
|
||||
:::note Display-mode safe
|
||||
`current_electricity_price` can be in `ct/kWh` or `€/kWh` depending on display mode. The template below normalizes automatically to `€/kWh`.
