Energy & Tax Attributes
:::tip Entity ID tip
<home_name> is a placeholder for your Tibber home display name in Home Assistant. Entity IDs are derived from the displayed name (localized), so the exact slug may differ. Can't find a sensor? Use the Entity Reference (All Languages) to search by name in your language.
:::
Most price sensors include energy price and tax attributes that break down the total price into its components:
Show formula
total = energy_price + tax
These attributes appear on all price sensors that display a raw price (not on percentage, level, or trend sensors). The energy_price is the raw spot/market price, while tax includes all fees, surcharges, and taxes added by your electricity provider.
:::note Transition After Update
After updating the integration, the energy_price and tax attributes will appear gradually as new price data is fetched from the Tibber API. Existing cached intervals (up to ~2 days old) won't have these fields yet — the attributes will simply be absent until fresh data replaces them. No action needed.

Where These Attributes Appear
| Sensor Type | energy_price |
tax |
Notes |
|---|---|---|---|
| Current/Next/Previous Interval Price | ✅ | ✅ | Single interval values |
| Rolling Hour Average | ✅ | ✅ | Averaged across 5 intervals |
| Daily Min/Max/Average | ✅ | ✅ | Aggregated for the day |
| Trailing/Leading 24h | ✅ | ✅ | Aggregated across window |
| Future Average (N-hour) | ✅ | ✅ | Averaged across future window |
| Levels, Ratings, Trends | ❌ | ❌ | Not price sensors |
| Volatility | ❌ | ❌ | Statistical, not price |
Use Cases
Solar Feed-In & Net Metering (Saldering)
In countries like the Netherlands, solar feed-in compensation is based on the raw energy/spot price, not the total consumer price. The energy_price attribute gives you exactly this value — no more reverse-engineering from the total price with fragile template calculations.
Show YAML: Solar Feed-In and Net Metering
# Example: Decide whether to export solar power or consume it
# Compare energy price (what you'd earn by exporting) vs. total price (what you'd pay)
automation:
- alias: "Solar: Export or Consume"

{% set total = states('sensor.<home_name>_current_electricity_price') | float %}
{# Export when energy price is high relative to total — you earn more #}
{{ energy is not none and energy > (total * 0.4) }}

Price Composition Analysis
Understand how your electricity price is structured — useful for comparing across days or spotting trends in market prices vs. fees:
Show YAML: Price Composition Analysis
# Template sensor showing tax share
template:
- sensor:
- name: "Electricity Tax Share"
unit_of_measurement: "%"
state: >
{% set tax = state_attr('sensor.<home_name>_current_electricity_price', 'tax') %}
{% set total = states('sensor.<home_name>_current_electricity_price') | float %}
{% if tax is not none and total > 0 %}
{{ ((tax / total) * 100) | round(1) }}
{% else %}
unavailable
{% endif %}

Country-Specific Calculations
The composition of the tax field varies by country (Norway, Sweden, Germany, Netherlands each have different fee structures). For detailed examples of how to build country-specific calculations using input_number helpers and template sensors — including Dutch solar feed-in compensation (saldering) — see the Community Examples page.
In Chart Data Actions
The energy_price and tax fields are also available in the get_chartdata action. See Chart Actions — Energy & Tax Fields for details.
