The **Nord Pool** {% term integration %} integrates [Nord Pool Group](https://www.nordpoolgroup.com/) energy prices into Home Assistant.
The {% term integration %} provides the public market prices displayed on the [Nord Pool Auction page](https://data.nordpoolgroup.com/auction/day-ahead/prices).
Most European energy is traded via the Nord Pool Group marketplace. If your energy provider doesn't have a dedicated Home Assistant integration and you have a spot-price-based contract, you can use the **Nord Pool** {% term integration %}. This integration provides spot prices for your selected market, which you can, as an example, use in a {% term template %} to calculate prices for your [energy dashboard](#energy-dashboard).
{% include integrations/config_flow.md %}
{% tip %}
Only a single configuration entry is supported. Use the reconfigure option from the configuration entry if needed to modify the settings.
EUR is the base currency for market prices. If you choose another currency, you can find the conversion rate in the `Exchange rate` sensor.
All prices are displayed as `selected_currency/kWh`.

Only a single integration entry is supported. To modify the settings, you can use the reconfigure option from the integration entry.
EUR is the base currency for market prices. If you choose another currency, you can find the conversion rate in the `Exchange rate` sensor.
All prices are displayed as `[Currency]/kWh`.
{% endtip %}
## Data fetching and limitations
Data is polled from the **Nord Pool** API on an hourly basis, exactly on the hour, to ensure the price sensors are displaying the correct price.
If polling cannot happen because of no connectivity or a malfunctioning API, there is no retry; the next periodic update will try again.
## Sensors
Each market area will create a device which has the following sensors:
The integration will create entities showing today's energy prices for the configured market area. Only the base energy price is shown. VAT and other additional costs are not included.
### Main sensors
- Current price for the selected area
- Previous price for the selected area
- Next price for the selected area
| Sensor | Type | Description |
| ------------------------- | ----------------- | --------------------------------------------------------------------------------- |
| Current price | [Currency]/kWh | The current (hourly) energy price. |
| Previous price | [Currency]/kWh | The price of the previous hour. |
| Next price | [Currency]/kWh | The price of the next hour. |
| Daily average | [Currency]/kWh | The average of today's energy prices. |
These sensors can be used to calculate your current energy cost, or to help decide whether to charge the battery now or in an hour, etc.
### Peak & off-peak sensors
### Block price sensors
Additional sensors are provided for peak and off-peak blocks.
- Block average
- Block minimum
- Block maximum
- Block start time
- Block end time
- Peak refers to the price of the period from 8am to 8pm.
- Off-peak 1 refers to the price of the time period from midnight to 8am.
- Off-peak 2 refers to the average price of the time period from 8pm to midnight.

</p>
| Sensor | Type | Description |
| ------------------------------- | ----------------- | --------------------------------------------------------------------------------- |
| [peak/off-peak] highest price | [Currency]/kWh | The hightest hourly price during the given timeframe. |
| [peak/off-peak] lowest price | [Currency]/kWh | The lowest hourly price during the given timeframe. |
| [peak/off-peak] average | [Currency]/kWh | The average price of the given timeframe. |
| [peak/off-peak] time from | Datetime | The start date/time of the given timeframe. |
| [peak/off-peak] time until | Datetime | The end date/time of the given timeframe. |
These sensors show the minimum/maximum and average during certain blocks of the day. More known as off-peak (typically lower price) or peak hours (typically higher price).
The block price sensors are not enabled by default.
### Daily average
- Daily average
The daily average sensor is not enabled by default.
### Diagnostic sensors
- Last updated - indicates when the market price was last updated.
- Currency - The selected currency.
- Exchange rate - EUR is the base currency so will show the exchange rate used on the market place.
| Sensor | Type | Description |
| ------------------------- | ----------------- | --------------------------------------------------------------------------------- |
| Currency | [Currency] | The configured currency. |
| Exchange rate | Integer | The exchange rate between the configure currency and Euro's. |
| Last updated | Datetime | The time when the market prices were last updated. |
The `Exchange rate` sensor is not enabled by default.
## Examples
## Example
A template sensor to add VAT and fixed cost is useful to get the actual energy cost in the energy dashboard.
A simple template sensor to add VAT and a fixed cost from an `input_number` entity
### UI Template
Create a helper using the UI.
1. Go to {% my integrations title="**Settings** > **Devices & Services**" %} and at the top, choose the **Helpers** tab.
2. In the bottom right corner, select **Create helper**.
3. Select **Template** and **Template a sensor**.
4. Enter the fields as shown below.
The template below takes the current price attributes, adds 0.1293 EUR as fixed costs and adds 21% VAT.

### YAML Template
A template sensor to add VAT and a fixed cost from an helper entity `input_number.add_fixed_cost`.
{% raw %}
```yaml
template:
- sensor:
- name: "Full SE3 current price"
unit_of_measurement: "SEK/kWh"
- name: "Nordpool"
unit_of_measurement: "EUR/kWh"
state_class: measurement
state: >
{% set cost = states('sensor.nord pool_se3_current_price') | float(0) %}
# create a variable with the current price
{% set cost = states('sensor.nord_pool_nl_current_price') | float(0) %}
# create a variable with the additional fixed cost
{% set add_cost = states('input_number.add_fixed_cost') | float(0) %}
# Add fixed cost to the spot price and add VAT (25%)
# Add cost and additional fixed cost. Add VAT (25%) by multiplying with 1.25 and round to 2 digits:
{{ ((cost + add_cost) * 1.25) | round(2, default=0) }}
```
{% endraw %}
### Energy Dashboard
To use the Nordpool integration in the **Energy** dashboard, when configuring grid consumption and production, use the **Use an entity with current price** option.
