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 integrationIntegrations connect and integrate Home Assistant with your devices, services, and more.

Configuration

To add the Nord Pool hub to your Home Assistant instance, use this My button:

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, it will wait a retry a few times before failing. The user can use the homeassistant.update_entity action to manually try again later, in the case the user has solved the connectivity issue.

Troubleshooting

This service is reliant on an internet connection and that the Nord Pool API is available. Here are the things you can try before raising an issue:

• Check that internet is available from your Home Assistant instance.
• Check that the Nord Pool API is available by clicking here. You should get a JSON back with the title Unauthorized.
• Use curl in a terminal on your Home Assistant instance using the same URL as previously opened in the browser. curl https://dataportal-api.nordpoolgroup.com/api/DayAheadPrices

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

Peak & off-peak sensors

Additional sensors are provided for peak and off-peak blocks.

• 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.

The block price sensors are not enabled by default.

Diagnostic sensors

Actions

Get price for date

The integration entities provide price information only for the current date. Use the “Get price for date” action to retrieve pricing information for any date within the last two months or for tomorrow.

The areas and currency parameters are optional. If omitted, the values configured in the integration will be used.

See examples how to use in a trigger template sensor.

Example action with data

action: nordpool.get_prices_for_date
data:
  config_entry: 1234567890a
  date: "2024-11-10"
  areas:
    - SE3
    - SE4
  currency: SEK

Examples

A template sensor to add VAT and fixed cost is useful to get the actual energy cost in the energy dashboard.

UI Template

Create a helper using the UI.

1. Go to 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.

template:
  - sensor:
      - name: "Nordpool"
        unit_of_measurement: "EUR/kWh"
        state_class: measurement
        state: >
          # 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 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) }}

Tomorrow’s lowest price

Using a trigger template, you can create a template sensor to calculate tomorrow’s lowest price which also puts the list of all prices in the attributes of the sensor. All prices are returned in [Currency]/MWh.

template:
  - trigger:
      - trigger: time_pattern
        minutes: /10
      - trigger: homeassistant
        event: start
    action:
      - action: nordpool.get_prices_for_date
        data:
          config_entry: 01JEDAR1YEHJ6DZ376MP24MRDG
          date: "{{ now().date() + timedelta(days=1) }}"
          areas: SE3
          currency: SEK
        response_variable: tomorrow_price
    sensor:
      - name: Tomorrow lowest price
        unique_id: se3_tomorrow_low_price
        state: >
          {% if not tomorrow_price %}
            unavailable
          {% else %}
            {% set data = namespace(prices=[]) %}
            {% for state in tomorrow_price['SE3'] %}
              {% set data.prices = data.prices + [(state.price / 1000)] %}
            {% endfor %}
            {{min(data.prices)}}
          {% endif %}
        attributes:
          data: >
            {% if not tomorrow_price %}
              []
            {% else %}
              {% set data = namespace(prices=[]) %}
              {% for state in tomorrow_price['SE3'] %}
                {% set data.prices = data.prices + [{'start':state.start, 'end':state.end, 'price': state.price/1000}] %}
              {% endfor %}
              {{data.prices}}
            {% endif %}
