Nord Pool integration for Home Assistant

Donate "Buy Me A Coffee"

Nord Pool is a service provider that operates an electricity market and power system services, including the exchange of electricity on a spot market Nordics and Baltic countries.

This integration provides the spot market (hourly) electricity prices for the Nordic, Baltic and part of Western Europe.

The Nordpool sensor provides the current price with today's and tomorrow's prices as attributes. Prices become available around 13:00.

ApexCharts card is recommended for visualization of the data in Home Assistant.

Getting started

Installation

Option 1: HACS

  • Follow Open your Home Assistant instance and open a repository inside the Home Assistant Community Store. and install it

  • Restart Home Assistant

    or

  • Go to HACS -> Integrations,

  • Select +,

  • Search for nordpool and install it,

  • Restart Home Assistant

Option 2: Manual

Download the latest release

cd YOUR_HASS_CONFIG_DIRECTORY    # same place as configuration.yaml
mkdir -p custom_components/nordpool
cd custom_components/nordpool
unzip nordpool-X.Y.Z.zip
mv nordpool-X.Y.Z/custom_components/nordpool/* .  

Usage

Configuration Variables

Configuration Required Description
Region yes Country/region to get the energy prices for. See Country/region codes below for details.
Currency no Default: local currency
Currency used to fetch the prices from the API.
Include VAT no Default: true
Add Value Added Taxes (VAT) or not.
Decimal precision no Default: 3
Energy price rounding precision.
Low price percentage no Default: 1
Percentage of average price to set the low price attribute.
IF hour_price < average * low_price_cutoff
THEN low_price = True
ELSE low_price = False
Price in cents no Default: false
Display price in cents in stead of (for example) Euros.
Energy scale no Default: kWh
Price displayed for MWh, kWh or Wh.
Additional Cost no default {{0.0|float}}
Template to specify additional cost to be added. See Additional Costs for more details.

Option 1: UI

  • Go to Settings -> Devices & Services
  • Select + Add Integration
  • Search for nordpool and select it
  • Fill in the required values and press Submit

Tip: By default, the integration will create a device with the name nordpool_<energy_scale>_<region>_<currency>_<some-numbers>. It is recommended to rename the device and all its entities to nordpool. If you need to recreate your sensor (for example, to change the additional cost), all automations and dashboards keep working.

Option 2: YAML

Set up the sensor using in configuration.yaml.

Minimal configuration:

sensor:
  - platform: nordpool
    region: "Kr.sand" 

Example configuration:

sensor:
  - platform: nordpool
    # Country/region to get the energy prices for. 
    region: "Kr.sand"
    
    # Override HA local currency used to fetch the prices from the API.
    currency: "EUR"
    
    # Add Value Added Taxes (VAT)?
    VAT: True
    
    # Energy price rounding precision.
    precision: 3
    
    # Percentage of average price to set the low price attribute
    # low_price = hour_price < average * low_price_cutoff
    low_price_cutoff: 0.95

    # Display price in cents in stead of (for example) Euros.
    price_in_cents: false

    # Price displayed for MWh, kWh or Wh
    price_type: kWh

    # Template to specify additional cost to be added to the tariff.
    # The template price is in EUR, DKK, NOK or SEK (not in cents).
    # For example: "{{ current_price * 0.19 + 0.023 | float}}" 
    additional_costs: "{{0.0|float}}"

Additional costs

The idea behind additional_costs is to allow the users to add costs related to the official price from Nordpool:

  • Add simple or complex tariffs
  • Calculate VAT

There are two special special arguments in that can be used in the template (in addition to all default from Homeassistant):

  • now(): this always refer to the current hour of the price
  • current_price: price for the current hour. This can be used for example be used to calculate your own VAT or add overhead cost.

Note: When configuring Nordpool using the UI, things like VAT and additional costs cannot be changed. If your energy supplier or region changes the additional costs or taxes on a semi-regular basis, the YAML configuration or a helper (example 4) work best.

Example 1: Overhead per kWh

Add 1,3 cents per kWh overhead cost to the current hour's price

{{ 0.013 | float }}

Example 2: Percentage (VAT)

Add 19 % VAT of the current hour's price

{{ (current_price * 0.19) | float }}

Example 3: Overhead and VAT

Add 1,3 cents per kWh overhead cost, 0.002 flat tax and 19% VAT to the current hour's price

{{ (0.013 + 0.002 + (current_price * 0.19)) | float }}

Example 4: Helper

Add 21% tax and overhead cost stored in a helper

'''{{ (current_price * 0.21) + states('input_number.additionele_kosten') | float(0) }}'''

Example 5: Seasonal peek and off-peek overhead

{% set s = {
    "hourly_fixed_cost": 0.5352,
    "winter_night": 0.265,
    "winter_day": 0.465,
    "summer_day": 0.284,
    "summer_night": 0.246,
    "cert": 0.01
}
%}
{% if now().month >= 5 and now().month < 11 %}
    {% if now().hour >= 6 and now().hour < 23 %}
        {{ s.summer_day + s.hourly_fixed_cost + s.cert | float }}
    {% else %}
        {{ s.summer_night + s.hourly_fixed_cost + s.cert|float }}
    {% endif %}
{% else %}
    {% if now().hour >= 6 and now().hour < 23 %}
        {{ s.winter_day + s.hourly_fixed_cost + s.cert | float }}
    {% else %}
        {{ s.winter_night + s.hourly_fixed_cost + s.cert | float }}
    {% endif %}
{% endif %}

One sensor per hour

By default, one sensor is created with the current energy price. The prices for other hours are stored in the attributes of this sensor. Most example code you will find uses the default one sensor option, but you can run the create_template script to create separate sensors for every hour. See the help options with python create_template --help. You can run the script on any system where Python is installed (install the required packages pyyaml and click using pip install pyyaml click)
