Integrate electricity data from Energinet Denmark

Denmark’s electricity DataHub is managed by Energinet – the Danish transmission system operator (TSO). Ento is an approved third-party provider to the platform, and therefore, Danish businesses and public organisations can grant access to all their buildings’ data with just a few clicks. If you’re looking at optimising your energy consumption with Ento, the DataHub is always the place we recommend starting.

Q:

What does it cost to get access to data?

A:

This integration is free of charge as it utilises existing meters installed for billing purposes.

Q:

How can I use the data to create value for my organisation?

A:

The DataHub gives up to 4 years of historical data on hourly intervals and daily updated meter readings. This data is ideal for energy optimisation using Ento Advisor as well as developing a comprehensive, long-term energy strategy and ESG reporting through Ento Strategy.

Q:

What is the data suited for?

A:

Q:

How do I get access to the data?

A:

The designated individual within your organisation, equipped with a MitID Erhverv digital ID for the relevant CVR number(s) covering your electricity contract and thereby your meter(s), needs to log in to ElOverblik and grant access to the appropriate meters for a specified period. Ento’s API will then retrieve the data and allocate it to your buildings automatically. We recommend requesting three years of historical data for a comprehensive analysis.

Integrate district heating and water data from local utilities in Denmark

Denmark has more than 350 district heating utilities and more than 2,000 water utilities. Ento can integrate with all utilities who have remotely-read meters with an hourly frequency e.g. via Secure File Transfer Protocol (SFTP) or Application Programming Interface (API) integrations. Ento manages the data integrations and pricing information for each local utility to automatically and instantly find the most relevant buildings to optimise – e.g. by reducing return temperatures in the district heating system or identifying water leaks based on usage patterns.

Q:

What does it cost to get access to data?

A:

While most integrations are free or at a low fixed cost, as they are using existing metering equipment, some utilities (e.g. HOFOR) or metering providers (e.g. Diehl) charge integration fees.

Q:

How can I use the data to create value for my organisation?

A:

Most district heating and water utilities in Denmark are able to send hourly interval data. This data is ideal for energy optimisation using Ento’s District Heating Advisor and Water Advisor as well as developing a comprehensive, long-term energy strategy and ESG reporting through Ento Strategy.

Some district heating and water utilities are only able to send daily interval data. This data can also be used in Ento Advisor, but not with the same granularity and insight in the automated analysis.

Q:

What is the data suited for?

A:

Q:

How do I get access to the data?

A:

In Denmark, most main meters with hourly resolution are from Kamstrup, Diehl Metering, or KMD EnergyKey. The integrations send data to Ento servers via SFTPs:

  • Kamstrup READy: For new utility integrations, Ento arranges an online screen share session, guiding the utility step-by-step through the data-sharing process. This takes about 20 minutes and requires no prior preparation for the utility. After this, the utility can easily follow the integration guide. Kamstrup READy is the best SFTP integration for hourly data from main meters in Denmark as they send data free of charge with relevant units, addresses and historical data. 
  • Diehl: The utility and customer must inform Diehl of the end customer’s consent to cover Diehl’s integration fees. Upon confirmation, Diehl will send data to Ento. Currently, Diehl does not provide historical data although the data is available. Diehl is working on a solution to provide this service to their customers. 
  • KMD EnergyKey: Several of the largest utilities in Denmark use KMD’s EnergyKey. When Ento requests the data from these utilities, they typically have to pass on the information to request KMD to set up the integration. Integration time ranges from a couple of weeks to a couple of months. KMD EnergyKey does not send addresses at the moment. This is a feature request by the utilities. Either the utilities themselves or the customers of the utilities have to find the addresses and send them to Ento so they can be manually set up in the integration. 
Integrate gas data from utilities in Denmark

Denmark is making significant strides toward renewable energy sources to reduce dependency on natural gas. The utility crisis of 2022, marked by soaring gas prices, led to increases in electricity and district heating costs, driving an accelerated shift in the country's energy landscape. This transition is shaping the operations and strategies of Danish gas utilities and impacting customers reliant on gas. As a result, Danish consumers are actively seeking insights into their gas consumption to facilitate a smoother transition, such as shifting from gas to district heating. Access to gas data is key to understanding consumption patterns and planning an effective conversion. However, unlike other utilities, gas data is often less granular, typically available on a monthly or quarterly basis. Nonetheless, access to the gas data empowers customers in their energy transition.

Q:

What does it cost to get access to data?

A:

Access to gas data is free of charge.

Q:

How can I use the data to create value for my organisation?

A:

This data is ideal for energy optimisation using Ento’s Gas Advisor as well as developing a comprehensive, long-term energy strategy and ESG reporting through Ento Strategy

Q:

What is the data suited for?

A:

Q:

How do I get access to the data?

A:

Two of the top providers of gas data are Energi Danmark and Evida’s Gas Datahub.

  • Energi Danmark: Ento will send a digital consent form for your signature. Once signed, it will be sent with your meter list to Energi Danmark for SFTP integration.
  • Evida’s Gas Datahub: Ento generates a request link for you. Log in using your MitID Erhverv for the relevant CVR number to grant data access. Once approved, Ento can view the data for the consented period. Be aware that this service is only available for consumption over about 300,000 m3 according to Evida.
Live HVAC control and energy data integration with Danfoss Leanheat

Danfoss is a technology provider that most Danish building owners have equipment from – e.g. a thermostat on the radiator or an electronic controller (ECL). Ento integrates with the online platform Danfoss Leanheat Monitor. The platform can be used to collect data from energy meters connected to each ECL, but also to write back to the controllers to provide fully autonomous Heating, Ventilation and Air Conditioning (HVAC) management using Ento Control.

Q:

What does it cost to get access to data?

A:

If you already have a Danfoss Leanheat setup, the integration is free of charge. If not, installing an ECL is a relatively cost-effective way of controlling a building. Danfoss Leanheat Monitor enables remote control of each controller.

Q:

How can I use the data to create value for my organisation?

A:

This integration enables intelligent HVAC management using Ento Control, energy optimisation through Ento Advisor, and supports the development of a comprehensive, long-term energy strategy and ESG reporting through Ento Strategy.

Q:

A:

Simply log into Danfoss Leanheat Monitor and send an invitation to Ento as an external user. Ento will set up an API token that can be used to remotely read the meters and write back to the controllers based on your setpoint on the Ento Platform.

Live data from sub-metering providers for electricity, heating, and water

Many large building owners in Denmark have installed sub-metering solutions from different technology providers such as MUC.EASY, IQ Energy (Eniscope), Elektrokom or DanTaet. Ento does not provide this hardware but supports integrations using common protocols such as SFTP or API. In this way, the building owner takes ownership of the hardware and is not dependent on a certain provider.

Q:

What does it cost to get access to data?

A:

Accessing and sharing data from sub-metering providers can either be free of charge or cost an annual subscription fee to the technology provider.

Q:

How can I use the data to create value for my organisation?

A:

Integrating energy data from sub-meters enables energy optimisation with Ento Advisor, and supports the development of a comprehensive, long-term energy strategy and ESG reporting through Ento Strategy.

Q:

What is the data suited for?

A:

Q:

How do I get access to the data?

A:

If you already have sub-metering installed, ask your sub-metering provider how to export data to Ento. Setting up an SFTP server takes a few minutes for us, so this is an ideal way of testing a data connection from your existing hardware.

Indoor air quality data integration for real-time insights

Indoor air quality data (IAQ) from other technology providers can also be integrated into Ento. 

Q:

What does it cost to get access to data?
