Center Denmark
Overview
Center Denmark is located in Fredericia, Denmark, and serves as a national hub for digitalization across the utility sector. As a TEF Site in the CitCom.ai project, Center Denmark focuses on enabling AI-driven innovation by providing access to high-quality, real-world data from electricity, water, and heating systems (including gas and PtX where relevant).
Center Denmark provides secure and structured data infrastructure that supports collaboration between utilities, AI innovators, and researchers. The site plays a central role in bridging the gap between data availability and AI application by making validated utility datasets accessible for development, testing, and scaling of smart solutions that support the green transition.
In short: Center Denmark provides access to high-quality utility data through a dedicated data portal, offering both downloadable datasets and API-based access – ready for use in AI, analytics, and research.
Services Offered
The following services provided by Center Denmark as part of the CitCom.ai ecosystem are focused on enabling secure, structured, and value-driven access to utility data. Whether for collaboration between utilities and service providers, academic research, or early-stage experimentation, the services make it possible to work with real-world data from electricity, water, heating, gas, and PtX – all compliant with GDPR and tailored to different needs.
Available Services and Example Datasets
Center Denmark builds customised datasets based on specific needs and can also provide predefined datasets for common use cases.
To create tailored datasets, the platform combines a wide range of trusted data sources from utilities and public registers, ensuring they are structured, cleaned, and ready for use in AI training, research, forecasting, or infrastructure planning.
In addition to customised datasets, Center Denmark offers predefined datasets representing some of the most frequently requested data domains:
- District Heating Data – time-series consumption and production data, typically aggregated to daily values.
- Water Data – metered water consumption datasets, supporting both operational and analytical applications.
- Electricity Data – household or aggregated consumption data, enabling load analysis, forecasting, and optimization use cases.
A full overview of available data sources and datasets can be explored via portal.centerdenmark.com or in the Data Catalouge.
Service 1: Access to Utility Data for Co-developed Digital Services
This service supports collaboration between utility companies and service providers by granting access to structured and enriched utility data. The data is typically used for AI and analytics purposes such as forecasting, predictive maintenance, or grid planning.
Center Denmark manages the entire data process – from collection and cleansing to enrichment and delivery – ensuring high data quality and full GDPR compliance.

Service 2: Build-Your-Own Utility Dataset
This modular service enables data consumers (e.g. researchers, startups) to configure and request customized datasets based on available utility data.
Users select a base dataset (electricity, water, heating) and can combine it with open data sources such as weather data, building information (BBR), electricity spot prices, or demographic data. The final dataset is delivered at the desired processing level (e.g. anonymised or pseudonymised), and pricing depends on the complexity and scope of the request.

Service 3: Open Utility Datasets
This service provides free access to pre-approved, anonymised datasets via Center Denmark’s data portal.
It is designed for early-stage experimentation, prototyping, education, and exploratory analysis. The datasets are ready to use and can be combined with publicly available data sources such as weather and building data, without any need for customization.

Infrastructure Components
- Data Platforms: Data is available from Center Denmark’s secure data platform, providing structured, GDPR-compliant datasets from utilities and public sources. Data can be accessed via RESTful APIs or by downloading datasets through the Data Portal (portal.centerdenmark.com).
- Local Digital Twins: Center Denmark does not deliver a digital twin itself but provides the data infrastructure and standardized interfaces (aligned with Smart Data Models format) that enable third parties to build digital twins on top of the platform.
- Specific Hardware: No physical sensors or field devices are operated directly by Center Denmark. Data is sourced from utility partners’ smart meters, SCADA/SRO systems, and IoT devices. High-performance compute resources and secure servers are used for data ingestion, processing, and structuring.
- IoT Platforms: Data streams from IoT sources, such as smart meters, SCADA systems, weather stations, and building sensors, are securely integrated via partner-provided connections and standardized for use on the platform.
- Visualization Platforms: Visualization is primarily based on open-source tools such as Apache Superset, offering flexible dashboards and analytics. The platform also supports integration with Power BI and other external visualization environments as needed.

Available Data Sources
Since Center Denmark builds customised datasets based on specific needs, there are no predefined or fixed datasets available.
Instead, the platform provides access to a wide range of trusted data sources from both utilities and public registers. These sources can be combined and processed to create datasets tailored to individual use cases – whether for AI training, research, forecasting, or infrastructure planning.
The full overview of available data sources and formats can be explored at portal.centerdenmark.com.
