open data from the Danish energy system as well as data from several "living labs" and research projects

The data platform offers a user-friendly interface where it is easy to search data based on meta data, which supports the goal of open and easy access to data. has open APIs for exchanging data in real time and in "batch mode". is connected to an HPC (High Performance Computer) and to an RTDS system (Real Time System Simulation). Data can be visualized supports a wide selection of templates for this. A project can appoint a "data owner" who can create data sets and manage how this data can be accessed and by whom.

Non-profit, independent and located at the Technical University of Denmark is run and maintained by PowerLab (DTU) as non-profit and the primary target groups are researchers, students and product developers in the Energy domain. The idea is to set data free and support relevant actors in creating data-driven solutions that can contribute to the green transition.
The servers are located in Denmark, which makes storing and sharing data simpler in a GDPR context.


History has been built as part of the "Digital Energylab" project, which was completed in August 2022. You can read about the project below.



The partners support the EnergyDataDK platform through participation in the development project Digital Energy Lab at DTU. The energy sector must be able to harness the benefits of digital transformation. By developing a digital test and development platform for sustainable energy solutions, it is the partners' goal that Denmark will accelerate the development of smart energy systems for the benefit of industry and society.


PowerLabDK is a world-class experimental platform with expertise in technology development, testing, and demonstration of sustainable energy solutions.

PowerLabDK conducts research and innovation at all scales, from component-level to system-level. The platform includes flexible test laboratories, large experimental facilities, as well as urban and rural living labs, where solutions can be tested directly within the local system and in interaction with businesses and residents.

Motive for participation

It is PowerLabDK's ambition to be a driving force for cutting-edge new knowledge and innovative technologies within sustainable energy. PowerLabDK believes that digitalization is the glue that will bind the future energy system together and sees great potential in integrating the new digital platform with existing physical facilities and infrastructure to test unique solutions.

HOFOR is the utility company for the Copenhagen metropolitan area, ensuring that one million Danes have clean drinking water, providing cities with environmentally friendly district heating, city gas, and district cooling, managing wastewater, and constructing wind turbines. HOFOR also owns Amagerværket, where district heating and electricity are produced. HOFOR aims to deliver supply solutions that are green, secure, and affordable – in a way that protects groundwater, coordinates climate adaptation and storm surge protection, and provides a CO2-neutral energy supply.

Motive for participation

HOFOR District Heating, in collaboration with the project partners, aims to further develop and demonstrate new and innovative data and communication solutions based on the FlexHeat system in Nordhavn. The goal is to enable more frequent measurements of energy data and consumption for possible application throughout the rest of the city. Additionally, these solutions will be used for the development of digital models of district heating systems and to test time-dependent and more cost-effective district heating tariffs.


Bornholms Varme (BHV) produces and supplies district heating to approximately 6,500 customers in four decentralized areas on Bornholm. BHV is part of Bornholms Energi og Forsyning and actively works on green transition as part of the island's Bright Green Island vision. In the coming years, we need to transition from biomass-based heating to zero-emission solutions, and district heating must increasingly assist the electricity system through sector coupling via flexibility and other system services. The sector coupling of heat and electricity requires a new form of planning where more advanced data processing is necessary.

Motive for participation

Bornholms Varme participates to advance the digitalization of the company and prepare it for a future with intelligent control, distributed storage, sector coupling, and transition away from biomass.

SusTech logo


SusTech is a Tech Development company within the privately owned Zibra Group, which over the past 25 years has been one of the most successful Tech developers in Denmark, focusing on new technology and innovative solutions. Based on measurement data, metadata, and grid topology, SusTech will develop algorithms and visualizations of consumption in the district heating and electricity supply networks, thereby contributing to the development of models for analysis and estimation of available flexibility. Furthermore, contributing to the optimization of production based on real-time data.

Motive for participation

SusTech finds great value in developing products and services that change technical paradigms, thereby pushing the boundaries of the existing market. Through participation in the project, SusTech will have the opportunity to utilize consumer data and consumer involvement in these unique solutions. As the green transition progresses, the need for innovation and new thinking to utilize supply networks optimally increases – a development that SusTech is keen to contribute to.


The partnership in Gate 21 works to accelerate green transition and growth in Storekøbenhavn. Together with our partners, we find solutions that reduce CO2 emissions and realize energy and resource savings. Since 2009, Gate 21 has achieved strong results and with them demonstrated new, concrete paths towards green transition. In its first 10 years, Gate 21 has managed over 100 green projects worth more than one billion Danish kroner. Gate 21 has become one of Denmark's leading organizations for green transition, which, together with municipalities, regions, companies, and research, tests and develops concrete solutions for a sustainable Denmark.

Motive for participation

Gate 21 aims to contribute to making Greater Copenhagen the world's leading region for green transition and growth. The development and dissemination of energy- and resource-efficient solutions that promote green transition and growth require extensive digitization of the energy sector.

Greenlab logo


GreenLab is a green and circular industrial park, a national research center, and a technology catalyst. Here, green energy is produced, stored, converted, and shared through an intelligent network of energy and data, enabling companies in the park to share their surplus resources with each other. GreenLab is an open innovation platform and operates on a public/private partnership model, ensuring maximum benefit of knowledge, innovation, and business for all partners.

Motive for participation

GreenLab has a keen interest in developing new digital peer-to-peer solutions that can manage the internal energy infrastructure in the park. The collaboration with EnergyDataDK and Digital Energy Lab accelerates this development process.


DTU is a technical elite university with international reach and standards. Our mission is to develop and utilize natural and technical sciences for the benefit of society. We are Denmark's largest engineering education institution, and every day we work on education, research, regulatory advice, and innovation, contributing to growth and welfare.
