The Danish Transmission System Operator (TSO) needed an expert assessment, recommendations and guidelines for how to proceed the development of DataHub 3.0, at scale.

In brief
In brief


DataHub 3.0 was planned to launch in Q4 2022, but the project was delayed. The main reason for the delay was to be found in initial low organizational maturity. This maturity was reflected in two decisive factors. Firstly, the scope and business complexity of the task in relation to IT development turned out to be significantly higher than expected, which was the primary reason for the delay. Secondly, the transition to becoming an IT development organization was a significant change.


Multitrack investigations combining qualitative and quantitative analyses. Documentation and systems access. Reusable items were analysed. Recommendations for achieving the goal based on the current situation.

Halfspace's contribution

Halfspace's assessment and report gave clear guidance for the further development of Datahub 3.0. As a result, direction was provided towards a more focused organization as well as confirmation of the chosen path for the platform.

A word from our client

The backbone of the danish digital energy infrastructure

The Danish DataHub facilitates and automates the execution of market processes and business transactions in the Danish energy retail market. Meter readings from approx. 3.3 million metering points (consumption and production) are registered and managed in the DataHub system for settlement purposes. The purpose of DataHub is to ensure uniform communication methods and standardized processes for professional participants in the electricity market in order to stimulate competition and optimize market conditions for electricity consumers. In 2019 the work for a new DataHub 3.0 started. The vision was to create a platform with high reliability, scalability and flexibility.

A Clear path

To continue driving the vision the organization Energinet DataHub needed some stronger insights and guidelines regarding the reusability of what had already been developed, and alignment on the future development of DataHub 3.0. They engaged with a team of expert advisors and senior engineers from Halfspace to conduct a full assessment and recommendation report. The report contained essential evaluations and recommendations that could push the progress forward. Through heavy stakeholder involvement and a deep technical review, the team evaluated the current state of DataHub 3.0.

Future proof

Based on the assessment, guidelines were developed that would future-proof DataHub 3.0 and ensure a scalable, reliable and flexible solution, ensuring uniform communication methods and processes for all Danish electricity market professionals. All with the purpose of stimulating competition and optimising market conditions for electricity consumers.


Before implementing complicated technological solutions, it is important to identify potential pitfalls and areas of vulnerability unique to the context at hand. With a thorough risk assessment at hand, a clear strategy with detailed guidelines can be created. When dealing with data foundations, it is important to expand the context to not only assess the technical foundation, but also the organizational ecosystem around the foundation.
