Executive Summary

A challenger player in the energy trading space, with a capacity of 26GWhs storage, was looking for a tech partner to design a robust cloud infrastructure for its Energy Management System.

The goal is to support the EU’s Fit for 55 requirements by enabling large energy prosumers to store, consume and trade green energy.




Designing a complex transactive energy storage system requires a thorough understanding of market needs (green energy producers and grid operators) and combining market-specific competence with cloud and software expertise.

An energy trading system would be required to meet high resiliency and availability standards, meeting strict RPO and RTO indicators. On top of that, stringent security obligations of ISO/IEC 27001 were required, meeting full auditability & observability.

Front-end of the system is supposed to be the essential tip of the iceberg: a clean energy trading interface and battery monitoring dashboard.



In the discovery phase, Exlabs has organised an intense series of workshops for its stakeholders and business partners. During these sessions, a dictionary of terms was built, the most critical user journeys were analysed, and the requirements and scope of the MVP were defined. All this was done to ensure mutual understanding between technical architects and business and versatility in the problem field.

 An essential aspect of those sessions was the correct definition of requirements divided into functional, quality, and constraints. The latter made it possible to determine the technological stack, the shape of the cloud infrastructure, the necessary 3rd party providers offering ready-made solutions, and potential technical and expert teams. Moreover, adequately formulated constraints related to the quality requirements will let the teams monitor whether the project is going in the right direction and reaching the expected results.
Finally, Exlabs proposed the concept of AWS cloud infrastructure to the client. Since the system is intended to be highly available, it was established that it would be replicated among three data centres in the primary region. This configuration is dedicated to mission-critical systems where trivial failures, such as a lack of electricity, disk damage, or issues with the operating system, should not occur.


Along with a new partner, Exlabs has passed the discovery phase for a project intended to contribute to Europe’s energy transformation. We managed to define the requirements, which in turn contributed to the selection of technologies and solutions and the shape of teams necessary to start the development.
