E.ON Propojeno: A digital platform that makes electricity sharing simple in the Czech Republic
About the project
- Innovative digital platform for electricity sharing
- Easy sharing of generated electricity with point of delivery
- A solid foundation for further market development
Electricity sharing has only recently become possible in the Czech Republic. New legislation enables households and businesses, such as owners of rooftop solar PV, to share surplus electricity with selected consumption points in near real time.
E.ON was looking for a delivery partner capable of building a production-grade digital product quickly and integrating it with a complex ecosystem of internal and external systems.
Challenges
Electricity sharing entered the market without established processes, technical standards and user expectations. The solution had to translate the entire concept into a functional and understandable digital form. Key systems were at varying levels of technical maturity and often without a standard API. It was necessary to analyze integration options, define integration criteria and design a sustainable integration approach.
- A new market with low user awareness
- Incomplete infrastructure and limited APIs
- Fast time-to-market
- Enterprise integrations and operating model
Speed was also essential. The MVP had to be created within a fixed deadline so that E.ON could actively open the new market and start acquiring its first customers. The project required the design and alignment of new processes across the organization, from data work to administration to platform operation. It was not just about developing an application, but about creating a functional operating model.
Our role
Argo22 delivered the product end-to-end. From discovery and business analysis through UX/UI design and user testing, to web development and enterprise integrations.
We provided:
- Product discovery and MVP scoping
- Business analysis and process design
- UX/UI design aligned with E.ON’s evolving brand
- Prototyping and user research/testing
- Web application development
- Integrations with key internal and external systems (including systems without standard APIs)
- UAT support and launch readiness
Solution
- Digital electricity sharing platform
- Connecting the producer and the consumer
- Automation of administration and processes
- Integration into key systems
- Documentation as a "single source of truth"
- A scalable foundation for growth
E.ON Propojeno is an innovative web platform, the first of its kind in the Czech Republic. It simplifies the entire process of electricity sharing and completes the missing “customer layer” above the technical infrastructure of the market.
The key added value is the automation of steps that would otherwise entail a significant administrative burden. The connection was built from the beginning on integrations with internal and external systems (e.g. SAP, EDC, DMS, etc.). The delivery included continuously maintained documentation that unified the tasks across teams and minimized scope creep and communication noise.
The platform was designed from the beginning to handle the gradual expansion of the number of users, the involvement of other entities, and the future development of functionalities in connection with the development of the electricity sharing market.
Approach
- Discovery & MVP framing
- UX/UI & early validation
- Iterative delivery
- UAT & launch readiness
Together with the client, we defined a product strategy, key scenarios and a minimum scope that would allow for rapid validation of the new market.
During the first two months, alpha versions and prototypes were created, which underwent UX testing and set the direction for further development. This took place in sprints with continuous alignment of the product, design and technology teams and parallel preparation of integrations to key systems.
The solution was prepared for verification in a real environment, including setting up processes for long-term operation and further development of the platform.
Results & impact
Within 6 months, we delivered an MVP of a digital platform that enabled E.ON to enter the new electricity sharing market with a functional and scalable product.
- Fast time-to-market: MVP in production in 6 months (alpha version after 2 months).
- Scalable foundation for development: the solution is ready for further expansion of functions and a growing number of users.
- Connection to the E.ON ecosystem and other services: 9 integrations implemented to ensure operational functionality.
- Better customer experience: the complex process of electricity sharing was converted into a clear digital gateway.
- A result that changes the energy market: we delivered the first platform of its kind on the Czech market with the ambition of further growth and expansion.
Technologies
The platform is built on open-source technologies within E.ON’s infrastructure, avoiding vendor lock-in. A key engineering focus was designing a robust integration layer and connecting systems with varying API maturity.
List of technologies
Key takeaways
- Agile delivery is the fastest path to MVP when scope and priorities are actively managed.
- Early user testing reduces product risk and improves adoption.
- Integrations often define the critical path – strong cross-team coordination is essential.
- Living documentation speeds delivery by aligning stakeholders and reducing rework.
