The customer portal is linked with various electricity and water meters located in the buildings of the “self-consumption community”. The vast amount of data collected is automatically evaluated on the customer portal in real-time. The user then gets easy access to this data in the form of interactive diagrams.

The simple and user-friendly customer portal is the centrepiece of our solution. It allows the costs of electricity, heating and water to be separated and billed in a very simple way that saves time and does not require expert knowledge.

New utility bills

Up until now, billing for electricity was the job of energy companies. In “self-consumption communities”, this complex task now lies with property managers for the first time. Our aim was to actively simplify this task. That is why we developed an easy, automated utility bill on the SEL customer portal. This centrepiece of Smart Energy Link’s solution is simple, user-friendly and has been developed using the latest technologies, such as Python and Vue.js. It is based on the vast volume of data continuously supplied to us by the meters. The complex calculations surrounding electricity tariff models are processed in the background. With just a few clicks, you have a simple, transparent and user-friendly utility bill for the amount of sustainable electricity used.

Make complex tasks easy with the right service design, a tailored user experience and an agile team

Our biggest challenge was making the complex topic of electricity in “self-consumption communities” easy for users. We were working in a field that was completely new for all those involved, so continuous learning and trying new approaches was a popular way of working. The key to success for this project was taking a customer-oriented approach to creating the service design and user experience and the agile scrum method when executing the project.

Using the latest technologies to create an exciting user experience

Smart Energy Link’s specific needs were fulfilled by developing customised solutions in Python and Javascript. The system architecture has been designed on the principles of flexibility and expandability. The widespread availability of the Django framework in the Python world and the ease with which robust and performant web applications can be created with it were decisive reasons for choosing this framework for the back end. This choice of technology allowed for the implementation of a future-proof, performant and open solution that can be developed and operated cost effectively. At the same time, this also laid the foundations for further developments that had already been planned.
