About the product

Bayernwerk, our distribution system operator in south Germany, launched the EnergieMonitor in 2018. This online dashboard displays a community’s renewables output and energy consumption in real time. The transparency provided by EnergieMonitor enables community decision-makers to take targeted action to promote the energy transition and to monitor their progress.

Way of working & technology stack

An interdisciplinary Scrum Team an average of 4 developers doing DevOps developed this product. It originated from an agency on a PoC level and was turned into a scalable and cost-effective cloud native architecture on AWS by our internal team. Next to the front-end based on Vue.js, an event-driven architecture using serverless functions with Java, together with a forecast component based on python was tied together using modern paradigms like infrastructure-as-code and CI/CD.
