Energy Weather, a German company that acts as an intermediary between meteorological data and the energy market, utilizes Grafana for visualizing weather forecasts to predict energy supply and demand fluctuations. During GrafanaCon 2018, Steffen Knott and Max von Roden discussed their application of Grafana in transforming complex weather data into comprehensible visualizations that aid energy producers and grid operators. The company processes weather forecasts using C# and creates time series data that are visualized through Grafana dashboards, facilitating real-time monitoring and forecasting for renewable energy production and market prices. Energy Weather's implementation of Grafana has evolved from internal analysis to a customer-facing solution, offering about 130 user-friendly dashboards that enhance decision-making in energy generation and market planning. Despite challenges with data volume, continuous updates to Grafana and InfluxDB have improved performance, allowing the company to expand its forecasting capabilities effectively.
