Abstract
The aim of reducing carbon emissions through the digitization of the energy sector involves several challenges. One potential solution is the integration of renewable energy sources; however, the volatile and intermittent nature of this type of energy requires precise forecasting. This paper presents a novel, intelligent information system that covers the entire data lifecycle in the energy sector, including data acquisition, processing and storage, model development and training, and a user-friendly web application. The system was tested in three real-life use cases and demonstrated effectiveness and versatility in addressing the intricate data challenges faced by the energy industry. The paper concludes with suggestions for further research in this area.
