%description
Advanced forecasting algorithms for long-term energy demand at the
national or regional level. The methodology is based on Grandón et al.
(2024) <doi:10.1016/j.apenergy.2023.122249>; Zimmermann & Ziel (2024)
<doi:10.1016/j.apenergy.2025.125444>. Real-time data, including power
demand, weather conditions, and macroeconomic indicators, are provided
through automated API integration with various institutions. The modular
approach maintains transparency on the various model selection processes
and encompasses the ability to be adapted to individual needs. 'oRaklE'
tries to help facilitating robust decision-making in energy management and
planning.
