Geneva, Switzerland What you'll do
The Energy Data Analyst will contribute to the digital transformation of CERN’s electricity cost modelling and load forecasting framework within the Energy & Climate Action section of the Environmental Protection group.
The role focuses on migrating legacy financial and forecasting tools to a structured Python-based analytical platform, enhancing forecasting granularity and potentially exploring AI-driven approaches for electricity load and price forecasting.
The position also involves monitoring electricity market developments and supporting CERN’s ISO 50001 energy management activities.
Your responsibilities
- Develop and consolidate a Python-based framework for electricity cost modelling, harmonising and replacing existing Excel tools used for invoice control, virtual invoicing and cost forecasting.
- Analyse electricity supply contracts and translate pricing mechanisms into structured financial simulation models.
- Contribute to CERN's load forecasting activities by analysing historical operational data, identifying consumption patterns and improving forecasting granularity from daily to hourly resolution.
- Integrate real-time data sources, including solar PV production, into forecasting and analytical tools.
- Explore and test AI and machine learning approaches for electricity load and price forecasting.
- Monitor developments in European and French electricity markets and prepare bi-monthly reports supporting procurement and risk assessment.
- Support ISO 50001 energy management activities, including documentation, audit preparation and data-driven performance monitoring.
- Contribute to cross-functional activities related to the commercial, financial and contractual follow-up of the various electricity supply agreements.
- This role includes team supervision responsibilities.
