Organization & context:

Within the Short-term Power as-a-Service (SPaaS) platform of GEM,S the Power Day-ahead (PDA) desk supports a large range of internal and external customers in Central Western Europe (CWE) by providing power asset optimization services.

PDA aims at delivering spot value for power plants. To achieve its purpose, the team is accountable for:
•Carrying out daily (7/7) optimization runs for the portfolio of assets in scope (nuclear, thermal, CHP, renewable and pump storage assets) and devising a bidding strategy on the day-ahead exchanges of CWE that maximizes revenue while ensuring physical balance.

• Steering the short term (intra-month) production and maintenance planning of the assets, acting as the single point of contact towards local production sites, internal and external stakeholders.

Role description:

•Simplification and digitalization (automation) of the desk activities by upgrading (or replacing) the existing VBA codes with server-side Python scripts where relevant.
•P&L reporting on day-ahead bidding activities (spot and ancillary) and contributions to the platform-wide reporting on Short-term results.

•A structured and analytical personality with a hands-on and positive attitude.
•An understanding of energy markets and the economics behind power plants, their technologies and how they are exploited in European power markets.
•Proficiency in Python. Experience in machine-learning techniques are considered an important added value.
•Resilience to stress and interest in taking part in a rotating, on-duty shift system (7/7).
