Head of System Planning (m/f/d)

🌱 100% fossil-free: We have been working towards this for 25 years and are driving forward projects that others consider unthinkable. Using wind, solar and green hydrogen, we generate, store and supply green energy. Our more than 1,200 employees are working on energy projects with a capacity of over 30 gigawatts worldwide.

ENERTRAG develops, builds and operates energy solutions using wind, photovoltaics and green hydrogen to drive the energy transition forward worldwide – and to completely replace fossil fuels in the energy supply.

👉 Join our team in Berlin or Dauerthal as Head of System Planning (m/f/d) and work with us on our mission: to generate sustainable renewable energy. So that the Earth remains a place worth living in.

• You will take on the technical and managerial leadership of the System Planning team and be responsible for setting objectives, prioritisation, resource planning, and the individual development of your staff. 
• You will ensure high-performing and well-coordinated cross-team collaboration through clear lines of responsibility, regular feedback, and the continuous improvement of working methods and processes. 
• You will oversee the further development and quality assurance of databases, modelling standards and methodological frameworks for renewable energy, battery storage, electrolysis, and Power-to-X systems. 
• You will carry out the techno-economic modelling and optimisation of integrated energy systems comprising wind, photovoltaics, battery storage, electrolysers and hydrogen storage, and critically review the results. 
• You will analyse and optimise hybrid energy projects and colocation concepts in terms of development, curtailment volumes and the prioritisation of plant utilisation behind the grid connection point (GCP), considering technical, economic and regulatory framework conditions. 
• You will prepare the results of the modelling as well-founded recommendations for action and a basis for decision-making, and coordinate collaboration with project development, grid planning, engineering, commercial and finance. 
• You will support and manage system planning for international projects in Germany, South Africa, Namibia and Spain, considering the respective country-specific conditions. 

• A Master’s degree in Energy Engineering, Electrical Engineering, Industrial Engineering, Mathematics, Physics or a comparable quantitative discipline forms your technical foundation, whilst a PhD would be an advantage. 
• You have at least five years’ relevant professional experience in energy system modelling, in the field of renewable energies, battery storage or Power-to-X, as well as demonstrable experience in leading technical teams or workstreams. 
• You possess in-depth knowledge of the simulation and mathematical optimisation of energy systems, particularly in time-based modelling and capacity optimisation. 
• You are distinguished by your excellent practical knowledge of Python and experience in testing and validating models and programme code, whilst knowledge of open-source energy modelling tools like PyPSA is an advantage" 
• Your profile includes a good understanding of electricity markets, grid connection conditions, the marketing of renewable energies, and the economic evaluation of energy systems, for example using CAPEX, OPEX, NPV and IRR. 
• You are characterised by a structured and independent approach to work, strong organisational and communication skills, as well as assertiveness and a passion for collaborating with different specialist departments; this is complemented by excellent German and business-level English.
