Project description
You will join the development of an advanced digital twin platform for the energy transition, designed to unify energy and climate-related data into a single, comprehensive solution.
The platform supports stakeholders involved in energy transformation by providing data-driven insights and decision-making tools. It addresses key challenges such as CO₂ balancing, renewable energy expansion, power grid planning, and municipal heating strategies.
Built on a modular and scalable architecture, the solution enables complex analytics and supports real-time insights in a rapidly evolving energy sector.
