Iqony validates its transformation plans with Gradyent's Digital Twin

Iqony Fernwärme, part of the Steag Iqony Group is aiming to strategically expand its district heating supply and its decentralised generation structure. To achieve this, the company is relying on Digital Twin technology.

The company has developed advanced static planning capabilities in STANET that can be complemented with thermohydraulic calculations Gradyent’s Digital Twin delivers. The first step in this direction for the company was to look for a solution that would demonstrate the current state of its Essen-Süd district heating system as well as the target network simulation for expansion planned for 2035 and 2045.

“We have recognised early on that our transformation plans can only be achieved by building a solid, data-driven foundation for target planning. We chose the Digital Twin technology because it operates based on historical operational data and thermohydraulic data, opening the door to high-resolution simulations for the complex Essen Süd grid. Gradyent made a good impression on us from both technical and personnel perspective.”

Simulating scenarios of future network expansion

Gradyent’s Digital Twin solution is based on the network topology (GIS system) with geographical information, weather and sensor data, physics-based thermohydraulic models and machine learning. This enables simulations based on the current, real network behavior, reducing risks in the design and commissioning of system technology that could reduce up to 20% of CAPEX.

Iqony will use the Digital Twin to simulate several scenarios such as the identification of thermohydraulic bottlenecks, analysing the possibility of reducing the flow temperature and temperature difference as well as calculating the additional pump power required to maintain these conditions.

In addition, measures will be investigated that either improve the previously identified potential or significantly reduce the additional energy consumption of the pumps. Finally, the optimal feed-in points for additional/future heat sources will be determined, with which the growing demand can be covered by new grid connections.

“We are proud to support Iqony on its mission and help the company embrace the transformative power of Digital Twin technology, bringing transparency across the entire system. This approach will help Iqony create the flexibility needed to adapt and thrive in a rapidly evolving district heating landscape.”
