Lighten Net Congestion with the Open Source Transformer Thermal Model

Event Recap: FOSDEM 2026 TL;DR At FOSDEM 2026, Imke de Man and Harm van Leijen presented the open source Transformer Thermal Model. The session explored how modeling transformer hotspot and oil temperatures can help grid operators better understand transformer loading limits, identify acceptable operating conditions, and support efforts to address grid congestion. Watch the presentation Addressing Grid Congestion The speakers opened by discussing grid congestion in the Netherlands and the need…
