Trondheim Symposium 2025SYMPOSIUM VENUE


Trondheim is the 3rd largest city of Norway. The university NTNU together with the SINTEF research institute leads the world in many technology-based research areas. Nidaros Cathedral is one of Trondheim's most famous tourist attractions and is worth a visit.

The venue for the Symposium will be Clarion Hotel Trondheim. 19 meeting rooms - with a capacity of 1800 participants for the largest one – make Clarion Hotel one of Scandinavia's largest convention centers. Discover the view on the fjord, enjoy the modern Nordic design and the vibrant atmosphere.




Participants wishing to present and publish papers should submit synopses by following the instructions on https://cigrenrccsymposium2025.com/, where the synopses and paper templates are also available. All synopses, papers, and presentations must be in English. Please note that at least one author should present the paper at the symposium.
