Swissgrid SA, the transmission system operator of Switzerland, has embarked on a framework contract with RTE international (RTEi) to conduct comprehensive feasibility studies for a series of critical AC cable projects.
The project involves a comprehensive assessment of the feasibility of various AC cable initiatives undertaken by Swissgrid.
RTEi, a recognised authority in this field, will undertake a variety of essential tasks utilising offline simulations.
These studies encompass multiple phases, including data analysis, comprehensive modelling of the Swissgrid network, resonance and harmonic analysis, system- and equipment-level studies.
RTEi’s expertise, combined with their utilisation of EMTP (Electromagnetic Transients Programme) software, will contribute to the development of a more robust and reliable energy grid in Switzerland.

“We are truly excited and deeply grateful for the opportunity to collaborate with Swissgrid on these ambitious projects,” stated Ming Cai, power systems expert at RTEi.
“We look forward to leveraging our expertise in offline simulations to contribute to the success of this endeavor and play a pivotal role in advancing Switzerland’s energy grid towards a more robust and dependable future.”
As Switzerland’s national grid company since 2009, Swissgrid is responsible for the operation, security and development of the almost 6,700km high-voltage grid. This framework contract underscores Swissgrid’s goals to improve reliability and efficiency across this network infrastructure.
The AC contracts follow a partnership agreement between Swissgrid and RTEi, signed in November 2022, for a feasibility study and unwinding of a live optical ground wire, extending Swissgrid’s telecommunications network and installing differential protection devices to monitor overhead and underground links in the event of a fault.
