SUMO

AAR & DLR

SUMO is a state-of-the-art system rating software, developed by one of Europe's leading TSOs, that provides network-wide thermal ratings.

Case Study

Today, SUMO is extensively used across Slovenia

• Slovenia is a key nexus for north-south and east-west power flows across Europe

• SUMO was first installed in 2013 and its reach has continued to grow

• SUMO is now deployed on dozens of network elements, including 110 kV, 220 kV and 400 kV lines, power transformers, phase shifting transformers and interconnections with neighboring systems

• SUMO is used on a daily basis in Slovenian operations and in the European electricity market

• SUMO also used by system operators in Croatia and Lithuania
