European Utility Week | © Landis+Gyr | November 5, 2014 Case DONG Energy, Denmark 8 Increased load factor to 80% SAIDI decreased from 35 min to 7 min Improved Network Planning and reduced CAPEX investments (by up to 70%) Improved fault location and restauration Solution delivery 330 LV and MV Monitoring and Control Systems RTU’s Sensors Communication Outcome DONG wanted to improve their operational awareness of the network, reduce SAIDI and postpone capital expenditure. The solution was extended to LV monitoring in order to have visibility on potential network issues following the renewable energy production.
