2027 Event Agenda

Hydro One implemented a Real-Time Load Transfer Study (RTLTS) capability within its 
Schneider Electric EcoStruxture Advanced Distribution Management System (ADMS) to 
modernize outage response and improve operational decision-making.

Historically, load transfer studies were conducted offline by Planning using non-DMS tools 
and based on typical system configurations rather than actual system conditions.  
While effective for planning, this approach was not suitable for real-time operations during 
unplanned outages, where conditions are dynamic and decisions must be made quickly.  
As a result, opportunities to keep customers energized or minimize outage duration were 
limited, and operators relied heavily on a small number of specialists.

The RTLTS initiative transformed load transfer studies into a real-time, operator-driven 
capability using live system data within ADMS. By embedding standardized workflows 
directly into the control room environment, operators can now safely and consistently assess 
transfer options during active outage conditions without relying on external tools.

This innovation has significantly improved operational performance and customer outcomes. 
Operators can make faster, more accurate restoration decisions, reducing outage duration 
and increasing confidence across all shifts. The approach has also strengthened resiliency 
by reducing dependency on specialized resources.

The results are measurable. In 2025, Hydro One avoided 40.14 million Customer Minutes 
Interrupted (CMI) and reduced Distribution SAIDI by 27.11 minutes. In 2026 year-to-date, 
88.14 million CMI have been avoided, with a 59.52-minute reduction in SAIDI.

This scalable solution demonstrates how utilities can leverage existing ADMS platforms to 
unlock real-time operational value, improve reliability performance, and deliver meaningful 
benefits to customers while maintaining the highest safety standards.
