Advancing Investment Grade Thinking in Ontario’s Energy System – Mapping Stranded Load in Ontario

Understanding Where Demand Is Approved — But Power Is Not

Ontario is already experiencing material volumes of approved but unserved electricity demand. Yet, there is no shared, system-wide view of how much load is stranded, where it is geographically concentrated, and — most importantly — why it is stranded. This session uses real planning region and infrastructure data to examine the interaction between generation, transmission, distribution, and fuel networks, supported by live system visibility tools such as GridWatch.

Why this matters now

Political and economic strategies assume accelerated electrification and growth. Without a quantified view of stranded load, capital is misallocated and system risk compounds silently.

Working Problem

What is the comprehensive estimate of stranded load by region and voltage class, and what proportion is driven by transmission limits, distribution constraints, regulatory delay, or supply shortfall?

Session Outcome

An evidence-based map of investment priority and a common analytical language for growth-enabling infrastructure.
