Welcome — and thank you for being part of Ontario’s energy community.
This wiki is a shared knowledge base designed to help participants in the Ontario energy sector understand how the system works as a whole: who the players are, how they interact, what the rules mean in practice, and why the market operates the way it does.
Whether you are a new entrant learning foundational concepts or an experienced professional expanding beyond your specialization, this resource is meant to support you.
Ontario’s energy system is sophisticated, highly regulated, and deeply interconnected.
It includes electricity, natural gas, policy, markets, reliability operations, environmental obligations, and long-term planning — all governed by multiple organizations with distinct mandates.
New participants often encounter challenges such as:
This wiki bridges those gaps by organizing knowledge into a single structured learning path — from fundamentals to expert-level detail.
Start here if you are new to the sector.
Clear descriptions of who does what — and how responsibilities differ.
You will learn:
From high-level to detailed operational understanding.
Topics include:
Understand how requirements actually work in practice.
A continuously expanding reference to decode industry language quickly.
You can navigate in three ways:
New to the sector?
Start with Foundations → System Overview
Trying to understand a process?
Go to Organizations & Roles then follow linked workflows
Need a quick reference?
Use the Glossary & Acronyms
Each page links both upward (big picture) and downward (technical detail) so you can explore at your own depth.
This resource supports people across the energy ecosystem:
No prior sector experience is assumed.
This project follows a few simple principles:
Clarity over jargon
We explain what something means before explaining how it works.
System perspective
Pages emphasize how parts interact, not just isolated responsibilities.
Progressive depth
Every topic moves from conceptual → operational → technical.
Neutral & factual
This is an educational resource, not an advocacy document.
The Ontario energy sector evolves continuously — new market designs, planning frameworks, and regulatory decisions reshape how participants operate.
This wiki is designed to grow with the sector.
If you notice gaps, unclear explanations, or areas that need expansion, contributions and improvements are encouraged.
This wiki is an educational guide intended to aid understanding.
It does not replace official rules, regulations, contracts, or regulatory guidance.
Where differences exist, official sources always prevail.
Begin with:
→ System Overview (Fundamentals)
From there, you can follow the structure naturally — just as professionals in the sector gradually learn:
first the concepts, then the relationships, then the mechanics.
Welcome to Ontario’s energy system.
