On July 2, 2026, Ontario’s electricity grid hit 25,864 megawatts of demand. That is a 10-year peak, tracked in real time by the Independent Electricity System Operator, the body responsible for keeping Ontario’s lights on. Average electricity prices crossed 20 cents per kilowatt-hour.
If those numbers mean nothing to you yet, that is exactly the problem this post is meant to fix.
What Is the IESO and Why Does Its Data Matter to Ontario Business Owners?
The Independent Electricity System Operator, known as the IESO, manages Ontario’s power grid in real time. It balances electricity supply and demand across the province every hour of every day, publishes live pricing and demand data, and is the authoritative source for what is happening on the Ontario grid at any given moment.
When the IESO reports a demand record, it means Ontario businesses and residents collectively pulled more electricity from the grid than they have in over a decade. That level of demand does not happen quietly. It puts pressure on the system, draws on every available generation source, and pushes real-time electricity prices up.
The IESO data is public and verifiable. Any Ontario business owner can look it up. That is what makes it meaningful. Here is their website.
Why Do Electricity Prices Rise During Peak Demand Events?
Ontario’s electricity market operates in real time. When demand spikes, grid operators need to bring additional generation online quickly. That additional generation is often more expensive to produce than baseload power. The cost of meeting that peak demand flows through to electricity pricing.
Natural gas generation is frequently what the grid leans on during peak events. When gas-fired plants run harder to meet cooling demand, natural gas prices can move upward as well. In Ontario, where many commercial operations rely on both electricity and natural gas, a sustained demand event can create pressure on both sides of an energy bill simultaneously.
A single hot day is manageable. An extended period of heat-driven peak demand is a different situation, and Europe’s experience in recent summers is a useful reference point for how long these events can run and how significantly they can affect energy markets.
Every Ontario Business Experiences This Differently
A 10-year demand record on the Ontario grid is one number. What it means for any specific business depends entirely on how that business uses energy.
A restaurant running full kitchen equipment, walk-in coolers, and dining room air conditioning through a sustained heat event is in a different position than a property management company keeping common areas comfortable across a portfolio of buildings. A farm managing ventilation, irrigation, and cold storage during record temperatures has a different energy profile than an automotive dealership keeping a showroom cool, or a manufacturing facility maintaining precise production floor conditions, or a grocery and retail operation running refrigeration around the clock.
This is not a theoretical distinction. The industries Ontario Wholesale Energy works with, including restaurants, manufacturing operations, farms and agricultural businesses, property management companies, automotive businesses, retail and grocery operations, wineries, warehousing and light industrial facilities, and multi-family residential buildings, each have their own load profiles, their own peak demand patterns, and their own exposure to events like today’s grid record.
Default utility contracts are not built around any of that. They are built for the grid.
Can Ontario Businesses Choose Their Own Electricity or Natural Gas Supplier?
Yes. Ontario operates an open energy market. Commercial businesses are not required to purchase electricity or natural gas at the default utility rate. The Ontario Energy Board licenses independent energy retailers who are authorized to offer commercial clients custom electricity and natural gas contracts as an alternative to the utility default.
The local utility still delivers the energy through its infrastructure. Your meter, your service address, your outage response, none of that changes. What changes is the contract structure behind your pricing, and who built it.
Most Ontario business owners are not aware this option exists. The default utility relationship requires no action to maintain, so most businesses stay on it without ever asking whether something built around how their specific operation runs might be available.
What Is a Boutique Energy Retailer and How Is It Different?
Ontario Wholesale Energy is a boutique licensed energy retailer.
A large utility builds rate structures for broad consumption patterns across millions of accounts. A volume-focused energy retailer may offer an alternative contract, but often one that is still relatively standardized.
A boutique energy retailer works differently. We look at how a specific business operates, what its electricity and natural gas load looks like, when its demand peaks, how its operations shift across seasons, and what conditions like a sustained summer heat event mean for that particular type of business. Then we build a custom electricity or natural gas contract around that reality.
Ontario Wholesale Energy is backed by Shell Energy North America and holds a full licence issued by the Ontario Energy Board. Both are verifiable credentials. We work across the full range of commercial industries listed above, and we have built our account base through direct, straightforward conversations.
What Is the Ontario Energy Board and Why Does It Matter?
The Ontario Energy Board is the provincial regulator for electricity and natural gas in Ontario. It licenses energy retailers, sets consumer protection rules, and oversees how energy is bought and sold in the province. Any legitimate energy retailer operating in Ontario holds a current OEB licence and operates under that regulatory framework.
Ontario has a difficult history with energy retailers. High-pressure sales tactics and poorly structured contracts left a mark on the industry’s reputation, and that reputation was earned. It is exactly why the OEB licence exists as the baseline credential any business should verify before entering into an energy contract with any retailer.
A Record Demand Day Is a Good Reason to Ask a Question You May Never Have Asked
Grid demand records and real-time price events are useful reminders that the energy market is not static. Default utility contracts treat it as if it were.
If your business has never had a conversation about whether a custom electricity or natural gas contract might be a better fit for how you actually operate, today is a reasonable day to start that conversation.

Frequently Asked Questions
What does a 10-year electricity demand record in Ontario mean for businesses?
It means the Ontario grid is under significant pressure. When demand reaches a 10-year peak, the grid draws on more expensive generation sources to keep up, and real-time electricity prices rise accordingly. For businesses on variable or default utility pricing, that pressure can show up on their energy bills. For businesses with contracts built around their specific load profile, the picture can be different.
What is the IESO?
The Independent Electricity System Operator is the body that manages Ontario’s electricity grid in real time. It balances supply and demand across the province, dispatches generation, publishes live pricing and demand data, and is the authoritative public source for what is happening on the Ontario grid at any given moment. Its data is publicly available at ieso.ca.
Do Ontario businesses have to use their local utility for electricity and natural gas?
No. Ontario’s open energy market allows commercial businesses to purchase electricity and natural gas through a licensed energy retailer instead of accepting the default utility rate. The utility still delivers the energy and maintains the infrastructure. The contract and pricing structure can come from a licensed retailer who builds it around how your business actually operates.
What industries does Ontario Wholesale Energy work with?
Ontario Wholesale Energy (ONIT Energy Ltd.) works with commercial clients across a wide range of industries including restaurants, manufacturing operations, farms and agricultural businesses, property management companies, automotive businesses and dealerships, retail and grocery operations, wineries, warehousing and light industrial facilities, boutique retail, and multi-family residential buildings. Each of these industries uses energy differently, which is exactly why a custom contract approach exists.
How do I know if an energy retailer in Ontario is legitimate?
Check for a current licence issued by the Ontario Energy Board. The OEB maintains a public registry of licensed energy retailers in Ontario. Any retailer that cannot point to a current OEB licence should not be given a contract.
Ontario Wholesale Energy (as ONIT Energy Ltd.) holds a current OEB licence and is backed by Shell Energy North America. Both are verifiable.
