Ontario’s Global Adjustment event hits in the late afternoon. The battery discharges to capture the peak, and reduce demand during the most consequential hours.

The scene

It is a hot afternoon in August, and your plant is doing exactly what it should

The line is moving. Compressors, presses, and chillers are pulling hard. Orders are going out the door on time. From the floor, it is a good day.

What no one on the floor can see is that the whole province is putting stress on the grid at the same moment. Air conditioners across Ontario switch on together, demand surges, and the grid leans on its most expensive generation to keep up. For a Class A facility, this single hour is about to become one of the most costly of the entire year, long after the heat wave is forgotten.

For more than a decade, Peak Power has forecasted these GA events and used battery storage for manufacturing in Ontario to turn moments like this from a cost of business into a line item large manufacturers control.

Energy is a structural cost for the average manufacturing facility — part of cost of goods sold.

In Ontario, Global Adjustment is now roughly a third of a large facility’s total electricity cost.

Those Global Adjustment charges are set by your demand during just five hours across an entire year.

The challenge

Global Adjustment: The Biggest Energy Cost for Ontario Manufacturers

For a Class A facility, Global Adjustment is now roughly a third of the electricity bill — and under Ontario’s Industrial Conservation Initiative (ICI), how much of it you pay is set by your share of provincial demand during the five highest-demand hours of the year, the coincident peaks. Your demand in those five hours becomes your Peak Demand Factor — the slice of the province’s Global Adjustment costs you carry for the next twelve months. The problem is simple to state and brutal to solve: the province does not tell you the five hours in advance, or even in real-time, and you cannot run a plant by guessing.

Infrastructure costs contributing to GA

Ontario's Darlington and Pickering refurbishments are set to add roughly $39.6 billion to the Global Adjustment cost base.

GA Costs projected to rise past 2030

Global Adjustment costs could reach $900,000 per megawatt by 2044 as supply contracts expire, demand rises, and new nuclear costs land on the bill.

Shifts you cannot simply switch off

You have production quotas, union crews, and delivery deadlines. Curtailing load by shutting down equipment is not an option when there's production to get off the line.

So how do you cut demand during a specific window of five hours, in a plant you can’t turn off?

Overcoming the obstacles

How Battery Storage Reduces Global Adjustment for Manufacturers

Peak Power closes the gap between “we should reduce demand” and “we did” with three things working together: industry-leading grid event forecasts, a battery that acts on them automatically, and a no-CAPEX battery financing model that removes the capital barrier entirely.

GridPredict forecasting

Our peak-prediction engine forecasts Ontario’s coincident peaks with greater than 90% accuracy, to know which hours matter before they happen. No peak-chasing, no spreadsheets, no guessing.

>90% peak accuracy

Automated battery dispatch

When a peak is coming, the on-site battery discharges to carry your facility through it. AI-enabled operation shaves the peak automatically, so production never feels it and your demand from the grid is curtailed.

Zero line disruption

No upfront cost

Through our shared-savings model, Peak Power or our investment partners fund the system. You pay nothing in capital, we earn a share of the savings we create, and our incentives stay aligned with yours.

Which Ontario Manufacturers See the Best Battery Storage ROI

Industrial peak shaving rewards facilities whose demand spikes well above their average — the bigger the gap between peak and baseline, the more there is to shave. Most Class A manufacturers running 1 MW or more qualify. These are the verticals where the returns are strongest.

Food & dairy processing, cold storage

Refrigeration and compressors run around the clock, so your demand almost never lets up. When a Global Adjustment event is coming, the battery discharges to carry that load, so your metered demand drops during these critical hours without affecting your operations.

Plastics, injection moulding, extrusion

Moulding and extrusion pull power in sharp, cyclical bursts that push your peaks high. During forecast GA peak events the battery discharges and holds your grid draw down when it counts, without slowing a single cycle.

Metal fabrication, stamping, automotive parts

Presses and furnaces sit on a large, steady base load and then expereince large spikes. The battery shaves those spikes during the GA windows and reduces your metered demand even on a plant that rarely idles. At this scale, every kilowatt off the peak is serious money.

Heavy HVAC loads

Cooling load climbs on hot afternoons, the same hours that tend to trigger Global Adjustment events. The battery discharges through those peaks so your equipment continues running, cutting your electricity demand at the priciest hours of the year.

The transformation

From an energy bill you brace for, to one you direct

When five hours a year no longer dictate your costs, energy shifts from a volatile threat to a managed opportunity. And the savings can fund the things that matter most to your facility.

Common questions

Battery Storage for Manufacturing in Ontario: FAQ

Answers to what Ontario energy and facility managers ask most about reducing Global Adjustment with battery storage.

How does battery storage reduce Global Adjustment costs?

In Ontario, a Class A facility’s Global Adjustment is set based on its share of provincial demand during the five highest-demand hours of the year. Battery storage charges off-peak and discharges during those forecasted coincident peaks, lowering your metered demand at the exact hours that count — which cuts your Peak Demand Factor and your Global Adjustment bill for the following year.

Does my facility qualify as a Class A customer under the ICI?

Most mid-to-large manufacturers do. Any facility averaging over 1 MW of monthly peak demand can opt in; manufacturers specifically (NAICS 31–33) can opt in from 500 kW, and sites above 5 MW are enrolled automatically. However, enrolling as Class A pays off most when you can reduce load during Global Adjustment events.

How much can an Ontario manufacturer save with battery storage?

It depends on your load profile and Global Adjustment exposure, but Peak Power has delivered about $160,000 per megawatt in average annual value for Ontario customers, and demand-charge reductions of 25–50% are common on peaky loads. Facilities with sharp, intermittent demand peaks see the strongest returns.

What is peak shaving, and will it disrupt production?

Peak shaving means trimming your electricity demand during the costliest hours. With Peak Power, the battery does it automatically. It discharges energy from the battery to reduce your draw from the grid during a forecasted peak event, without any blip to your system. There is no need to shut down equipment or send crews home.

What does battery storage cost to install?

Through Peak Power’s no-CAPEX shared-savings model, a client is not required to invest any capital in the project. Peak Power and its investment partners fund, build, and operate the system, and earn a share of the savings created. Your incentives and ours remain aligned throughout the battery’s entire lifecycle.

Will Global Adjustment costs in Ontario continue to rise?

Yes. Global Adjustment is trending structurally higher. The renewable cost-shift relief that currently trims about 14% off Class A bills is projected to unwind gradually through the 2030s as Ontario’s legacy renewable contracts expire, while newer availability-based generation contracts, expiring power-purchase agreements, and Darlington’s nuclear refurbishment all flow onto the bill. Our breakdown of what’s driving Ontario’s Global Adjustment rates walks through each driver. Rising GA raises both the exposure and the savings opportunity for Class A manufacturers.
