Reduce Global Adjustment charges

With the world leader in energy storage

Electricity Pricing Trends

Despite decreasing kWh costs, total cost of energy is rising as Global Adjustment charges increase rapidly.

Unleashing the benefits of energy storage technology is a key focus of Ontario’s 2017 Long-Term Energy Plan and an important part of our continued commitment to improve energy affordability for our province’s job creators.

How do Global Adjustment charges impact businesses?

All energy users in Ontario pay the Global Adjustment (GA) fee in some form, while commercial and industrial customers with load over 500 kW may pay GA based on their contribution to the grid’s five highest peaks.

For most customers, GA charges make up more than half the monthly electricity bill. In some months, GA comprises up to 90 percent of LDC bills.

GA costs are driven by the timing of energy use. If you rely on the grid at the same time as other companies, you’ll bear the costs. If you avoid using the grid at peak times, you’ll gain significant savings.

Today, a single megawatt-hour of energy consumption during Ontario’s five high peaks costs over $500,000. And recent trends and industry research suggest that GA could continue rising at a considerable rate.

Fortunately, there are AI-powered energy storage solutions available today which automatically switch your facility to stored battery power during Ontario’s highest peak periods.


How AI-powered energy storage
automatically lowers GA fees

You can attempt to reduce usage during peak times, but this process is manual, disruptive, inefficient, and often ineffective. It requires constant tracking and guesswork.

Energy storage powered by artificial intelligence (AI) automates this process for you. During those peak hours, Stem’s AI, Athena, discharges stored power so that your building seamlessly draws power from Stem’s batteries instead of from the grid, dramatically lowering GA fees.

With Stem’s service agreement, there is no upfront cost and no hassle. Stem manages everything–design, installation, maintenance, 24/7 real-time system monitoring, and automated operation. No resources are required from your facility. The system is completely automated and operates in the background, requiring no change or disruption to operations, allowing your staff to focus on their core objectives.

Stem’s AI-driven platform and execution experience enables an automated way to reduce energy costs with no interference in our operations.

highly recommend Stem

Stem operates more commercial-scale storage systems than all other providers combined.

Stem is proud to work with distinguished manufacturing and industrial companies, including:

Athena: The brains
behind the battery

A battery is only as valuable as the platform that operates it. Stem is the first to use artificial intelligence to learn, predict and optimize energy in real-time. Athena™ collects data at a rate of 400 megabytes per minute to continually fine-tune its algorithms. Athena has learned from operating systems for over 5 million hours, from processing nearly 200 million data intervals, and from running over 35 million project simulations.

Stem’s software is best-in-class. It tells the battery when to store and discharge power, responds to demand response opportunities, and reduced our exposure to changing utility rates.

storage hardware

Stem uses UL-certified energy storage systems from the highest quality Tier 1 suppliers such as Tesla, Panasonic, and LG Chem. They have been thoroughly vetted and tested for safety and performance by independent third parties. Stem’s systems are available in multiple sizing configurations, indoor or outdoor, to match customers’ individual energy needs and building footprint.

I like that the system just works and we don’t have to do anything.
