The Basics of Global Adjustment
Global Adjustment is a monthly charge on Ontario electricity bills, and these costs have been increasing since 2010. For Class A customers—those with peak demand over 5 MW, and others in certain industries with peak demand above 1 MW or 500kW—GA charges are set based on a company’s electricity use during the grid’s five system-peaking hours between May and April of the previous year.
What’s Changed with Global Adjustment
GA has been growing for the past decade, and is often the largest line item on electricity bills. As a result, the new budget seeks to shift some of the burden from the Global Adjustment cost to the general tax base, leading to lower Global Adjustment costs for commercial and industrial customers.
Global Adjustment will remain a significant cost, but Class A demand charges are expected to decrease by approximately 20-30%. This will result in overall energy bill savings of ~15% for most customers.
Takeaways for Commercial and Industrial Companies
These changes are expected to provide net energy savings to companies amid the challenges created by COVID-19.
Many Ontario companies use assets like storage systems to manage their peak demand and minimize their GA charges. While GA charges are decreasing, this does not affect the importance of these assets—GA will still very likely remain the most expensive line item on any utility bill in North America, and the methodology behind the calculations hasn’t changed. These systems remain the best way to minimize such costs.
Other Recent Changes in Ontario
This most recent change to GA comes on the heels of several other noteworthy changes in Ontario this year, many in response to the COVID-19 pandemic. The IESO and Government of Ontario have also:
- April 2020: Deferred global adjustment costs during the peak of the pandemic shutdown and reallocated those costs to next year’s global adjustment
- July 2020: Adopted a one-year hiatus for the Industrial Conservation Initiative (ICI) peak mitigation program
- September 2020: Extended the life of the Pickering Nuclear Generating Station as a capacity market resource. As a result, there will be no winter demand response enrollments during the 2021/2022 delivery year, since the IESO is forecasting a surplus of capacity due to nuclear power generation
The net impact for most customers from these changes should be a reduction in net energy expenditures.
