How Ontario Businesses Can Reduce Electricity Costs
Thanks to a recent policy change, large businesses in Ontario can start to gain control of the GA charges that drive up their annual electricity costs.
Since 2010, Ontario businesses that qualified for the Industrial Conservation Initiative (ICI) were assessed an annual GA rate based on their contribution to peak demand on the grid. The GA charge for each building was calculated based on that building’s demand at the top five peak demand hours for the Ontario grid every year. This created the opportunity for these buildings to reduce their annual GA charges—if you can predict when peak demand is most likely to occur and temporarily reduce your demand for that period, you can reduce your GA charge.
In 2017, Ontario expanded eligibility for the ICI. Whereas the program was previously limited to buildings with an average peak demand of 5 MW or greater, the program is now open to all buildings with a peak demand of 1 MW or greater, as well as those in select industries with a peak demand of 500 kW or greater.
However, while expanding ICI eligibility opened this opportunity to far more Ontario businesses, it did not address the two main challenges to fully capitalizing on the opportunity to manage GA costs: accurately predicting when peak demand will occur on the grid, and reducing demand in a significant way without disrupting operations in your buildings.
This is where an intelligent energy storage solution can play an important role. When combined with insight into trends on the Ontario grid, businesses can seamlessly transition a portion of their building’s load onto an energy storage system at the times when system peak is most likely to occur throughout the year. This will reduce a building’s demand on the grid without requiring the shutdown of key equipment. Their buildings will experience no difference in energy consumption, but their GA charges will decrease as if they did. Businesses that reduce their peak demand factor by 1 MW stand to save more than $500K in GA charges in the following year.
Ontario businesses face one of the biggest opportunities for energy storage not just in Canada, but in all of North America. While incentive programs like the ICI—as well as regional demand response programs—open the window for these businesses to take control of one of their biggest operational cost drivers, energy storage is the key to maximizing the value of these opportunities.
