Energy Storage

After years of stable supply, Ontario is entering a period of need with demand expected to increase by 2 per cent per year over the next twenty years due to electrification, decarbonization and economic growth. Energy storage is well positioned to help support this need, providing a reliable and flexible form of electricity supply that can underpin the energy transformation of the future.

Storage is unique among electricity types in that it can act as a form of both supply and demand, drawing energy from the grid during off-peak hours when demand is low and injecting that energy back into the grid when it is needed most. Storage is particularly useful in supporting the wide-scale integration of renewable resources, like wind and solar, because it can help smooth out changes in energy output caused by unpredictable weather.

Ontario already has one of the cleanest electricity systems in North America, getting most of our power from hydro and nuclear generation. Energy storage can help leverage these existing assets while helping to enable more renewables to ensure clean, reliable and affordable electricity for Ontario’s homes and businesses.

Ontario’s electricity system moves forward with largest energy storage procurement ever in Canada.

Powering Grid Transformation with Storage

Energy storage is changing the way electricity grids operate. Under traditional electricity systems, energy must be used as it is made, requiring generators to manage their output in real-time to match demand. Energy storage is changing that dynamic, allowing electricity to be saved until it is needed most.
