Dear Editor,
I am writing in response to a recent letter comparing pumped storage and battery storage, which focuses mainly on cost. While project cost matters, there are other factors that must be considered.
As Canada responds to significant economic challenges, governments are prioritizing made-in-Canada energy infrastructure that can strengthen the economy, create jobs, and support national resilience. Cost is one factor in evaluating these projects, but decision-makers must also consider their broader economic, strategic and long-term benefits.
If developed, Ontario Pumped Storage would create local jobs, support Canadian workers and suppliers, and generate significant economic activity across Ontario. While battery storage will play an important role in the province’s energy future, batteries and pumped storage serve different needs and differ significantly in lifespan, scale, supply chains, and long-term durability. Most battery systems are manufactured overseas and typically require replacement after 10 to 15 years, whereas a pumped storage facility can operate for many decades. Beyond energy storage, the project has the potential to support thousands of jobs, strengthen Ontario supply chains, generate substantial tax revenues, and provide a long-term infrastructure asset that contributes to the province’s economic and energy resilience.
Ultimately, it will be up to government decision-makers to determine whether the project delivers sufficient value for Ontario. Before the project could proceed, it must demonstrate that it is cost-effective, in the public interest, protective of the environment and capable of delivering value that justifies the investment.
At a time when governments are focused on energy security and reducing reliance on foreign supply chains, these benefits matter. The question is not simply which one technology appears least expensive on paper today. It is which investments deliver the greatest long-term value for Ontario’s electricity system, economy and energy independence.
Sincerely,
Clark Little
