Energy Storage Canada outlines Canada’s potential to lead the energy storage sector, emphasising the need for stable trade policies and innovative industrial strategies to secure this future.
Canada is already emerging as a global leader in energy storage deployment. Whether the country converts that early leadership into lasting advantage will depend less on technology and more on innovative policy choices being made on trade, supply chains and industrial strategy.
In the past decade, Energy Storage Canada has seen energy storage technologies move from the margins of system planning to the core of electricity grid modernisation. Provinces no longer view storage as a pilot technology or niche resource, but as essential infrastructure supporting reliability, peak capacity and system flexibility. That shift is evident in procurement volumes, market reforms and long-term resource planning across multiple jurisdictions.
Canada has moved beyond demonstration-scale deployment. More than 430 megawatts of energy storage are operating in Ontario today. Alberta has approximately 200 megawatts, Nova Scotia energised 100 megawatts near the end of 2025 and a range of smaller scale projects at 20 megawatts or less are scatted across the country. Taken together, Canada has more than 700 megawatts of grid-connected energy storage already in service, with additional capacity contracted and a full gigawatt of storage resources operating well in sight.
The current status for Canada’s energy storage capacity
Ontario and Alberta are leading near-term deployment, reflecting rapid demand growth, evolving market structures, and changing system needs in both provinces. In Ontario, storage is being procured to support the electricity system through a period of transition that includes both asset retirement and refurbishment. Storage is playing a growing role in replacing retiring capacity, managing peak demand and supporting projected load growth as electrification accelerates. In Alberta, market reforms and the operational realities of an energy-only market have positioned storage as a critical resource for reliability, flexibility and capacity. Meanwhile, other regions, from British Columbia to Atlantic Canada, are increasingly turning to storage to strengthen grid resilience, reduce reliance on diesel generation, integrate variable clean power and support affordability.
This growth in the storage sector positions Canada as a modern and competitive energy provider for trade and export. The country continues to invest in and export oil and gas, and that reality underscores the importance of having electricity systems that are reliable, flexible and globally competitive with a diverse range of generation resources. Energy storage is becoming a key part of that foundation. It also creates a real opportunity to build Canadian domestic industrial capacity in one of the world’s fastest-growing energy sectors.
The importance of policy stability in energy storage
Realising this opportunity, however, depends on something less tangible than project announcements or capacity targets. It depends on innovative policy to ensure supply chain and trade confidence in Canada’s market.
Energy storage projects rely on a complex global supply chain. Batteries, inverters, power electronics, steel enclosures, thermal management systems, controls and balance-of-plant components must meet strict safety, performance and warranty standards. These requirements are fundamental to securing financing, insuring assets and gaining system operator approval.
While Canadian companies have demonstrated leadership and innovation across the sector, a domestic manufacturing base does not yet exist at the scale needed to support near-term, multi-gigawatt deployment. Developers and utilities, therefore, rely on established Tier 1 global suppliers to manage risk and meet bankability requirements. This reflects the practical realities of building complex infrastructure quickly and at scale, not a lack of interest in Canadian manufacturing.
The global nature of the energy storage supply chain makes policy stability as important as policy ambition. Storage projects are capital-intensive and developed over multi-year timelines. Procurement commitments are often made years before construction begins. Financing decisions depend on predictable assumptions about equipment availability, costs and regulatory frameworks. Sudden changes to trade policy or procurement rules can quickly reshape project economics and timelines.
Recent and proposed trade measures, including steel tariffs and expiring tariff remissions, have brought these risks into sharper focus. Many affected components cannot currently be sourced domestically at scale. In the near term, without a ready domestic supply chain, such changes are unlikely to redirect demand toward Canadian suppliers. Instead, they risk increasing costs, introducing delays and creating financing uncertainty for projects already under contract or in procurement.
These impacts extend beyond individual projects. In regulated markets, higher costs ultimately flow to ratepayers. In competitive markets, they weaken the business case for projects providing essential system services. Delays to storage deployment also create system-level risks as electricity demand grows and legacy assets retire. None of these outcomes strengthen Canada’s electricity system or its economic competitiveness.
Strategies for strengthening domestic supply chains
There is a broad consensus across the energy storage sector that Canada should strengthen domestic supply chains and diversify international suppliers. Energy storage offers real opportunities in systems integration, power electronics, enclosures, software, controls, operations and services. Over time, deeper manufacturing investment may also become viable as deployment volumes grow. The challenge for policymakers is sequencing.
Mandatory domestic content requirements introduced before sufficient capacity exists risk slowing or cancelling projects during a critical deployment window. They can erode investor confidence and delay infrastructure that system planners already consider essential for reliability and affordability. A more effective approach is to use voluntary domestic content incentives that encourage Canadian manufacturing while preserving flexibility for near-term deployment.
International experience offers a clear lesson. The United States’ Inflation Reduction Act shows how predictable, long-term incentives can accelerate clean energy manufacturing while maintaining deployment momentum. The key driver is confidence that demand will exist long enough to justify building factories, training workers and investing capital. Abrupt policy shifts or status quo policy frameworks that don’t take the broader supply chain and shifting global economy into account risk undermining that confidence, even when the intention behind the policies is to support domestic industry.
Future outlook
Canada is now entering a multi-gigawatt phase of energy storage deployment. Capacity targets alone will not determine success. The pace, cost and reliability of deployment will depend on whether trade policy, procurement design and industrial strategy can innovate to provide informed, transparent processes for growing industries that are aligned and stable.
Energy storage is not a future opportunity. It is a present necessity for a reliable, affordable and competitive electricity system. Aligning trade stability with pragmatic domestic content incentives and a credible long-term industrial strategy would allow Canada to deploy storage at the pace its electricity system requires, while building a resilient supply chain that supports domestic development. That same stability would also allow Canadian companies to operate confidently in global markets, where bankability depends on predictable policy and proven infrastructure.
The window to get this right is open. It will not stay open forever.
