Efficiency Canada Argues Doubling Grid Capacity Misses

Efficiency Canada published a policy commentary on May 15, 2026, arguing that the Powering Canada Strong electricity strategy (released the same day) understates the role of energy efficiency in meeting Canada’s 2050 electricity needs. The Carleton University-affiliated research group’s central claim is that doubling energy productivity, which the federal government has already committed to internationally under the Glasgow Energy Pact, would cut roughly in half the new generation capacity the strategy assumes is needed.

The Argument

Efficiency Canada notes that the Powering Canada Strong document focuses on supply-side investments (generation, transmission, storage, workforce) and assigns relatively limited emphasis to demand-side measures. The commentary cites Efficiency Canada’s earlier modeling work showing the levelized cost of saved electricity from efficiency programs at approximately $0.03 per kilowatt-hour, compared to $0.12 to $0.18 per kilowatt-hour for new utility-scale generation including transmission and integration costs. The implication is that every kilowatt-hour avoided through efficiency displaces 4 to 6 times its cost in supply-side investment.

Why It Matters

Provincial utility commissions reviewing integrated resource plans through 2026 and 2027 should weigh demand-side resource potential against the assumed supply-side buildout, particularly in jurisdictions where industrial efficiency programs have been underfunded relative to residential. The C$1 trillion supply-side commitment in Powering Canada Strong creates a budgetary anchor that demand-side advocates will struggle to compete with politically; investor-owned utilities benefit financially from rate-based supply-side investments in ways that demand-side programs typically do not. Procurement officers at large industrial and institutional consumers should reassess their own demand-side spending given the federal strategy’s implicit pricing signal that supply expansion will dominate.

Critical Perspective

Efficiency Canada’s critique is internally consistent and rests on widely accepted levelized-cost numbers, but the framing that efficiency could halve required new generation overstates the realizable potential in practice. Demand-side programs face well-documented free-rider problems (paying for upgrades that would have happened anyway), measurement-and-verification challenges, and political constraints on the rebate levels needed to motivate the efficiency choices most likely to deliver large savings. The Glasgow Pact commitment to doubling energy intensity improvement applies to the entire economy including transportation and industrial process heat, not just electricity, so directly mapping that commitment onto Canadian electricity demand overstates the policy’s reach. The Powering Canada Strong strategy could be revised to include a stronger demand-side component without invalidating its supply-side framework; framing the two as oppositional understates the reality that both will be needed if Canada is to electrify transportation and heating without runaway capital costs. The more productive critique would press the federal government on the specific demand-side budget line items absent from the strategy document, rather than dismissing the supply-side framework as fundamentally misaligned.
