The proposal to construct a 300-MW natural gas power generation facility in Salt Springs raises serious concerns about long-term energy security, climate alignment, and strategic planning for Nova Scotia’s electricity system.
1. Global experience shows the risks of continued reliance on fossil fuels
Across much of the world, jurisdictions are actively moving away from fossil-fuel-based electricity generation—not out of idealism, but out of necessity. Europe provides a stark and instructive example. The war in Ukraine exposed how deeply vulnerable gas-dependent power systems are to geopolitical shocks, supply disruptions, and price volatility.
In the United Kingdom, electricity prices are set through a marginal pricing mechanism, where the most expensive generator—often natural gas—determines the price for all electricity on the grid. As gas prices spiked, households and industries faced unprecedented energy bills, despite growing shares of renewable generation. This has had lasting social and economic consequences and has triggered renewed debate about the wisdom of gas-centric power systems.
This is not a hypothetical risk—it is a lived reality for millions of people. Nova Scotia should be learning from this experience, not repeating it.
2. A 30-year fossil fuel asset conflicts with climate commitments
The proposed facility is expected to operate for a minimum of 30 years. This timeline alone should raise red flags. Nova Scotia, like Canada more broadly, has made clear commitments to deep greenhouse gas reductions and net-zero targets within that same timeframe.
There is no such thing as a “clean” fossil fuel when used for combustion-based electricity generation. While natural gas may emit less carbon dioxide than coal, it remains a significant source of GHG emissions and methane leakage across its supply chain. Locking in new gas infrastructure today creates a structural dependency that makes future emissions reductions harder, more expensive, and more politically difficult.
Once built, these facilities do not simply disappear when cleaner options become available—they demand utilization to justify their capital cost, risking long-term carbon lock-in.
3. Why is demand-side management and efficiency not the priority?
Perhaps the most concerning aspect of this proposal is not what it includes, but what it sidelines. Demand-side management (DSM) and energy efficiency remain the lowest-cost, lowest-risk, and fastest-to-deploy resources in any electricity system.
Nova Scotia continues to waste enormous amounts of energy in:
-
Poorly performing buildings
-
Inefficient industrial processes
-
Under-optimized commercial energy use
Every megawatt avoided through efficiency is a megawatt that does not need to be generated, transmitted, or backed up with fossil fuel capacity. Jurisdictions that have aggressively pursued DSM have consistently shown that reliability can be maintained—often improved—without expanding fossil infrastructure.
The question that must be asked is: why are we planning new gas capacity before fully exhausting our efficiency and demand-reduction potential?
4. The need for genuinely long-term thinking
Energy infrastructure decisions made today shape outcomes for generations. A 30-year gas plant reflects short-term system thinking in a world that demands long-term resilience.
True long-term planning would prioritize:
-
Deep energy efficiency and DSM
-
Grid-scale storage and flexible demand
-
Electrification aligned with renewable generation
-
System resilience that does not depend on volatile fuel markets
Nova Scotia has the opportunity to design an electricity system that is resilient, affordable, and aligned with its climate goals. Committing to new fossil fuel infrastructure at this moment risks undermining all three.
We should be thinking not just about the next reliability challenge—but about the energy system we want to leave behind.
