Introduction — Learning from History to Power the Future
The idea of a national electricity grid
may sound like a modern energy debate, but its roots stretch back nearly a
century. In the late 1920s, Britain faced a patchwork of small, isolated power
stations using incompatible standards. This led to inefficiency, wasted coal,
and high costs. The solution? A unified
power network that revolutionized electricity distribution,
strengthened national security, and laid the groundwork for decades of economic
growth.
Fast forward to the 21st century, and Canada finds itself at a similar crossroads. We have abundant energy resources, but our electricity system remains largely provincial, with limited interconnection. In a time of climate change, increasing electricity demand, and growing geopolitical risks, the case for a truly national electricity grid has never been stronger.
Britain’s Example — How a Grid Transformed a
Nation
From Chaos to Coordination
In the 1920s, electricity in Britain was
produced and consumed locally. Hundreds of suppliers operated independently,
each using their own standards. This caused:
·
Duplicated infrastructure
·
Oversized reserves
·
Poor thermal efficiency
·
High generation costs
·
Massive coal waste
The Central
Electricity Board stepped in between 1928 and 1933, building
thousands of miles of transmission lines to link more than 120 power stations
into a single network.
Economic and Security Benefits
The transformation was dramatic:
·
Lower
Costs: Unified generation cut redundancy and improved
efficiency.
·
National
Security: During World War II, the grid allowed rerouting of
electricity from less affected areas to bombed regions, keeping arms factories
and critical services running.
·
Economic
Growth: Electrification spread faster and more evenly.
Had Britain lacked this interconnected grid during wartime, history might have turned out very differently.
Modern Warning Signs — Alberta’s 2024
Emergency Alert
In January 2024, Alberta faced a severe cold
snap that pushed the province’s electricity system to the brink. The system
operator issued an emergency
alert, urging residents to reduce usage to avoid blackouts. The
crisis was narrowly averted thanks to:
·
Public
cooperation in reducing demand
·
Imports
of electricity from British Columbia and Saskatchewan
This incident revealed just how fragile regional grids can be during extreme weather. It’s a warning that Canada must take seriously.
Why Canada Needs a National Electricity Grid
1. Preventing Blackouts
A national grid would allow electricity to
flow seamlessly between provinces. When one region experiences a shortage,
others can step in to supply power—avoiding crises like Alberta’s.
2. Lowering Costs for Consumers
Currently, provinces must maintain expensive excess capacity to meet
peak demand. With an interconnected system, capacity can be shared, reducing
the need for costly backup systems.
3. Supporting the Clean Energy Transition
Canada’s renewable energy potential is enormous
,but unevenly distributed:
·
Wind-rich
provinces like Alberta and Saskatchewan
·
Hydro-heavy
regions like Quebec, Manitoba, and BC
·
Solar
growth in Ontario and the Prairies
A national grid could balance supply and
demand by:
·
Storing surplus wind or solar energy in pumped hydro facilities
·
Using high-voltage
direct current (HVDC) lines to transmit power long distances
with minimal losses
· Returning stored energy when renewable output drops
The Economics of Interconnection
Cost vs. Benefit
Building a national grid is expensive.
High-voltage transmission lines, interconnectors, and storage facilities
require billions in investment. But the avoided
costs are significant:
·
Reduced
outage risks
·
Lower
peak demand pricing
·
Less
need for emergency backup
For example, the 2023 Ontario–Québec electricity trade
agreement proved that shared infrastructure can lower costs and
improve reliability.
East-West vs. North-South Trade
Currently, many power trade routes are north-south connecting Canada to the U.S. While profitable, this leaves us vulnerable to international market fluctuations. An east-west corridor would:
·
Strengthen domestic supply security
·
Protect against trade disruptions
· Enable nationwide distribution of low-cost energy
National Security Considerations
Power as Critical Infrastructure
Electricity is no longer just about
economics it’s a pillar of national
security. Military manufacturing, data analysis, and other
defence-related activities depend on reliable energy. A national grid would:
·
Help Canada meet NATO’s civil preparedness target
of 1.5% of GDP
· Ensure energy resilience in times of geopolitical tension or cyber threats
Projects in Motion — and Setbacks
In Progress
·
ATCO and TC Energy exploring east-west grid

·
Hydro-Québec and Manitoba Power showing interest
·
Ontario easing trade barriers for energy deals
·
Manitoba and BC planning new energy corridors
·
Ottawa’s One
Canadian Economy Act backing major infrastructure projects
Challenges
·
Fragmented
regulation between provinces
·
Abandoned
projects like the Atlantic Loop
· Lack of national vision and political consensus
Lessons from Wartime Britain for Canada
Britain didn’t fully realize the strategic value of its grid until it was tested under fire. Canada could face similar situations whether from climate disasters, cyberattacks, or geopolitical crises. Building a national electricity grid now is a proactive step that could one day be the difference between resilience and collapse.
How to Make It Happen
To turn the national grid from idea to reality,
Canada needs:
1.
Federal-Provincial
Collaboration
Align energy regulations and create shared funding models.
2.
Public
Support
Highlight both economic and security benefits to build public momentum.
3.
Strategic
Investments
Prioritize HVDC lines, renewable integration, and large-scale storage projects.
4.
Phased
Implementation
Start with high-demand corridors, then expand nationwide.
Conclusion — A Vision for Canada’s Energy
Future
The call for a national electricity grid
is not just about cutting costs or boosting efficiency. It’s about future-proofing the nation.
Just as Britain’s grid became a lifeline in wartime, Canada’s could safeguard
us in the face of climate change, global instability, and growing electricity
demand.
Our leaders must act now. The investment is large, but so are the stakes. A connected Canada is a stronger, more resilient Canada.
