Atlantic Canada Energy

The Atlantic Energy Landscape

Atlantic Canada encompasses four provinces—New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador—each contributing unique energy resources to the regional and national grid. The region is globally recognized for pioneering tidal energy development in the Bay of Fundy, which experiences the world's highest tides with vertical ranges exceeding 16 meters. These powerful tidal forces represent a vast untapped renewable resource that Atlantic Canada continues to explore through innovative turbine technologies and in-stream generation systems.

The region's energy portfolio extends far beyond tidal power. Newfoundland and Labrador's Churchill Falls facility has produced hydroelectric power since 1971, generating 5,428 megawatts—one of the largest underground power stations globally. The newer Muskrat Falls project, commissioned in 2019, adds 824 megawatts of hydroelectric capacity, representing a major infrastructure investment in clean energy generation. These hydroelectric installations provide baseload power while maintaining ecological considerations through advanced fish passage systems and environmental monitoring protocols.

Offshore wind development marks the next frontier for Atlantic energy. Nova Scotia's Deep Panuke and Sable projects demonstrate the region's capacity for offshore energy infrastructure, while emerging floating wind turbine technologies promise to unlock deeper water resources. The province has set ambitious targets for renewable energy, aiming for 80% renewable electricity by 2030. New Brunswick maintains a diversified energy mix including the Point Lepreau Nuclear Generating Station, which provides approximately 30% of the province's electricity, alongside expanding wind and solar capacity.

Key Energy Projects

Bay of Fundy Tidal Power

Location: Nova Scotia/New Brunswick

Capacity: Multiple demonstration projects (2-4 MW each)

Technology: In-stream tidal turbines

Significance: The Bay of Fundy's extreme tidal range creates ideal conditions for tidal energy generation. The Fundy Ocean Research Center for Energy (FORCE) operates the world's leading tidal energy test site, where various turbine designs are evaluated under real-world conditions. These demonstration projects have generated valuable data on turbine durability, environmental impacts, and grid integration strategies. The region's tidal resource could theoretically generate 2,500 megawatts of clean electricity.

Challenges: Harsh marine environment, turbine maintenance, environmental monitoring, grid connection costs, and balancing economic viability with ecological protection.

Muskrat Falls Hydroelectric

Location: Labrador, Newfoundland and Labrador

Capacity: 824 megawatts

Technology: Run-of-river hydroelectric

Significance: The Muskrat Falls facility on the Churchill River represents one of Atlantic Canada's largest energy infrastructure investments. Commissioned in 2019 after years of construction, the project includes not only the generating station but also the 1,100-kilometer transmission system delivering power to Newfoundland and potentially to Nova Scotia via undersea cables. The facility provides clean baseload electricity, reducing reliance on thermal generation and supporting provincial climate goals.

Environmental Measures: Advanced fish passage systems, methylmercury mitigation strategies, Indigenous consultation processes, and comprehensive environmental monitoring programs ensure responsible operation.

Offshore Wind Development

Location: Nova Scotia and Newfoundland coasts

Projected Capacity: 5,000+ megawatts by 2030

Technology: Fixed and floating offshore wind turbines

Significance: Atlantic Canada's offshore wind resource ranks among North America's strongest and most consistent. Nova Scotia has designated areas for offshore wind development, with auction processes attracting international developers. Floating wind turbine technology enables access to deeper water sites with stronger, more consistent winds. These projects could position Atlantic Canada as a green hydrogen producer, using offshore wind to generate hydrogen for export to European and domestic markets.

Economic Impact: Job creation in manufacturing, installation, and maintenance; supply chain development; port infrastructure investment; and potential for green hydrogen industry expansion.

Churchill Falls Hydroelectric

Location: Labrador, Newfoundland and Labrador

Capacity: 5,428 megawatts

Technology: Underground hydroelectric facility

Significance: Operational since 1971, Churchill Falls remains one of the largest underground power stations worldwide. The facility diverts water from the Churchill River through a complex system of dikes, dams, and tunnels to generate massive amounts of clean electricity. Long-term power purchase agreements supply electricity to Quebec, with contract renewal negotiations ongoing regarding benefit sharing. The facility demonstrates the longevity and reliability of large-scale hydroelectric infrastructure.

Engineering Achievement: Eleven turbine-generator units housed in underground powerhouse carved from bedrock, demonstrating remarkable civil engineering and ongoing operational excellence over five decades.

Energy Transition Initiatives

Atlantic provinces are actively pursuing aggressive renewable energy targets to reduce greenhouse gas emissions and transition away from coal-fired generation. Nova Scotia eliminated coal entirely from its electricity generation by 2030, replacing it with renewable sources and natural gas. The province's Marine Renewable Energy Act provides a regulatory framework for tidal, wave, and offshore wind development, streamlining approvals while ensuring environmental protection.

New Brunswick's energy strategy emphasizes grid modernization, energy efficiency programs, and small modular reactor (SMR) technology development. The province hosts research into next-generation nuclear reactors that could provide clean baseload power for remote communities and industrial applications. Prince Edward Island achieved over 95% wind energy penetration by 2025, demonstrating that small jurisdictions can rapidly transition to renewable electricity with appropriate grid management and interconnection capacity.

Marine Energy Research

The Fundy Ocean Research Center for Energy (FORCE) operates the world's premier tidal energy testing facility in the Minas Passage. The site features four underwater berths capable of testing turbines with up to 16 megawatts total capacity. Comprehensive environmental monitoring examines effects on fish, marine mammals, and benthic ecosystems. Data collected informs turbine design improvements, installation methods, and operational protocols. International collaboration brings together European, Canadian, and American developers to advance tidal energy technology.

The Ocean Tracking Network, headquartered at Dalhousie University, monitors marine species movements to assess potential interactions with tidal turbines. Acoustic tagging studies track fish behavior near turbine sites, while underwater video systems document species presence. This research ensures that tidal energy development proceeds responsibly with minimal ecological disruption. Similar monitoring extends to offshore wind development areas, creating a comprehensive understanding of marine energy's environmental footprint.
