Anthropic Signs 20-Year Deal for $10B Nova Scotia AI Data Center
EverWind's wind-powered campus in Point Tupper marks developer's first Canadian expansion
AI lab Anthropic has signed a 20-year lease with EverWind Fuels to anchor a $10 billion clean energy and data center campus in Point Tupper, Nova Scotia. The agreement marks Anthropic's first known compute capacity expansion into Canada as hyperscalers and frontier AI developers seek dedicated renewable energy infrastructure.
Key details
Pre-construction work has officially commenced on the site near Port Hawkesbury in Cape Breton, Nova Scotia. The campus represents $10 billion in private investment, comprising $8 billion allocated directly to data center development and operation, alongside $2 billion dedicated to expanding EverWind's regional onshore wind portfolio.
The facility's initial phase will deliver 95 MW of compute capacity by late 2027, followed by a planned expansion of an additional 325 MW in 2028, bringing total site capacity to 420 MW. To manage power supply intermittency and grid integration, the development includes several hundred megawatt-hours (MWh) of battery energy storage systems.
Power for the campus will be supplied through EverWind's Point Tupper Green Fuels project and regional wind developments. Phase 1 projects, including the Bear Lake, Windy Ridge, Kmtnuk, and Upper Afton wind farms, will connect to the provincial grid, while Phase 2 Guysborough wind projects will deliver direct power via a dedicated overhead transmission line crossing the Strait of Canso.
Why this matters
As grid interconnection queues and power availability tighten across primary U.S. markets like Northern Virginia and Texas, frontier AI developers are increasingly turning to international sites with co-located renewable generation. Anthropic's $10 billion commitment demonstrates the growing necessity for AI companies to directly underwrite utility-scale wind generation and energy storage to secure long-term compute capacity.
Context
The Point Tupper site has hosted industrial infrastructure for over 50 years, previously serving as a traditional oil terminal. The transformation into a green hydrogen and AI compute hub reflects broader global trends where legacy fossil fuel sites are redeveloped into high-density compute infrastructure. Nova Scotia Premier Tim Houston highlighted that the project includes explicit commitments to protect local ratepayers from infrastructure grid upgrade costs while safeguarding regional water and energy resources.
Risks and open questions
Key questions remain regarding the timeline for completing the required transmission infrastructure across the Strait of Canso and integrating 420 MW of variable wind generation into Nova Scotia's power grid. Additionally, while the project incorporates battery storage, long-term grid backstop requirements during extended periods of low wind generation will be closely monitored by provincial energy regulators.
What happens next
Pre-construction environmental reviews and site preparation will continue in Cape Breton throughout 2026 and 2027. Developers will proceed with Phase 1 wind farm interconnections ahead of the target 95 MW operational date in late 2027, while regional utilities prepare transmission assets for the subsequent 325 MW expansion in 2028.
