Initial Reports Assess Grid Preparedness for AI Data Centre
Nova Scotia’s electricity grid can theoretically handle a massive AI data centre project with significant equipment and infrastructure upgrades, according to new studies released by the provincial grid operator. The findings provide early insight into what would be required to integrate EverWind Fuels’ proposed data centre in Point Tupper, N.S., into the provincial power system.
EverWind Fuels’ Data Centre Plan
EverWind Fuels has announced plans to build a large AI data centre that will connect to Nova Scotia’s provincial power grid. Because of the significant energy demands involved, the company must receive approval from Nova Scotia’s Independent Energy System Operator (IESO), the body responsible for managing and dispatching electricity across the province.
The IESO began evaluating the project months prior to its public unveiling. With interest and concerns mounting regarding environmental effects, regulatory oversight, and the impact on grid operations, the IESO published the results of two initial system impact studies this week—one for each phase of EverWind’s plans.
Upgrade Costs and Infrastructure Needs
Both reports from the IESO conclude that the project could be integrated into the grid without adverse effects, as long as certain upgrades and changes are made to the power infrastructure:
- Phase 1 requires two upgrades—no cost estimate was provided in the initial report.
- Phase 2 identifies several modifications, including new infrastructure, with a preliminary non-binding cost estimate of $73.9 million. This estimate does not include further upgrades that might be needed as grid models are refined and studied in more detail.
EverWind Fuels has stated it will pay for any necessary changes or upgrades to Nova Scotia’s electricity grid associated with the data centre project.
Approval Process Ongoing
IESO officials emphasize that the findings published so far do not represent a final approval for the data centre’s grid connection. A spokesperson noted that further technical analysis and real-world testing are still required, and the project will not proceed to interconnection until all issues are resolved. If any part of the required testing fails, approval is withheld until solutions are found.
François Bouffard, associate professor of electrical engineering at McGill University, cautioned that there are still "significant blind spots" in the current analysis, in part because proprietary details about the data centre’s internal operations are not disclosed by developers. Bouffard believes the process is typical of AI data centre projects, which often keep proprietary information secret, complicating external assessments.
AI Data Centres Pose New Challenges
The potential impact of AI data centres on power grids remains a "hot topic" among engineers, according to Bouffard. He and other experts, including the Institute of Electrical and Electronics Engineers (IEEE), note that existing models for predicting the behavior of large data centre loads are still rudimentary. The IEEE’s recent report highlights an industry-wide lack of standardized engineering practices to accurately capture and address the reliability impacts that data centres can have on electrical grids.
Provincial Perspective on Grid Capacity
At a recent government committee meeting, senior provincial officials echoed the studies’ findings, saying Nova Scotia’s grid currently provides around 2,400 megawatts at peak, and for most of the year operates far below that capacity. "So for the most part, the grid is capable of delivering this volume of energy," David Miller, executive director of energy planning, told MLAs.
However, the grid was nearly overloaded during a recent winter cold snap, and deputy energy minister Stephen MacDonald said any further large-scale data centre projects would likely require additional generation capacity. Eight other interconnection requests for large-load customers are already in the queue, including two additional commercial projects, but none have advanced as far as EverWind’s proposal.
The process for new facilities involves multiple studies by both the grid operator and Nova Scotia Power. According to the utility, only projects that move beyond preliminary assessments to detailed impact studies indicate serious development intent—so far, no other data centre proposals have reached that stage in Nova Scotia.
