EverWind Fuels signed a connection contract and a letter agreement with Nova Scotia Power binding the developer to cover at least $74 million in system upgrade costs for an $8-billion data centre campus in Point Tupper.
The Bottom Line
- EverWind accepted an interruptible load agreement requiring the facility to shut down within 10 minutes when the grid experiences strain.
- An additional letter agreement assigns all incremental system upgrade costs, estimated initially at $74 million or more, directly to the data centre developer.
- The Nova Scotia Energy Board retains final authority over approving the permanent tariff and determining exact cost allocations for the project.
Connecting to the Provincial Grid
EverWind signed two documents with Nova Scotia Power laying out conditions to link the first phase of its planned Point Tupper data centre to the provincial grid, CBC reported.
The connection contract specifies an interruptible load arrangement, meaning the utility or grid operator can direct EverWind to halt power demand with 10 minutes of notice. Nova Scotia Power said that service contracts are standard for new non-residential customers connecting to the system.
“Because we haven’t had a customer of this size connect in many years, the additional letter agreement was developed to provide more context to the [contract],” Jacqueline Foster, spokesperson for Nova Scotia Power, said via email to CBC.
EverWind has proposed installing on-site backup batteries and a diesel generator to maintain operations during curtailment periods. The interruptible structure mirrors agreements held by other large industrial customers designed to protect residential ratepayers during periods of high grid stress. Many Nova Scotians have been skeptical of the proposed campus amid concerns over grid reliability and high household electricity rates.
Allocating Infrastructure Upgrade Costs
The supplementary letter agreement ties all new system costs related to the data centre to EverWind, with early estimates placing necessary grid upgrades at $74 million or higher. Brendan Chard, EverWind’s vice-president of power, told CBC that memorializing these protections was critical to ensuring public confidence.
“For us, it was really critical that our commitment to protecting other ratepayers and the method in which that would happen was memorialized,” Brendan Chard, vice-president of power for EverWind, told CBC in an interview.
The letter agreement explicitly notes that EverWind accepts responsibility for interim incremental costs reasonably attributable to the new load. Those tracking, determination, and payment methods remain subject to formal review and approval by the Nova Scotia Energy Board. Scott Balfour, head of Emera — Nova Scotia Power’s parent company — stated during a quarterly earnings call that large load customers can support broader system investments if structured properly.
| Project Detail | Reported Metric |
|---|---|
| Total Campus Investment | $8 Billion |
| Initial System Upgrades Estimate | $74 Million+ |
| Grid Notice Window for Curtailment | 10 Minutes |
Stakeholders Develop New Tariff Applications for Large Industrial Customers
EverWind agreed to utilize an existing interim tariff designed for large industrial customers until regulators finalize a permanent rate class. Foster explained that because the existing tariff was not built for a customer of EverWind’s scale, stakeholders including the Independent Energy System Operator-NS must develop a new application.
“We will work with data centre proponents, the Independent Energy System Operator-NS and regulatory stakeholders on a proposed tariff application,” Jacqueline Foster, spokesperson for Nova Scotia Power, told CBC, noting the timeline is still to be determined.
Chard acknowledged that while predicting the final tariff structure remains difficult, the core commitment to insulating other ratepayers from cost increases stays fixed.
“What will not change is our commitment to not putting any costs on other ratepayers,” Brendan Chard, vice-president of power for EverWind, told CBC.
