Not a deal yet – upgrades at Highgate converter station part of the talks – impact on electricity rates unknown

Vermont could become a gateway for Canadian offshore wind power entering New England under an agreement signed Wednesday, October 28, by Gov. Phil Scott and Nova Scotia Premier Tim Houston.
The three-year agreement calls for Vermont and the Canadian province to investigate expanded electricity transmission connections, including a possible new or upgraded Highgate Converter facility in northern Vermont that could help deliver offshore wind-generated electricity to the New England power grid.
For Vermont residents and businesses, the potential benefits include access to additional electricity supplies, improved grid reliability and possibly lower long-term energy costs. However, the agreement does not establish electricity prices, guarantee savings or commit either government to construction.
“As a small state, we can’t generate affordable, clean and reliable energy alone, which is why regional partnerships are critical to reaching our goals,” said Governor Phil Scott. “This agreement lets us explore how to put those strengths together in a way that keeps costs down for ratepayers, strengthens reliability across New England, and builds on the long friendship between our jurisdictions. I want to thank Premier Houston and his team for their partnership.”
Nova Scotia has emerged as a leader in offshore wind development and regional transmission cooperation, while Vermont is recognized for long-term transmission planning and least-cost clean energy development. The MOU advances both jurisdictions’ shared goals of energy independence, affordability, job creation, and environmental protection.
“Nova Scotia has one of the best offshore wind resources in the world, and partnerships like this help us turn that advantage into economic opportunity,” said Premier Tim Houston. “This agreement with Vermont is another important step as we build connections with energy partners, advance Wind West, and position Nova Scotia to become a clean energy superpower. By working together, we can create good jobs, attract investment, strengthen energy security, and help meet growing energy needs with clean, reliable power.”
The Memorandum of Understanding on Transmission Collaboration and Regional Grid Integration identifies Vermont’s existing Highgate Converter as a potential route for electricity generated by Nova Scotia’s offshore wind industry. The Highgate facility connects the New England electricity grid with Canada’s grid, allowing electricity to move between the two systems.
Under the agreement, the two governments will investigate expanding the facility’s ability to move electricity in both directions, potentially including a new converter. Nova Scotia is pursuing development of offshore wind resources capable of producing substantial amounts of renewable electricity. Vermont, meanwhile, is seeking affordable, reliable electricity supplies while maintaining its commitment to cleaner energy.
The agreement describes the two jurisdictions as having complementary strengths: Nova Scotia’s wind resources and Vermont’s experience with transmission planning and its existing connection to Canada.
The arrangement could have several implications for Vermont.
First, it could give Vermont and other New England states access to another source of electricity, potentially helping meet growing demand and reducing dependence on existing generation sources.
Second, expanded transmission capacity could improve the ability of utilities to move electricity between Canada and New England when supplies are tight or demand is high.
Third, Vermont could become an important transmission link in a broader regional energy network, although the agreement does not specify where new infrastructure would be built, how much it would cost or who would pay for it.
The agreement also raises questions about the economics of offshore wind power and transmission development. Any eventual project would need to account for construction costs, regulatory approvals, electricity market conditions and the effects on consumers.
The document specifically identifies technical feasibility, regulatory requirements, costs, benefits, market impacts, industry interest and siting constraints as subjects for further study.
