The province's abundant offshore wind resources and strategic locations position it as a potential key contributor to regional renewable energy expansion. The proposed subsea cable routes provide a viable means to strengthen Nova Scotia's energy security by facilitating electricity export and import with Quebec and New England.This thesis examines Nova Scotia’s potential as a clean electricity source by integrating offshore wind with subsea cable interconnections. The province targets 80% renewable electricity and plans to lease 5 GW of offshore wind by 2030 to support green hydrogen production. The study uses this target to assess offshore wind generation and potential electricity exports to Quebec and New England. Simulations of 5 GW offshore wind farms at Sable Island, Sydney, and Yarmouth show an annual generation potential of 14–17 TWh, exceeding Nova Scotia’s projected 12 TWh demand by 2035, indicating a surplus. Future demand in Hydro Québec and New England, driven by electrification, is estimated at 25 TWh by 2032 and 21 TWh by 2033. The Proposed subsea cable routes include Point Aconi to Havre Saint-Pierre, Yarmouth to Boston, and Sable Island to both destinations. These interconnections could optimize offshore wind utilization and mitigate curtailment issues.enSubsea cableOffshore windHVDC transmissionCurtailmentClean electrcity
