Introduction
Wind West is Nova Scotia’s proposed large-scale offshore wind and transmission strategy (https://novascotia.ca/wind-west/), potentially involving around 5 GW in its first phase and requiring substantial associated investment in grid connection and export transmission. It is best understood not as a conventional single-market procurement programme, but as the first stage of a wider initiative to monetise Nova Scotia’s offshore wind resource through cross-border clean electricity exports.
Over the past year, Canada and Nova Scotia have moved the programme from policy concept into early implementation. The governments have designated the first four offshore Wind Energy Areas, launched a prequalification process, introduced a revenue framework and initiated route‑to‑market engagement with key export markets.
That progress is material, but the regime remains at an early stage of commercial design. The central question remains whether Nova Scotia can translate the emerging policy architecture into a coherent, financeable framework for transmission, offtake and long‑term revenue
stability.
What is Wind West?
Wind West is an export-led offshore wind strategy designed to enable Nova Scotia to become a major supplier of clean electricity to neighbouring markets, rather than relying primarily on the province’s domestic power market. That export focus is important: the scale of the offshore resource and the stated 40–60 GW long-term ambition substantially exceed what would ordinarily be absorbed by the provincial system alone.
The programme is positioned as a long-term 40–60 GW concept, with an initial phase aiming to license around 5 GW of offshore wind generation by 2030. The first phase is therefore intended to test not only project-level appetite, but also whether Nova Scotia can establish the commercial infrastructure needed for repeatable, large-scale offshore wind deployment.
The Government of Nova Scotia presents Wind West as part of a broader offshore wind and clean energy export proposition (https://novascotia.ca/offshore-wind/), with transmission development integral to unlocking export routes. In practical terms, generation, transmission and offtake will need to be developed as a single bankable chain with weakness in any one element likely to affect bidder appetite and financing terms for the others.
Nova Scotia’s wind resource is strong. Aegir’s value mapping describes Nova Scotia as having world-class offshore wind resources, with mean wind speeds broadly in the 9–11 m/s range, sizeable shallow-water areas and a combination of fixed-bottom and floating opportunities depending on location. However, Aegir’s analysis underlines that water depth, seabed conditions, proximity to ports and grid, fisheries, protected areas, shipping, seabirds, marine mammals and sea ice will all affect the practical development case.
Policy developments to date
Nova Scotia’s offshore wind policy has been supported by a phased sector roadmap (https://novascotia.ca/offshore-wind/docs/offshore-wind-roadmap-module-3.pdf), which frames legislative and regulatory development, supply chain planning and stakeholder engagement as parallel workstreams. The policy also sits within the jointly managed Canada–Nova Scotia offshore regime: the Canada–Nova Scotia Accord Acts were updated in 2025 to include offshore renewable energy and the Canada–Nova Scotia Offshore Energy Regulator is responsible for regulating offshore energy development under that framework.
On 29 July 2025, Canada and Nova Scotia jointly designated the first four Wind Energy Areas in the Canada–Nova Scotia offshore area (https://cnsoer.ca/renewable-energy/lands-management/governments-designated-offshore-wind-energy-areas):
- French Bank;
- Middle Bank;
- Sable Island Bank; and
- Sydney Bight.
The designation followed consultation on five proposed Tier 1 areas but Western/Emerald Bank was not included in the first designation and is expected to be considered after 2030, together with the Tier 2 areas identified through the regional assessment process.
In September 2025, Canada and Nova Scotia issued a strategic direction to the Canada–Nova Scotia Offshore Energy Regulator (CNSOER) (https://www.canada.ca/en/natural-resources-canada/news/2025/09/government-of-canada-and-nova-scotia-set-direction-for-offshore-wind-future.html), instructing it to implement a prequalification process and a Call for Information to inform the design of the first Call for Bids. The strategic direction will help move the programme from area identification towards the competitive allocation of seabed rights and the detailed terms on which developers will be expected to bid.
CNSOER subsequently launched the Call for Information (NS25‑1R) and Prequalification (NS25‑1R) (https://cnsoer.ca/news-resources/news-announcements/offshore-wind-call-for-information-and-prequalifcation-ns25-1R), which ran from October 2025 to 13 January 2026, with the first Call for Bids anticipated during 2026. Designation of Wind Energy Areas is not, however, a construction approval and future Call for Bids areas within the designated Wind Energy Areas will need to be determined through subsequent land-tenure steps and any successful bidder will still need to obtain project-specific environmental and regulatory approvals before construction can proceed.
The consultation record also foreshadows issues that are likely to carry into the first leasing round. The governments reported around 150 submissions from commercial fishers, Indigenous groups, prospective developers, environmental organisations, federal departments, local businesses and members of the public, with feedback generally supportive of offshore wind but raising concerns around conservation areas, aquatic species, commercial fishing, existing ocean uses and proximity to shore.
Revenue framework
In February 2026, Nova Scotia introduced the Powering the Economy Act and established a statutory offshore wind revenue framework through the Offshore Renewable Energy Revenue Act. This gives the Province an identifiable fiscal framework for offshore wind licences but does not by itself resolve the separate question of how projects will secure long-term contracted export revenues.
Provincial communications describe:
- a refundable bid fee of C$250,000;
- a non-refundable licence fee of C$750,000 for successful bidders; and
- an annual capacity levy of C$7,000 per MW for the first 10 years of operations.
From year 11 onwards, Nova Scotia may either continue the capacity levy or apply a revenue-based levy, to be set by regulation and reflecting a percentage of gross revenue, structured so that the greater of the capacity levy and the revenue-based levy can apply. The long-dated nature of offshore wind assets means that this post-year-10 mechanism will be relevant to equity valuation, debt sizing and sensitivity analysis, even if it does not affect the first decade of operations.
For developers and lenders, the first-decade levy provides some near-term visibility, but the post-year-10 fiscal mechanism remains an important sensitivity for valuation and debt sizing. Bidders will therefore look for further detail on levy caps, calculation methodology, stabilisation, change-in-law treatment and the interaction between licence payments, offtake revenues and transmission availability.
The design of the fiscal regime will also interact with tender competitiveness. If fiscal payments are not appropriately calibrated against export revenue certainty and transmission deliverability, developers may price the risk into bids or defer participation until the route to market is clearer. Conversely, predictable and bounded fiscal exposure could help Nova Scotia convert strong resource fundamentals into more competitive bid pricing.
Transmission and system integration
Transmission is the central structural issue for Wind West. The programme anticipates substantial interprovincial and/or cross-border transmission development, but the delivery model, ownership structure and cost allocation for transmission infrastructure all remain open. That issue is more fundamental than a conventional grid-connection question: an export-led strategy requires coordination between offshore collection systems, landfall, onshore upgrades, interconnectors, export-market requirements and the procurement or contracting framework that will underpin revenues.
Absence of a clearly articulated transmission framework increases interface risk, raises the likelihood that developers bear significant delivery and cost risk and complicates project financeability for both generation and export assets. A generation project that is otherwise technically viable may not be financeable if transmission capacity, export rights, commissioning interfaces or curtailment arrangements are not sufficiently settled at bid stage.
The sequencing of transmission decisions relative to seabed leasing and project development milestones is therefore likely to be a key determinant of competitive tension in the first Call for Bids and the pace at which projects can reach financial close. Developers will want to understand whether transmission is expected to be government-led, utility-led, jointly developed, separately procured or integrated into generation bids and how delay, interface and cost-overrun risks will be allocated.
The site economics reinforce the point. Aegir’s value mapping includes distance to grid and construction port among the key Levelised Cost of Electricity (LCoE) drivers and notes that the current high-voltage grid is concentrated in limited coastal locations, with additional potential connection points modelled at Goldboro and Port Hawkesbury. As a result, even areas with strong wind speeds and favourable water depths may require significant transmission investment before they can be converted into financeable export projects.
Route-to-market developments
Nova Scotia has indicated that early offshore wind output is expected to be exported rather than sold into the domestic Nova Scotia market. Developers will need credible export buyers, transmission pathways and long-term revenue arrangements before projects of the scale contemplated by Wind West will become financeable.
On 4 February 2026, Nova Scotia and Massachusetts signed a Memorandum of Understanding on Offshore Wind Energy and Infrastructure Collaboration (https://novascotia.ca/offshore-wind/docs/memorandum-of-understanding-offshore-wind-energy-infrastructure-collaboration.pdf). The MOU is non-binding but signals political intent to explore delivery pathways, grid integration and supporting infrastructure and is an early indication that Nova Scotia is seeking to align Wind West with demand in neighbouring US markets.
In March 2026, Hydro‑Québec issued a Request for Information to assess options for the supply and transmission of electricity generated by offshore wind farms off Nova Scotia (https://news.hydroquebec.com/news/press-releases/all-quebec/hydro-quebec-launches-request-information-inform-potential-development-offshore-wind-farms-off-nova-scotia.html), noting that no investment or procurement decisions had been made at that stage. The RFI is nevertheless strategically relevant because it tests whether a major Canadian utility could form part of the export route-to-market or transmission solution.
Nova Scotia’s Premier publicly linked Hydro‑Québec’s RFI to Wind West and characterised early buyer interest as reducing market uncertainty and strengthening the investment case. Translating current engagement into firm, long-term cross-border PPAs, utility procurement arrangements or other contracted revenue structures, together with associated transmission solutions, remains a critical dependency.
For future bidders, key questions will include whether offtake is expected to be secured before or after seabed award, whether export contracts will provide fixed or indexed pricing, how curtailment and transmission non-availability are treated, what credit support will be available and whether any public-sector support will be available to bridge the gap between early-stage market engagement and bankable revenue certainty.
Comment
Wind West has progressed rapidly from concept to structured policy programme. Nova Scotia now has designated wind energy areas, an active pathway towards leasing, a statutory revenue framework and early engagement with possible export markets. It also has a strong underlying resource proposition, with high wind speeds, although site-specific constraints will need to be assessed carefully as the leasing process moves from policy design to project development.
However, the regime remains at a stage where policy architecture is more advanced than commercial implementation. In particular, delivery of a credible transmission solution, conversion of market signals into bankable offtake and long-term fiscal clarity will determine whether Wind West can attract global capital at scale and convert policy momentum into financeable projects. The first Call for Bids will be the first real test of whether Nova Scotia can turn a compelling resource narrative into investable project terms.
