Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic Canada

Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic Canada Offshore wind represents a potentially significant source of low-carbon energy for Canada, and ensuring that relevant, high-quality data and scientifically sound analyses are brought forward into decision-making processes will increase the chances of success for any future deployment of offshore wind in Canada. To support this objective, CanmetENERGY-Ottawa (CE-O), a federal laboratory within Natural Resources Canada (NRCan), completed a preliminary analysis of relevant considerations for offshore wind, with an initial focus on Atlantic Canada. To conduct the analysis, CE-O used geographic information system (GIS) software and methods and engaged with multiple federal government departments to acquire relevant data and obtain insights from subject matter experts on the appropriate use of these data in the context of the analysis. The purpose of this work is to support the identification of candidate regions within Atlantic Canada that could become designated offshore wind energy areas in the future. The study area for the analysis included the Gulf of St. Lawrence, the western and southern coasts of the island of Newfoundland, and the coastal waters south of Nova Scotia. Twelve input data layers representing various geophysical, ecological, and ocean use considerations were incorporated as part of a multi-criteria analysis (MCA) approach to evaluate the effects of multiple inputs within a consistent framework. Six scenarios were developed which allow for visualization of a range of outcomes according to the influence weighting applied to the different input layers and the suitability scoring applied within each layer. This preliminary assessment resulted in the identification of several areas which could be candidates for future designated offshore wind areas, including the areas of the Gulf of St. Lawrence north of Prince Edward Island and west of the island of Newfoundland, and areas surrounding Sable Island. This study is subject to several limitations, namely missing and incomplete data, lack of emphasis on temporal and cumulative effects, and the inherent subjectivity of the scoring scheme applied. Further work is necessary to address data gaps and take ecosystem wide impacts into account before deployment of offshore wind projects in Canada’s coastal waters. Despite these limitations, this study and the data compiled in its preparation can aid in identifying promising locations for further review. A description of the methodology used to undertake this study is contained in the accompanying report, available at the following link: https://doi.org/10.4095/331855. This report provides in depth detail into how these data layers were compiled and details any analysis that was done on the data to produce the final data layers in this package. 2024-03-01 Natural Resources Canada ceobusinessoffice-ceobureaudesaffaires@nrcan-rncan.gc.ca Nature and EnvironmentClimateRenewable energyRenewable resourcesWindWind energyEnvironmentAssessment Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic CanadaESRI REST https://maps-cartes.services.geo.ca/server_serveur/rest/services/NRCan/Wind_study_considerations_en/MapServer Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic CanadaESRI REST https://maps-cartes.services.geo.ca/server_serveur/rest/services/NRCan/Wind_study_considerations_fr/MapServer Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic CanadaWMS https://maps-cartes.services.geo.ca/server_serveur/services/NRCan/Wind_study_considerations_en/MapServer/WMSServer?layers=1&legend_format=image%2Fpng&feature_info_type=application%2Fvnd.esri.wms_raw_xml&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic CanadaWMS https://maps-cartes.services.geo.ca/server_serveur/services/NRCan/Wind_study_considerations_fr/MapServer/WMSServer?layers=1&legend_format=image%2Fpng&feature_info_type=application%2Fgeojson&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic CanadaFGDB/GDB https://ftp.maps.canada.ca/pub/nrcan_rncan/Energy-supply_Disponibilites-energetiques/Wind-energy_Energie-eolienne/RasterLayers_en.gdb.zip Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic CanadaFGDB/GDB https://ftp.maps.canada.ca/pub/nrcan_rncan/Energy-supply_Disponibilites-energetiques/Wind-energy_Energie-eolienne/RasterLayers_fr.gdb.zip metadata Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic CanadaPDF https://ftp.maps.canada.ca/pub/nrcan_rncan/Energy-supply_Disponibilites-energetiques/Wind-energy_Energie-eolienne/29fd13f3-e7d5-4291-8560-69d405a64a3f_en.pdf metadata Preliminary Considerations Analysis of Offshore Wind Energy in Atlantic CanadaPDF https://ftp.maps.canada.ca/pub/nrcan_rncan/Energy-supply_Disponibilites-energetiques/Wind-energy_Energie-eolienne/29fd13f3-e7d5-4291-8560-69d405a64a3f_fr.pdf
