Integrated optimization model for the exhaustive analysis of energy and climate policies in North America. / Modèle d’optimisation intégré pour l’analyse exhaustive des politiques énergétiques et climatiques en Amérique du Nord.

North American TIMES Energy Model has been used to model all North America in 13 Canadian provinces and territories, 9 USA census region, and 1 Mexican region, plus trade links with rest of the World. The temporal range of this version encompasses 2011-2015 with annual or multi-annual periods and 16 intra-annual time slice (4 seasons; 4 intra-day periods).

It has been applied to draft climate action plans, define optimal sequences for the introduction of mitigation measures, identify strategic research priorities for reducing mitigation costs, prepare Canadian energy outlooks, prepare technology road maps, assess technological penetration rates, assess economic and environmental impact assessments of future energy projects


Output used by decision-makers at different levels of governments (federal, provincial, city levels), industries and associations: Quebec ministry of environment and climate change and Quebec ministry of finance in preparation of the climate action plan: the model was used to identify optimal GHG reduction trajectories for achieving the official targets taking into account uncertainties related to the evolution of demands, social acceptability, and technological innovation (Dunsky et al.,2019), environmental commissioner of Ontario in preparation of its climate action plan: the model was used to compared costs and other impacts for i) achieving Canadian only mitigation targets and ii) achieving both Ontario and Canadian mitigation targets (Vaillancourt et al.,2018d),metropolitan Montreal community (MMC) in preparation of its climate action plan: the model is used in support to the development of an action plan and define priorities in consultation with key stakeholders to achieve carbon neutrality in 2050 (no reference,ongoing project).

At the federal level, the model is used to prepare Canadian energy outlooks including both business-as-usual and deep Decarbonisation scenarios: the most recent Canadian energy outlook (Langlois-Bertrand et al.,2018) with an ambitious scenario including a GHG reduction target of 80% by 2050 compared to 1990; the first of its kind in over a decade covering Canada and its 13 jurisdictions, the previous Trottier energy futures project (TEFP, 2016) is now a reference in Canadian universities and government offices to understand how canada can achieve its official targets.

NATEM is also used to support the private sector and associations with the preparation of technology roadmaps and assessment of technological penetration rates under deep decarbonisation scenarios: a gas company in preparation of its long-term strategic plan 2015-2030: the model was used to analyse the penetration rates of renewable natural gas and liquefied natural gas under mitigation scenarios for achieving official mitigation targets (no reference, confidential project), biofuel Canada network: the model was used to derive market penetration rates of two biofuel pathways (butanol from pulp and paper residues and ethanol from fast-growing trees) to 2050 under GHG mitigation scenarios (Levasseur et al.,2016), Natem is also used to brief governmental decision-makers on the economic and environmental impacts of energy projects and energy security aspects,prime minister office and Quebec ministry of environment and climate change to support its position on the exploitation of hydrocarbon on the Anticosti island: the model was used to assess the impacts of meeting the GHG targets with and without the project (Vaillancourt et al.,2018c), centre for applied research in economics (care): the model was used to evaluate the impacts of the transcanada energy east pipeline on the oil supply-demand dynamic and prices in eastern provinces, Newfoundland and Labrador especially (Vaillancourt et al.,2015), amongst other applications, the model is used to assist decision-makers with the evaluation of circular economy strategies: Quebec ministry of energy and natural resources: the model was used to analyse the techno-economic potential of multiple circular economy strategies for the mining industries, namely with supply chain of iron and steel, copper and lithium (Vaillancourt et al.,2018e)
