The North American TIMES Energy Model (NATEM)

Learning from all previous energy modeling experiences (Projects)ESMIA consultants benefit from having built their own modeling platforms.

The NATEM platform allows multiple analyses of energy issues and strategic decision-making at multiple levels of geographical disaggregation. The platform is built in a flexible manner allowing for 1) extraction of a region from of a wider geographic area facilitating small scale and sector specific analysis and 2) aggregate geographic regions for more comprehensive large-scale analyses. Each model can be used in a soft-linking or hard-link mode with other models.

All ESMIA models have been developed using the most advanced optimization modeling framework: The Integrated MARKAL-EFOM System (TIMES). The MARKAL/TIMES model generators are supported by ETSAP – Energy Technology Systems Analysis Program of the International Energy Agency (IEA) and currently used by more than 80 institutions in nearly 70 countries.

NATEM-Quebec. Extracted from the NATEM- Canada model, NATEM-Québec was initially designed for prospective life cycle analysis (LCA) of agricultural sectors. With already with 9 categories of demand for agricultural products, 400 transformation processes and 90 commodities, the agricultural sector were completed to incorporate all inputs-outgoing relationships (raw materials, energy flows, solid, gaseous, liquid wastes, co-products) at all stages of the LCA. Each sector can be disaggregated for any sector specific analysis or local energy planning.

Spatial : A single region « Quebec », with data disaggregated by sub-regions 

Temporal : 2011-2050, 9 time periods and 16 annual time slices (4 seasons et 4 intraday periods).

NATEM- WEST Canada. Extracted from the NATEM-Canada model, NATEM-WEST Canada was initially created to fill the need for a very comprehensive framework for performing studies on optimal GHG mitigation strategies. Indeed, as a significant energy producer and exporter, the four provinces of the Western Canada Sedimentary Basin (WCSB) face challenges that need to be addressed in a particular manner to the benefit of the whole Canadian economy: meeting growing energy demands and expanding the energy sector while reducing GHG emissions.

Spatial: 4 regions corresponding to the 4 provinces of Western Canada.

Temporal : 2011-2050, 9 time periods and 16 annual time slices (4 seasons et 4 intraday periods).

NATEM-Canada. The recent version of NATEM-Canada is the most advanced optimization and multi-regional model covering in details the large diversity of Canadian energy systems on a long term horizon (up to 2100). Energy balances have all been calibrated to the 2011 base year. All databases are regularly revised and updated using the most recent data sources. Constant development allows advanced features to be implemented and databases to be refined.

With a particularly high level of detail despite the size of the geographical coverage, NATEM-Canada is an important module of the North American modeling platform NATEM. The model is particularly suitable to address any relevant Canadian challenges: renewable energy development in remote areas, penetration of intermittent energies in the grids, energy storage, domestic trade, unconventional oil & gas exploration and production, coal phase-out, electrification of transportation, biofuel regulations, carbon capture and sequestration projects, potential and effects of energy savings, GHG mitigation strategies (carbon markets or taxes), etc.

Spatial: 13 regions corresponding to the 13 Provinces and Territories of Canada 

Temporal : 2011-2050, 9 time periods and 16 annual time slices (4 seasons et 4 intraday periods).

NATEM. The NATEM model represents the heart of the platform. It is a technology rich, multi-regional and integrated energy model that covers in detailed format the energy systems of Canada, United States and Mexico. The model comprises 23 geographical regions having their own reference energy system (RES), but linked together through energy, material and emission permit flows.

In maintaining the same stringent levels of detail as is found in the NATEM-Canada model, NATEM also allows for the capture on endogenous energy trade movements within the North American markets.

Due to their geographical location and common border, Canada and the United States face many opportunities and challenges that justify deeper analysis: producing synthetic oil or exporting bitumen, interconnection projects between Quebec/Atlantic provinces and North East States, pipeline projects between Western Canada and USA, etc.

Spatial: 23 regions, including 13 Canadian regions, 9 American regions, 1 Mexican region

Temporal : 2011-2050, 9 time periods and 16 annual time slices (4 seasons et 4 intraday periods).

Global scale

map GLOBAL

NATEM-Global. NATEM-Global is the North American 23 region model linked to an extra global module accounting for rest of the world energy demand and supply.

Benefiting from abundant energy resources, Canada is one of the largest energy producers and exporters in the world. While energy exports were mainly destined to the USA, energy producers are more and more trying to diversify their markets beyond North America to sell their growing oil production and secure their export revenues. The link with a global module allows analyzing the interactions with other markets.

Spatial: 24 regions, including 13 Canadian regions, 9 American regions, 1 Mexican region and 1 Global region (Rest of the World).

Temporal : 2011-2050, 9 time periods and 16 annual time slices (4 seasons et 4 intraday periods).
