North American Times Energy Model

NATEM is the only economy-wide optimization energy system model for net-zero scenario analysis. It describes the entire integrated energy system, as well as non-energy emitting sectors of North American jurisdictions, and provides a rigorous analytical basis for identifying least-cost solutions to achieve energy and climate objectives without compromising economic growth. It can be used as a standalone model or with NAGEM.

A powerful decision-making tool

NATEM enables capturing substitutions of energy forms (e.g., switching to low-carbon fuels) and technologies (e.g., use of battery electric vehicles instead of internal combustion engine vehicles) to both meet demands and comply with policy targets.

NATEM can be used to derive minimum cost solutions for meeting prescribed GHG reduction targets in selected jurisdictions under different combinations of premises.

It can be used to derive projected GHG reductions in response to defined policy frameworks. The inherent flexibility with NATEM provides a large range of energy and climate policy-relevant investigations.

NATEM model’s results have been used by decision makers from public and private organizations to:

  • Draft climate action plans with sequencing of options
  • Prepare technological roadmaps
  • Identify and analyze energy security issues
  • Prepare outlooks with net-zero scenarios
  • Evaluate the economic and environmental impacts of energy projects
  • Identify strategic research priorities to reduce mitigation costs and contribute to economic development

Detailed representation of North American energy systems

NATEM follows a techno-economic modelling approach to describe the energy systems of North American jurisdictions through a large variety of specific energy technologies characterized with their technical and economic attributes as well as pollutant coefficients. It offers a detailed representation of an energy sector, which includes extraction, transformation, distribution, end uses, and trade of various energy forms and materials.

NATEM distinguishes between generation technologies that convert primary energy into secondary energy (e.g., refineries, power plants, etc.) and end-use devices that transform final energy into energy services (e.g., cars that serve a demand for mobility, light bulbs that serve a demand for lighting). In particular, they include existing technologies, improved versions of the same technologies and emerging technologies, all characterized by their technical and economic attributes. Consequently, it allows for detailed accounting of all energy flows within the energy sector from primary energy extraction to final energy consumption.
