Energy Systems Analysis

The department develops and analyze energy scenarios, develop strategies to reduce greenhouse gas emissions, analyze the composition of energy carriers and analyze possible future technology choices and energy efficiency solutions. ​ We analyze both cost-efficient design and operation of local energy systems, as well as overall analyses with a societal perspective, covering the connection between different energy sectors. ​ ​

We focus on the effect of technology learning, new technologies, behavior aspects, flexibility solutions, new energy carriers, energy storage, sector coupling and political measures. ​Our energy system models are developed in close collaboration with national/local authorities, organizations, private sector (energy and industry), technology experts etc.​ The research group develop and use several types of mathematical models to increase the knowledge base related to the future energy system. 

ESA has broad international collaboration on the long-term energy systems modelling and holds the ExCo membership in the Technology Collaboration Programme IEA-ETSAP ( on behalf of Norway We are also an active partner in the Research Centers for renewable energy (FMEs):

Scenario modeling

IFE does scenario analysis and transition studies that map out different pathways the Norwegian and European energy system could follow over the coming years, focusing on policies, investments, technologies, and other choices that policy makers and other decision makers can influence. Read more

Local  energy system models

IFE performs modelling and analysis of local energy systems, such as week grid areas, communities, buildings, charging stations etc. The modelling provides insight into cost-effective design and operation of the system. We mainly use short-term energy system models, focusing on the optimal competition and interplay between energy carriers and technologies within the system. Read more.

National and international long-term energy system models

IFE works with long-term energy system models at a local, national and international level, focusing on cost-optimal investments and operation to meet the future energy demand at least cost. Read more.
