The Global Energy System Model (GENeSYS-MOD) is an open-source energy system model, originally based on the Open-Source Energy Modeling System (OSeMOSYS) framework. While still part of the OSeMOSYS family of models, various aspects have been redesigned, expanded, or added. GENeSYS-MOD is a linear program, minimizing total system costs. Energy demands are exogenously predefined and the […]

Case Study 5 Impact of decentralization of investment decisions in power systems

OpenEntrance Case Study 5 The main issue of case study 5 (CS5) is to evaluate the impact of decentralization of investment decisions compared to centralized decisions on power systems. More specifically, the centralized framework is viewed here as the least cost case and is considered as a baseline. All resources are supposed to be exploited […]


The peer-to-peer electricity trading model FRESH:COM developed by TU Wien is part of the case study “Behavior of communities of actors” within the H2020 project openENTRANCE. The model was transformed to an open-source model during the project. It is now publicly available on GitHub at implemented in Python. The linear optimization model perfectly allocates […]

Gusto, TU Wien

The GUSTO model is an open-source model (OSM) optimizing the energy technology investment (portfolio decision optimization) and the technology dispatch on a local level. It is an extension of the existing OSM urbs. The expansion of the model’s framework includes additional features and functionalities. Hence, the model is tailor-made for analyzing local energy systems such as […]

openTEPES, Comillas

The Open Generation and Transmission Operation and Expansion Planning Model with RES and ESS (openTEPES) determines the investment plans of new facilities (generators, ESS and lines) to supply the forecasted demand at minimum cost. Tactical planning is concerned with time horizons of 10-20 years. Its objective is to evaluate the future generation, storage and network […]

Integrate, SINTEF

Integrate is an optimization model for planning of local energy systems where different energy carriers and technologies are considered simultaneously. The model gives the user a graphical overview of a given energy system (e.g. municipality, city, suburb) with respect to costs, environmental consequences and use of local energy resources. The current version can optimize the […]


EXIOMOD is an economic model able to measure the environmental impact of economic activities. As a multisector model, it accounts for the economic dependency between sectors. It is also a global and multi-country model with a consistent trade linking between countries at the commodity level. Based on national account data, it can provide compressive scenarios […]


EMPIRE is a comprehensive power system model including generation, storage, and transmission capacity expansion. It is designed to determine optimal capacity investments under operational uncertainty, while also incorporating long- and short-term dynamics.To achieve these objectives, EMPIRE is a stochastic linear program endogenously considering uncertainty on an hourly operational resolution of (1) nationally aggregated load and […]


REMES is a Computable General Equilibrium model that represents the Norwegian economy with a particular focus on the energy system. REMES is used to study the effects of macroeconomic policies on the Norwegian economy. The model splits the national economy into five regions, which coincide with the five Norwegian energy market zonal prices. It includes 36 […]
