In collaboration with the (Ireland) and we are developing , an open-source and open-data model generator. OSeMOSYS Global can be used to create inter-connected energy system models for the entire globe or for any geographically diverse subset of the globe. Built using the open-source energy modelling system, , it is fully configurable by the user in determining the modelling detail and geographic scope. The configurable workflow and full energy model representation allows policy makers to evaluate long-term energy policy decisions at both a country/regional level and at a global level.
