Energy modelling is key in order to face the challenges of energy transition. There is a wide variety of modelling tools, depending on their purpose or study phase. This article summarises their main characteristics and highlights ones that are relevant when it comes to the preliminary design of energy studies at district scale. It introduces OMEGAlpes, a multi-carrier energy modelling tool to support stakeholders in the preliminary design of district-scale energy systems. OMEGAlpes is a Mixed-Integer Linear Programming (MILP) model generation tool for optimisation. It aims at making energy models accessible and understandable through its open-source development and the integration of energy stakeholders and their areas of responsibility into the models. A library of use cases developed with OMEGAlpes is presented and enables the presentation of past, current, and future development with the tool, opening the way for future developments and collaborations.

The shape of an energy project depends on the available technologies but also on stakeholders' decisions although most energy-support-decision tools only focus on technical issues. This article aims to propose a multi-actor modelling based on stakeholders' objectives and constraints and to apply it on the optimisation model generation tool OMEGAlpes. This modelling aims to help stakeholders to formalise their constraints and objectives and to negotiate them in a multi-stakeholders design process. Two types of stakeholders involved in urban renewable energy project have been highlighted: operators and infrastructure regulators. This modelling has been applied to a simplified collective selfconsumption project.
