This document discusses the demonstration of RES visualisation software that can visualize entire or parts of reference energy systems (RES) models to help with debugging and stakeholder engagement. The software was initially created for ANSWER-MARKAL in 2011 and has since been developed for VEDA-TIMES models with ETSAP funding. The beta version is being demonstrated today and feedback is welcomed to further develop the tool for the ETSAP community by the end of 2016.
