  Energy system models underpin decisions by energy system planners and
operators. Energy system modelling faces a transformation: accounting for
changing meteorological conditions imposed by climate change. To enable that
transformation, a community of practice in energy-climate modelling has started
to form that aims to better integrate energy system models with weather and
climate models. Here, we evaluate the disconnects between the energy system and
climate modelling communities, then lay out a research agenda to bridge those
disconnects. In the near-term, we propose interdisciplinary activities for
expediting uptake of future climate data in energy system modelling. In the
long-term, we propose a transdisciplinary approach to enable development of (1)
energy-system-tailored climate datasets for historical and future
meteorological conditions and (2) energy system models that can effectively
leverage those datasets. This agenda increases the odds of meeting ambitious
climate mitigation goals by systematically capturing and mitigating climate
risk in energy sector decision making.
