This paper provides insights into the implications of a global coal phaseout in the power generation sector across different regions under international climate targets. Using modelled scenarios, we highlight the strong rate of decline in new build and decommissioning of existing coal assets, and the growth in renewable capacity to not only fill the gap but meet growing demand for electricity. We find that key uncertainties exist across many of these pathways towards system decarbonisation. We also explore how regionally connected grids can help in transitioning away from coal whilst ensuring supply of electricity. Focusing on potential interconnection between India and the Gulf region, we find that this can be an important strategy for helping enable the transition based on increasing renewables, with regional interconnection encouraging coal phase-out even without a specific coal phase-out target. The technical modelling in this report requires further consideration, in respect of the other multiple benefits of a transition towards low carbon generation, but also the policy mechanisms that will enable delivery of what is a hugely challenging transition.
