China has made some significant medium and long-term climate commitments, including to peak carbon emissions by 2030 and achieve carbon neutrality by 2060. These imply a massive shift in the direction of an economy that is still building coal plants and growing its fossil fuel use. Wind and solar installations will likely need to exceed 100 GW per year for decades. In this talk, we will explore the implications of meeting these long-term targets on planning and operations in the power sector. Rapid expansion of intermittent renewables can lead to excessively high curtailment rates without broader reforms to power sector institutions. Markets and business models for thermal power plants must adapt to changing demands from a system flexibility perspective. The development of transmission and distribution infrastructure will shape the available options to scale up low-carbon energy. We will go beyond the numbers to discuss what technologies and policies are really necessary, what are nice to have, and what are just red herrings.
