SWITCH-China: Open Source Model for the World Largest Power System

Open model to study China’s clean power transition

SWITCH-China Open Model

SWITCH-China Open Model


China’s power sector in 2022 accounted for about 1/4 of global coal consumption, 1/8 of global energy related carbon emission, and at the same time, 40% of global solar and wind capaicity. This fast transiting sector is under pressure to lower its carbon emissions while strive to power the world’s largest manufacturer and fastest growing mid-class. The scale and scope of China’s clean power transition is unprecedented and its impacts are enormouse, yet its trojactories are uncertain. How can China’s power sector achieve carbon netrality will in large impact how can the world meet the net-zero goals. Modeling China’s power transition is both important and challenging. After years’ efforts, and collaboration, I decide to open-source SWITCH-China Model and make it SWITCH-China Open Model to facilitate the modeling integration and comparison, data sharing, policy discussion and debate.
