Orderly retire China's coal-fired power capacity via capacity payments to support renewable energy expansion

Summary: The energy-only-market implemented in China cannot strongly support large-scale renewable energy expansion because the renewable energy expansion may disorderly phase out non-renewable power capacity. However, non-renewable power capacity, particularly the coal-fired power capacity in China...
