China''s new capacity payment risks locking in coal
Coal plants in most provinces will receive a monthly payment of 100 yuan per kilowatt (y/kW) of their capacity. While those in seven provinces with a higher share of low-carbon energy will receive 165 y/kW. These are Henan, Hunan, Chongqing, Sichuan, Qinghai, Yunnan, and Guangxi. (The two rates represents 30% and 50% of 330 y/kW, …

How a Capacity Market Works | Energy Central
The short answer is that capacity markets do not have an inherent resource preference. They acquire the lowest cost resources needed to meet demand. If renewables are the lowest cost, then those would "clear" the market over moe expensive fossil fuels. If a coal plant is cheaper, it would clear instead.
