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.
