A load consumes energy from the microgrid. A primary load can model anything that uses electricity, such as a light bulb or a motor. A thermal load can represent anything that uses heat energy, such as a heating system or an absorption chiller. A deferrable load consumes electricity on a flexible schedule and can model systems that need a certain amount of energy over a given period, but don't need power at specific times. A hydrogen load can model a consumer of hydrogen, such as a fuel cell or a chemical process.
