Types of power plants Steam turbine. Most traditional power plants make energy by burning fuel to release that reason, they're called thermal (heatbased) power plants. Coal and oil plants work much as I've shown in the artwork above, burning fuel with oxygen to release heat energy, which boils water and drives a steam basic design is sometimes called a simple cycle.
