Heat rate (efficiency) Heat rate (efficiency) Heat rate is a term commonly used in power stations to indicate the power plant efficiency. The heat rate is the inverse of the efficiency: a lower heat rate is better. formula_1 While efficiency is a dimensionless measure (sometimes quoted in %) heat rate is typically expressed as Btu/kWh. This is because Watt-hours are more commonly used when referring to electrical energy and Btu is more commonly used when referring to thermal energy. Heat rate in the context of power plants can be thought of as the input needed to produce one unit of output. It generally
