Heat rate (efficiency) – Wikipedia
2019-6-6 · 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. = 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

Thermal efficiency – Wikipedia
2019-6-6 · In thermodynamics, the thermal efficiency is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, a steam turbine or a steam engine, a boiler, furnace, or a refrigerator for example. For a heat engine, thermal efficiency is the fraction of the energy added by heat (primary energy) that is converted to net work output (secondary energy).

With that in mind, if you increase plant efficiency, which is good, then you would lower heat rate. What this means is that the lower the heat rate, the better your plant is running and, therefore, the more competitive it is. As you can see by the equations, efficiency has no units, but heat rate does.
