Thermal efficiency is the efficiency with which heat energy contained in fuel is converted into electrical energy. The values displayed were calculated on the gross calorific value basis, also known as higher heating values (HHV).
The thermal efficiency of nuclear power stations in the United Kingdom has remained relatively stable over the years. In 2022, nuclear power stations had a thermal efficiency of 39.7 percent. Thermal efficiency is the efficiency with which heat energy contained in fuel is converted into electrical energy.
