A mini combined cycle power plant with a mini gas turbine engine that operates at around 20,000 to 30,000 rpm and is connected to an electric generator through a speed reduction gear box, a low pressure steam turbine connected directly to the gas turbine engine, a high pressure steam turbine connected to the low pressure steam turbine through a smaller gear box so that the high pressure steam turbine can operate at around 70,000 to 100,000 rpm, and a heat recovery steam generator to use the turbine exhaust to produce high pressure steam for the two steam turbines. Leftover heat from the HRSG is used to heat homes or buildings in the local area to the power plant to improve the overall efficiency of the plant.
