3.2 Energy calculations Various turbine designs have varying efficiencies and therefore varying power output. If the efficiency of the turbine " Ï" is known the equation below can be used to determine the power output of a turbine. The energy available from these kinetic systems can be expressed as: Where: Ï = the turbine efficiency

The latest high-efficiency turbines are impressive machines. In 2016, when EDF Bouchain deployed a high-efficiency H-Class turbine in a combined-cycle configuration—meaning it recovered waste heat to drive a steam turbine, instead of venting it into the atmosphere—the plant achieved 62.22 percent net efficiency, according to GE Power.
