User:Engineman/Power generating equipment efficiency and carbon footprint

This article is devoted to providing a comprehensive list of electrical power generating equipment efficiencies and other basic paramaters such as start up times, intalled coss, and carbon footprint etc clearly stating the criteria and conventions used.

Efficiency
Efficiency means ( for the purposes of this article ) the Gross (ie power measured at the generator terminals less own use power. Note on large stations all power is often exported from the generators, but works power is often imported separately at a lower voltage and this must not be neglected) electrical power output, divided by the fuel input measured using the Lower Calorific Value convention (ie the heating value of the fuel minus the latent heat of vaporisation of any steam in the fuel). The tables show peak steady state efficiency and actual in service / seasonal efficiency which will typically be less due to cycling losses and part loading.
