is the process of generating electric power from sources of primary energy.
For electric utilities, it is the first process in the delivery of electricity to consumers. The other processes as transmission, distribution, energy storage and recovery using pumped-storagemethods are normally carried out by the electric power industry. Electricity is most often generated at a power station by electromechanicalgenerators, primarily driven by heat engines fuelled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.
