Peaking power plant

OverviewTypesPeak hoursRenewable energyBase load power plants

Peaker plants are generally gas turbines or gas engines that burn natural gas. A few burn biogas or petroleum-derived liquids, such as diesel oil and jet fuel, but those are generally more expensive than natural gas, so their use is limited to areas not supplied with natural gas. In addition to natural gas, many peaker plants are able to use petroleum as a backup fuel, storing oil in tanks on site. The thermodynamic efficiency of
