A plant facilitating the generation of electrical power and recovery of usable heat from a combustion process is termed a Combined Heat and Power (CHP) plant and it is more efficient than conventional power generation that is focused on power generation alone. | A plant facilitating the generation of electrical power and recovery of usable heat from a combustion process is termed a [[Combined Heat and Power]] ([[CHP]]) plant and it is more efficient than conventional power generation that is focused on power generation alone. | ||
Heat is produced as a by-product when generating electricity through the combustion of a fuel. The utilisation of this heat can significantly increase the efficiency of a power plant. By generating heat and power simultaneously, CHP can reduce carbon emissions by up to 30% compared to the separate means of conventional generation via a boiler and power station, making use of the heat which would otherwise be wasted when generating electrical or mechanical power<ref name='chp1'>Department for Business, Energy & Industrial Strategy, 2019.

Many CHP Energy from Waste [[EfW]] plants are built ‘CHP ready’ but without a viable heat customer in close enough proximity and therefore operate in the less efficient mode of producing solely electricity<ref name='chp2' />. | Many CHP Energy from Waste [[EfW]] plants are built ‘CHP ready’ but without a viable heat customer in close enough proximity and therefore operate in the less efficient mode of producing solely electricity<ref name='chp2' />. | ||
