For many organisations, CHP is the measure that offers the most significant single opportunity to reduce energy costs and to improve environmental performance with existing users of CHP typically saving around 20% of their energy costs<ref name='chp1' />.

The heat generated during this process is supplied to an appropriately matched heat demand that would otherwise be met by a conventional boiler<ref name='chp1' />.

The consequence of cogenerating heat and electricity is that the electricity generated is reduced. Therefore, a compromise is needed to be made considering the specific heat and electricity demand, the economic value of each, and the incentives in place to support CHP generation when establishing how a CHP plant will operate<ref name='chp2' />.
