Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what evaluation his Department has made of the overall efficiency of a combined heat and power plant.

Combined heat and power (CHP) plants use a range of technologies, which can offer efficiency savings of up to 30% compared to the separate generation of heat and electricity. Their efficiency varies depending on the particular technologies used and how they are operated. The CHP Quality Assurance Scheme assesses plants’ energy efficiency to ensure all those benefitting from government support meet a minimum level.
