CHPQA - Quality Assurance for Combined Heat and Power

The CHPQA Standard document is available as a PDF file The CHPQA Standard is the formal document setting out the CHPQA methodology, definitions, thresholds, and criteria for Good Quality certification. It closely follows the Government's consultation response issued on 4 July, but a number of changes have been made to simplify the terminology used. This is intended to make the understanding and application of CHPQA as simple as possible, and to reduce the cost burden of compliance (all strong messages received in response to the consultation). For instance, the Standard uses the words 'heat' and 'power', where before terms included 'electricity', 'generation', 'thermal' etc. Not only is this simpler, it is also in keeping with the name of the technology - Combined Heat and Power. Thus, what was called Electrical Efficiency is now Power Efficiency, and Equivalent Capability has become Qualifying Power Capacity. In addition, all terms relating to energy monitoring have been rationalised (e.g. Equivalent Fuel Input and Equivalent Generation Limit are now called Qualifying Fuel Input and Qualifying Power Output, respectively). All other terms are consistent with this approach.

CHPQA - the Government’s decisions following consultation This document supercedes the pre-publication version issued 4 July 2000. Full details are available as a PDF: Issued 31 July 2000

CHPQA Consultation - the DETR’s draft proposals The consultation paper set out and invited comment on proposals for a CHPQA programme for existing and future CHP schemes. The aim of the process was to consult on the technical detail of how the programme should be implemented. Full details are available as a PDF: Issued January 2000
