23. ROCS AND CFD QI DEFINITIONS. ROCs
For Schemes that have been certified previously and prior to 1 January 2016 on the basis of an F3 submission, the QI formulae in Table 2 of Issues 4 and 5 of Guidance Note 44 (GN44) will continue to be used for certification in 2017. (These formulae are also reproduced as Table A2 of GN44 Issue 6.)
However, the QI formulae in earlier issues of Guidance Note 44 and associated fuel categories will continue to apply to Schemes that were in operation or that can demonstrate they reached financial close, prior to 26 July 2012. These earlier QI formulae are reproduced as Table 3 of GN44 Issue 4 and as Table A1 of GN44 Issue 6.
For those Schemes that have not previously been certified under CHPQA or were certified for the first time between 1 January and 31 December 2016 on the basis of an F3 submission, the QI formulae in Table 2 of GN44 Issue 6 must be used for certification/re-certification in 2017.
CFDs
Operators of Schemes intending to use CHPQA in connection with any ‘with CHP’ CFD entered into, or to be entered into, on or after the date of the publication of Guidance Note 44 Issue 6, i.e. 21 October 2016, should use the relevant QI formula in Table 2 of GN44 Issue 6, irrespective of whether the Scheme has previously been certified on the basis of any other QI formula.
Operators of Schemes for which a CFD contract was entered into prior to the publication of GN44 Issue 6 should use the relevant QI formula in Table 2 of GN44 Issue 5 (reproduced as Table A2 of GN44 Issue 6), irrespective of the date of any previous or likely future CHPQA certification.
See GN44 Issue 6 for further information.
If your Scheme uses a mixture of fuels, you must calculate a weighted average QI definition using fuel fractions calculated in Part 3 section 8.
