Standard CFD Fuel Measurement and Sampling Questionnaire
Before completing this document, ensure you have read the Contracts for
Difference (CFD) Fuel Measurement and Sampling (FMS) Guidance Note.
Overview
The submission of this document forms part of the FMS Proposals Notice for
fuelled Generators that have entered into a Contract with the Low Carbon
Contracts Company (LCCC). It can also be a useful point of reference for early
FMS discussions with Ofgem prior to the submission of the FMS Proposals Notice.
Generators using fuels at their Facilities are required to undertake the FMS
Procedures detailed within this questionnaire for each Renewable Qualifying
Multiplier (RQM) calculation month.
These FMS Procedures produce the data used to determine the RQM, and help
fulfil the requirements for reporting information on the sustainability of fuels.
Unless otherwise provided for in the CFD, complete all the sections of the FMS
questionnaire. Depending on your answers to certain questions, you will be
instructed to skip to different questions. Compulsory questions are marked with a
 symbol. If a question is not relevant to your Facility, please put N/A in the
answer field.
Questionnaire
Completion
FMS Exempted Procedures for Facilities using fuels with non-Variable Renewable
Content or Qualifying Waste should be outlined in Section D. To account for
instances where the FMS Exemption Criteria are not met (even if this is unlikely),
Full FMS Procedures should be outlined in the rest of the FMS questionnaire.
You should complete different questionnaires for fuels with different FMS
Procedures. For example if two fuels are used at a Facility, one a liquid biomass
and one a solid biomass, then different questionnaire documents must be
submitted for each.
When completing this questionnaire, clearly outline how you will undertake your
procedures. The size of the response text box indicates the length of answer
expected. There is extra space for your answers in section J if required.
Questionnaire
Submission
When referencing any industry standards include the name, issuing body and
reference number of the standard.
Your questionnaire will form part of the FMS Proposals Notice to LCCC. This will
then be referred to Ofgem who, as agents of LCCC, will contact you with an initial
set of comments about your procedures once we have reviewed your
questionnaire. From this point forward, updated versions can be submitted to
Ofgem via the [email protected] inbox, according to the timelines specified in
the contract.
Ofgem strongly recommends that you make contact to discuss the FMS
Procedures, before submitting an FMS Proposals Notice to LCCC. We will work
with Generators who have been awarded a contract and review draft FMS
questionnaires prior to the submission of an FMS Proposals Notice to facilitate a
more convenient process towards the consent of the FMS Procedures.
