2 Instruction sheet FMS questionnaire Purpose This spreadsheet is for generating stations to use when submitting fuel measurement and sampling (FMS) procedures to Ofgem for agreement for the issue of Renewables Obligation Certificates (ROCs). For more information on this, please see the Fuel Measurement and Sampling guidelines available on our website, When a questionnaire should be completed or revised We expect to see FMS procedures or revised FMS procedures when a generator is: applying for preliminary accreditation; applying for accreditation; using a new type of fuel at an existing accredited generating station; or changing procedures for measurement (for example, if new equipment at the station makes it easier to measure using a belt weigher rather than a weighbridge). For more information on this, please see Chapter 3 of our FMS guidelines. What a questionnaire should be completed for A spreadsheet can be completed for one generating station or several generating stations operated by the same company. If more than one procedure is used at a generating station or by a company, all the procedures used should be included and this can usually be achieved on one spreadsheet. The spreadsheet can accommodate up to seven different procedures. The structure of the questionnaire This spreadsheet has nine worksheets including the instructions. These are: The summary worksheet for general information applicable to all stations. Seven procedure worksheets for information relating to each procedure for the measurement and sampling of a type of fuel. The summary worksheet This worksheet contains three parts: Generating station details this should be completed for each generating station the procedures in the spreadsheet relate to. Revision history - each time a generator revises their procedures they should write the reason in the revisions box. Fuels used fuels for which a procedure is submitted will update automatically from the procedures worksheets. Any additional fuels including fossil fuels will need to be added into this worksheet.

3 The procedures worksheets: Each procedure should be completed on a separate worksheet. These worksheets are split into two sections. 1. Fuels/General information 2. Fuel Measurement & Sampling Arrangements Section 2 is then split into two sections and seven parts a g. Please give detailed answers to the questions as this will reduce the need for supplementary questions, thus making the process more efficient. Many of the questions are broken down into two parts. The first is a restricted answer and the second part asks for a further explanation. Where this is the case an example of the information that will be useful is generally given. For information on good practice at other stations, please see Appendix 3 and 4 of the FMS guidelines. The numbering in the tables in these appendices corresponds with the numbering in this questionnaire. The questions in the spreadsheet reflect the questions in Appendix 5 of the FMS guidelines. Some of the questions are broken down further, to allow for brief answers to be given in drop down boxes. Question number 1.3 is missed out on the procedure worksheets. This is because this question is answered on the summary worksheet. Answering the questions (using excel) Protection: Please complete all your answers in the blue cells. The spreadsheet is protected but you will be able to adjust the size of the rows. The rows should increase as you write, if not you can click on the row number to the left of the screen and drag down to the width you want. Long answers: Each cell can contain up to 255 characters. If you have a long answer to a question you may find you exceed this, if so, where a question has more than one row in which to write, continue writing in the row below. Where you run out of rows please use the continuation sheet at the bottom of each procedures worksheet. Please make clear the number of the question you are continuing. Restricted answers: Some questions have a restricted number of answers. These can be identified as a grey box with a downward arrow will appear when the cell for the answer is selected. To select an answer, click on the arrow and choose the relevant option. Additional information: A further explanation of a section or question can be found wherever a small red triangle is shown in the top right hand corner of a cell. To see the explanation hover your cursor over the cell. Who to contact:

4 Procedure 1 Crouchland Farm Biogas Plant Section 1: Fuels/General information 1.1 Which fuel(s) does this fuel measurement and sampling procedure relate to? Anarobic Digestion fuel all types includes cow slurry, cow manure, grass & maize silage, cereal & cereal screenings. What type of fuel(s) are these? Solid 1.2 Please give details of the supplier(s) of the fuel- including name(s) and address(es). This information should be supported by evidence described in paragraph 3.3 of the fuel measurement and sampling guidance. Copies of relevant extracts from the fuel supply contracts should include details of the fuel, energy content and the duration of the contract clearly marked. Produced on generator owner's farm 1.4 How will you make sure that your monthly ROC claim doesn't include any biomass burned which does not result in the generation of electricity? For example, if the generating station is on hot standby, being tested or there is a cancelled start it is likely that electricity has not been generated. No measurement required - explanation given below Further explanation eg what prevents the use of biomass during start-up or how biomass is measured. Anaerobic digester - no contaminated fuels are used

5 Procedure 1 Section 2: Fuel measurement and sampling arrangements a) Weight or volume 2.1 When is the weight or volume measurement taken? Other - explained below Further explanation eg where the flow meter is installed before combustion or if weight is measured offsite where it is measured. Standard figures for slurry production are used to calculate amount of slurry added per day. Other fuels are put through a solid feeder with weigh cells and will be added to the digester over a 24hr period - followed by the same again the following day 2.2 How is the weight or volume measured? Other - explained below Further explanation eg accuracy of weighbridge/belt weigher and/or how a stock level calculation is done. Standard figures for slurry production are used to calculate amount of slurry added per day. Other fuels are put through a solid feeder with weigh cells and will be added to the digester over a 24hr period - followed by the same again the following day 2.3 How often is the weight or volume measured? Other - explanation below Further information. Standard figures for slurry production are used to calculate amount of slurry added per day. Other fuels are put through a solid feeder with weigh cells and will be added to the digester over a 24hr period - followed by the same again the following day 2.4 How do you manage the requirement to measure accurately fuel in the month it is burned? This is a particular issue if any of the biomass fuel delivered in a particular month is being carried over to be burned in a different month. Other - explained below Further information. Slurry will not be measured but will be xxxxx constant. Other fuels will be weighed in and logged. Only as it is put into the solid feeder will it be logged. On average the substances remain in the digester for 100 days during the process of digestion and it would be noted that what is put in the digester is not fuel but the means of making fuel. 2.5 If the weight or volume measurement(s) meets any UK, European or other standard(s) (e.g. BS, ISO, CEN), please give details. I don't know 2.6 Is any method of verification of the measurement used? no Further explanation eg what the method of verification is. But the weigh cells in the soild feeders will be checked regularly

6 Procedure 1 b) Gross Calorific Value 2.7 When are representative samples taken? Other - explained below Further explanation eg at what point samples are taken from before combustion or if a sample is taken offsite where it is taken. The gross calorifc value of separate ingredients will not be calculated. Our aim within the primary and secondary digester is to produce enough methane gas to run our engine continuously at 1000kW output. We have an ongoing relationship with Biogas Nord, who are building the plant, for advice in maximising output. This can be achieved in a number of ways - slight latering of the temperature in the tanks, changing agitation frequency and directives and juggling with the feedstocks to achieve the desired result. all slurry and cow manure will be digested but tonnages of others will be on a as and when basis to achieve maximum output. 2.8 How is the representative sample taken? Other - explained below Further explanation including how you ensure that the sample is representative of the fuel it's taken from. Samples of substrate will be taken monthly, more often at start up, and analysied in a laboratory by Biogas Nord and advice fed back to us on maintaining a stable digestive process. The substrate is agitated regularly and so is well mixed. 2.9 How often is a sample taken? Once a month Further explanation eg if a composite sample is taken, how many deliveries the generating station generally gets each month How do you ensure that the GCV is representative of what is being burned? How do you ensure carry-over is included in the sampling? Other - explanation below Further explanation including how you ensure that the samples are taken from all the fuel burned in the month. Samples are represetative of what is being digested at the time 2.11 If the sampling analysis of the GCV or the sampling methods meet any UK, European or other standard(s) (e.g. BS, ISO, CEN), please give details. I do not know 2.12 Is any method of verification of the sampling used? no Further explanation eg what the method of verification is 2.13 Apart from GCV, what other (if any) analysis (e.g. under Environment Agency requirements) do you perform on your biomass? None, but we will analysie all digestate at the end so we make best use of it when applied on our farm

7 Procedure 1 c) Contamination 2.14 What is the origin of the fuel? For example, if the fuel is a type of wood it may be virgin wood from the forestry commission, pallets from commercial activity. The fuel to make the gas is all home grown. If in the future we are offered alternative plant material we will be eager to ensure that it is not contaminated, not only to remain within the law but to ensure that we do not damage the bactareia (gas makers) in the plant. Depletion of bacteria could result in having to close the plant empty the digestate and then start again. This is a long winded and very costly procedure Have you found any contaminants so far? If so, what were these? No 2.16 Have you identified any potential contaminants? If so, please list these? No 2.17 How do you propose to manage contamination? Please include how you will prevent contamination or how and where you will measure contamination levels, on a monthly basis, in your answer. In the short term all feedstocks will be home grown. Should we be offered suitable material from elsewhere we will need to be convinced that it is uncontaminated or we will not take it. As I said I have greater risks associated with taking contaminated material than losing my ROCs Do your measurement techniques for contamination meet any UK, European or other standard(s) (e.g. BS, ISO, CEN)? Please give details. No d) Storage 2.19 How will the biomass fuel be stored at the generating station, including any temporary storage facilities eg in a covered hanger or shed, sealed tank etc.? Please make clear whether the biomass fuel will be stored separately from other fuel sources (incl. from other biomass fuels). Slurry in a reception pit for no more than a day before going into the digester. Cow manure is generated weekly from mucking out sheds and will be stored in a concrete pad and used in the week before next mucking out the following week. Silage will be stored in a conventional clamp. cereals will be delivered to site on a weekly basis and used within a week On average, for how long will the biomass fuel stored between delivery and burning? As above

8 Procedure 1 e) off-site measurement only 2.21 Please explain the practicalities of auditing your off-site measurement facilities. n/a f) waste only 2.22 How many samples have you included in an initial set of samples from a single delivery? What is the name of the spreadsheet or other document containing this information? 2.23 How many samples have you included in an initial set of samples across deliveries? What is the name of the spreadsheet or other document containing this information? 2.24 Please explain any calculations or statistical analysis that has been done and how it shows that sampling can be representative Are you proposing a method of conservative estimation? Further explanation eg the method proposed

9 Procedure 1 g) additional information 2.26 Is there any other information that you consider to be relevant? I appreciate your desire to ensure that the RO Scheme is adhered to and no fossil fuels are used to generate electricity. What I can say that I hope will inspire confidence is that aside from being against the rules I would be very concerned that ussing fossil fuels in what is a living organism would do the process great harm and would therefore be completely against my interest to do so. continuation sheet - please include the question number that is being continued.

Further explanation eg what the method of verification is 2.13 Apart from GCV, what other (if any) analysis (e.g. under Environment Agency requirements) do you perform on your biomass?

37 Procedure 6 c) Contamination 2.14 What is the origin of the fuel? For example, if the fuel is a type of wood it may be virgin wood from the forestry commission, pallets from commercial activity Have you found any contaminants so far? If so, what were these? 2.16 Have you identified any potential contaminants? If so, please list these? 2.17 How do you propose to manage contamination? Please include how you will prevent contamination or how and where you will measure contamination levels, on a monthly basis, in your answer Do your measurement techniques for contamination meet any UK, European or other standard(s) (e.g. BS, ISO, CEN)? Please give details. d) Storage 2.19 How will the biomass fuel be stored at the generating station, including any temporary storage facilities eg in a covered hanger or shed, sealed tank etc.? Please make clear whether the biomass fuel will be stored separately from other fuel sources (incl. from other biomass fuels) On average, for how long will the biomass fuel stored between delivery and burning?

38 Procedure 6 e) off-site measurement only 2.21 Please explain the practicalities of auditing your off-site measurement facilities. f) waste only 2.22 How many samples have you included in an initial set of samples from a single delivery? What is the name of the spreadsheet or other document containing this information? 2.23 How many samples have you included in an initial set of samples across deliveries? What is the name of the spreadsheet or other document containing this information? 2.24 Please explain any calculations or statistical analysis that has been done and how it shows that sampling can be representative Are you proposing a method of conservative estimation? Further explanation eg the method proposed

40 Procedure 7 Crouchland Farm Biogas Plant Section 1: Fuels/General information 1.1 Which fuel(s) does this fuel measurement and sampling procedure relate to? What type of fuel(s) are these? 1.2 Please give details of the supplier(s) of the fuel- including name(s) and address(es). This information should be supported by evidence described in paragraph 3.3 of the fuel measurement and sampling guidance. Copies of relevant extracts from the fuel supply contracts should include details of the fuel, energy content and the duration of the contract clearly marked. 1.4 How will you make sure that your monthly ROC claim doesn't include any biomass burned which does not result in the generation of electricity? For example, if the generating station is on hot standby, being tested or there is a cancelled start it is likely that electricity has not been generated. Further explanation eg what prevents the use of biomass during start-up or how biomass is measured.

41 Procedure 7 Section 2: Fuel measurement and sampling arrangements a) Weight or volume 2.1 When is the weight or volume measurement taken?
