2 1 PROJECT CHARACTERISTICS Coal Mine Gas (CMM) is an unavoidable occurrence of hard coal mining. CMM mainly consists of the harmful green-house-gas methane (GWP 21). Even after the shut down of the mining activities the CMM escapes over many years through open shafts and cracks in the overburden, directly or diffusely, into the atmosphere. In this project the CMM has been sucked out of the active coal mine Haus Aden. The methane has been burned in co-generating units to the less harmful CO 2. The cogenerating units have produced power, which displaced conventional produced power and therefore saved an additional amount of CO 2. The power displacement is outside the project boundaries and is not taken into account, so that only CO 2 emission reductions resulting from the destruction of methane are calculated. The project will generate Emission Reduction Units (ERU) starting with the beginning of the first emissions-trading in the year Nevertheless all amount of emission reductions resulting from the destruction of methane since the starting date of the project down to the present day should be monitored for the purpose of the verification as Verified Emission Reductions (VER).

It is a joint venture of Steag AG, which has the entrepreneurial leadership, and Harpen AG. Carbon-TF B.V. founded in 2005 is a consultant for Mingas-Power GmbH. Carbon- TF B.V. is cooperating with the research institute Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT, which works together with Mingas-Power GmbH in the field of coal mine methane utilization since Chronological sequence: The operation of the cogeneration plant started in August The PDD has been written by Carbon-TF B.V. in December 2005 [PDD]. Validation of the project has been finished in December 2005 [TÜV-Nord-1]. A Letter of Approval for this project has been applied from the German government in January Monitoring Report Page 3 of 40

4 2 STATEMENT TO WHAT EXTENT THE PROJECT HAS BEEN IMPLEMENTED AS PLANNED The CMM utilisation plant Haus Aden consisting of six cogeneration units has been installed at the active coal mine Bergwerk Ost, section Haus Aden, Bergkamen, Germany as described in the PDD [PDD]. The plant is in operation continuously since August In September 2004 six more cogeneration units have been installed in a noise insulated hall, so that a total number of 12 units have been in operation since that date. Due to the lacking coal mine methane amount, two of these 12 units installed, have been removed in In August 2006 a third unit has been removed, so that at present nine units are running. Pictures of the plant are attached in annex 2. Monitoring Report Page 4 of 40

9 For the net-efficiency of the plant an expert appraisal by TÜV-Nord Systems has been prepared in April 2006 [TÜV-Sys-1]. Result: 37 % The calculation of emission reductions as determined in the PDD bases of an estimated efficiency with 35% (see above). This value is corrected to the value provided by the expert appraisal to 37 %. This value is conservative, because the expected net efficiency of gas engines using CMM is lower (36.6 % first stage of extension and 34.8% for the second stage of extension) see expert appraisal [TÜV- Sys-1]. Lower net efficiencies lead to more emission reductions. But to keep conservative, the emission reductions are calculated out of the sold power, using the chosen capacity of 37 % [TÜV-Sys-1]. Because in this project relatively high mass concentration of NMHC occurs, the amount of electricity generation resulting from the combustion of NMHC is subtracted from the total electricity amount. The electricity meters have been provided by RWE Westfalen-Weser-Ems Verteilnetz GmbH. This company as the owner of the meters is responsible for maintenance and calibrations. The measurements of the CMM amount and the methane concentration are provided by Deutsche Steinkohle AG (DSK). For an active coal mine these data are very important safety factors, so that the measurement equipment is regularly checked once a week. The power output and the methane amount are read out every night per remote data transmission to Steag AG, which stores the data and posts them on the Internet (the so-called Steag Energy Center Sites). The plant manager can control these data at any time by intranet access. If something goes wrong at the plant, the plant manager gets the accordant alarm message per SMS on his mobile phone.

10 Table 5-2: Uncertainties and calibrations Data Coal-minemethane amount Methane concentration Uncertainty level of data (high/medium/ low) medium medium Calibrations, calibration intervals The continuous measurement is provided by DSK, which is also responsible for calibrations. DSK has own regulations for all equipment and measurement concerning a coal mine because of safety reasons. The quality of the measurement depends on the amount of the CMM. Generally the uncertainty is low. Because the gauge is designed for relatively large amounts of CMM, the uncertainty increases with the actually occurring lower values so that the over-all uncertainty is medium. The measurement is provided by DSK, which is also responsible for calibrations. DSK has own regulations for all equipment and measurement concerning a coal mine because of safety reasons. The indication of the gas analyser is drifting, so that it has to be recalibrated ically (once a week). Methane amount low The formula requires no further controlling once it has been programmed and checked. Power output low Last calibration: 2003/2004 validity of calibration: 2011/2012 Net-efficiency low Conservative calculation with 37 % Additional electricity consumption by project German carbon emissions factor for electricity production CONS ELEC,PJ Carbon emission factor for combusted non methane hydrocarbons NMHC- Concentration in CMM, PCNMHC NMHC- Concentration relative to CH4- Concentation, r medium low low low medium expert appraisal, , [TÜV-Sys-1] one-time estimation yearly determination one-time determination one-time determination One-time determination; an average CH4-concentration has been used for the determination of r. While the NMHCconcentration in CMM is nearly constant, the CH4- Concentration is varying in a wider range. The influence of r in the further calculations is low. Every operating hours the gas engines had to be maintained with oil change e.g. through the maintenance firm HGS, which delivered the cogeneration units. Monitoring Report Page 10 of 40

12 6 DEVIATIONS FROM THE MONITORING PLAN The deviations from the monitoring plan established in the PDD are listed below: 1) The frequency of measurement as defined in P 3.1 in the PDD as permanent has been in fact recorded in a 15 minutes cycle. The 15 minutes cycle provides an optimum of significant recorded data respective a reduced amount of data which has to be stored and archived. 2) The net-efficiency has been estimated, calculated and measured once and not yearly, see external measurement report and expert appraisal by TÜV-Nord Systems GmbH, [TÜV-Sys-1]. 3) The own consumption of electricity has not been recorded electronically. An average value resulting from handwritten notes in the operation journal has been taken into account. 4) The produced electricity has not been recorded electronically. To keep conservative the sold electricity has been taken into account instead. 5) In the monitoring plan two more data are listed to be monitored: Temperature of CMM Pressure of CMM At present DSK is responsible for flow measurement and methane concentration. The measurements of temperature and pressure of CMM which are necessary for the correction of the CMM amount are included in the flow measurement gauge provided by DSK. This data are used for the internal correction within the gauge and are not available for external usage. Monitoring Report Page 12 of 40

13 7 CONSOLIDATION OF THE MONITORING PLAN WITH THE APPROVED CONSOLIDATED MONITORING METHODOLOGY ACM0008 In the following the monitoring plan established in the PDD, which has been validated by TÜV Nord, is consolidated with the Approved consolidated monitoring methodology ACM0008, which has been approved by the CDM Executive Board [ACM0008]. All additional demands which are requested in the ACM0008 are fulfilled to the extent to which they may be applicable. Monitoring Report Page 13 of 40

(1), see below The CMM suction out of the active coal mine is always in operation for safety reasons (also in absence of the project, in this case the methane would be simply blown into atmosphere). Thus the energy use for capture of the methane is outside the project boundaries. The energy use for utilisation of the CMM by the project is calculated using eq.

This mean value results from the hand-written values in the operation journal and is multiplied with the hours of operation if available. Otherwise an electricity consumption of 4% relating to the power output is used. If any -none If any -none The Carbon emission factor of the electricity industry of 2004 is CEFELEC_PJ = t/mwh This value is used as of Before 2004 the value of 2002 is used: CEFELEC_PJ = t/mwh, so the value is nearly constant.

Density of methane under normal conditions of temperature and pressure is 0.67kg/m3 (Revised 1996 IPCC Reference Manual p 1.24 and 1.16) [IPCC] - A differential pressure flow meter from the suction system of the active coal mine is used. Because the quality of the measurement result of the installed measurement depends highly on the current amount of the CMM, the uncertainty is medium (high for very low values).

Comment / Implementation by Carbon-TF relatively large amounts of CMM and the uncertainty increases highly with the actually occurring lower values. Furthermore a small amount of CMM is sent to the flare of the coal mine and therefore is not acquired. This case occurs when the total amount of CMM is larger than the amount that could be burned in the cogeneration units. In order to improve the quality of the measurement result an improved alternative method for the determination of the amount of methane send to the power plant, according with the PDD, is used. The amount of methane is calculated out of the sold electricity using P14 and P16. The uncertainty of the power measurement is extremely low while the uncertainty of the net-efficiency is medium. The resulting total uncertainty of the methane amount is smaller than those using measurement results of the Monitoring Report Page 20 of 40

33 ACM0008 (12.3) ii. Estimation of eligible CBM ID no s: B28 B38 not applicable, because no CBM is used! Monitoring Report Page 33 of 40

34 ACM Baseline emissions from power/heat generation and vehicle replaced by project ID no s: B39 B58 not applicable, because neither power/heat generation nor vehicle fuel is replaced by the project! The power generated by the project is fed into the grid and replaces of course conventionally generated power in the grid. Because the replacement of power is regulated by the German Renewable Energy Sources Act (Erneuerbare Energien Gesetz - EEG) it is not taken into account for generating additional ERU s or VER s for the project. According to the Project Mechanisms Act (Projekt-Mechanismus Gesetz ProMechG) no double marketing is allowed. Monitoring Report Page 34 of 40

35 ACM Leakage emissions from displacement of baseline thermal energy uses ID no s: L1 L4 not applicable, because no baseline thermal energy uses are displaced by the project! Monitoring Report Page 35 of 40
