FC Tonnes Total consumption of fossil fuel in ear B.2.4. Data concerning leakage: No leakage occurred. As this project activit uses biomass it is to follow the General guidance on leakage in biomass project activities (Version 02) of the UNFCCC. Fulfilling the requirements of the guidance it is shown that the project activit uses a surplus of the biomass. The amount of available biomass in the region is at least 25% larger than the biomass used in the project activit. Please find below the determination of the amount of available biomass in the region as well as the biomass used b the project activit. As juli flora has not been used during this monitoring period the amount available of this biomass is not reviewed. For the determination of the total amount of available mustard crop residues in the region official data of the "District Statistical Data Book" published b Economical & Statistical Directorate, Government of Rajasthan, Jaipur for the ear has been used. The amount available for the related period is 265,756 t of mustard crop residues. Based on a third part stud performed at the time of the procurement of the mustard crop residues for this monitoring period in 2008, as the onl competing users of the biomass, brick kilns were found as also explained in the PDD. According to this stud 4 41,300 t of mustard crop residues are used b brick kilns in the region (50 km radius around the Tonk plant). For conservativeness reasons we are using for the Tonk plant the amount of biomass procured for the period from until which is 135, tons or 52.68% of the available mustard crop residues in the region. Summing up the two users of the mustard crop residues, the total amount of used biomass is 176, tons, which is equal to 68.78%, leaving 31.32% of mustard crop residues available for other purposes. Leakage can be ruled out. B.3. Data processing and archiving: Data handling was carried out according to the description in the PDD. Furthermore documentation showing procedures for data handling and archiving were available to the DOE on-site. B.4.

10 Project 1774: Electricit generation from mustard crop residues: Tonk, India page 10 D.2. GHG emission reductions (referring to B.2. of this document): D.2.1. Project emissions: No project emissions occurred during this monitoring period. The complete electricit generation was based on renewable biomass input and no fossil fuel was used. Based on the current equipment of the plant the use of a fuel different from biomass is not possible. For the use of coal as the onl fossil fuel to be realisticall fired together with biomass, expensive and extensive modifications are necessar. These modifications are not implemented and are also not planned for the future. Following this, the parameter FC equals zero. The net exported electricit alread includes the emissions from imported electricit which are deducted from the gross exported electricit. D.2.2. Baseline emissions: The baseline emissions consist of the net amount of electricit produced solel b biomass and exported to the grid multiplied with the ex-ante defined emission factor for the respective grid. As defined in the PDD the exported and imported electricit are monitored and used for the emission reduction calculation. The imported electricit is discounted from the exported electricit and results in the actual exported amount of electricit. For the case fossil fuel is used, according to the baseline methodolog AMS-I.D version 11, the amount of electricit generated using exclusivel biomass fuels needs to be compared with the amount of electricit generated calculated using specific fuel consumption and the amount of each tpe of biomass fuel used. The lower of the two values will be used to calculate ex-post emission reductions. As no fossil fuel was used during this monitoring period, formula 1 of the table under D.1. in this document is applicable: TEG projectpla nt, EGt, The above was considered in the following table showing the baseline emissions of the project activit calculated as per the PDD: Month E t, (corresponds to electricit exported) [MWh] E pl, (corresponds to electricit imported) [MWh] E t, - E pl, [MWh] Baseline emissions [tco 2 ] Oct Nov Dec Jan Feb The baseline emission factor of the grid (ex-ante) used for the calculations above, as per the PDD, is tco 2 /MWh.

11 Project 1774: Electricit generation from mustard crop residues: Tonk, India page 11 D Biomass consumption: Biomass tpe SFC: specific fuel consumption [t/gwh] BC : total consumption of dr biomass[t] Direct biomass input boiler [t] theoretical electricit production (based on direct boiler input) [GWh] actual electricit production [GWh] CEG: conservative electricit generation; MIN (theoretical, actual) [GWh] Mustard crop residues Wood chips Juli Flora , , SUM 18, , The applicable methodolog AMS-I.D version 11 and the registered PDD of the project activit require the monitoring of the biomass input to the boiler on a earl basis. This first monitoring period is covering a period of less than a ear and furthermore a period outside the main procurement period (March to June) of the biomass. Therefore in order to be transparent we are reporting more than the biomass related monitoring parameter of the PDD, BC,i. This parameter is delivering the total consumed biomass in one ear period per biomass. The values are determined via the weighbridge at the entrance of the plant where each deliver is registered. Meaning the weighbridge is determining the amount of biomass that is delivered to the plant and will be used. As each biomass that is delivered and stored at the plant will also be used this is equal to the biomass input to the plant. However as the main procurement of the biomass is happening during the harvesting season of the mustard from March to June, there arises a discrepanc when looking at the values of the biomass procurement and cross checking based on these against the theoretical electricit production. As onl a few biomass is procured and electricit is produced based on the biomass that is alread stored for months, the comparison would be negative for the project. This is the case during this monitoring period. In order to solve this discrepanc, we are also reporting the values of the direct biomass input to the boiler as these are also comprising the biomass sourced from the storage area. A belt conveor is installed at the feeding sstem of the boiler and this is used for compan internal purposes. For this monitoring period this data is made available in order to show the direct biomass input to the boiler. The related data can be followed in the table above and in the related Excel sheet. Please note that the weighbridge is still seen as the onl appropriate and accurate monitoring device, taking also in account each tpe of biomass, however for cross checking purposes we think that the additional reporting of data from the belt conveor is reasonable. D.2.3. Leakage: Leakage is considered to be zero (see also section B.2.4). D.2.4. Summar of the emissions reductions during the monitoring period: According to the general equation ER = BE (PE + L )

12 Project 1774: Electricit generation from mustard crop residues: Tonk, India page 12 Emission reduction = Baseline emissions total ( ) It can be followed that the emission reductions of the project activit is equal to the baseline emissions. The emission reductions for the period which is covered b this monitoring report is therefore 19,232 t CO 2e. Currentl the ex-post monthl average emission reduction exceeds the ex-ante monthl average estimate. This is based on several facts: 1. The main reason for exceeding the ex-ante estimate is the plant load factor (PLF). For the PDD it was assumed that the PLF would not exceed 65%. This was based on experience provided from the other biomass plant operated b KPTL named Ganganagar (registered as CDM project no. 0058). Evidence for this conservative PLF was provided in the PDD and the accompanied documentation. This PLF was seen as appropriate due to the fact that the implementation of the biomass plant Ganganagar faced a number of technical barriers that led to several months of shutdown and therefore a low PLF. As the Tonk plant is comparable to the one at Ganganagar the same assumptions were taken. This is evidenced b the fact that the Tonk plant was heavil influence b technological problems in the ear A fire burned down the whole biomass storage area surrounding the plant and caused severe damage to the plant installations itself. This resulted in a shutdown of the plant of 5 months. Even in case the plant would have run the remaining 7 months of the ear 2007, it would have reached a PLF of 58% maximum. Therefore the PDD estimate of 65% PLF is seen as appropriate based on the knowledge of the time the PDD was written. 2. The ex-ante estimate is incorporating drought periods and bad harvests. Therefore a low PLF is estimated for two ears of the first 7 ear crediting period in order to take into account the lower suppl of mustard crop residues. 3. The quantit and qualit of the procured biomass was ver good and exceeded the expectations. 4. The performance of the equipment is excellent and no major breakdowns occurred during the monitoring period. It is to note that currentl the overall estimate for one ear is not exceeded, however given the excellent performance of the equipment and the good suppl of biomass it is likel that the project might exceed the overall estimate for one ear which is 31,614 tco 2 e for a ear without drought period. Please note that the additionalit of the project activit is not influenced b the higher ield of emission reductions achieved as the barrier faced b the project activit is the technological barrier for which a number of evidences (e.g. the fire incident in 2007) were alread submitted to the UNFCCC. A final conclusion can be made after the finalisation of one full ear of monitoring. This will be done during the next periodic verification.
