3 1. Description of Project 1.1 Project Activity The large scale bundled project activity involves implementation and operation of 20 Wind Electric Generators (WEGs) of individual capacities 1.25 MW at Dhule, Sangli and Nandurbar in Maharashtra totaling an installed capacity of 25 MW. The monitoring report pertains to the period from 1 April 2006 to 31 October The project activity harnesses wind energy to generate and supply electricity to the NEWNE electricity grid of India. The Project displaces fossil fuel based electricity generation that would have otherwise been provided by the operation and expansion of the fossil fuel based power plants in the NEWNE electricity grid, thereby leading to reduction in emission of greenhouse gases associated with fossil fuel based electricity generation. The project is also under CDM validation. Draft Validation Report of the project has been issued and currently the CRs and CARs are being closed. Contribution of the project activity to sustainable development: Social well being The proposed project activity leads to alleviation of poverty by establishing direct and indirect employment benefits accruing out of ancillary units for manufacturing lattice towers for erecting the WEGs and for maintenance during operation of the project activity. The infrastructure in and around the project area will also improve due to project activities. This includes development of road network and improvement of electricity quality, frequency and availability as the electricity is fed into a deficit grid. Economic well being The project activity leads to an investment of about INR million to a developing region which otherwise would not have happened in the absence of project activity. The generated electricity is fed into the NEWNE Grid through the local grid, thereby improving the grid frequency and availability of electricity to the local consumers (villagers & sub-urban habitants) which will provide new opportunities for industries and economic activities to be setup in the area thereby resulting in greater local employment, ultimately leading to overall development. The project activity also leads to diversification of the national energy supply, which is dominated by conventional fuel based generating units. Environmental well being The project utilizes wind energy for generating electricity which otherwise would have been generated through alternate fuels (most likely - fossil fuel) based power plants, contributing to reduction in specific emissions (emissions of pollutant/unit of energy generated) including GHG emissions. As wind power projects produce no end products in the form of solid waste (ash etc.), they address the problem of solid

4 waste disposal encountered by most other sources of power. Being a renewable resource, using wind energy to generate electricity contributes to resource conservation. Thus the project causes no negative impact on the surrounding environment contributing to environmental well-being. Technological well being The project activity leads to the promotion of 1.25 MW Wind Electric Generators (WEGs) into the region, demonstrating the success of large sized wind turbines, which feed the generated power into the nearest sub-station, thus increasing energy availability and improving quality of power under the service area of the substation. Hence the project leads to technological well being. 1.2 Project Participant Name of Party involved ((host) indicates a host Party) Private and/or public entity(ies) project participants (*) (as applicable) Kindly indicate if the Party involved wishes to be considered as project participant (Yes/No) Government of India (Host) Resurge Energy Private Limited No 1.3 Technical Description Project Location The project is spread over three districts namely Dhule, Sangli and Nandurbar in the state of Maharashtra.

Baseline Methodology Title of Methodology: ACM0002 Consolidated Methodology for grid connected electricity generation from renewable sources Version: 09 Sectoral Scope: Monitoring Methodology and Plan 3.1 Monitoring Methodology The monitoring methodology is used in conjunction with approved baseline methodology ACM0002 ( Consolidated methodology for grid connected electricity generation from renewable sources ). 3.2 Parameters Monitored The monitored parameters as per the registered PD are- Parameter Description EG y Electricity supplied to the grid (calculated) EG y = EG JMR, p, export - EG JMR, P, import n 0 m 0 EG n EG m, y, y EG JMR,export EG JMR,import Total Electricity Generated from all wind turbines of the project for each site Dhule, Sangli and Nandurbar The total electricity generated from all other wind turbines attached to the common Substation meter at the substation at each site (Dhule, Sangli and Nandurbar) Electricity supplied to the grid from all wind turbines at each site (including project activity in Dhule, Sangli and Nandurbar) attached to the common Substation meter at the substation and metered jointly by SISL representative and MSEDCL. Electricity drawn from the grid by wind farm for all wind turbines at each project site (including project activity) attached to the common MSETCL meter

10 at the substation and metered jointly by SISL representative and MSEDCL. EG JMR,p,export EG JMR,p,import Electricity supplied to the grid from the project activity at each project site (Dhule/Sangli/ Nandurbar) Electricity drawn from the grid from the project activity at each installation site (Dhule/Sangli/ Nandurbar). As there are 3 installation sites, the calculations have to be for each site. The monitoring parameters as per the applied deviation are- Parameter EG y Description Electricity supplied to the grid (calculated) EG y = EG JMR, p, export - EG JMR, P, import As there are 3 installation sites, the net electricity exported to the grid will be calculated for each site based on the MSEDCL credit reports. EG JMR,p,export EG JMR,p,import Electricity supplied to the grid from the project activity at each project site (Dhule/Sangli/ Nandurbar). As there are 3 installation sites, the export for each site will be sourced from the MSEDCL credit reports. Electricity drawn from the grid from the project activity at each installation site (Dhule/Sangli/ Nandurbar). As there are 3 installation sites, the import for each site will be sourced from the MSEDCL credit reports. Justification for applied deviation in monitoring plan- The monitoring procedure followed is as per the regulations of the local discom, MSEDCL. Clause [b] states that The Joint Meter Reading will be furnished to the office of superintending Engineer, O&M Circle, Dhulia for further processing. The total units received for sale of Wind energy to MSEDCL will be ascertained by S.E (O&M) Circle, Dhule on the basis of joint meter reading.

11 Clause [c] states Wherever more than one Power Producer(s) are delivering energy produced by them using the common evacuation system and through common metering equipment, then they shall identify a common agency responsible for joint meter reading with MSEDCL. The joint meter reading taken at common evacuation system shall be supported by meter readings of individual power producers using such common evacuation system. Based on this break up, limited to total energy delivered, the power generated from the individual power plant shall be certified by MSEDCL. It is clear from the above clauses the scope of apportioning rests entirely with MSEDCL and the identified common agency. The identified common agency in this case is Suzlon Infrastructure Services Limited (SISL). SISL has access to the controller meter reading of all the WEGs in the wind farm and supplies the same to MSEDCL for apportioning. MSEDCL apportions the energy based on controller reading supplied by SISL and the energy delivered at MSEDCL Grid sub-station meter on a monthly basis. n m EG n, y EG m, y Thus the parameters 0, 0, EG JMR,export, and EG JMR,import are not available for the PPs to carry out apportioning. The identified monitoring parameters in the applied deviation would thus be only- EGy, EG JMR, p, export and EG JMR, p,import We would thus like to seek a deviation in the monitoring plan. The monitoring parameters would only be EG y,eg JMR, p,import. and EG JMR,p,export as mentioned in the energy delivered report issued by MSEDCL. The apportioning by MSEDCL is authentic as it uses these values to make payment to the PPs. EGy is the difference of. EG JMR,p,export and EG JMR,p,import The proposed deviations in monitoring plan are in line with the registered PD and the guidelines of the Voluntary Carbon Standard , The four deviations in the monitoring plan are listed below 1. Now net electricity exported to the grid, EG y, is being directly taken from the energy delivered report issued by MSEDCL, which it issues after apportioning based on WEG controller readings provided by SISL and energy recorded at the sub-station. The calculated ER are based on the net electricity supplied which remains same in both the cases i.e. registered PD and revised monitoring plan mentioned in the version 03 of the monitoring report. Thus the ER calculated through this revised procedure has no effect on ER calculations mentioned in the registered PD. 2. The accuracy class of meters mentioned in the registered PD is 0.5%. The PPA also stipulates this accuracy class. However, the meters installed by MSEDCL are of more accuracy class of 0.2%. We also like to seek a deviation in the accuracy class of the meters. 3. The calibration frequency mentioned in the validated PD is not followed strictly. So the PP has applied maximum permissible error of 0.2% to export and import to calculate the net electricity supplied by the WEGs for emission reduction calculation for delay calibration. 4. Some of the WEGs belong to this bundled project activity have undergone change in feeder line due to expansion of wind sites in Maharashtra.

The monitoring parameter, EG JMR,p,export, EG JMR,p,import Net electricity supplied to the grid for each of the Projects is obtained from the energy delivered at MSEDCL reports / tariff invoices raised on MSEDCL (Maharashtra State Electricity Distribution Corporation Limited). Grid emission factor - The emission factor, tco 2 /MWh, for the NEWNE Grid has been calculated ex ante and does not require monitoring. Details of Baseline data: Data of Operating and Build Margin for the three financial years from to has been obtained from - The CO 2 Baseline Database for the Indian Power Sector Ministry of Power: Central Electricity Authority (CEA) Version 4 Dated: October 2008 Key baseline information is reproduced in annexure Monitoring Plan The applied methodology, ACM0002, requires monitoring of the electricity supplied to the grid. The Project proponent has signed an Operation and Maintenance contract with the supplier, Suzlon Infrastructure Service Ltd. to operate the wind mills for a period of ten years from the date of commissioning of each Wind Energy Converter. The performance of the mills, safety in operation and scheduled/breakdown maintenances are organized and monitored by SISL. SISL would monitor the generation of the WEC daily on a regular basis and will maintain a log book recording daily generation details for each WEC comprising the project, as metered at the wind farm. SISL will also provide daily data generation through /website.

14 MSEDCL carries out the calibration, periodical testing, sealing and maintenance of meters in the presence of SISL representative. The frequency of meter testing is annual. All meters are tested only at the Metering Point. The WEGs are installed at 3 different (Dhule, Sangli and Nandurbar) locations in Maharashtra. Each location follows the same procedure for metering. The write-up below is for one of the locations. The layout of the WEGs at each location is as follows The generated electricity is measured through a two step procedure wherein the first metering is carried out at the controller of the machine with on-board meter and the second metering point being at the substation.

15 Apportioning method- Suppose a wind farm have 50 WEGs connected at the substation. The gross generation of all 50 WEGs is G G = 50 0 EG n, y (Adding all controllers) G G =G 1 +G 2 +G 3 + G 50 (Controller reading) (G 1 = EG m,y ) The values for WEG G 1, G 2, G 3... G 50 can be measured at respective WEG controller reading. The total gross export (G export = EG JMR,export ) of electricity in to grid will be measured at substation. G export = G 1 export +G 2 export +G 3 export +. G 50 export The value of (G export = EG JMR,export ) can be available from Joint meter reading (Main meter) reported as per procedure mentioned in section of PPA (Joint Meter Reading). Total gross import (G import = EG JMR,import ) of electricity from grid will be measured at substation meter for all WEGs connected. G import = G 1 import +G 2 import +G 3 import +. G 50 import The WEG wise electricity generation (G 1 export ) & electricity import (G 1 import ) breakup can be derived as follows- (G 1export ) = (G export * G 1 ) / G G (G 1import ) = (G import * G 1 ) / G G Hence, the WEG wise net electricity generation (G 1 net export )/ units for credit can be derived as follows- (G 1 net export ) = G 1export - G 1import

16 Similarly, G 2 net export, G 3 net export, G 50 net export EG JMR,p,export = 50 0 G 1,exp ort EG JMR,p,import = 50 0 G 1, import This net electricity generation/units for credit (G 1 net export ) value is the basis for the net electricity supplied to grid & the same is considered for emission reduction calculation. Once the net electricity generation/units for credit is calculated the MSEDCL issues a monthly net generation report/ monthly credit note towards the individual WEG PP. Then PP will raise invoice against state electricity utility for selling of power. EG y, the net electricity supplied to the grid by the project activity, is calculated as follows: EG y = EG JMR, p, export - EG JMR, P, import The same meter is used for the calculation of import and export of energy as they don t take place simultaneously. The general conditions set out for metering, recording, meter readings, meter inspections, test & checking and communication are as per the PPA (Power Purchase Agreement) with MSEDCL. Metering: The delivered energy is metered by MSEDCL and SISL at the low voltage side of the step up transformer installed at the sub-station. Metering Equipment: The accuracy class of meters mentioned in the registered PD is 0.5%. The PPA also stipulates this accuracy class. The installation of meters is under the purview of MSEDCL however, the meters installed by MSEDCL are of more accuracy class of 0.2% and in terms of quality of measurement these set of meters are more accurate than 0.5% accuracy class..the metering equipment is maintained in accordance with electricity standards. The meter has the capability of recording hourly and monthly readings.

17 Meter Readings: The monthly meter reading will be taken jointly by the MSEDCL and SISL every month for the preceding month. At the conclusion of each meter reading an appointed representative of the MSEDCL and SISL sign a document indicating the number of kwh indicated by the meter. The net energy sent out by each project owner shall be taken from the credit note published by MSEDCL. The credit note details the energy supplied to grid, energy intake from the grid and the net energy supplied to the grid for each project owner. Inspection of Energy Meters: The main and check meters (export and import) and all associated instruments such as CT/PT installed at the project site shall be of 0.2 % accuracy class. Each meter is jointly inspected and sealed on behalf of MSEDCL and SISL. Meter Test Checking: The meter is tested for accuracy annually with reference to a portable standard meter. The portable standard meter is owned by the MSEDCL and tested and certified from an accepted laboratory standard meter in accordance with electricity standards. The meters are deemed to be working satisfactorily if the errors are within specifications i.e. ± 0.2 %. The consumption registered by the meter will hold good for the purpose of billing as long as the error in the main meter is within the permissible limits. If during the tests, the meter is found to be beyond the permissible limits of error, the meter shall be immediately calibrated and the correction applied to the reading registered by the meter to arrive at the correct reading of energy supplied for billing purposes for the period from the last month s meter reading up to the current test. Billing for the period thereafter till the next monthly reading shall be as per the calibrated meter. 4. GHG Emission Reductions 4.1 Emission reductions are calculated as: ERy = BEy PEy LEy Where: BEy PEy LEy is the baseline emissions is project activity emissions and; is the amount of emissions leakage resulting from the project activity. Baseline Emissions for the amount of electricity supplied by project activity, BEy is calculated as BEy = EGy * EFy Where: EGy EFy is the electricity supplied to the grid, is CO2 emission factor of the grid (calculated ex ante).

18 Since project emissions (PEy) and leakage (LEy) from the wind farm activity are nil, emission reductions is equal to baseline emissions. The emission reduction of connected WEGs for period for which the calibration was not done yearly in Dhule and Sangli have been modified according to Annex 60, EB 52. The guidance from EB clarifies that in case the calibration is not carried out according to the monitoring plan, the maximum of the errors; maximum permissible error and error identified in the recent meter testing, should be applied. As the most recent meter testing doesn t indicate any error beyond permissible error, we have applied the maximum permissible error of the meters (0.2%). We have deducted the export by 0.2% and increased the import by 0.2%. The following table summaries the dates of calibration and the period for which the guidance was followed in the ER calculations.

Annual testing of meter has not been carried out as the testing is under the purview of MSEDCL and the PPs have no say in this regard. Example to demonstrate the correction as per Annex 60, EB 52. WTG No. G342 (Balar Exports) for the month of April Export (as indicated in the credit note issued by MSEDCL) = kwh Import (as indicted in the credit note issued by MSEDCL) = 20.6 kwh Correction in Export = ( %x ) = kwh Correction in Import = ( %x20.6) = kwh Corrected Net Export to the grid (EGy for April 2006)= ( ) kwh = kwh

20 Accordingly, emission reductions are calculated as: Monitoring Period Net Electricity supplied to grid 1 Baseline Emission Factor Annual Emission Reductions (MWh) (tco 2 e/mwh) (tco 2 e) April 06 to December 06 33, , January 07 to December 07 30, , January 08 to October 08 31, , Total Emission Reductions = 86,436 tco 2 e Please refer to the attached excel sheet for details of the calculations 4.2 Comparison with estimated emission reductions In the VCS PD the estimated net annual generation from the project activity was 43.8GWh. The electricity generation from annual monitoring of project activity averages GWh. This translates into emission reductions of 86,436 tco 2 e over the given monitoring period. The difference in estimated and actual emission reductions is attributable to the PLF achieved by the project during its running vis-àvis the PLF considered during start date of project. While the latter was taken at 20% (from the MERC order relevant at project start date), the actual PLF obtained over the monitoring period from 1 April 2006 to 31 October 2008 is around %. Thus, the obtained VER from the project are on the down side. Total Generation(MWh) 95, Total no of years 2.58 Average generation(mwh) 36, Average PLF(%) Electricity supplied to the grid over the VCS monitoring period is furnished in annexure 2.

21 5. Environmental Impact As per the Schedule 1 of the EIA notification dated 14th September 2006, given by the Ministry of Environment and Forests (Government of India) under the Environment (Protection) Act 1986, EIA is not a regulatory requirement in India for wind energy projects. Thus the project activity doesn t fall under the list of activities requiring EIA. The project activity will not involve any negative environmental impacts, as the WEGs are installed for generation of power using wind which is a clean source of energy.
