4 I. General Description of the Project 1. Title of the Project 5 MW Wind Energy ISO Offset Project at Villages Mada and Kotari, Tehsil Fatahgarh, District Jaisalmer, State Rajasthan, India by M/S Sangam (India) Ltd. 2. Project description, size, intentions and purpose. The proposed ISO offset project activity comprises of the installation and operation of four 1.25 MW Wind Turbine/Electric Generators (WTGs) at Villages Mada and Kotari, District Jaisalmer, State Rajasthan, India. The WTGs are connected to the grid and the generated electricity is sold to Jodhpur Vidyut Vitran Nigam Limited (Jodhpur Discom) as per the Power Purchase Agreement (PPA) for 20 years. Suzlon Energy Limited ( SEL ) is the equipment supplier and Suzlon Infrastructure Services Limited ( SISL ) is the operations and maintenance contractor for the project. The project activity assists the sustainable growth of Rajasthan state by providing clean and renewable electricity to the state electricity grid. The project falls within the small scale rating as the total generation capacity of the existing plant is 5 MW which is well below the 15MW outlined in section ID of Appendix B of the simplified modalities and procedures for small-scale CDM project activities by the UNFCCC. The project activity involves the generation of renewable power based on wind energy and its supply to the NEWNE regional grid. It hence displaces the electricity which in the absence of this project activity would have been generated from the fossil fuel powered power plants connected to the grid. Thus the project replaces the anthropogenic emissions from the fossil fuel based power plant connected to the state electricity grid. The distributed generation of the wind mills of this project activity are as follows: Capacity (MW) Village State Commissio ning date Location Meter No WTG Details 2 x 1.25 Mada 2 x 1.25 Kotari Rajasthan Sr Number 52/P, 55/P Location Sept. 30, J231, J Sr Number 231/P, 235/P Location J233, J Nos 1.25MW each Suzlon Make Current Monitoring Period for the project under ISO : (PPA signed on 23/12/2004) Year Total MWh supplied per year Emission reductions (tco2eq/yr) Total Emission reductions (tco2eq/yr) 32419

Details of the project participants and their roles. Carbonyatra Sangam (India) Ltd ISO aggregator and documentation specialist Project Owner 4. Direct and indirect emissions. Wind energy generation does not have any direct GHG emissions 5. Ownership of the project The ownership is evidenced by the invoices, contracts for Wheeling and Purchase agreements with the State Grid and third party power purchasers. The project is owned by M/S Sangam India Ltd. 6. Information regarding carbon credits generated by the project Carbon credits have not been claimed from any other standard or source. Since the credits are from wind power project, it is a renewable energy source credit. Carbonyatra has been mandated to document and trade the generated carbon offsets from this project on behalf of the project owners for the years 2004 onwards. A copy of the mandate has been provided to verifier. 7. Demonstration that the project has not created another form of environmental credit. There is currently no process or trading exchange related to the creation and/or trading of renewable energy credits or REC s in India. There are no environmental credits given to wind projects in India. The project proponent will submit an undertaking to the DOE in order to demonstrate the same.

6 II. Project Methodology 1. Title and source of methodology applied to the project. As defined under Appendix B of the simplified modalities and procedures for small-scale UNFCCC CDM project activities, the project activity falls under following project types and categories: Type: 1 Renewable Energy Projects Project Category: I.D. Grid connected renewable electricity generation Methodology AMS I.D. also refers to the approved consolidated methodology ACM0002 Consolidated baseline methodology for grid-connected electricity generation from renewable sources Scope no: 1, Sectoral Scope Energy Industries: (Renewable/non-renewable). 2. Justification for the choice of the methodology and applicability. The project is wind power project which is a renewable energy project. The project is located in India, hence the AMS I D methodology applicable for India Renewable Energy Systems has been used. Though wind energy is a clean energy, it is a costlier option, especially in India where availability of coal is in abundance. It makes coal the most preferred fuel for power generation since it is the least cost option. Wind energy on the other hand has the lowest load factor and the highest uncertainty in production because it is entirely dependent on weather conditions. Reference: The project activity meets the eligibility criteria to use the simplified modalities and procedure for small-scale CDM project activities as set out in paragraph 6 (c) of decision 17/CP.7. Details of methodology for baseline calculations for CDM projects of capacity less than 15 MW are available in the Appendix B of the simplified modalities and procedure for small scale CDM project activities. Reference has been taken from indicative simplified baseline and monitoring methodologies for selected small scale (CDM projects less than 15 MW) project activity categories. S.No Applicability Criteria Project Case 1. This category comprises renewable energy generation units, such as The project activity comprises generation of electricity using renewable energy photovoltaics, hydro, tidal/wave, based on wind power and its supply to the wind, geothermal, and renewable biomass, that supply electricity to and/or displace electricity from an electricity distribution system that is or would have been supplied by at least one fossil fuel fired generating unit. western regional grid. It hence displaces the electricity which would have other wise been generated from the power plants connected to the grid. The power plants connected to the western regional grid were predominantly fossil-fuel fired during the period of commissioning. (source: Table 3.4 of CEA General Review , , , 2. If the unit added has both renewable and non-renewable components (e.g.. a wind/diesel unit), the eligibility limit of 15MW for a small-scale CDM project activity applies only to the renewable component. If the unit added cofires fossil fuel, the capacity , ). There is neither non-renewable component added, nor co-firing required for the project activity. The renewable project capacity is 5 MW, below the limit of 15 MW.

7 of the entire unit shall not exceed the limit of 15MW. 3. In the case of project activities that involve the addition of renewable energy generation units at an existing renewable power generation facility, the added capacity of the units added by the project should be lower than 15 MW and should be physically distinct from the existing units. 4. Project activities that seek to retrofit or modify an existing facility for renewable energy generation are included in this category. To qualify as a small scale project, the total output of the modified or retrofitted unit shall not exceed the limit of 15 MW Not applicable. All the windmills are new and this project is not capacity enhancement or up gradation project Not applicable. This project is not a retrofit or modification of an existing facility. The project activity is a 5 MW Wind Power project which is less than the specified limit of 15 MW for Small scale Project activities under the applicable methodology. The project exports the power generated to the State Electricity grid and/or third party users directly. Hence the small scale methodology applicable to the project activity is Type-I Renewable Energy Projects Subset D Grid Connected renewable electricity generation is suitable.

8 2.1. Project Location Project is located in Rajasthan and is shown in the following map: District: Jaisalmer State: Rajasthan Latitude: N and N Longitude: E and E Project

9 2.2. Project Boundary The Project boundary encompasses the physical, geographical site of the renewable generation source. The proposed project activity evacuates the power to the NEWNE Region of India. The project boundary encompasses the physical, geographical sites of the windmills at Mada and Kotari sites. According to ACM0002, for the baseline emission factor, the spatial extent of the project boundary includes the project site and all power plants connected physically to the electricity system that the carbon credits project power plant is connected to. The Indian electricity system is divided into five regional grids, viz. NEWNE, Eastern, Western, Southern, and North-Eastern. Each grid covers several states. As the regional grids are interconnected, there is inter-state and inter-regional exchange. A small power exchange also takes place with neighbouring countries like Bhutan and Nepal. Power generation and supply within the regional grid is managed by Regional Load Dispatch Centre (RLDC). The Regional Power Committees (RPCs) provide a common platform for discussion and solution to the regional problems relating to the grid. Each state in a regional grid meets its demand with its own generation facilities and also with allocation from power plants owned by the Central Sector such as NTPC and NHPC etc. Specific quotas are allocated to each state from the Central Sector power plants. Depending on the demand and generation, there are electricity exports and imports between states in the regional grid. The regional grid thus represents the largest electricity grid where power plants can be dispatched without significant constraints and thus, represents the project electricity system for the Project. (Source: Table 3.4 of CEA General Review , , , , )

10 The wind energy generated from the wind farm is evacuated to the State Grid System through the State Grid s Extra High Voltage (EHV) sub-station. There are High Voltage (HV) transmission lines and complete installation of allied equipments from individual wind turbines to the facility s switchyard and from the switchyard up to the State Grid EHV sub-station, for evacuation of wind energy per JVVNL s requirements. 3. Social and environmental attributes of the project Installation and operation of the windmills does not pose any environmental hazards. The technology of harnessing wind power through windmills is environmentally safe and sound. The host Government also agrees to this fact and does not ask for any regulatory Environmental Impact Assessment report for this type of project. As a supplier of wind energy converters (wind mills), SEL. is well known in the market. 3.1 Social well being: The plant site is an isolated rural area where unemployment, poverty and other economic backwardness are prevailing; the project would lead to the development of the region. During civil works, a lot of construction work took place, which generated employment for local people around the plant site. Other than these, there are various kinds of mechanical work, which has generated employment opportunity on regular and permanent basis. Contribution towards achieving the objective of the policy on wind power generation of Government of India, which is to promote generation of energy through non-conventional sources to supplement the ever increasing demand of the state. 3.2 Environmental well being: As wind power projects produce no end products in the form of solid waste (ash etc.), they address the problem of solid waste disposal encountered by most other sources of power. Being a renewable resource, using wind energy to generate electricity contributes to resource conservation.

11 Reduction in the consumption of fossil fuels in the grid for generating additional electricity equivalent to that generated by the wind mills; CO2 abatement and reduction of greenhouse gas (GHG) emissions through development of renewable technology. The project has reduced the local air pollutants and environmental impacts due to increased share of electricity generation through wind power. As per the Schedule 1 of Ministry of Environment and Forests (Government of India) notification dated January 27, 1994, - 30 activities are required to undertake environmental impact assessment studies. The details of these activities are available at: The proposed project doesn t fall under the list of activities requiring EIA as it will not involve any negative environmental impacts, as the WEGs installed for generation of power use wind (cleanest possible source of renewable energy), thus no EIA study was conducted. 4. Without project scenario. Though wind energy is a clean energy, it is a costlier option, especially in India where availability of coal is in abundance. It makes coal the most preferred fuel for power generation since it is the least cost option. Wind energy on the other hand has the lowest load factor and the highest uncertainty in production because it is entirely dependent on weather conditions. The project activity is generating electricity from wind for which GHG emission is nil. The generated electricity is supplied to JVVNL. Thus the power generated in the project activity is actually displacing the electricity generated from the fossil fuels in the grid. In case the project activity would not have been there, the same amount of electricity would have been generated from the power plants connected to the grid of which majority are based on fossil fuels. Thus the project is replacing the anthropogenic emission from the fossil fuel based power plant connected to the state electricity grid. The project activity is in line with the Renewable Energy Policy of Government of India which targets 10% of additional grid power generation capacity to be from Renewable Energy sources by It is also getting the benefits provided by the National and sectoral policies for promoting renewable energy generation in India, (e.g. promotional measures of Electricity Act 2003).

12 5. Sources of emissions and gases included in the project. Baseline Project Activity Source Gas Included Justification/Explanation Main emission source CO 2 Yes Electricity generation from power plants Excluded for simplification. This is connected to the western CH 4 No conservative grid Excluded for simplification. This is N 2 O No conservative On-site fuel combustion due to implementation of the project activity CO 2 CH 4 N 2 O No No No Wind energy generation does not have any direct GHG emissions. 6 Baseline scenario and description of the identified baseline scenario The baseline emissions and the emission reductions from project activity are estimated based on the quantum of electricity to be exported by the project activity to the grid and the Baseline Emission Factor (BEF) of the southern regional grid calculated as a combined margin (CM), consisting of the combination of operating margin (OM) and Build margin (BM) factors and using the default weights to be used for wind projects. The project proponent wishes to calculate the Operating Margin and the Build Margin using the data provided by the Central Electricity Authority Ex-ante, and has fixed the same for the first crediting period. The Simple Operating Margin has been calculated as the generation weighted average emissions per electricity unit (tco2/mwh) for all generating sources, excluding the low operating cost and must run power plants, serving the system. The formula applied for the calculation of the Simple Operating Margin is: Where Fi,j,y is the amount of fuel i consumed by the relevant power sources j in the year y, j refers to the power sources delivering electricity to the grid excluding the low operating cost and must run power plants but including import to the grid. COEFi,j,y is the CO2 emission coefficient of fuel i (tco2/mass or volume unit of fuel), taking into account the carbon content of the fuels used by the relevant power sources j and the percent oxidation of the fuel in year y. GENj,y is the electricity delivered to the grid by source j. COEFi has been arrived using the formula: COEFi= NCVi * EFCO2i * OXIDi Where,

13 NCVi is the net calorific value (energy content) per mass or volume unit of fuel i, OXIDi is the net calorific value of the fuel as provided in 2006 Revised IPCC guidelines for default values. EFCO2i is the CO2 emission factor per unit of energy of the fuel i. The CO2 Emission Factor database (Version 5.0) of CEA has been used for arriving at the Baseline Emission Factor. As provided in the database, the Simple Operating Margin for the NEWNE Regional grid of 1.01 and a Build Margin of 0.68 has been used for the estimation of the Emission Factor. Therefore, OM= 1.01 and BM= 0.68 The default weights to be assigned are 0.75 and 0.25 for the Operating Margin and Build Margin respectively. Hence, the Baseline Emission Factor is calculated as below: EF = 0.92 t CO2/MWh Thus, the Baseline Emission Factor, calculated ex ante as 0.92 for the first crediting period will be used for the calculation of the Emission Reductions. Baseline The Central Electricity Authority (CEA) under the Ministry of Power, Government of India, has estimated the operating margin and the Build margin for the Western grid, the details of which are available on the following website. htm The data provided in Version 5.0 of the CEA database has been used for the calculation of the Build and the Operating margin. For the purpose of estimation of CERs, the Combined Margin of 0.92 will be used during the first crediting period.

14 Project Emissions The wind power project set up by the project proponent is not expected to result in any anthropogenic emissions. Therefore, Project Emissions (PE) = 0 tonnes of CO2 Leakage Sangam Industries Ltd has identified no anthropogenic greenhouse gases by sources outside the project boundary that are significant, measurable and attributable to the project activity. Hence, no leakage is considered from the project activity. Therefore, EL= 0 tonnes of CO2 GHG Emission Reduction ER = (EGy x BEF grid,y ) PE - EL Where ER- Emission reductions per annum by project activity (tones/year) EGy- Where, EGy/1000 = Net quantity of electricity supplied to the manufacturing facility by the project during the year y in KWh, and BEF grid, y = CO 2 grid emission coefficient for the electricity displaced due to the project activity during the year y (tco 2 eq/mwh). PE- Project Emissions (= 0) EL- Emission leakage (tonnes/year) (= 0) 6.

17 III. Duration of the Project 1. Starting date and ending date of the project The first WTG in this project activity was commissioned on 30 th September Hence the start date is September The expected life of the project is 20 years from the date of first WTG commissioning. 2. Operational lifecycle of the project including significant shutdown periods There have not been any significant shutdowns or down times since IV. Monitoring 1. Description of the verifier for the project. URS India has been recommended to carry out ISO verification for this project. 2. Procedures taken to ensure reliable data collection. Monitoring methodologies / guidelines mentioned in the UNFCCC document of Annex B of the simplified modalities and procedures for small scale CDM project activities for small scale projects (Type I: D) is considered as basis for monitoring methodology for the activity. The project proponent will monitor the electricity generated using energy meters. The project proponent may use electricity from the grid for start up purpose and the electricity imported will be monitored as well. Emergency Preparedness Plan The operational staff s main task is to keep a close watch on a day to day basis on the functioning of the wind turbines. In the event of adverse grid condition of grid failure, the turbine would stop functioning and would restart automatically on resumption of healthy conditions. However there may be faults which will require pre-checking the machine condition before restarting. The operating staff would also document the downtime and operating hours for each turbine along with the reasons for the downtime. The operating staff would summarize the logbook data on a monthly basis and provide the same to the head office. SEL, the O&M service provider will deploy maintenance staff at the plant to ensure minimal breakdown of the machines. Additionally, it will ensure supply of sufficient quantity of critical and essential spares and consumables for the requirement of the machines. These critical and essential spares and consumables shall be stocked at the project site to reduce the machine repair downtime. A complete set of tools and tackles will be maintained at the site at the project site by the O&M service provider and will be provided to the project site staff. The site in-charge together with the staff would ensure that periodic maintenance checks are performed on all major components like gearbox, generator, rotor blades, control panels, transformers, control panels etc. Monitoring Plan:

18 As per Monitoring para 13, Page no. 5 of referred methodology Monitoring shall consist of metering the electricity generated (EGy) by the renewable technology. (Copy this table for each data and parameter) Data / Parameter: EG y Data unit: KWh Description: Net Electricity export by the project activity is recorded (obtained from joint meter reading by JVVNL, Rajasthan Rajya Vidhyut Prasaran Nigam Ltd, SEL and project promoter) on monthly basis. (Net electricity export is equal to the total electricity export minus own consumption). According to ACM0002, the units are double checked of the measurements with receipt of sales and will be provided. c) The meter readings by the JVVNL/ Rajasthan Rajya Vidhyut Prasaran Nigam Ltd are ascertained by the Superintending Engineer RVPN, Jaipur on the basis of the joint meter readings. Meter: Number: Calibrated and testing dates: , , Accuracy and test loads were satisfactory. Source of data to be used: Value of data Description of measurement methods and procedures to be applied: QA/QC procedures to be applied: As per Schedule of CEA (notification number 502/70/CEA/DP&D, dated 17 th March, 2006) where the accuracy class of meters in generation and transmission shall not be inferior to that of 0.2S Accuracy Class the meters meet the CEA guidelines. Measured Measured Monitoring: Trivector energy meter will be used for monitoring Net Electricity Export by the project activity Data Type: measured Frequency: hourly measured Recording: Monthly from joint meter Archiving Policy: Paper & Electronic Responsibility: JVVNL and Rajasthan Rajya Vidhyut Prasaran Nigam Ltd (RRVPNL) are responsible for regular calibration of the meter annually. Calibration Frequency: Once a year. The meter is calibrated annually. The project revenue is based on the net units displaced as measured by main metering system installed at the interconnection point (substation point). Other than main meter, the project proponent has check meter so that the accuracy of main meter can be verified. The calibration of the meters will be done periodically by state electricity utility. The electronic meter that is used for monitoring is the Export-Import Energy and is, installed before the grid. The calibration procedure followed, requires calibrating the meter once every year, by RRVPNL, which is the State Electricity Utility Company which functions under Government of Rajasthan as per Central Electricity Act & it is responsible for Energy Meter calibration check with their calibrated Reference Standard Meter having tractability with International Standards through Institute for Design of Electric Measuring Instruments, Sion, Mumbai (IDEMI, Govt. of India Institution). The Purchaser/ wheeling agent of power, performs calibration check in presence of representative of owner. This meter is located at the delivery point of wind power in JVVNL grid. This accounts for the import of electricity that is used by the project

19 participant. Hence the net electricity generated is calculated from the joint meter reading and recorded /archived in paper/electronic. Other than periodic calibration of the meters, the reading of both meters will be matched every month. The net electricity exported to the grid can be cross verified with the joint meter readings also can be double checked with electricity sales receipt (Invoice). Any comment: The metering equipment (consisting of the Main Meter and the Check Meter) is identical in make and technical standards and is of 0.2% accuracy class and calibration. They comply with the requirements of the Electricity Rules. The meter readings at the Metering Point are undertaken jointly by the representatives of the State Grid/JVVNL/ Rajasthan Rajya Vidhyut Prasaran Nigam Ltd and the representative of SEL in the first week of every month. The meter readings are jointly certified by representatives of the State Grid/ JVVNL and SEL. The JVVNL/ Rajasthan Rajya Vidhyut Prasaran Nigam Ltd carries out the calibration, periodical testing, sealing and maintenance of meters in the presence of SEL representative. The frequency of meter testing is annual. All meters are tested only at the Metering Point. Data for the units supplied in is available to the verifier. Please describe briefly the operational and management structure that the project participant(s) will implement in order to monitor emission reductions and any leakage effects generated by the project activity: The project proponent has undergone an operation and maintenance agreement with the Suzlon Wind Farm Services Limited. The organizational setup implemented by them for the monitoring of generation due to the project activity along with operation and maintenance is as follows:

20 The project activity essentially involves generation of electricity from wind, the employed WEG can only convert wind energy into electrical energy and cannot use any other input fuel for electricity generation. Thus no special ways and means are required to monitor leakage from the project activity. 1. The proposed project activity requires evacuation facilities for sale to grid and the evacuation facility is essentially maintained by the state power utility (RVPNL). 2. The electricity generation measurements are required by the utility and the investors to assess electricity sales revenue and / or wheeling charges. 3. The project activity has therefore envisaged two independent measurements of generated electricity from the wind turbines. 4. The primary recording of the electricity fed to the state utility grid will be carried out jointly at the incoming feeder of the state power utility (RVPNL). Machines for sale to utility will be connected to the feeder. 5. In the event that the main metering system is not in service as a result of maintenance, repairs or testing, then the backup metering system shall be used during the period main metering system is not in service. 6. The joint measurement will be carried out on the first day of every month in presence of both parties (the developer s representative and officials of the state power utility). Both parties will sign the recorded reading. 7. The secondary monitoring, which will provide a backup (fail-safe measure) in case the primary monitoring is not carried out, would be done at the individual WEGs. Each WEG is equipped with an integrated electronic meter. These meters are connected to the Central Monitoring Station (CMS) of the entire wind farm through a wireless Radio Frequency (RF) network. The generation data of individual machine can be monitored as a real-time entity at CMS. The snapshot of generation on the last day of every calendar month will be kept as a record both in electronic as well as printed (paper) form.
