4 1. General Description of the Project: 1.1 Title of the Project 5 MW Wind Energy Project at Villages Mada and Kotari, Tehsil Fatahgarh, District Jaisalmer, State Rajasthan, India by M/S Sangam (India) Ltd Project description, size, intentions and purpose. The proposed project activity comprises of the installation, and operation of four number of 1.25 MW Wind Turbine/Electric Generators (WTGs) at Villages Mada and Kotari, District Jaisalmer, State Rajasthan, India. Suzlon Energy Limited ( SEL: ) is the equipment supplier and Suzlon Infrastructure Services Limited ( SISL ), a subsidiary of Suzlon Energy Limited is the operations and maintenance contractor for the project. 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. The project activity involves the generation of power based on renewable wind energy and its supplied to the NEWNE regional grid. It hence displaces equivalent quantum of electricity which would have come from grid. In India grid power is predominantly fossil fuel based (source: ) hence equivalent grid power would have resulted in CO 2 emission thus resulted in net addition in anthropogenic emission. The distributed generation of the windmills of this project activity is as follows: Capacity (MW) Village 2 x 1.25 Mada 2 x 1.25 Kotari State Commissioning date Rajasthan Sept. 30, 2004 Location Meter No WTG Details Sr Number 52/P, 55/P Location J231, J232 Sr Number 231/P, 235/P Location J233, J Nos 1.25MW each Suzlon Make model S66. 4

7 3. Details of the project participants and their roles. Carbon Yatra and Maverick Incorporation were authorized entities involved in Project document preparation. Sangam (India) Ltd is the project owner. 4. Direct and indirect emissions. The project activity involves utilization of renewable wind and no secondary fuel is consumed therefore there is no direct emission from project activity. During installation of wind mill there has been some emission associated with transportation however this is one time and amounts insignificant amount of emission hence can be neglected. During start of WTG to overcome static friction some amount of power is required which is imported. This has been taken care as emission reduction is claimed only on net power exported to grid. 5. Ownership of the project The project activity has invoice in name of project proponent; there is wheeling and purchase agreement with State Grid (statutory body) and third party power purchase. 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 under any other GHG scheme/ program.

Present documents intends to declare the same on behalf of project proponent. 7

8 8. Project Methodology 8.1. Title and source of methodology applied to the project. Type: 1 Renewable Energy Projects Project Category: I.D. Grid connected renewable electricity generation Methodology AMS I.D as specified by UNFCCC CDM approved small scale methodologies Justification for the choice of the methodology and applicability. The wind power project, of this size meets the applicability criteria of methodology and the methodology has been used as authentic publicly available reference document. As methodology mandates the size of project should not be greater than 15 MW and project activity with total installed capacity of 5 MW is well within it. Applicability Criteria Project Case Criteria: This category comprises renewable energy generation units, such as photovoltaics, hydro, tidal/wave, 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. Project fulfillment of criteria: The project activity comprises generation of electricity using renewable energy based on wind power and its supply to the 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 regional grid are predominantly fossil-fuel fired (source: ) Criteria: 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. Project fulfillment of criteria: 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. Criteria: 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. Project fulfillment of criteria: Not applicable. All the windmills are new and this project is not capacity enhancement or up gradation project 8

9 Criteria: 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. Project fulfillment of criteria: 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. 8.3 Baseline and emission reduction: Since project activity generates and exports renewable power to grid, in absence of this renewable source which would have come from combination of fossil and non fossil fuel. The project activity is renewable electricity generation for grid system, which is predominantly fossil fuel based. As per simplified baseline and monitoring methodology WH unit produced by renewable source and multiplied by emission coefficient is calculated in transparent manner. As per referenced methodology, in present project activity average of appropriate operating margin and built margin has been considered for the purpose of baseline calculations. Where: (i) The approximate operating margin is the weighted average emissions of all generating sources serving the system, excluding hydro, geothermal, wind, low-cost biomass, nuclear and solar generation. (ii) The build margin is the weighted average emissions (in kg CO2equ/kWh) of recent capacity additions to the system, which capacity additions are defined as the greater of most recent 20% of existing plants or the 5 most recent plants. The Central Electricity Authority (CEA) under the Ministry of Power, Government of India, has estimated the operating margin and the Build margin for the grid, the details of which are available on the following website. 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 Emission As 9

10 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: Emission Factor = 0.92 t CO2/MWh Thus, the Baseline Emission Factor, calculated ex ante as 0.92 for the present project activity. Emission factor use in present project activity: 0.92 tone of CO 2 /MWh. 8.4 Power generated and emission reduction: PPA signed on 23/12/ Total MWh supplied per year Calculated Emission reductions (tco2eq/yr) Emission reductions (tco2eq/yr) Total Emission reductions (tco2eq/yr) Barriers: There has been inconsistency in statutory/regulatory bodies approach towards utilization of renewable source of energies. This inconsistency was pertaining to sales of power from wind installation the added to further risk for investor. The inconsistency is evident as detailed below: March 1999 February 2000: Purchase of electricity at Rs 2.75 (US$ 0.061/kWh) with just 2% wheeling charges along with sales tax incentives. The developer was allowed to bank electricity for one year. February 2000 April 2003: Purchase of electricity at Rs 3.03 (US$ 0.067/kWh) while the wheeling charges were kept same at 2%. The provision for banking for 12 months has been limited to end of financial year only (March 31). If the banking period is exhausted and the electricity was not sold out by then, the state power utility will buy balance amount of electricity at 60% of the agreed purchase price. 10

11 April 2003 October 2004: Purchase of electricity at Rs 3.32 (US$ /kwh). The wheeling charges have been drastically increased from 2% to 10% for the volume of electricity supplied to the grid. The banking period has been reduced from 12 months to the end of calendar year (December 31). October 2004 Onwards: The present policy regime in the state of Rajasthan is not conducive for business investment in WEG as the purchase price has been reduced from Rs 3.32 / kwh (US$ /kwh) to Rs 2.91 / kwh (US$ / kwh) which is 13% lower then the previous power policy. Indian electricity sector is gearing up for the Availability Based Tariff (ABT) in which the generators with firm delivery of power against commitment will start getting more price for the generated power, whereas investor in WEG will have to bear this setback as the generator cannot play in the market for committed supply of electricity and will be left out for lower rates. Such a non-conducive environment is prohibiting investment in RE sector for power generation. The availability of additional revenue stream from sale of carbon offsets was therefore considered as a medium for mitigating the policy risks associated with the project activity. 11

12 10. Project Location Project is located in Rajasthan and is shown in the following map: Project 12

13 District: Jaisalmer State: Rajasthan Latitude: N and N Longitude: E and E 11. 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. 12. 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 established and leading player in Indian market. The project meets the criteria as stipulated by host country, justified above, for social and environmental well being. 13. 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. 13

14 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 Source: Relevant data in the project Data / Parameter: EGy Data unit: MWh Description: Net electricity Generated and fed into the grid less electricity imported. Source of data used: Joint Meter reading Justification of the choice of data or description of measurement methods and procedures applied: Net electricity generated and fed to the grid is used in calculation of emission eductions. The meters installed can record both the export of electricity to the grid and the import of electricity. Additional Information: Electricity generated and fed to the grid is sold to the grid partially and used for captive consumption. The set off is available through the regular monthly electricity bills raised by the grid for the power consumption at the plants. 15. Duration of the Project and crediting period Starting date and ending date of the project The first WTG in this project activity was commissioned on 30th September Hence the start date is September The expected life of the project is 20 years from the date of first WTG commissioning Operational lifecycle of the project including significant shutdown periods There have not been any significant shutdowns or down times since the machine was commissioned on September

15 16. Monitoring 16.1 Monitoring Plan: As per Monitoring para 13, Page no. 5 of referred methodology Monitoring shall consist of metering the electricity generated (EGy) by the renewable technology Data / Parameter: EGy 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). 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. As per Schedule of CEA (notification number 502/70/CEA/DP&D, dated 17th 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. Source of data to be used: Measured Monitoring: Trivector energy meter will be used for monitoring Net Electricity Export by the project activity 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. QA/QC procedures to be applied: 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 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 15

16 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). 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 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. 16
