8 D. Monitoring Information: The electricity supplied to the grid is metered at the 33/132 kv level at the Ajmer Vidyut Vitran Nigam Limited sub-station at Khood, Sikar. A representative of AVVNL and Enercon jointly takes the main reading and sign the meter reading on the first day of every month. Simultaneously, representatives of AVVNL and Enercon also take the joint meter reading at the back up meters at Wind farm end on Harshnath Hill. The meters are jointly inspected /tested once in a year as per the terms of the PPA. Joint inspection and testing is also carried out as and when difference in monthly meter readings exceeds the sum of maximum error as per accuracy class of main and back up meters. The latest meter testing (calibration) was conducted on 12 Oct 09. The details of the calibration are mentioned in the table 4 below: Table 4: Meter calibration detail Meter No Date of Calibration Meter No Date of Calibration Accuracy Type Make Main Meter Back-Up Meter RJB Feb-07 TNU00948 RJB Nov-08 TNU Feb-08 RJB Oct-09 RJU02180 * 12-Oct E3M021/3 Ph 4 w Secure * Old Meter was replaced with new one as LCD display was poor for older one. As mentioned in calibration report for Backup meter dated as 12 th October 2009, that old meter numbered as TNU00948 was replaced with the new meter numbered as meter number in the year of RJU The new number has been mentioned as Note: As per Guidelines for assessing compliance with the calibration frequency requirements, (EB 52 Annex 60) Section B (Cases where calibration is not conducted at the frequency specified by the methodology, monitoring plan or the CDM Executive Board guidance and/or monitoring plan) para 4 (a) states that: Applying the maximum permissible error of the instrument to the measured values, if the results of the delayed calibration do not show any errors in the measuring equipment, or if the error is smaller than the maximum permissible error;. As in the project case where the main meter is the basis for Joint meter reading has been calibrated annually. There was delay in calibration of main meter from February 2008 to November 2008 and delayed calibration did not show any errors in the measuring equipment, the error factor of accuracy class (0.2%) has been applied in a conservative manner such that the adjusted measured values resulted in lower net emissions reduction units. 8

10 Metering Equipment and Metering Arrangement Information The meter used is Trivector and the manufacturer is the Secure Meter. The meters are two-way meter and measure the electricity import and export and give the net electricity. As per the Power Purchase Agreement entered into with the electricity distribution utility, there are two meters, one main meter and one check meter. Both meters are two-way export import meters that measure both export and import of electricity and provide net electricity exported to the grid. Accordingly, we propose that the net electricity exported to grid would be the sole monitoring parameter for the project. The generation is given as: Net generation or electricity supplied = Net Export = (Export Import) Net electricity supplied to the grid is done based on apportioning method as described below. Procedure for apportioning of electricity: The apportioning of the electricity at Khood sub-station (District- Sikar, state-rajasthan) is done as per the following method at the wind farm. Total 20 nos of wind turbines (20MW) are connected to a substation through 33KV, The generation reading is collectively displayed by the Main Billing EB meter at 132 kv Khood Substation. Back up meters are also installed at all 33KV feeders for energy auditing purpose. The net generation of each of the wind turbine is then calculated considering Parameters reading of KWH Export (Generation) and KWH Import (consumption). Customer Panel Generation = Closing Customer Panel Reading Opening Customer Panel Reading Export Multiplication Factor = (Export of EB Main billing Meter Reading / Panel Reading of Entire Wind Farm i.e. here 20 WECs) Import Multiplication Factor: = (Import of EB Meter Reading / Panel Reading of Entire Wind Farm i.e. here 20 WECs) Panel Export Reading of Entire Windfarm EB main Billing Meter (JMR) EXPORT (A) EB main Billing Meter (JMR) IMPORT (B) Reading X Reading Y Reading Z 10

11 NET EXPORT (C) = (A) (B) Export Factor(EF) Import Factor (IF) Y-Z Y/X Z/X Exported Units =Export Multiplication Factor * Customer Panel Generation Imported Units =Import Multiplication Factor * Customer Panel Generation Net Export Units = Export Generation Import Generation In case the meters are found to operate outside the permissible limits, the meters are either replaced immediately or calibrated. Error correction is applied to the meter reading. Whenever a main meter goes defective, the consumption recorded by the backup meter is referred. The details of the malfunctioning along with date and time and snaps shot parameters along with load survey are retrieved from the main meter. The exact nature of the malfunctioning is determined after analysing the data retrieved and the consumption recorded by the main meter is assessed accordingly. If main as well as back up metering system becomes defective, the assessment of energy consumption for the outage period is done from the backup meters by the concerned parties as mutually agreed or at the level of Metering Committee set up under the Metering Code. The main and the backup metering systems are sealed in presence of representatives of Enercon and Ajmer Discom. Both main and backup meters are of accuracy class of 0.2 and are inspected once every year for its accuracy by AVVNL The Project is operated and managed by Enercon (India) Ltd. Enercon India limited is an ISO 9001:2000 certified Quality Management system from Germanischer Lloyd. Enercon India limited follows the documentation practices to ensure the reliability and availability of the data for all the activities as required from the identification of the site, wind resource assessment, logistics, finance, construction, commissioning and operation of the wind power project. QA/QC procedures: Uncertainty level of data is low. Data about the electricity are continuously measured by the meters, which have the accuracy class of 0.2% at the project activity site. The data are daily recorded and monthly aggregated. Electricity Sales documents for electricity delivered to grid are obtained for cross-checking purpose. 11

12 Additional Information: 1. Back-up meter was not calibrated in the year 2006 and Year 2007 but it was calibrated in year 2005 for which calibration certificate is available. When the back-up meter was calibrated in year 2008 it was working properly and error was under the permissible limit. The main meter which is the basis for joint meter reading was calibrated every year in the monitoring period. 2. As mentioned in calibration report for Backup meter dated as 12 th October 2009, that old meter numbered as TNU00948 was replaced with the new meter numbered as RJU The new number has been mentioned as meter number in the year of E.

F. Emission Reduction Calculation: The emission reduction ER y by the project activity during a given year y is the difference between baseline emissions (BE y ), project emissions (PE y ) and emissions due to leakage (L y ), as follows: ERy= BEy - PEy- Ly Project emissions: The project involves the operation of a zero-emission wind farm, so PE y = 0 There is no leakage to this project so L y = 0 Thus, ER y = BE y i.e. the emission reductions are the baseline emissions in this project. Baseline Emissions: The baseline emissions (BE y in tco 2 ) are the product of the baseline emissions factor (EFy in tco 2 /MWh) and the net electricity supplied by the project activity to the grid (EG y in MWh) BEy = EFy * EGy 13

14 Baseline emission factor (EF y ) has been calculated ex-ante and will not be updated during the crediting period of ten years. As per PDD registered, EF y = tco 2 /GWh or tco 2 /MWh Table 6: Baseline Emissions EG,Export (MWh) Vintage 01 May 2007 to 31 December January 2008 to 31 December January 2009 to 30 November EG,Import (MWh) Net Electricity supplied to Grid, EGy,Net(MWh) Total Emission factor (tco 2 /MWh) Baseline Emission (tco 2 e/year) Table 7: Emission Reductions Vintage Baseline Emissions (tco 2 e/year) Project Emissions (tco 2 e/year) Leakage (tco 2 e/year) Emissions Reduction (tco 2 e/year) 01 May 2007 to 31 December January 2008 to 31 December January 2009 to 30 November Total emissions reduction (ERy) for the monitoring period Table 8: VER comparison Vintage VERs as per registered PD VERs as per actuals May-07 to Dec Jan-08 to Dec Jan-09 to Nov Total The plant load factor (PLF) based on actual generation under monitoring period was found as %. The PLF value taken in PD is 20%. The actual PLF observed in monitoring period is 14.8% higher than the PLF value taken in registered PD. 14

15 Plant Load Factor for wind power projects is driven by the wind density and wind speed which in turn are influenced by changes in the wind stress associated with seasonal variations in weather. Wind patterns for any wind farm site vary from year to year and consequently the ensuing electricity generation also varies. Any variation in PLF is beyond the control of project proponent and could not have been envisaged beforehand. G. Roles and Responsibility: The Project is operated and managed by Enercon (India) Ltd.
