In sales receipts, incomes not deriving from electricity production but declared as electricity supplied to grid because of limitations of accounting system shall be identified and subtracted. If differences still occur, the more conservative amount shall be used. Only the net electricity export to the grid shall be taken into account. This means that the monitoring measurement method shall exclude electricity imported from the grid by the project activity and possible transmission losses. 10

11 3.3 Description of the Monitoring Plan The objective of the monitoring plan is to ensure the complete, consistent, clear, and accurate monitoring and calculation of the emissions reductions during the whole crediting period. The project owner is mainly responsible for the implementation of the monitoring plan, and the Grid Company will cooperate with the project owner. 1. Monitoring Objective The only parameter to be monitored is the amount of electricity supplied to the grid since the baseline emission factor is fixed by ex-ante calculations. 2. Monitoring Organization A chief monitoring officer will be appointed by the project owner, who supervises and verifies metering and recording, collects data (meter s data reading, sales/ billing receipts), calculates emission reductions and prepares a monitoring report. The monitoring officer will receive support from South Pole Carbon Asset Management and its partners. 3. Monitoring Equipment and program The project is connected to the grid through an on-site booster station. There are four invoice meters in total, with two for each of Santangou First Grade Station and Second Grade Station. These meters are located at the high-voltage side of the on-site booster stations. For both stations, one of the two invoice meters is employed to measure the electricity supplied to the grid by the project and the other one is employed to measure electricity imported to the project from the grid during this monitoring period Data Collection: The project owner is responsible for operation of the electric energy meter, and guarantees that the measuring equipments are in good operation and completely sealed. The electricity recorded by the electric energy meter will suffice for the purpose of billing and emission reduction verification. The monitoring process is as follows: i. The project owner reads and checks the electric energy meter and records the data periodically as the firsthand record of the supplied electricity to the grid; ii. The project owner compiles the recorded data of the supplied electricity to the grid monthly and provides the monthly balance sheet of electricity sales to the grid company; 1 There are also meters located at the output of each generator respectively in First station and Second Grade, which are only employed to measure the electricity generated by these power generators. These meters are neither monitored and read by the local grid company for electricity account settlement of every month, nor calibrated by relevant authority at regular intervals just like the invoice meter. Therefore, these meters are not a part of the monitoring plan. 11

12 iii. The grid company confirms the amount of electricity exported by the project owner after the verification, confirmation and acceptance of the electricity data offered by the project owner; iv. The project owner provides an electricity sales invoice to the grid company according to actual amount of electricity delivery reflected by the grid company s confirmation. A copy of the invoice is kept by the project owner; v. The project owner properly keeps the balance sheet of electricity sales to the grid company. The periodical records of the electricity meter s data readings are archived electronically and on paper. If either the project owner or the grid company detects any distortion or mal-function of the electric energy meter resulting in inaccuracy of the metered data, it promptly informs the other party as well as a qualified metrical institute co-authorized by the project owner and the grid company to jointly investigate and solve the problems. Under the above-mentioned unusual circumstances, the parties, based on mutual agreement, determine the amount of supplied electricity to the grid during the period of the occurred distortion or mal-function of the electric energy meter by means of referring to voltage and current data in accordance with relevant rules. The meter reading will be readily accessible for the verification entity. Calibration test records will be maintained for verification. 5. Calibration The verification of the electric energy metering equipment is periodically carried out by a metrical institute authorized by the Administration of Standard Measurement according to relevant National electric industry standards and regulations. After every meter verification process, the electricity metering equipment is sealed, stamped and closed with other measures. Either party shall not unseal, change the structure, layout and connecting wires of the electric metering equipment nor manipulate the electricity meter. Beyond the stipulated verification period, either party of the project owner or the grid company can request a calibration or verification of the electric energy metering equipment at any time. The calibration or verification shall be carried out by a metrical institute authorized by the Administration of Standard Measurement and co-authorized by the project owner and the Grid Company. 6. Data Management The project owner properly keeps the electronic spreadsheets and printout of the monthly records of the amount of supplied electricity to the grid as well as the firsthand record of the electricity supplied to the grid. Besides that, the project owner collects sales receipts for the power delivered to the grid as a cross-check. At the end of each crediting year, a monitoring report is compiled by the project owner. Physical documentation of relevance for the monitoring process, such as paper-based maps and diagrams, are collected in a central place, together with the monitoring plan. In order to facilitate the auditor s reference, monitoring results are indexed. All paper-based information is stored by the project owner. All data records will be kept for a period of 2 years following the end of the crediting period. 12

13 4 QUANTIFICATION OF GHG EMISSION REDUCTIONS AND REMOVALS 4.1 Baseline Emissions According to methodology AMS-I.D (Version 10), the baseline is the kwh produced by the renewable generating unit multiplied by an emission coefficient (measured in kg CO 2 e/kwh) calculated in a transparent and conservative manner as: (a) A combined margin (CM), consisting of the combination of operating margin (OM) and build margin (BM) according to the procedures prescribed in the approved methodology ACM0002. Any of the four procedures to calculate the operating margin can be chosen, but the restrictions to use the Simple OM and the Average OM calculations must be considered. BE y = EG y x EF y Grid Emission Factor was calculated in PDD to be tco 2 e/mwh. This grid emission factor is determined ex-ante and fixed during the crediting period. According to the PDD, the expected annual electricity export to the grid of Santangou First and Second Hydropower Stations Project is 16,957 MWh/year (First Grade: 10,687, Second Grade: 8,550). BE y is calculated as follows: BE y = EG y x EF y = 16,957 MWh/year x tco 2 e/mwh = 18,168 tco 2 e/year In this monitoring period, 11,184 tco 2 e emission reductions are generated in total. 4.2 Project Emissions According to CDM methodologies AMS-I.D. and ACM0002, greenhouse gas emissions from hydropower projects without reservoir (or with a power density of more than 10 W/m 2 of flooded area) are considered to be zero. This project has no reservoir. Hence, the project activity emissions are considered to be zero: Project Emissions = Leakage According to the methodology AMS-I.D, there is neither energy generating equipment transferred from another activity nor existing equipment transferred to another activity, so no leakage is to be considered: Leakage = Summary of GHG Emission Reductions and Removals The calculated emission reductions achieved by the project activity within the covered monitoring period amount to 11,184 tco2e in total. A summary of monitoring data and emission reductions based on aggregated data on a yearly basis are provided in the tables below. 13

However, the calibration certificates of the import invoice meters of the and II Grade stations state the meter accuracy of 1.0. As a result, the level of assurance of emission reductions associated with measured values for the period covered by the calibration is negatively affected. To adjust the measured electricity data which are affected by this meter accuracy issue, a conservative approach is adopted here: Based on the Guidelines for Assessing Compliance with the Calibration Frequency Requirements (Version 01) of EB 52 Annex 60, emission reductions can be discounted by applying the maximum permissible error of the electricity meters measuring electricity values. Here the full accuracy level (1%) of the electricity meter is applied to the increase to the electricity imported from the grid (+1% for imports). So that the net electricity values claiming for emission reductions, which are calculated by deducting electricity imported from electricity exported, will be conservative. 14

However, the calibration certificates of the import invoice meters of the and II Grade stations state the meter accuracy of 1.0. As a result, the level of assurance of emission reductions associated with measured values for the period covered by the calibration is negatively affected. To adjust the measured electricity data which are affected by this meter accuracy issue, a conservative approach is adopted here: Based on the Guidelines for Assessing Compliance with the Calibration Frequency Requirements (Version 01) of EB 52 Annex 60, emission reductions can be discounted by applying the maximum permissible error of the electricity meters measuring electricity values. Here the full accuracy level (1%) of the electricity meter is applied to the increase to the electricity imported from the grid (+1% for imports). So that the net electricity values claiming for emission reductions, which are calculated by deducting electricity imported from electricity exported, will be conservative. 15

16 The invoice meters were read and recorded at 24:00 on every 25th of each month. For segregating the emission reductions from the two calendar years (i.e and 2012), the electricity data from 0:00 26/12/2011 to 24:00 31/12/2011 are collected. The net electricity generated is 44, kwh, and the emission reductions of these six days are calculated as 42 tco2e. The emission reductions generated during this period are accounted as emission reductions in December 2011 (from 26/11/2011 to 31/12/2011), and the said emission reductions are not considered as emission reductions in January 2012 (from 01/01/2012 to 25/01/2012). Data details can be seen in the tables below (data sources have been provided): (3600) I (2400) Santangou I + II ERs (tco2e) Date : :00 Export Meter Reading Export Import Meter Reading Import 2 Export Meter Reading Export Import Meter Reading Import 2 Net The net generation between 0:00 on 26/12/2011 and 24:00 on 31/12/2011 is thus calculated as 42 tco2e. So the emission reductions in December 2011 (26/11/ /12/2011) are = 461 tco2e. And the emission reductions in January 2012 (01/01/ /01/2012) are = 154 tco2e. As the end of this monitoring period is the date of 31/12/2012, but the electricity is settled account at 24:00 on every 25th of every month. Therefore, for calculating the emission reductions from 0:00 26/12/2012 to 24:00 31/12/2012, the electricity data from 0:00 26/12/2012 to 24:00 31/12/2012 are collected from the hydropower station s operation log sheets. The net electricity generation of 140, kwh between 0:00 on 26/12/2012 and 24:00 on 31/12/2012 is added into the December 2012 s net generation. Data details can be seen in the table below (data sources have been provided): (3600) I (2400) + II ERs (tco2e) Date : :00 Export Meter Reading Export Import Meter Reading Import 2 Export Meter Reading Export Import Meter Reading Import 2 Net The emission reductions between 0:00 on 26/12/2012 and 24:00 on 31/12/2012 are 132 tco2e, so emission reductions for December 2012 (from 26/11/2012 to 31/12/2012) are = 1,013 tco2e. 16
