Monitoring Meter: A bi-directional revenue meter Ma 1 was equipped at the project site. It measures both the amount of electricity exported to the grid 1 According to the MR of first verification period, the meters M1 and M2 installed on the two 0.4kv transmission lines were used for monitoring the electricity generated by the generators as the reference for the readings of M3. As the accuracy of M1 and M2 was 1.0 which was too low, they were not allowed by the grid company to record electricity. If the main meter M3 was malfunctioned, no emission reduction would be claimed. Thus, M1 and M2 was missing in the following MR accordingly compared with the registered PDD. Meanwhile, according to the MR of fourth verification period, on 22/12/2013, the new revenue meter Ma was equipped and replaced the old one M3 which was removed

10 (EG export,y ) and the amount of electricity imported from the grid (EG import,y ). The readings of Ma should be recorded on a monthly basis as a monthly electricity transaction notes. The electricity sales receipt is served as additional check for quality control. The accuracy of Ma is 0.5s. If the main meter Ma is malfunctioned, no emission reduction will be claimed. During this verification period from 28/07/2014 to 09/02/2016, there is no failure of meter took place. The calibration of the meter has been done by authority in line with the national Chinese standard DL/T The monitoring data including paper and electronic version, electricity sales/purchase receipts of every month and other GS related documents should be archived by the project owner. And all of the materials will be kept until 2 years after the end of the total credit period of the project.

12 3.4 Emission reductions Calculation Baseline Emissions (BE y ) The baseline emissions can be calculated as follows: BE EG EF y PJ, y grid, CM, y Where : BE y = Baseline Emissions in year y; (tco 2 e/yr). EG PJ,y = Quantity of net electricity generation supplied by the project plant/unit to the grid in year (MWh/yr). EG PJ,y = EG export,y - EG import,y EF grid,cm,y = Combined margin CO 2 emission factor in year y (tco 2 e/mwh). According to the registered PDD, EF grid,cm,y = tco 2 e/mwh Project Emissions (PE y ) According to ACM0002 (Version ), as a hydropower project the power density of the project is respectively 27.9 W/m 2, 28.4 W/m 2 and 27.7 W/m 2 covering the monitoring period, greater than 10 W/m 2, thus the project emissions resulting from the project are zero. PE y =0 tco 2 e. Leakage (LE y ) According to ACM0002 (Version ), there is no leakage considered, i.e. LE y =0 tco 2 e. Emission Reductions (ER y ) The emission reductions (ER y ) by the project during a given year y are the difference among baseline emissions (BE y ), project emissions (PE y ) and emissions due to leakage (LE y ). The final GHG emission reductions are calculated as follows: ERy BEy PEy LEy Detailed amounts of the recorded electricity generated from the project and calculations of emission reductions are listed below:

For the emission reductions of year 2014 (28/07/ /12/2014, 153 days), the estimated emission reductions are calculated as 2,583 tco 2 e/365d 153d=1,083 tco 2 e, which is higher than the actual value 640 tco 2 e. For the emission reductions of year 2015 (28/12/ /12/2015, 365 days), the estimated emission reductions are calculated as 2,

15 tco 2 e/365d 365d=2,583 tco 2 e. The actual emission reduction of 2,646 tco 2 e in 2015 is 2.43% 2 higher than the estimated. The reason is that during the rainy season in 2015 the precipitation is a little bit higher than normal year 3. For the emission reductions of year 2016 (28/12/ /02/2016, 44 days), the estimated emission reductions are calculated as 2,583 tco 2 e/365d 44d=311 tco 2 e. Thus, the actual emission reduction of 3,540 tco 2 e during the monitoring period from 28/07/2014 to 09/02/2016 is 10.91% 4 lower than the estimated value of 3,977 tco 2 e. 4.
