1: The PoA-DD establishes that the sampling plan shall have sampling frames taking into account country, fuel type, user and stove type. Three sampling frames were established to determine parameter 'Efficiency of the system being deployed as part of the project activity'. However, for the other parameters (Stove operation factor; Fraction of end users that are still using baseline stoves; and The amount of woody biomass consumption that is consumed through the continued use of old stoves), there were only two sampling frames, one for charcoal and one for woodfuel. It has not been demonstrated that:
(i) The efficiency of the two types of charcoal stoves are within +/-10%. As per the specification, efficiency of stove CH5300 is 35.7%. The +/-10% range of this efficiency would be 32.13% - 39.27%, whereas the efficiency of stove CH2300 is 39.4%;
(ii) The two types of charcoal stove have the same feature. The PoA-DD has provided an example of two types of stove having the same efficiency but they are considered different due to the suitability of different shape of pot's bottom. Furthermore, it is observed from the figures in page 6 of the monitoring report that CH5300 stove has air grill whereas CH2300 stove does not.
Please refer to paragraph 345 of VVS-PoA (version 01.0).
2: As per the MR, the surveys and WBTs were conducted during March - May 2018. The DOE needs to clarify how it concluded that the devices were duly calibrated prior to the water boiling test survey reported in the survey forms, as the mini-thermometer and mass balance were calibration on 08/05/2018.
3: Some households are observed having more-than-one stoves as per the 'CPA Distribution Data'. For example, the same households (referring to the same CUSTOMER NAME, same CUSTOMER ADDRESS, same CITY OR VILLAGE, same TELEPHONE NUMBER) are observed to have 5 stoves, 8 stoves, 18 stoves, or even 41 stoves (i.e. MRS O.K ROTIMI). The parameter ex-ante parameter Qbiomass (Annual average biomass consumption per appliance, i.e. 4.94 and 4.50 Tonne/year/stove for CPA4 and CPA5 respectively) was determined based on biomass consumption at household level. For example in CPA4, the value 4.94 was calculated from average fuelwood consumption per capita of 0.99 tonne/y, multiplied by average size household in Nigeria of 5 persons/household. The resulting unit of this calculation would be 'tonne/y/household'. However, unit of this parameter the CPA-DDs is 'tonne/y/stove', which implies that there will be one stove per household. . Given the fact above, the DOE shall provide information on how it has verified the appropriateness of applying the values 4.94 and 4.50 Tonne/year/stove for CPA4 and CPA5 respectively in determining the emission reductions.
Please refer to paragraph 358(d) of VVS-PoA (version 01.0).
