10.

GHG CalculationsThe following formula is adopted for calculating emission reductions generated by the project activity:

The emission reductions for a given year are baseline emissions minus the project emissions and

leakage.

ERy= BEy- PEy- Ly

Where ERy = Emission reductions ina given yearBEy = Baseline emissions ina given yearPEy = Project emissions ina given year

Ly = Leakage ina given year

Baseline Emissions

The baseline emissions are calculated as follows:

yyy EFEGBE =

Where EGy = Net electricity export to grid in a given year (GWh)EFy is = Emission factor for a given year (tCO2/GWh)

As mentioned under sec. B.2 of registered PDD (UNFCCC Project Activity Ref. No.1273), the project has

considered the ex-ante emission factor for the combined margin of the Southern regional grid and thedetails are furnished below:

Operating Margin (OM) in t CO2/ GWh 1003.76

Build Margin (BM), in t CO2/ GWh 717.98

Combined Margin (CM)Simple average of OM and BM in t CO2/ GWh

860.87

Project emissions (PEy):

The project emissions are considered zero.

Leakage

As specified in ACM 0002, project participants do not need to consider these emission sources asleakage in applying this methodology. Hence the leakage emissions are considered zero.

Using the above formulas, the Emission reductions from the project activity are shown below.

Net emission reductions for the reported period = (140020 105883) x 100 / 105883

= 32.24%

The net emission reductions for the reported period is + 32.24% more than the estimated in the

registered PDD due to more net electricity generation (exported to grid).

The reasons for the excess net electricity generations are

Excess rainfall in the catchments area of river Power generation during the lean / off season Reduction in the Losses

The uncertainty relating to water discharges was in fact one of the key risk factors affecting the project.

Most of the above factors keep changing on year to year basis. Due to favorable discharges from the

above-mentioned factors and availability of plant, which could not be relied upon at the time of PDD

writing, actual water flows during the monitored period were higher and thereby the power generations

are higher than the estimated power generations. Justification for excess net electricity generations is

furnished as Annex-2.

The detailed calculation of emission reductions is provided in excel spread sheet.

12. Measures to ensure the results/uncertainty analysis

The energy exported by Someshwara small hydropower project is recorded from independent main

meter installed at the 66/11 KV substation. In the event, the Main Meter is not in operation, the reading

from Check Meter is used for billing.

The calibration of monitoring equipment is being maintained as per the requirement of Electricity Board

and the same is being done regularly. Power generation, export, and energy import are being recorded

daily and the same is being verified by the respective officials. Both meters are of same specifications &

frequency and approved by KPTCL. The accuracy clause of these meters is 0.2.

Justification for Excess Net Electricity Generation during the Reported Period

The projected power generation (in GWh) in the Detailed Project Report (DPR), as reflected in the

registered PDD and the actual generations during the reported period are furnished below:

a As per Hydrology study carried out which forms part of the DPR.b Adjusted by taking 3% as Aux. consumption & other losses as projected in the PDD.c Computed based on Monthly electricity readings recorded & certified by KPTCL personnel.

The first reason for the excess electricity generation compared to the projection in the PDD is that the

rainfall in the catchment area of rivers Cauvery and Kabini was above normal for the region and also

due to consecutive depressions in the ocean of Bay of Bengal and Arabian sea which resulted in heavy

rain fall during monsoon (June to September).

As per Annual climate summary 20081published by India Meteorological Department, Govt. of India

and the Seasonal rainfall2published by India Meteorological Department, Pune, the cumulative rainfall

in the catchments area of Cauvery river for the reported period are above of its Long Period Average

(LPA). The details of rain fall in South Interior Karnataka (Covered Cauvery river catchments area)

Apart from the above, the pp also reviewed the discharge data was recorded for the period of 10 years

i.e. from 1985-86 to 1995-96 at Dhanagere anicut by Central Water Commission (CWC) at time of

Detailed project report (DPR) and in the absence of relevant data for the following are not accounted in

the estimated average annual export power to grid of 81.48 MW.

No corrections to the recorded data for the additional catchment area made at Dhanagere anicut.

The releases into Dhanagere irrigation canal

The uncertainty relating to water discharges was in fact one of the key risk factors affecting the project.

The investment decision, and hence the projected power generation in the PDD, were based on a

conservative average water discharge level of 56.0 cubic meters per second (cumec) as reflected in

PDD, corresponding to an average plant load factor of 38.7%.

The Second reason for net electricity generation is that the Actual losses recorded during the reported

period and the projected losses in the registered PDD are 1.8% against 3% which was projected in the

registered PDD.

In light of higher water flows in the river from the above-mentioned factors which could not be relied

upon at the time of PDD writing and reduction in auxiliary power including losses, the net electricity

generations are about +32.24% higher than the estimated electricity generations in the registered PDD.

As there is no restriction on the plant load factor (PLF) from the state electricity board authorities

(Karnataka Power Transmission Corporation Limited), the project activity has utilized the available

water flows and generated excess electricity generation is deemed acceptable.
