Monitoring Report

Current Status of the Project Pioneer Genco Limited has established a 24.75 MW (3x8.25 MW) Someshwara small hydropower project Scheme at Shivasamudram Village, Hosahalli Panchayath, Malavalli Taluk in Mandya District of Karnataka, India. The project is a run of the river scheme, utilizing a gradient of about 20 meters downstream of the existing 42 MW Shivasamudram hydroelectric project at Gaganchukki branch of Cauvery river. The generated electricity will be exported to a grid system of Karnataka Power Transmission Corporation Limited (KPTCL).

The purpose of this Monitoring Report (MR) is to calculate the Green House Gas (GHG) emission reductions occurred for the net electricity exported to grid. During the reported period the plant displaced 162.65 GWh of net electricity to the KPTCL.

EGy GWh Net electricity export to the grid by the project On-site measurements

The Measured monthly using calibrated meters and aggregated annually. Meters will be calibrated as per industry standards. Sales records to the grid and other records are used to ensure consistency. Electric power sold to the grid will be measured by main meter and check meter by both PGL and KPTCL as specified in the PPA and records maintained. To be cross-checked with monthly invoices or receipts of payments.

Information Used for Emission Reduction Calculations S. No. 1.

Key information/data Source of data/information used for baseline Net Electricity Exported to Monthly Meter Readings recorded and certified by grid KPTCL & plant personnel. Baseline Emission Factor

The project has considered the ex-ante emission factor for the combined margin of the Southern regional grid from Regd. PDD (UNFCCC Project Activity Ref. No.1273) wherein the validated Baseline emission factor is 860.87 tCO2/GWh.

Methods of data transfer and archiving policy The data have been recorded both at the project site as well as at the grid sub-station, which is under the control of KPTCL. The electricity export / import readings have been measured using calibrated trivector meters and recorded manually by the representatives of KPTCL and PGL as a proof of export and import of electricity by the project activities. Those meter readings are the basis for the invoices raised by PGL. These readings are also considered for emission estimations. Sales bills / receipts may be compared as an alternative proof of the electricity exported to the grid. And the data will be stored for a period of 2 years after the crediting period.

GHG Calculations The 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 BEy PEy Ly

= Emission reductions in a given year = Baseline emissions in a given year = Project emissions in a given year = Leakage in a given year

Baseline Emissions The baseline emissions are calculated as follows: BE y = EG y ⋅ EFy

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 the details 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 as leakage 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.

Monitoring Report

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.

As per Hydrology study carried out which forms part of the DPR. Adjusted by taking 3% as Aux. consumption & other losses as projected in the PDD. 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 20081 published by India Meteorological Department, Govt. of India and the Seasonal rainfall2 published by India Meteorological Department, Pune, the cumulative rainfall

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.

Monitoring Report

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.
