5. General description of the project:

5.1 Project Activity:

The candidate CDM project will generate electricity from WEGs in the Goyal MG Gases Pvt. Ltd.

Wind Park. The project activity has been essentially conceived for the sale of generated

electricity to state electricity utility (Tamil Nadu Electricity Board). The wind power will be

wheeled utilizing the regional grid (Southern Region Electricity Grid), and will be supplied to the

local consumers drawing electricity from the grid. Since wind based electricity generation is

GHG emissions free, the electrical power generated will save the anthropogenic Green House Gas

(GHG) emissions generated by the fossil fuel based thermal power stations comprising coal,

diesel, furnace oil and gas.

The project activity started in March 2004 and was estimated to generate approximately 30

million kWh per year, contributing an estimated reduction of 279630 tCO2e over the ten year

crediting period of the project from 2004-2014. This reduction is the result of displacement of

fossil fuel fired power plants that would otherwise have delivered the electricity to Southern

Region Grid in the absence of the project activity.

5.2 Technical description of the project:

Location of project activity: The project activity is spread across three locations in Tamil Nadu

with the following geographical positioning:

Coimbatore: 11 N (Latitude) and 77 E (Longitude)

Erode: 11 20 N (Latitude) and 77 46 E (Longitude)

Tirunelveli: 8 44 N (Latitude) and 77 44 E (Longitude)

Technology employed by the project activity:

The project activity envisages installation of small sized WEGs of individual capacity 225 kW

supplied by NEPC. The salient features of the technology are furnished below.

The project activity leads to the promotion of small sized Wind Electric Generators (WEGs) into

the region, demonstrating the success of wind based renewable energy generation, which is fed

into the nearest sub-station (part of the Southern Regional Grid), thus increasing energy

availability and improving quality of power under the service area of the substation. Hence, the

project leads to technological well being.

No technology transfer from other countries is involved in this project activity.

6. Monitoring methodology & Plan:

The project activity meets the eligibility criteria to use simplified modalities and procedure for

small-scale CDM project activities as set out in paragraph 6 (c) of decision 17/CP.7.

7.1 Calibration / Maintenance of Measuring and Analytical Equipments

Training

All incoming new incumbents are given formal class room type structured training at windfarm

sites. Various topics covered are as follows:

- Import knowledge about technical details of various components and parts of windmills- Teach the importance and functional details of each component of the windmill.

- Impart training regarding normal starting procedure, normal stopping procedure, emergency

stopping procedure and procedure for handling windmill and its switchyard, emergency etc.

- Impart knowledge about mechanical, electrical and electronics / instrumentation related

preventive and predictive maintenance schedule, procedure for undertaking routine

maintenance and keeping up to date maintenance records, thereto.

- Procedure for diagnostic approach for analyzing defects and the procedure for undertaking

break down repairs.

- Keeping close watch and control reactive power import / export from/to TNEB grid.

Commensurate with the wind speed and wind power generated there from.

- Monitoring and record keeping of windfarm performance parameters through Centralized

Monitoring System (CMS)- Imbibe safety procedures.

- Ensuring study of technical literature of various parts and components of the windfarms.

- Preparation of daily generation report for the wind energy generated, record defects or

reasons for low generation, if any instituting corrective measures to improve generation,

where feasible.

- Procedure for drawal and use of spares, consumables and other materials for repairs and

maintenance of windmills.- Imparting training on various associated aspects for smooth operation & maintenance of

windmills so as to ensure minimum down time and enhance their MTBF.

Energy Meter

The measurement of electricity is carried out as per the prevailing guidelines of the stateelectricity regulatory commission, which mandates implementation of 0.5 accuracy class meters

at grid interconnection point for measurement of generated electricity. The transmission loss

incurred till the metering point is to be absorbed by the project proponent and the payment is

made on the basis of electricity fed into the grid.

- The primary recording of the electricity fed to the state utility grid will be carried out jointly

at the incoming feeder of the state electricity utility (TNEB). Machines for sale to utility will

be connected to the feeder.

- The joint measurement will be carried out once in a month in presence of both parties (the

developers representative and officials of the state power utility). Both parties will sign the

recorded reading.

- In exceptional circumstances of failure of metering system, immediate replacement is carried

on 24 * 7 basis.- The meter is calibrated every 6 months as per the TNEB statutory laid down periodicity.

- As per TNEB laid down procedure, the defective main energy meter is always replaced by

the TNEB accredited representative in presence of the Companys personnel by a spare

energy meter.

- The defective energy meter is taken away by the accredited TNEB representative to their

laboratory for retrieval of recorded data and issue of certificate for the last recorded readings

thereto.


7/12

- The measurement is thus always on the lower side, and is therefore conservative with respect

to generation of electricity as well as GHG abetment.

Other Maintenance and upkeep practices include:

- Regular calibration of the energy meters

- Calibration of other monitoring equipment, in all the wind farms.

7.2 Environmental Impact

1. The electricity from wind electricity generator has no negative environmental impacts.

2. As per the Schedule 1 of Ministry of Environment and Forests (Government of India)

notification dated January 27, 1994, - 30 activities are required to undertake environmental

impact assessment studies. The details of these activities are available at:

http://envfor.nic.in/divisions/iass/notif/eia.htm

3. The proposed project doesnt fall under the list of activities requiring EIA as it will not

involve any negative environmental impacts, because the WEGs installed for generation of

power use wind (cleanest possible source of renewable energy).

8. GHG Calculations

8.1 Project Activity Emissions: Nil

Emissions by sources of GHGs due to the project activity within the project boundary are zero

since wind power is a GHG emission free source of energy.

8.2 Leakage: Nil

This is not applicable as the renewable energy technology used is not equipment transferred

from another activity. Therefore, as per the simplified procedures for SSC project activities, no

leakage calculation is required.

There is no alternate fuel which can generate electricity from the installed plant and machinery

in absence of wind.

8.3 Baseline Emissions

The wind power project uses the Combined Margin methodology as suggested in the Appendix

B of the simplified modalities and procedures for small-scale CDM project activities.

The total baseline emissions BEy (tCO2/yr) = EGy * EFy

Where

BEy = Baseline emissions in year y (tCO2).

EGy (MWh/yr) = Electricity generated by the project in year y;

EFy

= Combined margin emissions factor (Baseline emission factor) for the year y

(tCO2/MWh).


8/12

The emission factor EFy of the Western Region Grid is a fixed value over the projects crediting

period and is calculated as the weighted average of the Operating Margin emission factor

(EFOM, y) and the Build Margin emission factor (EFBM,y):

EFy = wOM EFOM,y + wBM .EFBM,y

Where the weights wOM and wBM, are 75% and 25%, and EFOM, y and EFBM, y are the OperatingMargin and Build Margin emission factors respectively calculated in the following paragraph.

The emission factor EFy is estimated to be0.9321 tCO2/MWh.

The Operating Margin is the weighted average emissions of all generating sources serving the

Northern Grid excluding hydro, geothermal, wind, low-cost biomass, nuclear and solar

generation. It is derived from the following equation:

EFOM, simple, y = Fi, j, y COEFi, jGENj, y

where,Fi, j, y is the amount of fuel i (in a mass or volume unit) consumed by relevant power sources j

in year(s) y,

j refers to the power sources delivering electricity to the grid, not including low-operating cost

and must-run power plants, and including imports to the grid.

COEFi,j y is the CO2 emission coefficient of fuel i (tCO2 / mass or volume unit of the fuel),taking into account the carbon content of the fuels used by relevant power sources j and the

percent oxidation of the fuel in year(s) y, and

GEN j, y is the electricity (MWh) delivered to the grid by source j.

The CO2 emission coefficient COEFi is obtained as

COEFi = NCVi * EFCO2, i * OXIDiwhere:

NCVi is the net calorific value (energy content) per mass or volume unit of a fuel i,

OXIDi is the oxidation factor of the fuel (see page 1.29 in the 1996 Revised IPCC Guidelines

for default values),

EFCO2,i is the CO2 emission factor per unit of energy of the fuel i.

The EFOM,Y is estimated to be 1.00349 tCO2/MWh (based on three years average).

The Build Margin emission factor (EFBM,y) is calculated as the generation weighted average

emission factor (tCO2/MWh) of a sample of power plants m, as follows:

EFBM,y = Fi, m, y .COEFi, mGENm,y

WhereFi, m,y = quantity of fuel i used in plant m (kt/yr) in year y


9/12

COEFi, m = carbon emissions factor for fuel i in plant m (tCO2/kt), taking into account the

carbon content of the fuels by power sources and the percent oxidation of the fuel

GENm, y = annual generation from plant j (MWh/yr) in year y

The EFBM,y is estimated as 0.7179 tCO2/MWh (with sample group m constituting most recent

capacity additions to the grid comprising 20% of the system generation).

The baseline emissions are estimated as the product of the electricity generated by the projectactivity and the Emission factor of the regional electricity grid as calculated above.
