a. the performance guarantee parameters. b. the preconditions to the validity of the performance guarantees in production as set

forth below. c. the minimum level of the performance guarantees. d. the procedure for conducting the performance guarantee tests, recording of

measurements / results and calculation for deriving the test results. e. formula for calculation of liquidated damages for failure to attain the performance

guarantees.

6.2 PRE-CONDITIONS

a. The Contractor gives the Performance guarantees (specified herein) for the WTGs, subject to the following precondition being fully satisfied.

b. The APGENCO has engaged the services of NIWE to vet the demonstrated power curve results of the selected WTGs at site conditions in accordance with the method described below:

6.3 THE PROCEDURE FOR POWER CURVE DEMONSTRATION SHALL BE AS

FOLLOWS: Contractor shall provide a Power Curve Guarantee ('PCG') at 95% of the Certified Power

Curve ('CPC') as following methodology

a. APGENCO and Contractor shall jointly decide one designated turbine for the purpose of power curve measurement.

b. Contractor shall install a wind mast (of height equal to the hub height of the above turbine) near the above turbine location at a distance between 2-2.5d (d-Rotor Diameter). This mast shall record wind data at height same as the hub height of the turbine and shall be taken as reference data for the purpose of power curve verification. This mast will be maintained at the site for a period of 12 months for this purpose.


c. The power curve demonstration shall be done as follows: 1. i. The test shall be conducted between April to October ii. The test should result in a minimum 1400 hours of continuous data sets. iii. Should the test fail, then the test shall be repeated once again ( with minimum 1400 hrs of data sets as above) either in the same wind season or in the next windy season between April and October . 2. Calibrated sensors shall be used for measurements. 3. Selection of machine shall be done mutually by the parties. 4. One Number of representative machine shall be selected for the test.

d. The CPC shall then be applied to the above wind speed distribution to arrive at the gross expected energy generation (“GEEG’). The following factors shall then be applied on the GEEG to arrive at the net expected energy generation (‘NEEG’).

i. The air density correction factor will be applied on certified power curve. ii. Array losses will be calculated by software for test period and applied. iii. Grid availability during test period iv. Machine availability during test period. v. Uncertainty factors in terms RSS, of 3 -5 % for wind measurement and 5-7 % for

power curve will be applied in the calculations.

e. The NEEG thus arrived shall be verified against actual energy generated by the turbine as recorded by the machine meter in the control panel. If the actual generation as recorded by the machine meter is equal to or above 95% of the NEEG, then the turbine is deemed to have met with the power curve guarantee.

In an event the actual generation by the Project is lower than 95 % of generation as per certified power curve, the contractor shall compensate M/s APGENCO as per the details given in the tender document.

6.4 The annual energy output in kWh shall be evaluated and validated by M/s. NIWE.

6.5 FAILURE IN GUARANTEES AND LIQUIDATED DAMAGES

For every 1% (or part thereof) shortfall in actual generation than guaranteed 95% NEEG, the Contractor shall pay to APGENCO @ 1% (one percent) of the Contract price. In case the actual generation as recorded at the WEG meter is less than 90 %, the contractor shall rectify the defects in all WEGs or replace all the WEGs as the case may be in the manner that power generation is not less than 95 % of NEEG. The power curve performance test should be repeated again after rectification. In case the actual generation is equivalent or more than 95 % of NEEG the test will be deemed to have passed the performance test. In this case, the Contractor shall compensate APGENCO for the actual revenue loss during the period when generation is lower due to performance of the WEG. The revenue loss will be calculated considering the contractor’s obligation at 100% NEEG.

6.6.1 Failure to Attain Power Curve Generation Guarantee (PCGG) on total plant. 6.6.1.1 For any shortfall in PCGG during the warranty/defects liability period, the liquidated

damages not by way of penalty shall be recovered from Contractor as described below:

Annexure: V/1

METHOD OF ENERGY ESTIMATION NIWE, on receipt of the project details would:

a. Cross check the data submitted b. Carry out an independent analysis c. Determine possible outputs d. Conduct site visit e. Prepare a report

The WAsP model 10.2/11.0 /Windsim/Meteodyn will be used for generating the spatial wind environment of the Region of Interest (Wind Atlas Analysis and Application Program (WAsP) is a PC- program developed by the Wind Energy and Atmospheric Physics Department, RISO National Laboratory, Denmark for the vertical and horizontal extrapolation of wind data. It is a powerful tool for wind data analysis, wind atlas generation, wind climate estimation and estimation of wind power potential of a site.) The inputs supplied by the bidder after due validation & verification will be used for energy estimation. Actual details of the terrain characteristics will be collected during the visit to the site and its surroundings. Factors Affecting Net Generation

When wind energy estimations are to be made, potential sources of energy losses must be considered on a site specific basis. Specific source of energy losses other than those associated with wake effects are described below. Table 1 gives standard correction factors in the annual energy estimation. P50 values arrived with respect to standard correction factors. Corrections will also be made with Rugged Indices where slope is more than 30 % with reference to reference mast. If the proposed site is in and around another wind power plant, additional wake effects of 3-8 % will be taken in to the account. If the contractors provides the wind power plants co-ordinates in and around the proposed site, the actual wake loss will be taken for computation. The surrounding turbine co-ordinates will be verified by the consultant, accordingly the wake loss will be taken for computation.

Table I - Standard correction factors in the annual energy estimation

No. Details % 1 Grid availability 0.95 2 Machine availability 0.95 3 Electrical losses 3 % 4 Air density correction As per the site temp and

pressure


5 Wind data discrepancy if any As per the site data

6 Wake losses 3-5%or actual

Total 70 to 80%

. Uncertainty Factors The uncertainty analysis is an important part of any assessment of the long-term energy production of a wind power plant. The uncertainty of a production estimate is very dependent on the local wind climate, the topography, the data acquisition system, the period of data collection, the limitations of the software used for the estimation and power curve. To give an exact estimate of the uncertainty is not possible. Uncertainty factor as per the site(an uncertainty Factor of 0.5% will be taken for every 1km in a homogeneous beyond 5km and 0.5% for every 500m in complex terrain. Apart from this, 1% will be taken for every 10m if the measurement height is not the height of hub). However probable uncertainty factors for proposed wind power plant have been estimated and taken into account while fixing up the generation levels. Details are given in the Table 2.

4 Extrapolation (horizontal) %

5 Input file accuracy (Orography + Roughness)

%

6 Power curve %

7 Model uncertainty %

RSS Value (Approximately) 8-20 %

The energy estimation from given number of machines will be generated from the micro-siting details supplied by the bidder after verifying all inputs. The generation details will be given for entire machines with different confidence levels (P50, P75, P90 and P95) P75, P90 and P95 will be derived with uncertainty factors. It is recommended to consider park average only for any decision as uncertainties would be more in selecting individual machine.
