2.1.2 About GSECL

Gujarat State Electricity Corporation Limited (GSECL) was incorporated in August 1993 and is registered under the Companies Act, 1956 with the objectives to initiate a process of restructuring of Power Sector and to mobilize resources from the market for adding to the generating capacity of the State and improving the quality and cost of existing generation. The Company was promoted by erstwhile Gujarat Electricity Board (GEB) as it’s wholly owned subsidiary in the context of liberalization and as a part of efforts towards restructuring of the Power Sector. The Memorandum and Articles of Association of GSECL envisage a wide spectrum of activities to improve the electricity infrastructure of Gujarat. GSECL has initiated its activities in the field of Generation of Power. The Government of Gujarat (GoG) has also given to the GSECL the status of Independent Power Producer (IPP) with approval to undertake new power projects. The Company commenced it is commercial operation in the year 1998. However, the operations of GSECL were limited to Power Stations units Gandhinagar #5, Wanakbori #7, Utran GBPS & Dhuvaran CCPP till the complete unbundling of erstwhile GEB was undertaken, i.e. up to 31st March 2005. As a part of the reform process, the Government of Gujarat has unbundled the various functions of GEB. As a result of this unbundling, Gujarat State Electricity Corporation Limited (GSECL) has taken up the responsibility of electricity generation. Electricity Transmission has been entrusted to the already existing company - GETCO. Distribution network in the state has been split up among four distribution companies, which cater to the northern, central, southern, and western parts of the state respectively. All these companies have been structured as subsidiaries of a holding company, Gujarat Urja Vikas Nigam Limited (GUVNL). GUVNL is also the single bulk buyer in the state as well as the bulk supplier to distribution companies. It will also carry out the trading function in the state. As part of Clean-Green Energy programmed, GSECL has also initiated process for installing solar panels on roof-top at identified locations within GSECL / GUVNL premises. Solar energy based power plant of 1 MW on Narmada branch canal near village Chandrasan near Sanand has commissioned in 2012. The innovative idea of merging Jal Shakti with Urja Shakti by installating Solar panels on Canal-top has made this project one of its kind in the world. Solar panels with different cell technology are integrated at single site at Gandhinagar with 1 MW Capacity. GSECL has also installed 10 MW Solar PV Power Plant under Jawaharlal Nehru National Solar Mission Phase II Batch I at Gujarat Solar Park, Village Charanka, Taluka Santalpur, District Patan, in the GIPCL/ Solar/ EPC/ 2017/2x75 MW (AC) Solar PV/ Rev. 1.0 dated 18th December, 2017.

in the Contractor’s bill or reimbursed. In case the Contractor fails to meet the NEEGG at the end of the year then above-mentioned penalty shall be adjusted from the penalty calculated at the end of the year for the shortfall in the generation so that there is no duplication of penalty for the same loss of generation. The first 48 hours shall not be considered for the penalty in case of any defect.

6.12.5 In case the Project fails to generate any power continuously for 6 months any time during the O&M period, it shall be considered as an “Event of Default”. 6.12.6 Upon occurrence of any Event of Default mentioned in Clause 6.12.4 herein above, GIPCL/GSECL shall have the right to encash the entire amount of O&M Bank Guarantee submitted by the Contractor and withheld any other pending payment. 6.12.7 The Owner reserves the right to perform random audits of weather monitoring system of the plant anytime during the entire O&M period. If any discrepancy is found between the measured parameters, the difference between the measured parameters by GIPCL/GSECL from secondary sources and the weather monitoring system installed by the Contractor at the site will be factored in calculating the adjusted NEEGG during the entire year. However, GIPCL/GSECL will have the final authority to decide on this matter. B. Incentive for Early Completion & Higher Generation during O & M 6.12.8 Incentive for Early Completion (COD with GEDA/GUVNL): Twenty (20) paisa per unit incentive shall be payable for successfully early completion of the Project subject to early acceptance of COD by GUVNL and receipt of payment to GIPCL/GSECL 6.12.9 Incentive for higher Generation during O & M: To encourage efficient Operation and Maintenance of the Solar Plant Incentive as per following shall be considered by GIPCL / GSECL. If for any Contract Year, it is found that the “Actual Delivered Energy” is higher than ‘Corrected NEEGG’ for the particular year, the Owner shall pay incentive to EPC Contractor equivalent to ten (10) Paisa per kWh of excess actual generation during the year.

Appendix 16: Procedure for Performance Testing

Part A: Solar PV power plant Net power generation 1. The Contractor shall quote the ‘Net Electrical Energy Generation Guarantee” for annual basis considering the Reference Global Average Radiation indicated in this Tender. 2.

The Contractor shall demonstrate “Actual Delivered Energy” at metering point (GETCO end sub-station) as compared to the ‘Base NEEGG’ for every year from the date of starting of O&M Period.

3. The quoted NEEGG as in Table no. 15 B in Appendix 15 for any year shall be permitted with maximum 1 % degradation factor in previous year generation. 4. The quoted NEEGG will be used for the calculating CUF. 5. The Bidder shall clearly mention the technology used i.e. fixed/tilt or seasonal tracker (please specify) as per Table given in Appendix 4. Part B: Operational Acceptance Test Procedure Performance Ratio (PR) - Test Procedure 1. Performance Ratio as determined through the PR Test Procedure specified here should not be less than 0.75 for Operational Acceptance Test. 2. The Performance Ratio Test to prove the guaranteed performance parameters of the power plant shall be conducted at site by the Contractor in presence of the Owner. The Contractor's Engineer shall make the plant ready to conduct such tests. The Operational Acceptance Test shall be commenced, within a period of one (1) month after successful Commissioning and, there will be continuous monitoring of the performance for 30 days. Any extension of time beyond the above one (1) month shall be mutually agreed upon. These tests shall be binding on both the parties to the Contract to determine compliance of the equipment with the guaranteed performance parameters. This monitoring will be performed on the site under the supervision of the Owner/ Owner's engineer. 3. The test will consist of guaranteeing the correct operation of the plant over 30 days, by the way of the efficiency rate (performance ratio) based on the reading of the energy produced and delivered to the grid and the average incident solar radiation. During this period of 30 days, any 5 (five) instances of 15 (fifteen) minutes shall be taken to calculate the instantaneous Performance Ratio of 15 minutes block as per the formula given below in

GIPCL/ Solar/ EPC/ 2017/2x75 MW (AC) Solar PV/ Rev. 1.0 dated 18th December 2017.

(Sign and Seal of Bidder)

Page 249 of 297

Point No. 5. If the PR of these fives instances is above 75%, then Operational Acceptance Test (OAT) shall be considered successful.

4. PR shall be demonstrated against the installed DC Capacity. 5. The Efficiency or performance ratio (PR) of the PV Plant is calculated as follows (according to IEC 61724) Performance Ratio (PR) = YA / YR Where; YA = Final (actual measured) PV system yield in kilo-watt hours at the point of measurement during the testing period, and YR = Reference yield calculated as the product of the insolation on the plane of the collector (i.e. PV modules) in kWh/ m2 during the testing period and the installed DC capacity of the plant in kW. = [Insolation on the plane of the collector (i.e. PV modules) in kWh/ m2 during the testing period] x Installed DC Capacity = (kWh/m2) x Installed DC Capacity Monitoring System for PR Verification The following instrumentation will be used to determine the Solar Plant Performance: 

Power Meter at the delivery point.



Power Meter for each inverter for reference only.



One nos. calibrated pyranometer to determine irradiance on the plane of array (with a target measurement uncertainty of ± 2).



One nos. calibrated pyranometer to determine irradiance on horizontal plane (with a target measurement uncertainty of ± 2)



Two nos. thermocouples to measure module temperature with a measurement uncertainty of ±1 °C.



Shielded ventilated thermocouple with a measurement accuracy of ±1°C.



An anemometer mounted on a 10m mast to measure wind speed (without additional shadowing on modules).

Page 250 of 297



Data measurement shall be witnessed in the format mutually agreed before the start of PR test by the employer and the contractor jointly for the said period.



The Contractor shall show the specified PR for Operational Acceptance.

Part C: The procedure for Performance Guarantee Test (PGT) - cum- Final Acceptance Test- shall be as follows: 1. A weather station with a calibrated pyranometer shall be installed by the Contractor at the location mutually agreed by the Contractor and GIPCL/GSECL. The test report for the calibration shall be submitted by the Contractor for approval by GIPCL/GSECL. The calibration should be traceable to a national/international laboratory. The output of this pyranometer for shall be logged in the SCADA system. 2. In case the pyranometer is found to be working erratically then immediately the Contractor shall take necessary steps to rectify and/or recalibrate the instrument to the satisfaction of GIPCL/GSECL. However, for the dispute period for which such error has occurred and until the instrument is recalibrated to the satisfaction of GIPCL/GSECL, data from any one of the following list of sources as decided by GIPCL/GSECL will be used: i.

A separate pyranometer installed by the Owner near the site, if available

ii.

Average of two closest solar power projects, as identified by GIPCL/GSECL

iii. Nearest MNRE weather station 3. “Actual Delivered Energy” from the plant supplied by the Contractor shall be noted for every month and summed up for entire year. For this purpose, the net delivered energy at the metering point shall be taken into account. 4. The measured value of energy at step (3) shall be compared with ‘Base NEEGG’ and hence with ‘Base CUF’ value. “Base NEEGG/ CUF” for a month is calculated by using the NEEGG quoted in the offer by the Contractor adjusted with a correction factor to take into account the actual average global solar radiation measured by the calibrated pyranometer for that year. 5. Further, if the plant is not able to achieve the calculated Base NEEGG/CUF during PGT and O&M period and there is a shortfall in energy generation, then the Contractor shall be penalized as per relevant Clause of the Tender. 6. The Contractor shall share with GIPCL/GSECL all the radiation, generation, etc. parameters details and all other factors necessary for GIPCL/GSECL to corroborate the

estimate. GSECL has the right to cross verify data submitted by the Contractor by all possible means/sources.

Following factors may be noted for computing the Base NEEGG/ CUF and PR Test: 7. Effect due to variation in annual insolation shall only be considered for computing the Base NEEGG/ CUF. 8. Effect due to variation of meteorological parameters e.g. ambient temperature, wind speed, humidity etc. shall not be considered. 9. Generation loss due to grid outage (or power evacuation system which is not in the scope of the Contractor): The measured global solar radiation of the period of the outage of the power evacuation system shall be excluded to calculate average global solar radiation for the period of PGT and O&M. Solar Radiation: Ideally, actual measurement of solar radiation at the site is desirable for estimating the projected power output since solar energy is the raw material for power generation. It may be noted that the annual average solar radiation measurement even for 1-2 years is not sufficient. World over, an average radiation value for at least 8-10 years is used for solar power project designing since climatic variations are quite wide year-to-year. Under such a situation, the prevailing practice world over is to develop software which uses satellite measured solar radiation and matches it with the actual ground measured data for the particular site where actual data has been obtained for many years. There are radiation data from reputed agencies like NASA available. The derived values are tabulated below: Month January February March April May June July August September October November December Annual

GHI GHI (kWh/m2/month) 130 135 176 191 207 185 157 149 156 151 127 122 1,886

The above radiation data shall be used by the Bidder to calculate NEEGG. This radiation data is for evaluation purpose. However, for every year actual radiation shall be considered to calculate the NEEGG by the Bidder. Illustration: If the GHI of a year is more or less then the reference GHI then NEEGG will be calculated as follows: NEEGG = (Actual GHI x NEEGG guaranteed by contractor on reference GHI)/ (Reference GHI) NEEGG guaranteed by Contractor = 30,22,20,000 KWh Reference GHI= 1886 KWh/m2 per annum For Example: Case A) for higher irradiation: If Actual GHI = 1900 kWh/m2 per annum then NEEGG will be: NEEGG = (1900 x 30,22,20,000)/ 1886 NEEGG = 30,44,63,415 KWh/ Annum Case B) for lower irradiation: If Actual GHI = 1850 kWh/m2 per annum then NEEGG will be: NEEGG = (1850 x 30,22,20,000)/ 1886 NEEGG = 29,64,51,220 KWh/ Annum

4. Geology: 4.1. The study area is a part of North Gujarat alluvial plain and geologically it falls within the vast marshy, saline tract of Holocene sedimentation. The area is formed of tidal mudflats and series of offshore sandbars. Geologically the area is covered with saline tract of brownish grey silt, clay, sand, and murram at depth. In the Patan district nearly 90% of soil is sandy. The alluvial soils are found in the talukas of Santalpur and Radhanpur.

Page 270 of 297

4.2. At the site, rocky outcrops have been witnessed in the south and south west direction whereas alluvial thickness increases towards the North.

5. Drainage: 5.1. The site does not have any perennial drainage system. 5.2. One seasonal nalah is traversing the site in north-south direction sloping towards the Little Rann of Kutch. This nalah culminates into a reservoir which is located at the boundary of little Rann of Kutch. This nalah is used only during the monsoon season to drain the excess water of the catchment area. 6. Local Weather Conditions: 6.1. Weather is predominantly dry and arid. 6.2. The general weather characteristics obtained from the Deesa station of IMD, which is about 30km from the site, are as follows:

6.3. The site receives maximum rainfall between July to August. During these two months, continuous heavy downpour happens over a period of 8 to 9 days. In certain days, more than 200 mm of rainfall occurs within 24 hours. 6.4. Limited period of torrential rainfall together with low-lying nature of the topography cause water logging during monsoon period. 7. Water Supply: 7.1. Surface Water: 7.1.1. Nearest source of water is Kutch Branch Canal at Jhajham, which is 10 km away from the identified site.

Page 271 of 297

7.1.2. It has been proposed that the Canal will provide water to the site from Patan which is located at chainage of 35 km (Charanka Distributary) along the Kutch Branch Canal.

7.2. Rainwater: 7.2.1. At the given site, rainfall is one of the major sources of water which is primarily used for cultivation. 7.2.2. At present, the rain water is harnessed by construction of temporary check dams. 7.3. Ground Water: 7.3.1. Ground water level ranges between 05 to 10 m. 7.3.2. During soil investigation, groundwater was encountered at a depth of 1.50 m depth. 7.3.3. Ground water in the region is very deep, however due to water logging in the monsoon season and due to hard pan below top soil, perched water table was observed, which is likely to fall below 10 m in summer. 7.3.4. Total dissolve salts of water ranges between 10,000 to 12,000 PPM which mostly depends upon intensity of rainfall. 7.3.5. Apparent Resistivity values of area show a variation below 5 Ohm, which indicates high level of ground water salinity at shallow depth. Due to the high degree of ground water salinity in the area, ground water structures have not been constructed by the farmers.
