1. Background

The Government of India launched the Jawaharlal Nehru National Solar Mission to promote ecologically

sustainable growth while addressing India’s energy security challenges. NTPC Vidyut Vyapar Nigam Ltd (NVVN)

is responsible for the implementation of first phase of the mission. Under this scheme NVVN allotted capacity to

Independent Power Producers (IPPs) on the basis of reverse bidding of tariff and also signed a PPA with the

IPPs. Therefore Alex Solar Private Limited (ASPL), in order to derive benefit of the policy, intends to set up a 5

MW Solar Power Project in Orissa by procuring EPC contractor through ICB route.

The Jawaharlal Nehru National Solar Mission is a major initiative of the Government of India to

promote ecologically sustainable growth while addressing India’s energy security challenges. The

immediate aim of the Mission is to focus on setting up an enabling environment for solar technology

penetration in the country both at a centralized and decentralized level. The first phase of this

Mission aims to commission 1000 MW of grid-connected solar power projects by 2013. NTPC Vidyut

Vyapar Nigam Ltd (NVVN), a subsidiary of National Thermal Power Corporation, is the designated

nodal agency responsible for implementation of Phase-I of mission. NVVN selected the Independent

Power Producers (IPPs) on the basis of reverse bidding process and signed a power purchase

agreement with the selected developers.

In this context Alex Solar Private Limited (ASPL) proposes to set up a 5 MW Solar PV power plant in

the state of Orissa and intends to initiate an International Competitive Bid (ICB) process to select

Engineering, Procurement and Construction (EPC) contractor to execute the proposed project.

� Stage-1: Issuance of ‘Notice Inviting Tender (NIT)’ and evaluation of the ‘Expression of

Interests (EOI)’ to validate whether the bidders meet the qualification criteria or not.

� Stage-2: Issuance of ‘Request for Proposal (RFP)’ document to the bidders qualified under

stage 1.

� Stage-3: Evaluation of the bids received and recommending the outcome to enable ASPL to

finalize the appointment of the EPC contractor.

1.2.1 Stage-1

The NIT for the project was published in the Economic Times on 16th

June 2011. The NIT published is

attached with this report as Annexure-1.

The NIT contained brief scope of work regarding the proposed project, the pre-qualification

requirements and the timelines for the submission of the EOI from the bidders and the issuance of

the RFP document. The last date for submission of EOI was 22nd

Further Indure Montealto submitted the very few of the required details (as mentioned in the table

above) on 20th

August, 2011. An assessment of the submitted documents has been provided in the

subsequent paragraphs:


bidder covers the following topics- the technical selection, system description, system

configuration for various components (crystalline module & module mounting structures,

inverters, SCADA system, IT system comprising hardware and software), fire alarm & fire

suppression system and control room & inverter cooling system. However the technical

evaluation committee found a lot of calculation mistakes, data inconsistency.

� The correct mounting structure and plant layout was also missing in the data submitted

along with the proposal.

� The rated power tolerance was also provided as +/- 5% whereas required tolerance has

to be +/- 3%.

� Deviation in inverter selection. In data sheet table-21, 500 kW inverter has been

mentioned, whereas in bid document it is 1000kW.

� The bidder is not able to guarantee the commissioning of project on or before 30th

November, 2011.

� BOQ for solar power plant has not been provided by the bidder which is must for

technical evaluation.


[21]

� Technical write-up giving complete design, specifications and information of mounting

structures, material used, fabrication process, treatments performed, standards

followed, types of bolts used, etc. have not been submitted.

� General arrangement drawing of mounting structures, foundation plans, anchoring

plans, overall dimensions, installation plans, structural plans and elevation and framing

details have not been submitted.

� IEC Certificates of First Solar Module have not been submitted which is a must for

realistic.


equipment, along with the technical specification and the bill of material for spares, are not

mentioned in the proposal.

� Scope of work mentioned in the proposal has been considered with certain deviations,

exclusions and assumptions which doesn’t comply to the RFP requirements

2.2.3.4 Conclusion

Based on the above analysis it is concluded that though the proposal submitted by Indure –

Montealto Consortium is responsive but the proposal doesn’t meet the prescribed technical

specifications (as per the RFP) due to missing data and calculation errors. Also it seems that the

bidder has proposed for certain deviations, exclusions and assumptions which doesn’t comply with

RFP requirement. Thus, the bidder, Indure – Montealto Consortium is technically disqualified.

2.3 Summary of evaluation

The Techno-Commercial proposals submitted by the aforesaid 3 bidders have been examined. Based

on examination it is concluded that only Moser Baer Engineering and Constructions Ltd (MBECL) and

Abir Infrastructure Private Limited (AIPL) are capable in meeting the specified quantity and quality

requirements while complying with the applicable laws as well as the requirements of the project as

mentioned in the RFP document.


[22]

The strategies proposed by MBECL and AIPL have been studied and it is found that both MBECL and

AIPL are aware of the technical challenges inherent in the projects. The adequacy of proposed

experience and capability to execute the project is assessed as satisfactory.

The table below summarizes the status of evaluation of techno commercial proposal submitted by

the bidders for the reasons explained in the previous section:

Table 11: Summary of Evaluation

Project Name MBECL AIPL Indure - Montealto

Alex Solar Private Limited Qualified Qualified Dis - qualified


Thus, MBECL and AIPL are found to be technically qualified for executing the 5 MW Solar Power

Project. As such its price bid may now be opened.

3. Financial Bid Opening

As part of second stage of the biding process the disqualified bidders were intimated via email dated

24th

August, 2011. Further qualified bidders were also intimated about financial bid opening details.

The financial bid of successful bidder was opened on 25th

August, 2011 at 4.30 pm at CRISIL’s office

i.e. in front of officials of successful bidder.

In response to the RFP the following financial quotes were received:

Table 12: Financial Quote for the Project

Sr. No. Project Name Bidder Financial Quote (INR)

1. Alex Solar Private Ltd MBECL 67,76,17,750

2. Alex Solar Private Ltd AIPL 71,14,98,638

3.1 Concluding Remarks

Based upon the outcomes of technical and financial bids and the way entire process has been

managed, it is concluded that the bid process was conducted in a transparent manner. Since the

price quoted by Moser Baer Engineering & Constructions Ltd was the lowest and is therefore

considered the L1 bidder.

In view of the above, the project owner may initiate action as found appropriate.
