 Annex
Guidelines for Tariff Based Competitive Bidding Process for Procurement of
Power From Grid Connected Wind Solar Hybrid Projects

1. BACKGROUND
1.1. It has been established that combining different sources of renewable energy reduces
their individual variability and gives better output. It also results in more efficient
utilization of transmission infrastructure and land resource. It is common knowledge
that wind is better during morning and evening or night, complementing solar energy
which peaks during day time. Hybrid projects backed by storage facility can further
enhance the quality of RE power.
1.2. MNRE issued Wind-Solar Hybrid Policy on 14.05.2018 (along with its
amendment on 11.10.2018) with the objective to provide a framework for
promotion of large grid connected wind-solar PV hybrid system for optimal and
efficient utilization of transmission infrastructure and land, reducing the
variability in renewable power generation and achieving better grid stability.
1.3. Subsequently, a scheme for setting-up of 2500 MW wind-solar hybrid power
projects was sanctioned on 25.05.2018 for procurement of hybrid power at a tariff
discovered through transparent process of bidding by Solar Energy Corporation
of India (SECI).
1.4. Section 63 of Electricity Act, 2003 promotes the competition in electricity sector
and provides for adoption of the tariff by the Appropriate Commission if the same
has been determined through transparent process of bidding in accordance with
the guidelines issued by the Central Government. The National Tariff Policy
notified on 28 January 2016 also encourages the procurement of renewable power
through competitive bidding to reduce the tariff.
1.5. These Guidelines will provide framework for transparent bidding process, as
required under Section 63 of the Electricity Act, 2003.

2. OBJECTIVES OF GUIDELINES

2.1. The objective of these Guidelines are as follows:

a) To provide a framework for procurement of electricity from wind solar hybrid
power project through a transparent process of bidding including standardization
of the process and defining of roles and responsibilities of various stakeholders.
b) To enable the Distribution Licensees to procure electricity from wind solar
hybrid power project at competitive rates in a cost effective manner.

3. APPLICABILITY OF GUIDELINES

3.1. These Guidelines are being issued under the provisions of Section 63 of the
Electricity Act, 2003 for long-term procurement of electricity through
 competitive bidding process, by the Procurer(s)’, from grid connected Wind Solar
Hybrid Power Projects (‘HPP’) having, (a) individual size of 5 MW and above at
one site with minimum bid capacity of 25 MW for intra-state projects; and (b)
individual size of 50 MW and above at one site with minimum bid capacity of 50
MW for inter-state projects, subject to the condition that the rated power capacity
of one resource is at least 25% of the rated power capacity of other resource.
Thus, for a 100 MW project to be treated as hybrid project, the minimum
resource (wind or solar) should not be less than 20 MW.
3.2. Storage may be added to the hybrid project
a) to reduce the variability of output power from wind solar hybrid project;
b) providing higher energy output for a given capacity (bid/ sanctioned
capacity) at delivery point, by installing additional capacity of wind and
solar power in a wind solar hybrid project required for charging of
storage facility; and
c) ensuring availability of firm power for a particular period.

In case of clause 3.2 (b) above, the additional capacity of wind and solar power
in the project shall be declared by HPG at the time of bid submission.
3.3. Unless explicitly specified in these Guidelines, the provisions of these Guidelines
shall be binding on the Procurer, Authorized Representative and Intermediary
Procurer. The process to be adopted in event of any deviation proposed from
these Guidelines is specified in Clause 23 of these Guidelines.

4. Explanation / Definition:

a) Procurer(s): The term ‘Procurer(s)’, as the context may require, shall mean the
distribution licensee(s), or their Authorized Representative, or an Intermediary
Procurer.

b) Authorized Representative of the Procurer(s): In cases, where the

distribution licensee(s), authorize any agency to carry out the tendering / bidding
process on its behalf then the agency will be responsible for fulfilling all the
obligations imposed on the ‘Procurer(s)’ during the bidding phase, in accordance
with these Guidelines.

c) Intermediary Procurer
(i) In some cases, an intermediary, between the distribution licensee(s) and the
wind solar hybrid Power Generator(s) (HPG) may be required either to aggregate
hybrid power to be purchased from different generators and sell it to the
distribution licensee(s). In such cases, the ‘Intermediary Procurer’ is essentially a
trader, buying power from the HPG(s) and selling the same to one or more
distribution licensees and shall carry out the bidding as per provisions of these
Guidelines.

(ii) The Intermediary Procurer shall enter into a Power Purchase Agreement (PPA)
with the HPG(s) and also enter into a Power Sale Agreement (PSA) with the

2
 distribution licensee(s). The PSA shall contain the relevant provisions of the PPA
on a back to back basis. The Intermediary Procurer may charge trading margin as
notified by the Appropriate Commission or in the absence of such notification as
mutually agreed with distribution licensee(s).

(iii) As long as the Intermediary Procurer has followed these Guidelines for
procurement of hybrid power, the distribution licensee(s) shall be deemed to have
followed these Guidelines for procurement of hybrid power.

5. APPROPRIATE COMMISSION

5.1. Subject to the provisions of the Electricity Act, 2003, Appropriate Commission
would be as under:
a) In case the hybrid power projects supplying power to Distribution licensee(s) of
one State, the Appropriate Commission, for the purpose of these bidding
Guidelines, shall be the State Electricity Regulatory Commission of the
concerned State where the distribution licensee(s) is located.
b) In case the hybrid power projects supplying power to Distribution licensee(s) of
more than one State, the Appropriate Commission, for the purpose of these
bidding Guidelines, shall be the Central Electricity Regulatory Commission.
c) For cases involving sale of hybrid power from generating companies owned or
controlled by Central Government, the Appropriate Commission shall be the
Central Electricity Regulatory Commission.

6. PREPARATION FOR INVITING BID AND PROJECT PREPAREDNESS

The Procurer shall meet the following conditions:
6.1. Bid Documentation:
a) Prepare the bid documents in accordance with these Guidelines and Standard
Bidding Documents (SBDs) [consisting of Model Request for Selection (RfS)
Document, Model Power Purchase Agreement (PPA) and Model Power Sale
Agreement (PSA)], notified by the Central Government, except as provided in
sub clause (c) below.
b) Inform the Appropriate Commission about the initiation of the bidding process.
c) Seek approval of the Appropriate Commission for deviations, if any, in the draft
RfS, draft PPA, draft PSA (if applicable) from these Guidelines and/ or SBDs,
in accordance with the process described in Clause 23 of these Guidelines.
d) However, till the time the SBDs are notified by the Central Government, for
purpose of clarity, if the Procurer while preparing the draft RfS, draft PPA,
draft PSA and other Project agreements provides detailed provisions that are
consistent with the Guidelines, such detailing will not be considered as
deviations from these Guidelines even though such details are not provided in
the Guidelines.
e) Further, in case of an ongoing bidding process, if the bids have already been
 submitted by bidders prior to the notification of these Guidelines and/or SBDs,
then if there are any deviations between these Guidelines and/or the SBDs and
the proposed RfS, PPA, PSA (if applicable), the RfS, PPA and the PSA shall
prevail.
f) The Procurer may disclose in the RfS, the prevailing incentives available to the
HPGs.

6.2. Site-related project preparatory activities including clearances:

In order to ensure timely commencement of supply of electricity, the bidder
would be required to submit documents in respect of matters as mentioned
below, as per the time schedule specified in the bidding documents:
a) Land acquisition: Identification of the 100% (hundred per cent) land at the
time of bid submission and submission of documents / Lease Agreement to
establish possession and right to use 100 % (hundred per cent) of the required
land in the name of the HPG for a period not less than the complete term of
PPA, on or before the Scheduled Commissioning Date (SCD). Wherever
leasing of private land is involved, the lease should allow transfer of land to the
lenders or Procurer, in case of default of the HPG.
b) No Objection Certificate (NOC)/ Environmental clearance (if applicable) for
the Project.
c) Forest Clearance (if applicable) for the land for the Project.
d) No objection certificate (NOC) from Ministry of Defence (if applicable).
e) A letter from State Transmission Utility (STU)/ Central Transmission Utility
(CTU), as applicable, confirming technical feasibility of connectivity of the
plant to STU/ CTU substation.
f) Any other clearances (if any), as may be legally required.

7. BID STRUCTURE
7.1. Bid Size: The bids shall be designed in terms of total hybrid power capacity to be
procured in MW. For intra- state projects a bidder shall be allowed to bid for a
minimum 25 MW wind solar hybrid power projects with at least 5 MW project at
one site and for inter-state projects a bidder shall be allowed to bid for a
minimum 50 MW wind solar hybrid power project at one site. The Procurer may
also choose to specify the maximum capacity that can be allotted to a single
bidder including its Affiliates. The maximum capacity for single bidder or
company or group of companies may be fixed by the Procurer keeping in mind
factors such as economies of scale, land availability, expected competition and
need for development of the market.
7.2. Bidding Parameters: For procurement of wind solar hybrid power, the tariff
quoted by the bidder shall be the bidding parameter. To enhance the quality of
power and to reduce variability of renewable power, procurer may define
additional parameters like minimum firm power output throughout the day or for
defined hours during the day, minimum electricity to be supplied per day, extent
of variability allowed in output power, etc. The Procurer may specify a ceiling

4
 tariff and in that case bidder has to quote tariff not more than that tariff. The
Procurer may select either of the following kinds of tariff based bidding: (a) fixed
tariff in Rs./kWh for 25 years or more or (b) escalating tariff in Rs./kWh with
pre-defined quantum of annual escalations fixed in Rs./kWh and number of years
from which such fixed escalation will be provided.

8. POWER PURCHASE AGREEMENT

The draft PPA proposed to be entered into with the successful bidder and draft
PSA (if applicable) shall be issued along with the RfS. Standard provisions to be
incorporated as part of the PPA shall include inter alia the following, which,
unless otherwise specified herein, shall be provided for on a back to back basis in
the PSA:
8.1. PPA Period: As the PPA period influences the tariff by determining the period
over which the investment is returned to the investor, longer PPA is favoured for
lower tariffs. The PPA period should thus be not less than 25 years from the date
of commissioning of the first part capacity of the Projects. The PPA may be
further extended on such term and conditions as mutually agreed between the
parties signing the PPA and approved by Appropriate Commission, provided the
arrangements with the land and infrastructure owning agencies, the relevant
transmission utilities and system operators permits operation of the Wind Power
Project beyond the initial PPA period of 25 years.
8.2. Capacity Utilization Factor (CUF):
8.2.1. The HPG will declare the annual CUF of its Project at the time of signing of
PPA and will be allowed to revise the same once within first three years of
COD. Calculation of CUF will be on yearly basis from 1st April of the year to
31st March of next year. The declared annual CUF shall in no case be less than
30 per cent. The variation permitted in hybrid power generation from the
declared CUF value will be indicated in the RfS. The lower limit will, however,
be relaxable to the extent of non-availability of grid for evacuation of hybrid
power, which is beyond the control of the HPG. For the first year of operation
of the project, the annual CUF shall be calculated for the complete year after
COD of the Project. Subsequently, the annual CUF will be calculated every year
from 1st April of the year to 31st March next year.
8.2.2. In case the project supplies energy less than the energy corresponding to the
minimum CUF, the HPG will be liable to pay to the Procurer, penalty for the
shortfall in availability of energy. This will, however be relaxable to the extent
of grid non-availability for evacuation, which is beyond the control of the HPG.
The amount of such penalty will be calculated @ 50% (fifty percent) of the PPA
tariff for the shortfall in energy terms, in accordance with the terms of the PPA.
Such penalty as recovered from the HPG shall be passed on by the Intermediary
Procurer to the End Procurer, as the case may be, after deducting losses of
Intermediary procurer.
8.2.3. In case of availability of power more than the declared annual CUF specified,
HPG will be free to sell it to any other entity provided first right of refusal will
vest with the Procurer(s). In case the Procurer purchases the excess generation,
the same may be done at the PPA tariff, and provision to this effect shall be
clearly indicated in the RfS document.
8.3. Repowering: The HPG will be free to re-power their wind capacity only during
the PPA duration. However, the Procurer will be obliged to buy power only as
per terms of PPA and any excess generation will be dealt as specified in clause
8.2 of these Guidelines.
8.4. Payment Security: The Procurer shall provide adequate payment security
measures, as specified below:
8.4.1. Scenario 1: Direct procurement by Distribution licensee from HPG:
The Distribution licensee shall provide payment security to the HPG through:
a) Revolving Letter of Credit (LC) of an amount not less than 1 (one) months’
average billing from the Project under consideration;
AND
b) Payment Security Fund, which shall be suitable to support payment for at
least 3 (three) months’ billing of all the Projects tied up with such fund;
c) In addition to a) & b) above, the Procurer may also choose to provide State
Government Guarantee, in a legally enforceable form, ensuring that there is
adequate security to the HPG, both in terms of payment of energy charges and
termination compensation, if any.
8.4.2. Scenario 2: Intermediary-Procurer procures from the HPG and sells to the
Distribution licensee:
a) Payment Security by Intermediary Procurer to the HPG: The Intermediary
Procurer shall provide payment security to the HPG through:
i. Revolving Letter of Credit (LC) of an amount not less than 1 (one)
months’ average billing from the Project under consideration;
AND
ii. Payment Security Fund, which shall be suitable to support payment of at
least 3 (three) months’ billing of all the Projects tied up with such fund.
b) Payment Security by Distribution licensee to Intermediary Procurer: The
Distribution licensee shall provide payment security to the Intermediary
Procurer through:
i. Revolving Letter of Credit (LC) of an amount not less than 1 (one)
months’ average billing from the Project(s) under consideration;
AND
ii. State Government Guarantee, in a legally enforceable form, such that
there is adequate security, both in terms of payment of energy charges and
termination compensation, if any. [for the purpose of this clause, the Tri-
Partite Agreement (TPA) signed between Reserve Bank of India, Central
Government and State Government shall qualify as State Government
Guarantee covering the security for payment of energy charges]. The
Intermediary Procurer shall ensure that upon invoking this guarantee, it
shall at once, pass on the same to the HPG, to the extent the payments to
the HPG in terms of the PPA are due.
In cases where End procurer is neither covered by Tri-Partite Agreement
6
 (TPA) nor is able to provide the State Government Guarantee as mandated,
intermediary procurers may charge extra trading margin based on risk
perception, from such Buying Utilities, in order to provide the requisite
payment security to the WPDs on behalf of the Buying Utility.
iii. In addition to i) & ii) above, the Distribution licensee may also choose to
provide Payment Security Fund, which shall be suitable to support
payment of at least 3 (three) months’ billing of all the Projects tied up with
such fund.
It is hereby clarified that the State Government guarantee shall be invoked
only after the Intermediary Procurer has been unable to recover its dues
under the PPA by means of the Letter of Credit and the Payment Security
Fund, if any.

8.4.3. The opening and maintenance of LC would be governed by relevant provisions/

guidelines notified by Ministry of Power and MNRE.
8.5. Change in Law / Regulations
8.5.1. In the event a change in Law/ Regulations results in any adverse financial loss/
gain to the HPG then, in order to ensure that the HPG is placed in the same
financial position as it would have been had it not been for the occurrence of the
change in Law, the HPG/ Procurer shall be entitled to compensation by the
other party, as the case may be, subject to the condition that the quantum and
mechanism of compensation payment shall be determined and shall be effective
from such date as may be decided by the Appropriate Commission.
8.5.2. In case change in Law / Regulations results in delay in commissioning, where
cause and effect between these two can be clearly established, the procurer may
provide suitable extension to commissioning of the project.
8.5.3. In these Guidelines, the term ‘Change in Law/ Regulation’ shall refer to the
occurrence of the following events, after the last date of the bid submission,
including (i) the enactment of any new law/ regulation; or (ii) an amendment,
modification or repeal of an existing law/ regulation; or (iii) the requirement to
obtain a new consent, permit or license; or (iv) any modification to the
prevailing conditions prescribed for obtaining a consent, permit or license, not
owing to any default of the HPG; or (v) any change in the rates of any taxes
which have a direct effect on the Project.
However, Change in Law shall not include any change in (a) taxes on corporate
income or any change in any withholding tax on income or dividends; and (b)
Custom duty on imported equipment.

8.6. Force Majeure

The PPA shall contain provisions with regard to force majeure definitions, exclusions,
applicability and available relief on account of force majeure, as per the industry
standards. The HPG shall intimate the Procurer about the occurrence of force majeure
within 15 (fifteen) days of the start of the force majeure and the Procurer shall take a
decision on his claim within 15 days of the receipt of the intimation.
 Government of India from time to time issues order for waiver of inter-state
transmission system (ISTS) charges and losses on transmission of wind power till a
certain date. In case the SCD of wind project is before the date till above ISTS waiver
is applicable, and if the commissioning of the project gets delayed beyond the
applicable date of ISTS waiver due to force majeure event, the liability of
transmission charges and losses would be shared between the HPG and procurer(s) in
ratio of 50:50. However, in case the commissioning of the project gets delayed
beyond the applicable date of ISTS waiver due to reasons attributable to the HPG the
liability of transmission charges and losses would be of HPG.

8.7. Generation Compensation for Off-take Constraints

The Procurer may be constrained not to off-take the power scheduled by HPG on
account of Grid unavailability or in the eventuality of a Back-down.
8.7.1. Generation Compensation in offtake constraints due to Grid
Unavailability:
During the operation of the plant, there can be some periods where the plant can
generate power but due to temporary transmission unavailability the power is
not evacuated, for reasons not attributable to the HPG. In such cases the
generation compensation shall be addressed by the Procurer in following
manner:

Duration of Provision for Generation Compensation

Grid
unavailability
Grid Generation Loss = [(Average Generation per hour during
unavailability in a the billing month) × (number of hours of grid
billing month as unavailability during that particular billing month)]
beyond 4 hours in
that particular Where, Average Generation per hour during the billing
billing month month (kWh) = Total generation in the billing month (kWh)
÷ (24 X number of days in that particular billing month)
hours less total hours of grid unavailability in that particular
billing month
The compensation calculated corresponding to the generation loss as above,
shall be provided by the Procurer at the PPA tariff, on a monthly basis.
8.7.2. Offtake constraints due to Back down: Governments encourages a status of
‘must-run’ to wind and solar power projects, as per Clause 5.2(u) of the Indian
Electricity Grid Code (IEGC). Therefore wind solar hybrid power plant, duly
commissioned, should never be directed to back down by a Discom/ Load
Dispatch Centre (LDC) except grid security or safety of any equipment or
personnel where it should be duly recorded, the justification of which can be
verified by any third party agency, and be notified in writing. No back-down /
curtailment to be ordered without giving formal/ written instruction for the
same. The details of back-down / curtailment, including justifications for such
curtailment, specifying data to back such curtailment, to be made public by the
concerned Load Dispatch Centre.

8
 In the event of any Backing down, the HPG shall be eligible for a Generation
Compensation, from the Procurer, in the manner detailed below.

Duration of Provision for Generation Compensation

Backdown
Hours of Generation Compensation = 100% x (Average Generation during
Backdown the month corresponding to the capacity backed down) x PPA
Tariff
during a
monthly Where, Average Generation during the month corresponding to
billing the capacity backed down (kWh) =
cycle. (CUF during the month ) x Σ (Backed down capacity in MW x
corresponding time of backdown in hours x 1000)

The Generation Compensation as calculated above will be limited to the extent

of shortfall in annual generation corresponding to the maximum CUF permitted
as per clause 8.2.1. The Generation Compensation is to be paid as part of the
energy bill for the successive month after receipt of Regional Energy Accounts
(REA). No trading margin shall be applicable on this Generation
Compensation.
Possible conditions for exclusion of Generation Compensation, on account of
Backdown purposes, shall be clearly specified in the RfS and the PPA.

8.8. Event of Default and the Consequences thereof

While detailed provisions with regard to the event of default of the concerned
parties and its resulting consequences shall be detailed in the SBDs, this clause
lays down the broad principles of contractually dealing with the default of the
HPG and the Procurers.
8.8.1. Generator Event of Default and the consequences thereof:
a) In the event the generator is unable to commission the plant within the
stipulated time period, or fails to supply power in terms of the PPA, or assigns
or novates any of its rights or obligations contrary to the terms of the PPA, or
repudiates the PPA, or effectuates a change in control or shareholding of its
promoters in breach of the provisions of the PPA, or commits any other acts or
omissions as laid down in the PPA and is also unable to cure any of the
aforesaid within the cure period, as may be provided in the PPA, the generator
shall be construed to be in default.
b) Upon being in default, the HPG shall be liable to pay to the Procurer, damages,
as provided in these Guidelines in Clause 17.3 for failure to commission within
stipulated time and Clause 8.2 for failure to supply power in terms of the PPA.
For other cases, pay to the Procurer, damages, equivalent to 6 (six) months, or
balance PPA period whichever is less, of charges for its contracted capacity.
The Procurer shall have the right to recover the said damages by way of
forfeiture of bank guarantee, if any, without prejudice to resorting to any other
legal course or remedy.
 c) In addition to the levy of damages as aforesaid, in the event of a default by the
HPG, the lenders shall be entitled to exercise their rights of substitution, in
accordance with the substitution agreement provided in the PPA and in
concurrence with the Procurer. However, in the event the lenders are unable to
substitute the defaulting generator within the stipulated period, the Procurer
may terminate the PPA and acquire the project assets for an amount equivalent
to 90% of the debt due, failing which, the lenders may exercise their mortgage
rights and liquidate the project assets.
8.8.2. Procurer Event of Default and the consequences thereof:
a) If the Procurer is in default on account of reasons including inter alia failure to pay
the monthly and/or supplementary bills within the stipulated time period or
repudiation of the PPA, the defaulting Procurer shall, subject to the prior consent of
the HPG, novate its part of the PPA to any third party, including its Affiliates within
the stipulated period.

b) In the event the aforesaid novation is not acceptable to the HPG, or if no offer of
novation is made by the defaulting Procurer within the stipulated period, then the
HPG may terminate the PPA and at its discretion require the defaulting Procurer to
either (i) takeover the Project assets by making a payment of the termination
compensation equivalent to the amount of the debt due and the 110% (one hundred
and ten per cent) of the adjusted equity as defined below, less Insurance Cover if
any or, (ii) pay to the HPG, damages, equivalent to 6 (six) months, or balance PPA
period whichever is less, of charges for its contracted capacity, with the Project
assets being retained by the HPG.

c) In the event of termination of PPA, any damages or charges payable to the STU/
CTU, for the connectivity of the plant, shall be borne by the Procurer.

d) Adjusted Equity means the Equity funded in Indian Rupees and adjusted on the
first day of the current month (the “Reference Date”), in the manner set forth below,
to reflect the change in its value on account of depreciation and variations in
Wholesale Price Index (WPI), and for any Reference Date occurring between the
first day of the month of Appointed Date and the Reference Date;
i. On or before COD, the Adjusted Equity shall be a sum equal to the Equity
funded in Indian Rupees and expended on the Project, revised to the extent of
one half of the variation in WPI occurring between the first day of the month of
Appointed Date and Reference Date;
ii. An amount equal to the Adjusted Equity as on COD shall be deemed to be the
base (the “Base Adjusted Equity”).
iii. After COD, the Adjusted Equity hereunder shall be a sum equal to the Base
Adjusted Equity, reduced by 0.333% (zero point three three three percent)
thereof at the commencement of each month following the COD [reduction of
1% (one percent) per quarter of an year] and the amount so arrived at shall be
revised to the extent of variation in WPI occurring between the COD and the
Reference Date;

For the avoidance of doubt, the Adjusted Equity shall, in the event of
termination, be computed as on the Reference Date immediately preceding the
Transfer Date; provided that no reduction in the Adjusted Equity shall be made
10
 for a period equal to the duration, if any, for which the PPA period is extended,
but the revision on account of WPI shall continue to be made.

e) Debt Due means the aggregate of the following sums expressed in Indian Rupees
outstanding on the Transfer Date:

i. The principal amount of the debt provided by the Senior Lenders under the
Financing Agreements for financing the Total Project Cost (the ‘Principal’) but
excluding any part of the principal that had fallen due for repayment 2 (two)
years prior to the Transfer Date;
ii. All accrued interest, financing fees and charges payable under the Financing
Agreements on, or in respect of, the debt referred to in sub-clause (i) above until
the Transfer Date but excluding (i) any interest, fees or charges that had fallen
due one year prior to the Transfer Date, (ii) any penal interest or charges payable
under the Financing Agreements to any Senior Lender (iii) any pre-payment
charges in relation to accelerated repayment of debt except where such charges
have arisen due to Utility Default, and (iv) any Subordinated Debt which is
included in the Financial Package and disbursed by lenders for financing the
Total Project Cost.

Provided that if all or any part of the Debt Due is convertible into Equity at the
option of Senior Lenders and/or the Concessionaire, it shall for the purposes of
this Agreement be deemed not to be Debt Due even if no such conversion has
taken place and the principal thereof shall be dealt with as if such conversion
had been undertaken.

Provided further that the Debt Due, on or after COD, shall in no case exceed
80% (eighty percent) of the Total Project Cost.

9. BIDDING PROCESS
9.1. The Procurer shall call for the bids adopting a single stage two envelop bidding
process to be conducted through Electronic mode (e-bidding). The procurer may
also opt for e-reverse auction for final selection of bidders, in such a case, this
will be specifically mentioned in the notice inviting bids and bid document. E-
procurement platforms with a successful track record and with adequate safety,
security and confidentiality features will be used.

HPP(s) in terms of these Guidelines.
9.3. The bidding documents including the RfS, draft PPA and draft PSA (if
applicable) shall be prepared by the Procurer in consonance with these Guidelines
and the SBDs.
9.4. The Procurer shall publish the RfS notice in at least two national newspapers and
its own website to accord wide publicity.
9.5. The Procurer shall provide opportunity for pre-bid conference to the prospective
bidders, and shall provide written interpretation of the bid documents to any
bidder which shall also be made available to all other bidders. All the concerned
 parties shall rely solely on the written communication. Any clarification or
revision to the bidding documents shall be uploaded on the website of the
Procurer for adequate information. In the event of the issuance of any revision or
amendment of the bidding documents, the bidders shall be provided a period of at
least 7 (seven) days therefrom, for submission of bids.
10. RfS DOCUMENT
The standard provisions to be provided by the Procurer in the RfS shall include
