Method of A&B schedule response
Tenderers are required to submit responses to all A&B schedule items. Responses may not be altered after
tender closure, and missing answers may not be provided after tender closure.
Responses to A&B schedules shall be based on the requirement of Schedule A. “Comply” shall only be
acceptable in response to a Schedule A requirement stating “Comply”. Other items requiring a word,
sentence or number response shall be responded with reference to with the actual capability of the
equipment offered.
In cases where a product does not comply with a Schedule A requirement, the Tenderer shall respond
indicating the product’s existing capability. Where a product is to undergo development so as to meet the
requirement, the Tenderer may append the words “Comply with Development” or “CWD” to this response.
All items marked “CWD” shall be described in a letter of undertaking by the OEM that the said development
work will be undertaken by them, completed within the first month of awarding of a product development
contract with the Tenderer.
Certain responses to A&B schedule items require verification by Eskom. Tenderers shall provide evidence
for this verification in one of two ways, as indicated against applicable A&B schedule items:
1)
Tender response verified during product demonstration. These items will be verified during the
product demonstration. These will be demonstrated by the Tenderer by way of the DFR interface
software/manual for the specific DFR model tendered. The evidence of compliance need not be
included in the tender submission.
2)
Tenderer response verified from supporting documentation. The Tenderer shall submit a
reference, including file name and page number from within the tender pack as to where evidence
of the response is to be found. Eskom is not permitted to accept additional information after the
tender closing date and items with incorrect or missing references will be assigned a score of “Noncompliant”.
References shall be made to the file name of the electronic copy of the supporting document, and
the page number within that file (not necessarily the same as the page numbers printed on each
page of the manual).
The Tenderer may present the OEM’s letter of undertaking of development described above as evidence of
compliance to items with “CWD” responses. The letter of undertaking shall be included with the tender
response. The Tenderer shall, nevertheless, also provide evidence of the product’s existing capability (if
any).

Tender evaluation (Technical)
This section details the methodology to be employed by Eskom in scoring the “Technical” category of the
tender evaluation.
Each tender shall pass all Technical Gatekeeper criteria as listed in Annex A.1. Tenders not meeting any of
the Technical Gatekeepers shall be immediately excluded from further evaluation, and shall be assigned a
Technical score of 0%.
Tenders which pass the Technical Gatekeepers shall be adjudicated a score out of 100%, made up of
scoring in three sub-categories:
Technical sub-category 1: Product A&B Schedules (Weight = 50%).
Technical sub-category 2: Product Demonstration (Weight = 30%).
Technical sub-category 3: Product Risk and Support (Weight = 20%).
The detailed methodologies for scoring in each sub-category are provided in Sections 8.1 to 8.3 below.
8.1
Sub-category 1: Product A&B Schedules
This section shall comprise scoring of the technical schedules of the DFR scheme. Not all items will be
scored so as to maintain the focus of the evaluation on critical functionality. Compliance with non-scored
items and major deviations to scored items shall be addressed in Sub-category 3: Product Risk and Support.
8.1.1
Verification
Verification of A&B schedule responses by Tenderers shall be conducted in the following ways, as indicated
in the A&B schedules:
1)
[Default option] Tenderer response taken at face value. These items, typically less critical
functionality, will not be verified by Eskom during the tender evaluation. Compliance will be verified
during a product development contract arising from this enquiry.
2)
Tender response verified during product demonstration. These items will be verified during the
product demonstration. These typically entail confirmation of the type and number of functions
available in the DFR and their setting ranges. These will be demonstrated by the Tenderer by way
of the DFR interface software and/or product manuals for the specific device model tendered.
3)
Tenderer response verified from supporting documentation.
technical team at the Eskom tender evaluation facility.
8.1.2
Scoring
This will be done by the Eskom
Each item will be assigned a score by the Eskom evaluation team based upon the tendered response

Tender responses claiming compliance to an item (e.g. “Comply”) but which are found to be partially or noncompliant during verification will be assigned the corresponding lower score by the Eskom evaluation team.
Items for which compliance is not claimed (e.g. “Do Not Comply” or no response), but which are found to be
compliant during verification will be scored as partially or non-compliant based on the original response.
Eskom reserves the right to adjudicate whether items which are not “Fully Compliant” or “Compliant with
Development” are to be scored “Partially compliant” or “Non-compliant” irrespective of any claim made by the
Tenderer in this regard.
Items will only be accepted as “Compliant with Development” if accompanied by the letter of undertaking
from the OEM described in Section 7.2. These items will achieve full score on the A&B schedule evaluation
but may be penalised in the “Product Risk and Support” category.
A&B schedule items for which no answer is provided shall automatically be scored as “Non-compliant”.
The A&B Schedules use a default weight of 1 for each scored item. Critical items are assigned higher
weights. For example, a weight of 3 indicates that the item will count the same as three items with weight 1.
A&B schedules shall be scored independently by at least two Eskom Subject Matter Experts (SMEs). The
SMEs will then collaborate to derive a consensus score.
The score for each item will be multiplied by its weight to obtain the total score per item. All scores for the
A&B Schedule will be tallied and a percentage shall be calculated based on the maximum possible score.
This will be recorded as the percentage score for that product.
8.2
Sub-category 2: Product demonstration
This section shall be scored by the technical evaluation team following a two day visit to each Tenderer’s
local offices. Tenderer visits shall be conducted during the tender evaluation phase. The visits to tenderers
passing the gatekeeper criteria shall commence soonest after the successful completion of the desktop
evaluations. Suppliers shall be advised of their qualification for the visit, and on the exact date of the visit at
least two weeks before the commencement thereof.
8.2.1
Overview
The demonstration shall comprise three parts:
1)
IEC61850 demonstration (60%)
2)
Upgradeability demonstration (40%)
3)
A&B schedule verification (scored in Sub-category 1). Tenderer representatives will provide
evidence for A&B schedule items designated for verification via demonstration.
The demonstration shall commence at 09h00 each day and end latest 17h00 each day. The Tenderer shall
be responsible for time keeping to ensure that the full scope of all parts of the demonstration is achieved
within the allotted time.
The full scope of the product demonstrations are described in [2-PD] “Product Demonstration.xls”. Eskom
will score Tenderers only on the items described. Tenderers may provide Eskom with additional information,
but this shall not be scored and may unnecessarily consume the Tenderer’s allotted demonstration time.
Eskom will only award Tenderers points to a product demonstration item if the item has been demonstrated
in its entirety using the test system in the presence of the Eskom team. Promises of future functionality or
functionality under development will not count towards the product demonstration.
8.2.2
IEC61850 demonstration
This comprises a task to be completed and submitted as part of the tender response and the following

Upgradeability demonstration
This part of the product demonstration shall involve Tenderers demonstrating to the evaluation team the
upgradeability of a tendered DFR with hardwired binary inputs and outputs (i.e. for use in legacy substations)
to a DFR that can be used at ‘IEC61850-ready’ substations.
Tenderers offering Option A and Option B as a solution to this enquiry shall demonstrate that an Option B
DFR (i.e. where binary input/output signals are hardwired to/from the DFR) can be upgraded for use in a
IEC61850-ready substation (i.e. where binary input signals are received as GOOSE and binary output
signals can be broadcasted/published as MMS messages).
Tenderers offering Option C DFRs shall demonstrate that a DFR that is used in a legacy substation (i.e.
where binary input/output signals are hardwired to/from the DFR) can be re-configured for use in a
IEC61850-ready substation (i.e. where binary input signals are received as GOOSE and binary output
signals can be broadcasted/published as MMS messages).
Tenderers shall demonstrate this as follows:
1) The tenderer shall generate binary output signals from an Eskom supplied protection IED (i.e. by
injecting voltage/current signals from a test set into the IED and causing it to operate). The tenderer
shall then demonstrate that the tendered Option B or Option C DFR is triggered via hardwired binary
inputs from the protection IED and show the associated fault record(s).
2) The tenderer shall then perform the necessary re-configuration and/or hardware/firmware upgrades
on the same DFR and demonstrate the triggering of the DFR via GOOSE signals generated from the
Eskom supplied protection IED and show the associated fault record(s).
8.3
Sub-category 3: product Risk and Support
Eskom SMEs, as part of the A&B schedule evaluation, shall compile a narrative summarising risks
associated with the products such as: unproven technology, technology requiring development, major nonconformances to the standards/specification, and excessive or re-occurring minor non-conformances. This
narrative will also be based on the responses to questions in Annex A.2 of this document and Annex B of [3].
This narrative shall be used to assign a product risk score in the scale:
100%
-
Low risk
80%
-
Acceptable risk
40%
-
High risk
0%
-
Very high risk

Price schedules and projected quantities
The tender pack includes a PS5 schedule which details all items to be tendered upon in this enquiry. This
information is the definitive list of items to be supplied and supersedes the price schedule included in the
detailed DFR product specification.
The price schedules differentiate between items for the development (D1) and production (P1) phase
contracts.
The following sections provide clarity on the price schedule items and supersede any requirements listed
elsewhere amongst the technical documentation. Eskom’s projection of required quantities over the four
year production contract is described in Section 9.7.
9.1
Options A, B and C
In section 3.1 of [3], three different options (i.e. option A, B and C) of DFRs are listed. As mentioned in that
document, Eskom will require DFRs in both its legacy and ‘IEC61850-ready’ substations.
