MBD 9 CERTIFICATE OF INDEPENDENT PROPOSAL DETERMINATION

1 This Municipal Bidding Document (MBD) must form part of all proposals¹ invited.

2 Section 4 (1) (b) (iii) of the Competition Act No. 89 of 1998, as amended, prohibits an agreement

between, or concerted practice by, firms, or a decision by an association of firms, if it is between parties

in a horizontal relationship and if it involves collusive bidding (or bid rigging).² Collusive bidding is a pe

se prohibition meaning that it cannot be justified under any grounds.

3 Municipal Supply Regulation 38 (1) prescribes that a supply chain management policy must provide measures for the combating of abuse of the supply chain management system, and must enable the accounting officer, among others, to:

a. take all reasonable steps to prevent such abuse;

b. reject the proposal of any bidder if that bidder or any of its directors has abused the supply

chain management system of the municipality or municipal entity or has committed any improper conduct in relation to such system; and

c. cancel a contract awarded to a person if the person committed any corrupt or fraudulent act

during the bidding process or the execution of the contract.

4 This MBD serves as a certificate of declaration that would be used by institutions to ensure that,

when proposal are considered, reasonable steps are taken to prevent any form of bid-rigging.

5 In order to give effect to the above, the attached Certificate of Proposal Determination (MBD 9) must

be completed and submitted with the proposal:

¹ Includes price quotations, advertised competitive proposals, limited bids and proposals.

² Bid rigging (or collusive bidding) occurs when businesses, that would otherwise be expected to

compete, secretly conspire to raise prices or lower the quality of goods and / or services for purchasers

who wish to acquire goods and / or services through a bidding process. Bid rigging is, therefore, an

agreement between competitors not to compete.

³ Joint venture or Consortium means an association of persons for the purpose of combining their expertise, property, capital, efforts, skill and knowledge in an activity for the execution of a contract.

Page 11 of 11

1. The bidder has arrived at the accompanying proposal independently from, and without consultation,

communication, agreement or arrangement with any competitor. However communication between

partners in a joint venture or consortium³ will not be construed as collusive bidding.

2. In particular, without limiting the generality of paragraphs 6 above, there has been no consultation,

communication, agreement or arrangement with any competitor regarding:

(a) prices;

(b) geographical area where product or service will be rendered (market allocation)

(c) methods, factors or formulas used to calculate prices;

(d) the intention or decision to submit or not to submit, a proposal;

(e) the submission of a proposal which does not meet the specifications and conditions of

the proposal; or

(f) bidding with the intention not to win the proposal.

3. In addition, there have been no consultations, communications, agreements or arrangements with

any competitor regarding the quality, quantity, specifications and conditions or delivery particulars of

the products or services to which this proposal invitation relates.

4. The terms of the accompanying proposal have not been, and will not be, disclosed by the bidder,

directly or indirectly, to any competitor, prior to the date and time of the official bid opening or of the

awarding of the contract.

10. I am aware that, in addition and without prejudice to any other remedy provided to combat any

restrictive practices related to proposal and contracts, proposal that are suspicious will be reported

to the Competition Commission for investigation and possible imposition of administrative penalties

in terms of section 59 of the Competition Act No 89 of 1998 and or may be reported to the National

Prosecuting Authority (NPA) for criminal investigation and or may be restricted from conducting

business with the public sector for a period not exceeding ten (10) years in terms of the Prevention

and Combating of Corrupt Activities Act No 12 of 2004 or any other applicable legislation.

INTRODUCTION

City Power makes use of power and distribution transformers in the provision of electricity to its customers. Efficiency and reliability of transformers are critical in terms of meeting statutory Quality of Supply parameters as well as customer satisfaction and cost-effective network operation. Mineral insulating oil plays a crucial role in the performance of transformers, performing the functions of electrical insulation and heat dissipation. Due to the scarcity and cost of virgin (new) transformer oil and in line with City Power’s corporate responsibility in terms of environmental awareness and resource renewal, City Power will, where possible, give preference to used insulating oil that has been regenerated to the standard of SANS 555.

1 SCOPE

This specification defines City Power’s requirements for new and regenerated transformer oil in accordance with SANS 555.

2 NORMATIVE REFERENCES

The following documents contain provisions that, through reference in the text, constitute requirements of this specification. At the time of publication, the editions indicated were valid. All standards and specifications are subject to revision, and parties to agreements based on this specification are encouraged to investigate the possibility of applying the most recent editions of the documents listed below.

4 REQUIREMENTS

4.1 General

4.1.1 All virgin (new) oil shall comply fully with the requirements of SANS 555 and this specification, including the values indicated in the A&B Schedules. Reference to compliance with SANS 555 shall mean compliance with this specification where the requirements of this specification are more stringent than those of SANS 555.

4.1.2 The process of regeneration shall entail the removal of water, suspended particles, inorganic acid, deleterious matter, dissolved acids and chemical materials and gases, as well as the adjustment of the chemical and physical properties of the reclaimed oil to ensure compliance with SANS 555.

4.1.3 After regeneration, the oil shall match or exceed the requirements of SANS 555 and the values indicated in the A & B Schedules of this specification. Reference to compliance with SANS 555 shall mean compliance with this specification where the requirements of this specification are more onerous than those of SANS 555.

4.1.4 All new (unused) mineral insulating oil shall be polychlorinated biphenyl (PCB) free when tested in accordance with IEC 61619.

4.1.5 New mineral insulation oil for transformers shall be classified as uninhibited transformer oils (U), contain no antioxidant in accordance with IEC 60666.

4.1.7 The quantity of oil supplied or regenerated shall be determined (in litres) by calibrated flow meters.

4.1.8 The tenderer shall be fully responsible for the cleanup and rehabilitation of the site for all oil spillages emanating during the oil supply and/or regeneration process.

4.1.9 All new and regenerated oil shall bear the SANS 555 mark.

4.1.10 The oil may be required to be collected, regenerated and delivered in accordance with one or more of the following methods:

a) Collection in bulk, regeneration and supply in 210 litre drums;

b) Collection in bulk, regeneration and supply in bulk;

c) Circulation and regeneration of oil in transformer on site;

d) Circulation and regeneration of oil from tank to tank at Reuven Workshops; or

e) Supply of oil (in 210 litre drums) where the source oil is not supplied by City Power.

f) All oil supplied to City Power in drums shall be delivered in Class A drums. Any signs of rust on the drums shall be deemed unacceptable and such drums shall be returned to the supplier.

g) All old oil collected from City Power, in old or damaged drums, for disposal, shall be disposed of in their entireity by the successful tenderer – disposal includes old or damaged drums.
