Summary
ESKOM duvha power station requires a five-year maintenance and service contract for diesel compressors, covering both mobile and station units. The contract is awarded under the 90/10 preference point system, with price weighted at 90 points and b-bbee specific goals at 10 points. Bidders must commit to a mandatory CIDB skills development goal of 0.25% For mechanical engineering works, a 100% local procurement content target, and subcontracting at least 6% of contract value to designated groups. The most consequential consideration is that failure to meet the mandatory CIDB csdg percentage renders the tender non-responsive.
Key Requirements
Closing date: 24 November 2026 at 08:00. Submission method and address are not stated in the document.
Mandatory CIDB skills development: Bidders must commit to a CSDG percentage of 0.25% for Mechanical Engineering Works. Failure to meet this mandatory percentage renders the tender non-responsive.
B-BBEE specific goals (90/10 system): Level 1 = 10 points, Level 2 = 9, Level 3 = 6, Level 4 = 5, Level 5 = 4, Level 6 = 3, Level 7 = 2, Level 8 = 1, Non-compliant = 0. A valid B-BBEE certificate or sworn affidavit is a condition for contract award.
B-BBEE improvement plan: Must be submitted within 30 days of contract signature. Level 4 bidders must achieve Level 3 by end of first year; Level 5-8 or non-compliant bidders must achieve Level 4 by end of first year, then improve one level each year.
Subcontracting: Minimum 6% of contract value must be subcontracted to an EME or QSE that is 51% black-owned in rural/underdeveloped areas or townships. Mandatory returnables include signed subcontracting agreements or letters of intent with subcontractor registration and B-BBEE documents.
Local procurement content: Target is 100%. Tender response must be separated into local and imported components as per the Price Schedule.
SDL&I penalties and retention: Eskom will apply a penalty of 1.5% of the invoice amount or contract value for failure to meet SDL&I obligations, and will retain 1.5% of every invoice (excluding VAT) as security for the contract duration.
Document read. The full tender notice and its supporting documents are read end-to-end. Key sections, requirements, dates, and contact details are identified and pulled into a working summary you can act on.
Compliance review. The working summary is checked against South African procurement standards — PFMA, PPPFA, B-BBEE, CIDB, local content, and preferential procurement — so nothing critical is missed before you start your bid response.

Risk bands
Low risk: the scope does not touch Eskom's core business processes (examples given: cleaning, security, landscaping).
High risk: the scope directly affects core business processes (examples given: transformers, cables, conveyor belts).
Resulting categories
Category 1 — high risk, high value: only ISO 9001 certified bidders may participate; no award without a valid certificate. Typical of contracts involving manufacturing.
Category 2 — low risk, high value: ISO 9001 is not mandatory where the scope does not call for it.
Category 3 — high risk, low value: a documented quality management system must be in place.
Any transaction involving installation, manufacturing, testing or commissioning requires a Quality Control Plan (QCP) or Inspection and Test Plan (ITP), whatever the category.
Exemption Certificate, 240-144723833, where quality requirements are waived.

Open tenders are advertised on the Eskom Tender Bulletin and the National Treasury e-Tender Portal; closed tenders are issued directly to identified bidders.
Addenda are published on the same platforms as the original invitation and form part of the tender documents.
All communication is in writing, in English, and only with the Eskom Representative; Eskom accepts no responsibility for communications a bidder does not receive.
Bidders must check the tender documents on receipt and report any discrepancy or missing document to the Eskom Representative.
Date and time: 24 November 2026 at 10:00 (South African Standard Time, GMT+2).
The tender office clock is set to the Telkom time signal and that time is strictly applied.
Site visit or clarification meeting
A site visit and/or clarification meeting may be stipulated as compulsory in the Tender Data; the date, time and venue are given there.
Attendance at a compulsory event is required — non-attendance disqualifies the bid.
Clarification requests
Written queries go only to the Eskom Representative and must allow Eskom reasonable time to respond and bidders time to adjust before closing.
Responses and any addenda are published on the Eskom Tender Bulletin and the National Treasury e-Tender Portal; bidders must monitor both platforms for changes to the closing date and for amendments.
Paper: one complete original plus one complete hard copy of the original, each in a separate package marked "ORIGINAL" and "COPY", sealed together in an outer package marked "Confidential".
E-tendering: upload and finalise through the Eskom Tender Bulletin e-tendering page, filing documents under the Technical, Commercial and Financial folders.
Email submission is not accepted unless the Tender Data states otherwise.
Tenders must be in English; handwritten entries must be in ink, not pencil.
Each package must show the Eskom submission address, the tender number, the bidder's name, physical address, email address and the telephone number of the authorised signatory.
Deadlines and late bids
Late tenders are not accepted; proof of posting or courier dispatch is not proof of delivery.
The e-tendering system closes at the stated time and will not permit changes or finalisation afterwards.
Eskom accepts no responsibility for courier or postal delays, network problems on the bidder's side, or tenders delivered to the wrong location.
Eskom staff may not place a tender in the tender box on a bidder's behalf.
Returnables
Acknowledgement Form: confirms receipt of the tender pack and states whether the bid covers the whole or part of the scope.
Mandatory tender returnables: must be complete and submitted by the closing time; missing items disqualify the bid.
Proof of authority to act as agent, where an agent bids for a principal.
SDL&I Undertaking: required by contract award; failure to submit excludes the bid from award.
Designated material and threshold information: required by contract award.
Pricing Schedule, including a line item for cataloguing where cataloguing applies.
SHEQ proof of systems, policies and capability.
B-BBEE certificate, CSD number or CSD report where B-BBEE is a pre-qualification criterion.

Disqualification risks
Original or copy not submitted in paper form, or copies supplied after closing.
Mandatory returnable omitted or incomplete at closing.
Tender not signed by a duly authorised signatory.
Corrections made with correction fluid or tape, or alterations not initialled by all signatories.
Failure to attend a compulsory site visit or clarification meeting.
Basic compliance check — a bid failing the basic compliance requirements is non-responsive.
Mandatory returnables — any stipulated document missing at closing disqualifies the bid.
Pre-qualification criteria, where stipulated. Eskom will not assess the same criterion twice across phases.
Functionality, where applied — bidders are scored and must meet the minimum threshold set in the Tender Data to proceed.
Financial analysis — Eskom assesses the financial risk of contracting with the bidder; where mitigating factors are absent, insufficient, or the risk is too high, or the bidder rejects the mitigating measures, the bid is not considered for award.
Price evaluation — factors such as CPA, forex, commodity exposure, unconditional discounts, technical adjustment, present value and forecast invoicing rates inform the evaluation price.
B-BBEE scoring — the level on the CSD report, certificate or affidavit is scored.
Specific goals scoring — supported by documentation submitted with the bid.
Preference points
Bids are ranked by adding price and specific-goal scores, under the 80/20 or 90/10 system as applicable.
A bidder who fails to meet specific goals, or omits the supporting proof by closing, is not disqualified but scores zero for specific goals.
Where B-BBEE is not a pre-qualification criterion, a missing, expired or fraudulent certificate or affidavit scores zero PPPFA points rather than disqualifying the bid.
Other
Eskom may award on objective criteria under section 2(1)(f) of the PPPFA where these are stated in the tender; functionality and B-BBEE scorecard elements may not be used as objective criteria.
A reverse e-auction may be used, in which case bidders submit a complete tender without prices and any prices included are disregarded.
Arithmetic errors: amounts in words prevail over figures; the highest-ranked bids are checked for decimal-point errors, omitted pricing schedule or bill-of-quantities entries, multiplication and addition errors, and incorrect or under-precise exchange rates. A bidder who refuses the corrected prices is rejected.
Five-year maintenance and service contract for diesel compressors, covering both mobile and stationary units, at Duvha Power Station, Mpumalanga.

Contract Skills Development Goals apply to contracts of 12 months or more where the value is R5 million or more (professional service or service contracts) or the CIDB grade is 7 or higher (engineering and construction works, or design and build).
Contract Participation Goals for engaging targeted enterprises apply to General Building and Civil Engineering works contracts of at least six months where at least 25% of the main contract can reasonably be subcontracted in the CE, EB, GB or ME classes.
Communication
All communication goes to and from the Eskom Representative only, in writing and in English; contact with any other Eskom official is not permitted.

Bidders may not alter or add to the tender documents except on Eskom's instruction or to correct their own errors; all alterations must be initialled by every signatory, and correction fluid or tape may not be used.
Eskom may seek clarification and documents during evaluation, but mandatory returnables due at closing will not be requested afterwards; a price breakdown may not change prices or the substance of the bid, except to correct arithmetic errors.
Arithmetic checks: words prevail over figures; line-item totals prevail over unit rates where a multiplication error exists; the quoted line total prevails where a decimal point is misplaced; the total of prices prevails where addition errors exist, with item prices revised to match.
A bidder who does not accept the corrected prices is rejected.
Rates and prices must include all duties, taxes (including VAT) and levies applicable 14 days before the closing date and time.
Prices are fixed for the contract duration and are not subject to adjustment except as the tender allows.
Prices must be stated in South African Rand unless the tender instructs otherwise; where part payment in another currency is permitted, the exchange rate and base date are as stipulated in the tender.

Security and insurance
Where performance security is required, the bidder must name at least two financial institutions it may approach; Eskom may reject an unsuitable institution.
Insurance provided by Eskom may not cover the full extent required under the conditions of contract; bidders should obtain their own advice.
Financial standing
Eskom assesses the financial risk of contracting with the bidder from its financial statements and may impose mitigating requirements; a bidder that does not agree to them is not considered for award.
Costs
Bidders carry all costs of preparing and submitting a tender, including any testing needed to show compliance with the evaluation criteria and any contract negotiation.
The bidder, including any joint venture or consortium member, must meet the eligibility criteria in the Tender Data and must not be restricted from doing business with Eskom or any State-Owned Company.
Subcontracting 100% of the scope is not permitted and renders the bid ineligible.
Statutory and registration requirements
CSD registration, with the B-BBEE level as reflected on the CSD report.
B-BBEE: where the level is a pre-qualification criterion, a certificate, CSD number or CSD report must be submitted by closing or the bid is disqualified; fraudulent, expired or disputed proof also disqualifies. Where subcontracting to designated groups is a pre-qualification criterion, the subcontractor's B-BBEE status and CSD number or certificate must be submitted by closing.
CIDB: where a grade is stipulated, registration is mandatory at closing; proof of application may be accepted at closing with the CIDB database printout due by contract award.
Tax and other statutory compliance as required by National Treasury instructions, PPPFA regulations, the amended B-BBEE Codes, COIDA and the OHS Act.
Local content: materials designated by the dtic for local production and content must be reported, with the information due by contract award.
SHEQ: proof of safety, health, environment and quality systems, policies and capability must be in place at closing and/or contract award, with all related costs and personnel reflected in the tender.
Integrity
Misrepresentation or falsification of any information, certificate, affidavit or document may lead to disqualification, referral of B-BBEE fraud or fronting to the B-BBEE Commission, suspension from business with State-Owned Companies for up to 10 years, and imprisonment.

Compliance is also required with National Treasury instruction notes, CIDB regulations for construction work, dtic local content designations, PPPFA regulations and the amended B-BBEE Codes.
Tender validity: bids must remain open for acceptance for the validity period after closing; Eskom may request an extension, and a bidder who declines is excluded from further consideration. A bidder who extends may not change its tender.
If validity expires before contracts are concluded, the procurement is treated as concluded without an award.
Eskom may accept or reject any variation, deviation or alternative tender, and may accept the whole or any part of a tender.
Eskom may cancel the tender before contract conclusion and will give written reasons on request; it may then abandon the requirement or re-issue the invitation.
Eskom, its subsidiaries, shareholders, advisers, directors, employees and representatives are not liable for losses or claims arising from a bidder's participation in the process, or from its amendment, suspension or termination.
Eskom may enter mandated negotiations with one or more selected bidders under its procurement policies.
Eskom gives no warranty on the accuracy or completeness of information in the tender documents and disclaims liability for it.
Bidders must treat procurement matters as confidential and use Eskom's documents only to prepare and submit a tender.
The successful bidder must check the draft contract and sign the contract documents, with authorised signatories completing the original and one copy of the Form of Agreement.
Contract documents are revised to reflect addenda, the returnables, and changes agreed in negotiation.
The contractor must meet the Contract Skills Development Goals and Contract Participation Goals where these apply.
Basic compliance is assessed before detailed evaluation; failure makes the bid non-responsive.
Mandatory returnables missing at closing disqualify the bid.
Pre-qualification criteria apply where stipulated, and no criterion is measured twice across phases.
Functionality is scored where applied, against a minimum threshold set in the Tender Data.
Financial risk analysis may exclude a bidder where risk is too high or mitigating measures are refused.
Price is evaluated using the criteria in the Tender Data, taking account of CPA, forex, commodity exposure, unconditional discounts, technical adjustment, present value and forecast invoicing rates.
B-BBEE level is scored from the CSD report, certificate or affidavit; a missing or invalid document scores zero PPPFA points where B-BBEE is not a pre-qualification criterion.
Specific goals are scored against supporting documentation; failure to meet them or to submit proof scores zero points without disqualification.
Price and specific-goal scores are added and bidders ranked highest to lowest under the 80/20 or 90/10 system.
Objective criteria under PPPFA section 2(1)(f) may be applied only if stated in the tender; functionality and B-BBEE scorecard elements cannot serve as objective criteria.
A reverse e-auction may be used, in which case bidders submit a complete tender without prices and any prices included are disregarded.
