Electrostatic Precipitator Maintenance Services

Eskom Holdings SOC Ltd has issued an open Invitation to Tender (E3735GXMPLET) for the maintenance of the electrical precipitator plant at Lethabo Power Station. The contract covers as-and-when-required maintenance work over a period of five years. Electrostatic precipitators are emission-control systems that remove particulate matter from flue gases at coal-fired power stations, so reliable maintenance is critical to both plant availability and environmental compliance. The work will be delivered under the NEC3 Term Service Contract (TSC) with Option A (priced contract with price list), dispute resolution procedure W1, and secondary options including price adjustment for inflation (X1), changes in the law (X2), low service damages (X17), limitation of liability (X18) and task orders (X19). A performance bond (X13) may be required depending on the outcome of a financial analysis.

To be considered, tenderers must meet eligibility criteria, be CSD-registered, and provide a complete commercial, financial and technical submission through Eskom's e-tendering portal. Functionality scoring (threshold 80%) assesses key personnel CVs (including a construction supervisor, a safety officer with SAMTRAC or SAIOSH membership, twelve qualified electrical artisans, and an NQF Level 5 electrical or supervision qualification), company registration with the Department of Labour as an electrical contractor, previous experience on similar electrical plant maintenance (evidence of up to four completed contracts), knowledge of precipitator technology, detailed method statements covering the scope of work, and a skills-transfer programme for Eskom employees. Price is scored out of 90 and specific goals out of 10 under the 90/10 preference point system. Required documents include a Quality Control Plan within three weeks of contract date, COIDA certificates of good standing, a Pricing Schedule in PDF and Excel formats, and, for JVs, a jointly and severally liable JV agreement. Contract price adjustment must comply with Eskom's CPA rules, including a minimum 15% fixed portion.

Key dates are a non-compulsory clarification meeting on 5 November 2026 at 13:00 (MS Teams) and a closing date of 11 November 2026 at 10:00, with a tender validity period of 120 days. Payment terms are 30 days for contracts below R50 million including VAT and 60 days above that threshold. Late submissions will not be accepted, alternative tenders are not allowed, and the tender is for the whole of the contract. Interested parties should review the full ITT pack, including the scope of work and pricing schedule, on the Eskom e-tendering portal.
