Filter Maintenance and Supply Services – Grootvlei Power Station

Eskom Holdings SOC Ltd, South Africa's state-owned electricity utility, has issued an open Invitation to Tender for the maintenance of coalescers and mobile purifiers and the supply of all different types of filter elements at Grootvlei Power Station. The contract runs for a period of five years and is structured on an as-and-when-required basis, meaning work and supply will be called off according to operational needs rather than a fixed volume. The scope covers both routine (planned) and non-routine (unplanned or breakdown) maintenance of coalescers and mobile purifiers, which are critical for removing water, oil, and contaminants from plant fluids and gases, as well as the procurement of the full range of filter elements used across the station. The tender is governed by the NEC3 Engineering and Construction Contract conditions and the Eskom Standard Conditions of Tender. Evaluation is based on the 90/10 or 80/20 preference point system (depending on contract value), with a minimum 70% functionality threshold, and objective criteria apply under Eskom's Supplier Development and Localisation (SDL&I) strategy.

Key requirements include a valid CSD registration, a valid B-BBEE certificate or sworn affidavit, a tax compliance status (or PIN), a completed integrity declaration, and SBD forms (including SBD 1, SBD 4, and SBD 6.1). Tenderers must also provide a SHEQ framework covering environmental management, a SHE Officer appointment, and COIDA good standing. Local procurement content is targeted at 100%, with a designated-group procurement target of 1% for transportation activities. Bidders are expected to submit a B-BBEE improvement plan within 30 days of contract signature, provide skills development proposals (including two mechanical fitter and two electrician artisan positions), and report SDL&I compliance quarterly. A penalty of 2% of contract value applies for non-compliance, with 2% of each invoice retained as security. Because the buyer's estimated value and foreign content are not fully disclosed in the documents, bidders should confirm whether NIPP obligations (applicable above USD 5 million in imported content) apply.

The clarification meeting is held virtually via Microsoft Teams on 26 November 2026 (13h00–15h00), and tenders must be submitted electronically through the Eskom E-tendering portal by 10h00 on 15 January 2027. The tender validity period is 180 days from closing. Suppliers should review the full ITT, SDL&I strategy, and pricing schedule (in both PDF and Excel formats) before submission. Early engagement with the Eskom Representative, Michael Dube, through written queries is strongly advised, as queries must not be directed to other Eskom officials.
