Supply, delivery, installation and commissioning of one new 250 kVA silent diesel generator set with automatic transfer switch for Vuselela TVET College's Taung Campus. Bidders must hold valid CIDB EP Grade 1 registration and provide three reference letters for backup systems of 250 kVA or higher.

Detailed Description

Vuselela TVET College, through its Supply Chain Management office, is seeking a qualified supplier to provide, deliver, install, test and commission one (1) new and unused 250 kVA three-phase diesel generator set for its Taung Campus. The generator must be a silent, weather-resistant canopy unit rated at 250 kVA prime power and 265 kVA standby power, operating at 230/400 V, 50 Hz and 1,500 rpm. The specification calls for a six-cylinder, water-cooled, turbocharged diesel engine with electronic governor, a 500-litre fuel tank, a brushless self-regulating alternator with AVR, and a digital controller offering automatic and manual start with comprehensive monitoring and fault protection. The scope also includes an automatic transfer switch (ATS) with associated control and interconnection wiring, offloading and positioning, electrical connection, and commissioning including manual and automatic transfer tests and a load test.

Successful bidders must deliver a full documentation package, including operating and maintenance manuals in English, electrical and wiring diagrams, factory test certificates, a signed commissioning report, a warranty certificate (minimum one year or 1,000 operating hours), and a list of recommended consumables and critical spares. Mandatory returnable documents include a valid CSD report (not older than three months), CIDB registration at EP Grade 1, three reference letters with completion certificates for backup power installations of 250 kVA or higher in institutions with large rooms (minimum 8m x 8m) including student residences, CIPC documents, a tax PIN, identity documents, an official quotation on letterhead that includes all related costs, a project installation plan, a draft maintenance plan of no more than one page, and an offer of material credit for the existing generator. A compulsory virtual briefing session takes place on 30 October 2026 at 11:00, and submissions close on 13 November 2026 at 11:00 via email.

The tender uses the 80/20 preference point system, with 80 points for price and 20 points for specific goals, including ownership by Black people, women, and people with disabilities, and locality within Taung. Bidders should note that electrical work must be performed by qualified and legally authorised personnel in line with South African wiring rules, and that fuel piping, bunding, civil works, craneage and cabling are excluded unless priced separately. This opportunity offers a meaningful contract for an established power equipment supplier and installer, with clear technical benchmarks and a well-defined handover process.

Suitable Businesses

Suitable for generator and power equipment suppliers, electrical contractors and installers holding CIDB EP Grade 1 registration, with experience installing backup power systems of 250 kVA or higher, particularly in educational or institutional settings. Businesses must be able to provide an official quotation, supporting compliance documents, and an installation plan. Companies that qualify for the locality or ownership specific goals, such as Black-owned, women-owned or disability-owned enterprises based in or serving Taung, may benefit from additional preference points. Pure equipment traders without installation and commissioning capability, or without the required CIDB grading, are unlikely to meet the responsiveness requirements.
