Electrical Network Decentralisation Project - Hatfield Campus

Closing 5 June 2026 12:00

The University of Pretoria’s Hatfield Campus’ 11kV network consists of four main “ring” networks, all supplied by the 11kV Hilda Street Substation. The Hilda Street Substation in turn is supplied directly by the City of Tshwane from the Lynnwood Substation. Major load centres are supplied via local 11000/400V Substations, which also supplies smaller buildings in their immediate surrounds. Two of these load centres, the Human Sciences (HS) and Natural Sciences 1 buildings, are undergoing renovations, and the space occupied by these substations will be required to facilitate these upgrades. Furthermore, the decentralisation will also facilitate to establish proper separation between MV and LV areas, to ensure the authorised persons for each area can safely work without exposure to the other. This will be achieved by removing the MV switchgear and Transformers from the substations, and replacing these with Miniature, outdoor Substations. As part of this project, the electricity supply for the Data Centre (D/C), located within the Natural Sciences 1 (NS1) building, as well as the standby generator unit (SBG) 64 will be upgraded to enhance security of supply and make provision for planned expansion. See attached document for full details. Important Information: UP can only access tender submissions after the closing date and time has passed. Please take load shedding and site congestion into account and plan accordingly. If you need help with registration or online submission, contact See Documents.

Joint Ventures, Consortia and Subcontracting:

Most large tenders are composed of tasks in a number of different fields, and it is not always possible for a single company to cater for all of them, and therefore Joint Ventures and Consortia are formed to then submit a tender together.

Government tenders are also requiring the subcontracting of a percentage of the tender work, and the trouble is then finding Subcontractors to comply with the tender requirements

To assist companies with finding tender partners and subcontractors, you can now submit your contact details and company information on this page, so other interested parties can contact you for purposes of forming Joint Ventures and subcontracting
