CONCO constructs new Heriotdale substation for City Power

November 2016 – CONCO is in the process of constructing the new 88/11/6.6kV Heriotdale substation for City Power including upgrading the existing Haggie Rand and PPC substations. City Power awarded the multi-million contract to CONCO in 2015 and the project is due for completion in the first quarter of 2018.

CONCO Senior Project Engineer Joshen Abraham says, “Power to the Heriotdale area is currently supplied from Haggie Rand Steel (Scaw Metals Group) and PPC Jupiter (PPC Cements SA) substations at 20.5kV, via cables from Cleveland substation. As a part of City Power’s network upgrade programme, the existing 20.5kV feed from Cleveland will be replaced to feed from the new Heriotdale substation at 6.6kV. The existing Haggie Rand and PPC substations will be decommissioned and a new substation building will be constructed and 6.6kV switchgear equipment installed, as the 20kV system is phased out at Cleveland. This all forms part of CONCO’s contract.”

Commenting about the project, City Power Project Manager Maete Thoka says, “I am very happy about the progress on site as well as the job opportunities that we have created, even if it is not on permanent basis, because these is a start and finish date to the project. For us as City Power, when the project is completed we will have enough capacity to cater for the developments around the area and what is also important is that we will be giving our key customers a stable supply. We are happy and delighted to have a company like CONCO to help us achieve our goals as they are very helpful, competitive and deliver quality services, and more importantly within budget and to the set timelines.”

The new 88/11/6.6kV Heriotdale substation will also supply power to the entire Heriotdale area on the south side of the M2 motorway, at 11kV’s, thereby catering for the imminent new industrial development in this area.

The existing Prospect to Cleveland 288kV line will be looped in and out into the new Heriotdale substation. Heriotdale substation will then be supplied from Prospect substation and standby will be provided from Cleveland substation.

Work being undertaken at Heriotdale substation includes: earthworks, civil and building works; installation of three 45MVA 88/11kV transformers, two 20MVA 11/6.6kV transformers, thirty-seven 11kV switchgear panels, twenty-six 6.6kV switchgear panels and associated secondary plant and equipment.

Both Haggie Rand and PPC substations will each have their own 6.6kV feeder board, 6.6kV cables and associated secondary plant and equipment.

“CONCO is committed to being socially responsible whilst developing our SMME community,” says Abraham, “as such, through the project, CONCO has appointed two community liaison officers (CLO’s) to be our interface to the community. Through these CLO’s, CONCO has already employed approximately 30 local labourers to work alongside the SMME contractors on the project, thereby creating additional capacity and ensuring skills transfer to previously unskilled labour.”

Completion of the project will bring about improved capacity in the area and will ensure that future feeds are catered for.
