S.Africa: CONCO reports progress on Sebenza project

On Thursday, CONCO senior project manager Thamie Nyembe stated that the team working on the project has completed all the offsite activities including the delivery of 95% of the equipment.

The company noted that work on the Sebenza substation project began at the end of 2014 following the awarding of the contract by City Power.

“In just over a year, we have conquered a vast portion of this key multi-phase project…which is due to meticulous project planning, management and control.

“At present, we have completed all offsite activities being the design, engineering and procurement and have taken delivery of approximately 95% of the equipment,” Nyembe said.

CONCO- scope of the project

The Sebenza substation is located adjacent to the Kelvin substation in the north of Johannesburg, Gauteng Province, and according to the company will help relieve the power load demand on the old coal-fired station.

CONCO explained that the project involves the construction of a new 1,000MVA, 400/275/88kV bulk in-feed substation, upgrades and additions to prospect substation, and at Kelvin substation, four sets of reactors and new switchgear on some of the main feeders.

Construction manager Jan Ehlers commented: “The majority of the earthworks and civil work is complete as well as the construction of a three-storey GIS building that will house the 132kV GIS switchgear, as well as the protection, control and SCADA systems…”

He added: “We are now entering the bulk of the installation and commissioning phase of the project where numerous major contractors will be on site, thereby requiring effective management.

“To ensure that this phase runs smoothly, we have implemented a multi-level/multi-disciplinary scheduler.”

“PSW/Nyeleti Consulting Engineers headed by Sarel Peens and Hein Schuld appointed a full time civil resident engineer, Japie Kotze, to ensure that civil work is carried out to the required standard and, where necessary, that adjustments to drawings are made in order to overcome challenges and therefore minimise expenditure,” explained Ehlers.

City Power’s project manager Godfrey Mulaudzi also commented: “As we enter the installation and commissioning of apparatus into the grid, we still want to assure our customers of continuity of supply and minimum outages when necessary. All outages will be communicated to our customers in time.”
