Telkom’s grid-tied photovoltaic solar power plant has generated over 3.75 megawatts of electricity since it came online in July 2016.
The 3MW plant was constructed at Telkom Park, the company’s headquarters in Centurion.
“The average daily energy production sufficiently augments Telkom Park’s energy needs during daytime peak electricity demand, with over 4,000 staff, which excludes the data centres,” said Telkom.
Telkom reported that its overall electricity consumption at its headquarters decreased by 9% year-on-year, thanks to:
- The implementation of 50 smart meters to measure electricity consumption in key buildings.
- Roll-out of LED lighting, which replaced conventional lighting systems in 900 buildings across SA.
- The implementation of a building management system at the head office.
Its new automation system at Telkom Park monitors and controls multiple facilities elements, including air conditioning, power distribution, lighting, and water usage.
Telkom said that at several of its larger sites, water harvesting and recycling plans are also at an advanced stage.
“The head office will be able to offer its staff and visitors the use of six electric vehicle charging points, connected to the solar PV plant at no cost,” added Telkom.
“Implementation of air cooled heating, ventilation, and air conditioning systems in our head office is underway to reduce the amount of water used for cooling in data centres.”
