Solar Panels at UFS Qwaqwa Campus
Revolutionising electricity with sun power: Solar panels at the Qwaqwa Campus.

Over the past few years the University of the Free State (UFS) has been planting panels, now the time has come to reap. Solar farms produced a return on investment in the form of R1.4 million in savings as a result of photovoltaics (PV) between January and March 2019. Nicolaas Esterhuysen, an electrical engineer at the Department of University Estates also reported a 2.34% decline in electricity usage between 2013 and 2018. 

Solar panels are the future 

According to Esterhuysen, the solution to a power crisis lies in “either becoming more energy efficient or generating our own at a cheaper cost”. All campuses have managed to save a total of R5.4 million in 2018 through producing our own power (solar PV) and actively managing the instantaneous load demand with building management system (BMS) software.

Overall, ground-mounted PV installations at all campuses contribute 2609 kilowattpeak (kWp) under standard conditions. The Bloemfontein Campus accounts for 979kWp of that amount while the South Campus generates 762kWp, with the Qwaqwa Campus producing 748kWp, and the Paradys experimental farm bringing in 120kWp to the grand total (to be commissioned June 2019).

Rooftop PVs generate electricity through the 80kWp Muller Potgieter Building, the 255kWp Bloemfontein Campus computer lab, the 35kWp Qwaqwa Campus computer lab, 135kWp Qwaqwa Campus Mandela Hall, and 416kWp Thakaneng Bridge panels. This is a total of 921kWp. 

Winter is coming with tariff terrors 

A 15.63% electricity tariff increase is projected this year in light of the annual winter adjustments commissioned by Eskom and Centlec. To gear up for the associated spike in power use over this season, University Estates advises the Kovsie community to use energy efficiently. “Think twice before switching on the heating and make sure to switch it off when you leave the office,” advises Esterhuysen.

In addition to generating electricity, saving initiatives such as implementing light-emitting diode (LED) lighting with motion sensors and actively managing demand at peak times have been implemented.

What’s next?

The next step is to rethink dated mechanical installations that are used to heat some of our older buildings. Replacing similar installations across all of the campuses are some of the ways the university intends to escalate energy efficient in future.

UFS receives R3,284 million to research biosafety of genetically modified crops
2009-03-17

A testing facility at the University of the Free State (UFS), which is the only one of its kind in South Africa and a leader in its field in Africa, has received a grant of R3,284 million from the South African National Biodiversity Institute (SANBI) to do research on the biosafety of genetically modified crops in South Africa.

Prof. Chris Viljoen of the Genetically Modified Organisms (GMO) Testing Facility at the UFS says the grant forms part of a collaborative agreement between South Africa and Norway on the biosafety of GMOs.

The grant also makes provision for two M.Sc. bursaries as well as a regional biosafety workshop.

The research will focus on gene flow between genetically modified (GM) maize and non-GM maize and the potential impact thereof on the development of insect resistance.

Prof. Viljoen, who is head of Human Molecular Biology in the Department of Haematology and Cell Biology, says it is an honour to be selected to take part in the project and is groundbreaking in terms of GM maize on the environment. The project was initiated in 2009 and will run until the end of 2010.

The multi-institutional research include partners from the UFS, research groups from the University of North-West, the University of Fort Hare as well as SANBI and GenØk, the Norwegian centre for Gene Ecology. The GMO Testing Facility at the UFS was established in 2003 to perform routine GM detection for grain and food products in South Africa. The activities also include research into GM detection and biosafety of GM crops.
