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 on the right track with transformation - Fulbright scholars

“I think the university is not only on the right track but can really become a model for how to negotiate certain difficult processes, such as transformation, within a short period of time. I think it can become a model, not just for other universities, but also for the world.”

This was said by Dr Rozetta Wilmore-Schaeffer, who together with Rev. Dr Frederick J. Streets, recently worked with the International Institute for Race, Reconciliation and Social Justice at the University of the Free State (UFS) as Fulbright specialists. They helped the institute come up with ideas in terms of making the changes that are necessary for the transformation of the university.

“There is a great deal that has already been done despite the sense of urgency and impatience, and I think there is a great deal more to be done,” said Dr Wilmore-Schaeffer.

“I think this sense of urgency comes from those who are involved in the process of looking at the destination, the place that they want to be at, and feeling that they are very far from it.”

During their visit here the two had numerous conversations with both staff members and students.

“I have been most impressed by the students who I think are ready to make changes in many different ways – I am talking about students of all racial groups and gender. The fact that they are referring to transformation as ‘their struggle’ shows that they are prepared to make changes,” said Dr Wilmore-Schaeffer.
She, however, cautioned that there were those who were still against transformation taking place at the university.

“I think there is still some resistance from some quarters on both sides of the fence and I would expect that at this point in time. I think what is really hopeful is that there are so many students who are ready to make the changes, who are making the changes, who are struggling with issues around making the changes; and I think that is really the hope for the university and the hope for the future,” she said.

“The resistance is complex,” added Rev. Dr Streets. “It is around a fear for the future, the loss of identity on the part of both black and white students, and the desire for cultural continuity amongst white students as well as amongst a variety of ethnic black students.

“The resistance is about learning that you are not the only kid on the block anymore and how you then overcome the feeling of realising that you are not the dominant person anymore and that your culture is not the dominant culture anymore.”

They have given a preliminary report of their findings to the Rector and Vice-Chancellor of the UFS, Prof. Jonathan Jansen, which will be followed by a more detailed report later on.
