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.

Nadine Gordimer lauds university for transformation

Lecture (Pdf format)

Renowned writer and Nobel Prize winner Nadine Gordimer has lauded the university for its efforts at reconciliation, highlighting several initiatives the university has put in place over the last few years.

She delivered the inaugural Reconciliation Lecture on the Bloemfontein Campus, and was introduced as a “champion of human oneness” by Prof. Pumla Gobodo-Madikizela, Senior Research Professor on Trauma, Forgiveness and Reconciliation, who also referred to Gordimer as “the living expression of the power of critical consciousness”.

Gordimer praised the university by saying it was doing things in South Africa differently from what had been done during the country’s shameful past. In a message addressed at students, her lecture touched on topics of race, reconciliation, freedom of expression, education, inequality and poverty.

“Black and white – we have been conditioned; no, brain-washed, by legal and cultural and even religious, demeaning distinctions between race and colour. This university has discarded; is tackling these: an image breaking of false consciousness. We await your generation’s entry to public life, when you come out of the University of the Free State equipped to bring to us, along with your professional degrees, the way to function in a population as the human beings you have learnt to be at this university.”

The Nobel laureate also warned students of threats facing South Africa’s future.

“What is your reaction, then, to the Protection of State Information Act, the Secrecy Act that has been drop on our heads? The Secrecy Act means that we the people are not allowed to know the facts about our own country. Know how our society, our population is manoeuvred by those entrusted and empowered by our votes.”

The inaugural lecture was hosted by the Vice-Chancellor and Rector, prof. Jonathan Jansen, and the Rectorate, with the support of the Institute for Reconciliation and Social Justice and Prof. Gobodo-Madikizela.
