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.

2014 Winter Graduation
2014-06-27

 
It is time for the 2014 Winter Graduation on our Bloemfontein Campus. From 2 – 4 July 2014 Masters and Doctoral degrees will be bestowed on graduates from across all seven faculties as well as the School of Open Learning. These include the conferral of Medicine degrees on the South African Cuban trainees.

Wednesday 2 July 2014 at 14:30: School of Open Learning
The School of Open Learning will confer a total of 609 degrees this year – almost double compared to the 320 of last year.

Thursday 3 July 2014 at 09:30: Faculty of Natural and Agricultural Sciences
Prof Magdalena Blum will receive an Honorary Doctorat, DPhil honoris causa, at this event. Prof Blum is an Extension Systems Officer in Rome. She works for a specialised agency of the United Nations called the Food and Agriculture Organization. This organisation’s mandate is:
• to improve nutrition,
• increase agricultural productivity,
• raise the standard of living in rural populations and
• contribute to global economic growth.

Her position serves to modernise and strengthen rural advisory services, their systems and networks worldwide. She has filled this position for almost nine years.

Prof Blum is driven by a passion for development, humanitarian work and female upliftment, but most of all, to enable people to help themselves.

Blum’s life has taken her from a small German village to Africa, Asia and Europe – and she has made an impact wherever she went.

Thursday 3 July 2014 at 14:30: Faculties of Economic and Management Sciences, Humanities, Education, Health Sciences, Law and Theology
At this ceremony, Faculty of the Humanities will award an Honorary Doctorate, DPhil honoris causa, on Prof Laura Mulvey. She is a feminist film theorist and worked at the British Film Institute for many years. She is currently a professor at Film and Media Studies at Birkbeck, University of London.

Prof Mulvey was prominent as an avant-garde filmmaker in the 1970s and ‘80s. In collaboration with her husband, Peter Wollen, she co-wrote and co-directed:
• Penthesilea: Queen of the Amazons (1974),
• Riddles of the Sphinx (1977, perhaps their most influential film),
• AMY! (1980),
• Crystal Gazing (1982),
• Frida Kahlo and Tina Modotti (1982), and
• The Bad Sister.

In 1991, she returned to filmmaking with Disgraced Monuments, which she co-directed with Mark Lewis.
