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.

Theatre, photography, literature, and lectures: TFR Studies to showcase their success
2016-11-29

The end of the year usually introduces a mood of reflection on what was and what could have been. For Trauma, Forgiveness and Reconciliation (TFR) Studies at the University of the Free State, the past year recalls a flourish of achievements worth celebrating.

Therefore, TFR Studies held an end-of-year event to showcase the successes of 2016. This comprised lectures from leading researchers in social sciences and housing rights, the release of three new books, a theatre production, and a photo exhibition.

Lectures
Prof Anthony Collins – a leading scholar in identity and culture – will speak about violence in contemporary South Africa. Prof Collins, who holds a PhD from the University of California, Santa Cruz, has extensive knowledge in the interdisciplinary area of critical social sciences and won two national awards for teaching and learning.

In addition, housing rights activist Faeza Meyer will share her experiences of forced eviction and violence in Kapteinsklip, Western Cape. She will also talk about the process of documenting these experiences and working together with feminist historian Koni Benson.

New books
Breathe in the smell of fresh ink as Dr Samantha van Schalkwyk, Dr Kim Wale, and PhD candidate Naleli Morojele introduce their books to the public. Themes of violence and gender – pertinent to South Africa – thread through each of these books in unique ways.

Theatre
The award-winning play, AVU – directed and produced by Michelle Hoffman who is a master’s student at TFR – will be performed. The story dances between the blurry lines of reality and fantasy, between Boer and Bantu.

Photo exhibition
Lerato Machetela, a PhD candidate with TFR, has featured as one of SA’s Heroes for her work among the youth of Jagersfontein. Through an innovative method, Machetela is employing an arts-based approach to research through PhotoVoice. The result: a photo exhibition by the youth of Jagersfontein – and a rare opportunity to see the world through the eyes of a child.
