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.

UN-recognised scholar awarded the prestigious TRI Annual PhD Award

Two years after enrolling as a PhD candidate in the University of the Free State’s (UFS) Department of Political Studies and Governance, Dr Anneli Botha was awarded the annual Terrorism Research Initiative (TRI) Award for the 'Best Doctoral Thesis on Terrorism and Counter-Terrorism' (2014).

The TRI PhD award is a prestigious international honour, while terrorism as a scholarly venture remains a concentrated field. Dr Botha, one of the few women in this niche field, has proved to be an excellent asset. Her winning of the prestigious award was announced in its October 2015 issue of Perspectives on Terrorism (PT), a globally-circulated online journal, co-published by the European-based Terrorism Research Initiative and the America-based Center for Terrorism and Security Studies.

Based on the merit and relevance of her outstanding research, the United Nations Development Programme has appointed Dr Botha as a Consultant on Radicalisation. In addition, her PhD is to be published as a book in the United States of America early in 2016. She was appointed as a Research Associate at the University of the Free State at the beginning of this year.

An award-winning search for answers

Her thesis, titled “Radicalisation to Terrorism in Kenya and Uganda: a Political Socialisation Perspective”, tackled East African militancy, from an individualised perspective. Researchers in the past have neglected assessing details of the rebels’ childhoods. Dr Botha’s interviewed about 285 militants and their families. These individuals declared themselves openly as members of al-Shabaab and the Mombasa Republican Council (MRC) in Kenya, and the Allied Democratic Forces (ADF) and the Lord’s Resistance Army (LRA) in Uganda, at the time of the interviews.

Her doctoral dissertation provides significant information about factors that should be considered in the quest to counter and prevent terrorism. Her research shows conclusively that political socialisation begins with the family, and expands through peers, school, media, and earlier political experiences, culminating in the terrorist group.

Outstanding piece of scholarship

Dr Alex Schmid, who is the editor of PT, TRI Award Jury chairman, and one of the most respected experts of terrorism, described Dr Botha’s research as an “outstanding piece of scholarship.”

Dr Botha attributed her success to her supervisors - Professors Theo Neethling and Hussein Solomon - as well as to the people in Kenya and Uganda.
