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 hosts the first Southern African Young Scientists Summer Programme
2012-11-26

The University of the Free State is to host the first Southern African Young Scientists Summer Programme (SA-YSSP) from 1 December 2012 to 28 February 2013. 

This will form part of an annual three-month education, academic training and research capacity-building programme jointly organised by the National Research Foundation (NRF), the Department of Science and Technology (DST), and the International Institute for Applied Systems Analysis (IIASA), based in Austria.
 
The NRF, as the National Member Organisation (NMO), in collaboration with DST, has developed a novel and innovative initiative with IIASA to establish the SA-YSSP. This programme was officially launched by the Minister of Science and Technology during November 2011.
 
IIASA is an international research organisation that conducts policy-oriented scientific research in the three global problem areas of energy and climate change, food and water and poverty and equity (www.iiasa.ac.at). South Africa’s engagements with IIASA, and specifically with regard to the SA-YSSP, relate primarily to the DST’s Ten-Year Innovation Plan.
 
Aligned with the YSSP model that is presented by IIASA in Austria annually, the SA-YSSP offers scientific seminars covering themes in both the social and natural sciences. These seminars often have policy dimensions and aim to broaden the participants’ perspectives and strengthen their analytical and modelling skills, further enriching a demanding academic and research programme (www.ufs.ac.za/sa-yssp).
 
Keynote lectures are to be delivered by national and international leaders in their respective research fields, partly drawn from IIASA’s widespread network of alumni and collaborators, as well as from the NRF’s extensive international networks of excellence.
 
The programme is to be enhanced with specific field trips and cultural and heritage excursions that will involve networking with locally based research programmes. Supervisory teams of both IIASA and South African experts will guide a cohort of competitively selected South African and international advanced Ph.D candidates.
 
The programme will be opened on 2 December 2012 at the Centenary Complex by the Minister of Science and Technology, Mr Derek Hanekom, the Director/CEO of IIASA, Prof Pavel Kabat and the Vice-Chancellor and Rector of the UFS, Prof Jonathan Jansen. They will be joined by a number of Nobel Prize Laureates and luminaries representing the government, the diplomatic sector and Higher Education.
 
The programme is directed by a multidisciplinary team at the UFS that includes:
Prof Aldo Stroebel and Prof Neil Roos (Co-Directors)
Prof André Roodt (Dean of SA-YSSP)
Prof Martin Ntwaeaborwa and Dr Henriëtte van den Berg (Deputy-Deans of SA-YSSP)
Dr Priscilla Mensah and Dr Sonja Loots (Strategic Managers)
