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.

Tourism Month was celebrated in style at our Qwaqwa Campus with the hosting of the first ever Public Tourism Lecture. The lecture was part of the national Tourism Month celebrations and was organised by the National Department of Tourism in partnership with the UFS, the Central University of Technology, Free State and the University of Johannesburg (UJ).

The keynote address was presented by UJ’s Ms Milena Ivanovic, whose paper was entitled Cultural Tourism – Global and Local Perspective. This presentation was followed by a discussion by a panel of experts, namely Prof. Doreen Atkinson, Ms Merle Naidoo (both from the UFS), Prof. Albert Strydom (CUT), Dr Webber Ndoro (African World Heritage Fund), Ms Leonore Beukes (Department of Tourism) and Dr Kevin Mearns (UJ).

In acknowledgement of the role that institutions of higher learning play in advancing the tourism agenda, Minister of Environmental Affairs & Tourism, Marthinus van Schalkwyk, said that South Africa was now in a better position to welcome tourists compared to pre-1994.

“Before 1994 we had less than 500 000 foreign arrivals in the country while in 2010 we had over 10 million of whom 8 million were tourists. In 2006 only 26 airlines were using our airports, but now there are over 50 airlines,” he said.

Also in attendance were Free State MEC for Economic Development, Tourism and Environmental Affairs, Mxolisi Dukwana, and the UFS team led by Qwaqwa Campus Principal, Dr Elias Malete, and Vice-Rector: External Relations, Dr Choice Makhetha.

The Tourism Month festivities were concluded by a tough, but informative Poster Presentation Competition that pitted UFS, UJ and CUT students against each other.
