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.

Kovsie Netball team aims for first home final on Monday 12 October 2015
2015-10-09

Kovsies Netball has been unbeaten this year.

The University of the Free State (UFS) netball team  is hoping to continue its good performance in the Varsity Sport series against the North-West University on Monday 12 October 2015 at 19:00, in order to reach the finals for a third consecutive year.

The teams will meet in the Callie Human Centre on the Bloemfontein Campus for a follow-up of last year’s semi-final. Kovsies won that that game in Bloemfontein with a score of 51-45.

If the home team prevails, they will be hosting a final for the first time.

The Kovsies, who were unbeaten this year, and finished at the top of the log, were the champions in the first two seasons, but had to play away from home in the final against Pukke in 2013 and Tuks in 2014.

The last league match they lost against Pukke was in 2013. The score in Pretoria was 47-60 in favour of the Pukke.

Many of the clashes between the teams have been very close games. Last year, there was a 45-45 draw in Potchefstroom.

In the first round of 2015 between Kovsies and Pukke in Bloemfontein, the UFS won by 47-38.

In their final league match in Stellenbosch on Monday 5 October 2015, Kovsies won against Maties by 41-33, while the Pukke, who ended fourth on the log, defeated the Madibaz 65-32 in Potchefstroom.

In the other semi-final on Monday, Tukkies and Maties, second and third respectively on the log, will play against each other in Pretoria. This match will be broadcast live on a big screen in the Callie Human Centre on Monday.

The Kovsie captain, Karla Mostert, who will be playing for Bath in England next year, is currently ahead on votes for Player of the Series. Last year, she was also Player of the Series. Fans may vote for her on the Varsity Sport Facebook page at https://www.facebook.com/varsitysportsSA.
