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.

Team UFS flexes its debating muscles

Team UFS flexes its debating muscles

Friday 24 July 2015 marks the day when the University of the Free State Debating Society (UFDS) outperformed the University of Cape Town (UCT) at the UCT 150th anniversary celebration of its debating union.

Representing Kovsies were Zola Valashiya, Ntsapi ‘Neko, Nkahiseng Ralepeli, Lehakoe Masedi, and Thabang Thembani, who fought bravely for a spot in the finals.

Masedi and Ralepeli broke into the semifinals after seven preliminary rounds, eventually winning the competition. The two students were up against three UCT teams, comprising the current National Champions and Pan African finalists.

This follows the debaters’ outstanding performance at the 2015 South African National University Debating Championship (SANUDC), hosted by the University of Venda. The UFDS commemorated a decade in existence by participating in its 10th national tournament.

After nine preliminary rounds, two teams broke into the grand finals of the two categories: English as a second language (ESL) and English as a first language (EFL). Devon Watson and Nkahiseng Ralepeli were the EFL team who fought their way through to the finals, beating UCT and the University of Botswana.

The inaugural Wits Women’s Debate Open (2014) title holders, Lerato Leteane and Lehakoe Masedi, represented Kovsies as the ESL finalists against the University of Nambia. The ladies rose to the occasion, but eventually emerged just one point short of the Namibian team’s four-point win.

Nonetheless, they were satisfied with their competitive skills, utilising the platform to address the lack of female debaters in the Southern African debating circuit.
