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.

Speech:"The future of South Africa in Africa" (pdf)

The Centre for Africa Studies received praise for the series of dialogues it hosted on the ruling ANC party, conversations which started before the party held its 53rd National Conference on our Bloemfontein Campus.

The Centre recently hosted the last seminar in the ANC Centenary Dialogue series, a project which started in November 2010 when the ruling party prepared for its centenary celebrations in 2012.

Prof Kwandiwe Kondlo, former Head of the Centre, and currently professor at the University of Johannesburg, told guests at the closing seminar, "it was a job well done which kept dialogue going on". Prof Kondlo said a book with a collection of papers presented during the series is being finalised, with senior ANC officials expected to attend the book launch on the Bloemfontein Campus later this year. The book features chapters by scholars like Profs Stephen Ellis, Shireen Hassim, Colin Bundy and Ben Turok and covers topics on the role of women in the liberation struggle, the party's economic policy and the history of the party in exile.

Speakers at the closing seminar included Prof Kwesi Prah, whom Prof Kondlo introduced as "one of Afica's intellectual giants,” struggle veteran, Dr Dennis Goldberg and the new Head of the Centre for Africa Studies, Prof Heidi Hudson.

Prof Prah, who delivered the keynote address, spoke about "The future of South Africa in Africa."
