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 Postgraduate student council’s community project a success

Description: UFS Postgraduate council’s community project a success Tags: UFS Postgraduate council’s

Prof Jansen Vice-Chancellor and Rector, Dr Henriette van den Berg, Director of Postgraduate School, and Mr Gustav Wilson, Regional Head: Development and Care, Free State and Northern Cape Region.

The University of the Free State’s Postgraduate Student Council embarked on a courageous community engagement project for Mandela Day in 2015. The programme was aimed at assisting offenders at Tswelopele Correctional Centre pass their matric exams, thus granting them access to tertiary education.

The Postgraduate Student Council assisted the 2015 matriculants with study support, and motivated them during their final examinations in 2015. The council will play a bigger role this year by offering offenders at Tswelopele career advice and career guidance for when they leave the correctional facility, as well as study techniques to assist them throughout the year, to ensure a 100% pass mark in 2016.

Offenders who had participated in the Postgraduate Student Council project attended the Postgraduate School’s Open Day on 19 February.  Of the 12 offenders, 11 passed their matric exams, while one is currently busy with his supplementary exams. Tswelopele has a 92% pass rate; it is the best performing correctional centre in South Africa.

The Tswelopele Correctional Centre also serves as a full-time high school (Grade 10-12), and TVET College, assisting offenders to register for tertiary education through various universities.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State, said that he was immensely proud of the matriculants from Tswelopele Correctional Centre. He added that it is vital for every human being to receive a second chance. “Rehabilitation programmes are meant to give offenders a second chance at life, because we cannot give up on humanity. Correctional centres and rehabilitation centres are a societal responsibility. Society must not give up on offenders, everyone deserves a second chance, and we cannot give up on humanity.”

“To our offenders going through rehabilitation and all our young people who are our hope for the future of our beloved country, be encouraged. Dream again. Discover the wonder in your lives,” said Mr Gustav Wilson, Regional Head: Development and Care, Free State and Northern Cape Region.
