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.

Paired Peers: Pathways to social mobility—Investing in the future? Moving through HE and into employment was recently presented to staff and postdoctoral students by Prof Ann-Marie Bathmaker, from the University of Birmingham, during her visit to South Africa while working on the Miratho Research Project with CRHED. Prof Bathmaker’s research interest particularly focuses on issues of equity, social mobility, and social class inequalities. Her presentation, the second in the Higher Education Research Seminar series presented by CRHED, was based on research resulting from a seven-year project in England.

In the UK, higher education (HE) is considered a key route to social mobility. Interest has grown in graduate destinations, particularly the prospects and obstacles faced by graduates from different social backgrounds. Paired Peers followed 70 students throughout their undergraduate studies and into the working world.

The project explored the processes of social mobility, highlighting different orientations and practices towards investing in the future, which ranged from investing in the present to cultural entrepreneurship for the future.

Participants were selected from two universities in Bristol, England. The research team focused on three key themes: “Getting In” (access to HE), “Getting On” (financial limitations, friendships, accommodation), and “Getting Out” (holiday work, internships, and finding suitable graduate employment).

Prof Bathmaker was able to highlight key research findings, many of which resonated with those attending. From the question-and-answer session, it was clear that many issues regarding inclusivity, whether across gender, ethnic, or language barriers, find their parallels in the South African context and can be of benefit to higher education practitioners here.
