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.

Vocal student invited to Summer Academy in Austria
2011-08-25

 

Theresa de Wit

One of our students, Teresa de Wit, joined some of the world’s most gifted young singers at the International Summer Academy in Salzburg this week.

Teresa, a B. Mus. Honours student under the tutelage of Petrus van Heerden from the University of the Free State’s Odeion School of Music (OSM), has been selected to participate in master classes presented by applauded soprano Barbara Bonney.

The Mozarteum Music University hosts the International Summer Academy in Salzburg every year during July and August. It has become one of the world’s biggest and most renowned institutions of its kind, offering 60 master classes for between 800 and 1 000 participants. Founded in 1916 by Lilli Lehmann to teach voice, the programme was expanded over the years to include violin, piano, composition, and conducting and opera courses. It was named the Mozarteum International Summer Academy in 1947.

During the six-week summer academy, the crème de la crème of professional artists share their expertise during two weeks of intensive courses. Over the years the summer academy has also become the scouting ground for the foremost music agencies of Europe and the United States of America.
