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.

Standing ovation for the UFS Camerata in St Petersburg, Russia
2013-11-26

The OSM CAMERATA (OSMC), flagship ensemble of the University of the Free State’s Odeion School of Music, received a standing ovation during a gala concert at the 13th International Conservatoire Festival presented on 7 November 2013 in the Glazunov Hall under the baton of Maestro Jan Moritz Onken.

The International Conservatory Festival was founded in 2001 by the St Petersburg Rimsky Korsakov Conservatory and has since then become an annual highlight on the concert calendar of St Petersburg.

For the last thirteen years, the festival has developed as a centre of excellence for artists, lecturers, and music experts who represent higher institutions of music from almost every continent. This forum has introduced more than 200 conservatories internationally, and literally produced hundreds of concerts, master’s classes and lectures. Internationally-acclaimed musicians such as Yuri Temirkanov, Rodion Shchedrin, Saulius Sondeckis, Krzysztof Penderecki, Valery Gergiev, Vasily Sinaisky and Semyon Bychkov, as well as young talented performers on the brink of their international careers, have participated in the festival over the years.

The OSMC presented the artistic director of the festival, Prof Lydia Volcheck, with audio-visual material as an audition and received a formal invitation from Prof Mikhail Gantvarg, Rector of the St Petersburg Rimsky Korsakov Conservatoire, in May 2013. Jan Moritz Onken (who was appointed as the OSMC chief conductor and artistic director for 2012) prepared the ensemble with vigour and discipline. Experienced international OSM alumni and several young international professionals served as mentors throughout the year preceding the event.

The OSMC gave two recitals during the festival – a gala performance in the Glazunov Hall, as well as a concert in the St Petersburg White Hall. For the first concert on 7 November (entitled FOUR CONTINENTS FESTIVAL), the OSMC shared the stage with a piano duo from the Karol Szymanowski Academy of Music (Katowice, Poland), the String Quartet of the Colburn Conservatory of Music (Los Angeles, USA), as well as an ensemble of Japanese Traditional Instruments from the Tokyo University of the Arts (Japan).

After the last reverberating notes of the performance of the Phantom Waltz (a work commissioned by the OSM from the South African composer Hendrik Hofmeyr), a thunderous applause and shouts of bravo exploded! The OSMC responded spontaneously with a kwela improvisation as an encore.
