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.

Odeion School of Music Camerata to perform in Russia

OSM CAMERATA "Die Spokewals" by Hendrik Hofmeyr under the baton of Jan Moritz Onken (YouTube)

After a successful audition, the Odeion School of Music Camerata (OSMC) received an invitation to participate in the 13th International Conservatory Festival which will take place in St Petersburg, Russia, from 1 to 9 November 2013. The festival is a yearly highlight on the concert calendar of the prestigious Rimsky Korsakov Conservatoire.

The artistic panel of the festival, under the leadership of Prof Lydia Volchek, annually selects ten international conservatories to gather in St Petersburg for the festival. Some of the participants include the Tchaikovsky Conservatoire: Moscow, Conservatoire de Paris, Eastman School of Music NY and the Sibelius Academy in Helsinki Finland. According to the Rector of the Rimsky Korsakov Conservatoire, Prof Mikhail Gantvarg, it will be the first ever school of music hailing from Africa to participate in the festival.

The OSMC was requested to give two recitals of 40 minutes each during the festival. Maestro Jan Moritz Onken (Chief Conductor of the OSMC for 2013) will lead the ensemble to St Petersburg. OSMC members will have the opportunity to attend all concerts presented by fellow participants as well as masters’ classes presented by the masters of St Petersburg Conservatoire.

The festival is usually opened and closed with a grand concert presented by the St Petersburg Conservatoire Symphony Orchestra (70 plus members). Last year the opening concert was conducted by the celebrated master, Valery Gergiev (artistic director of the Mariinsky Opera and Symphony Orchestra), while the closing ceremony was conducted by Semyon Bychkov – reciting the Leningrad Symphony by Shostakovich. Both Gergiev and Bychkov are alumni of the St Petersburg Conservatoire.

All recitals at the festival will be presented in the Opera and Theatre Hall of the Conservatoire, as well as in the acclaimed Glazunov Concert Hall located within the colossal conservatory building.

The OSMC will recite a programme of mainly South African composers, with two new works commissioned by the OSM New Music Initiative. These were written by the prolific South African composer, Hendrik Hofmeyr: laureate of the Queen Elizabeth International Composition Competition, entitled Spokewals / Phantom Waltz and Notturno Elegiaco. Spokewals / Phantom Waltz is a challenging work where musicians simultaneously play, sing and speak.

A reworked edition for chamber orchestra of the original string quartet for piano and soprano, Liedere op Boesman-verse, by revered South African composer, Stefans Grové, will also be performed. To commemorate the centenary of composer Benjamin Britten this year, Cantus in Memoriam of Benjamin Britten by Arvo Pärt is also included in the programme.

After participating at the festival in St Petersburg, the ensemble will depart for a two-day visit to Moscow where the OSMC will perform an ’All South African’ programme.
