Weathering the winter with energy efficiency

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.

SRC elections continue despite illegal protests on UFS Main Campus

2011-08-17

After today’s (17 August 2011) illegal protest by about 150 demonstrators from outside the university in front of the Main Building on our Bloemfontein Campus, Mr Rudi Buys, Dean: Student Affairs, said the elections for a Representative Student Council still continues. “Student Council candidates will continue with their campaign and, as agreed, no external politics will be allowed in the elections.”

Student leaders have expressed their frustration with the outside groups who interfere with processes on campus.

The UFS was the target of a group of people from outside the university who protested in front of the Main Building. The group, armed with sticks and bricks, had no clear demands other than that the UFS Council should be dissolved and management fired. It appears that some of the outsiders – from places such as Welkom and Kroonstad – did not know what they came to do at the university.

No students were involved in the protest action.

During the demonstration, the police and campus security were deployed and some of the demonstrators were arrested.

Prof. Jonathan Jansen, Vice-Chancellor and Rector said: “The UFS is worried about the thuggish behaviour by outside groups invading the university campus. An urgent interdict has been obtained and any further invasions by outside groups will lead to arrest.”

The illegal process had no impact on the academic programme at the university. Everything continues as normal.
