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.

Measures to ensure safer campuses are investigated
2010-04-16

The safety of students, lecturers and staff of the University of the Free State (UFS) is of the utmost importance for the management of this institution and deliberations are continuously taking place on what can be done to improve the levels of safety of the respective campuses in Bloemfontein and Qwaqwa.

A set of recommendations was recently tabled by our rectorate that make provision for various measures for safer campuses. According to Prof. Niel Viljoen, Vice-Rector: Operations at the UFS, attention will urgently be paid to the following recommendations:

  • The instalment of alarm systems, linked to the central security control room, in all buildings on the respective campuses.
  • The instalment of “panic systems” in strategic places in buildings.
  • Where possible, better admission control to buildings, especially office blocks.
  • Better management en integration of contracted-in security workers.
  • Enhancement/upgrading and better monitoring of the security control room and sharpening of reaction times in cases of emergency.
  • Repair and maintenance of the current border fencing.
  • A survey was once again done of all the so-called “dark spots” on campus and the instalment more effective lighting are currently in progress.
  • Safeguarding of footways and parking areas by means of cameras and panic systems that will be monitored 24 hours a day, seven days a week.
  • Better and more visible patrolling of the pedestrian walkways and campuses.

Regular and structured feedback regarding the safety situation at all campuses shall also be done.

According to Prof. Viljoen the following recommendations shall also be investigated further:

- The feasibility of the “closing” of the campus, especially in terms of transport implications, costs and effectiveness.
- The possible closing of the small pedestrian gates in order to channel pedestrian traffic through the existing and manned gates.
- The feasibility of the compulsory wearing of ID cards by all personnel, students and temporary workers.
