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.

State of our campuses: UFS Bloemfontein and South Campuses closed on Tuesday 20 September 2016
2016-09-19

After much consideration, the senior leadership of the University of the Free State (UFS) decided to close the Bloemfontein and South Campuses on Tuesday 20 September 2016.

Bloemfontein Campus:
No academic and administrative services will be available and no lectures and/or tests will take place.

The decision comes after all academic activities were suspended this afternoon because of a growing unease on campus and disruption of some academic activities by groups of students resulting from this morning’s announcement on tuition fees by the Minister of Higher Education and Training, Dr Blade Nzimande.

The closing of the campus will afford an opportunity to the senior leadership to further engage with the Student Representative Council (SRC).

South Campus:
Because of problems with bus transport from the Bloemfontein Campus to the South Campus, no academic services will be available tomorrow. No lectures and/or tests will therefore take place. Administrative services will, however, continue, and staff on the South Campus have to report for work.

Qwaqwa Campus:
Academic and administrative services on the Qwaqwa Campus will continue as normal tomorrow.

Information about the situation on the campuses will be shared as and when it becomes available during the course of tomorrow.
