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.

UFS awarded tenders worth R22,5 million for Maths and Science teacher-training
2010-03-17

The Centre for Education Development (CED) at the University of the Free State (UFS) has received tenders worth about R22,5 million over the past two years from four provinces to train Mathematics and Science teachers from underperforming schools.

The CED has received tenders from the following provincial departments of education: Free State, Northern Cape, North West and Mpumalanga.

“The centre has a good reputation for the training of teachers in these disciplines and has been involved with the upgrading of Maths and Science teachers for at least 15 years,” said Prof. Daniella Coetzee, Director of the CED.

It is currently busy with the training of North West teachers after being awarded a R13,5 million tender by the Province as part of its quest to improve pass rates in Mathematics and Natural and Physical Sciences in underperforming schools.

“The tender is for the upgrading of the knowledge and methodology of teachers for Mathematics and Natural and Physical Science, as well as the upgrading of the knowledge of subject specialists in the North West Province,” said Prof. Coetzee.

For this project the centre trains 1 000 teachers and 90 subject specialists from underperforming schools over a period of three years.

The programme commenced in February this year with a baseline assessment of the teachers to determine knowledge and methodology gaps upon which to focus in the training.

“After the programme has been completed we will also do a post-assessment to see if there had been progress,” she said.

The training is offered only on Saturdays at Vryburg, Klerksdorp, Makapanstad, Brits and Zeerust and is presented by lecturers from the CED as well as selected and trained tutors from the North West province.

“We have successfully completed another Maths, Science and Technology project for the North West Department of Education. We have also completed similar projects for the Northern Cape and one for the Free State Department of Education,” she said.

These completed projects entailed formal qualifications (Advanced Certificate in Education) in Maths, Science and Technology and were worth in excess of R5 million.

The CED has just been recently awarded yet another tender in excess of R4 million over a period of two years by the Mpumalanga Department of Education.

Prof. Coetzee had the following to say about the CED being the preferred choice of these provincial Departments of Education: “It has to do with the fact that the CED has been performing well with the upgrading of teachers. It has proven itself as a leader in the in-service training of Maths and Science teachers in South Africa.”
