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.

Disaster risk management centre of the UFS serves on UN specialist committee

The Director of the Disaster Management Training and Education Centre (DiMTEC) at the University of the Free State, Dr Andries Jordaan, has been invited to serve on a UN special committee by the Secretary-General of the United Nations.

Dr Jordaan took part in the Expert Workshop on Climate Resilience in Geneva, Switzerland, on 22-23 June 2015.

In preparation for COP 21, which takes place later this year in Paris, the United Nations must draw up a situation report for a universal climate agreement between all the world’s nations. In order to advise the United Nations and the Secretary-General, and to prepare for the UN’s resilience initiative that will be launched during this important international gathering, a small  team of approximately 20 experts and scientists from all over the world have been chosen to review the concept of the project. This group of experts will help to revise the original concept for the project.

According to Dr Jordaan, the Sectretary-General of the UN will be launching a ‘resilience initiative’ that is aimed at promoting resilience in climate-related risks.

Jordaan says it is an honour for him to represent the UFS and DiMTEC on such a specialist committee. “For me, it is recognition of the contribution we make in Africa and the world to disaster risk and climate adaptation,” he says.

DiMTEC is proud to be at the forefront of disaster management training in Africa. The centre has close ties with institutions of the United Nations, such as UNU-EHS, UNU-Flores UNOOSA, UNSPIDER, UNEASCO, UNEP, UNCCD, UNISDR and UNDP, among others.

DiMTEC strives to inform the public about disaster risk reduction through education. The centre’s master’s and post-graduate degrees in disaster management, as well as short courses and research, are of the highest standard.
