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.

Kovsie student to participate in G8 2013 Summit
2013-06-06

A Kovsie student is heading to London to attend the June G8 2013 Youth Summit. Tumelo Moreri is part of a chosen few who will walk among world class leaders as a delegate of the African Union.

The summit provides a platform for young leaders where they are able to collectively voice their opinions. It also gives them the opportunity to gain valuable insights on international diplomacy in order to tackle 21st century challenges head on.

The African Union delegation, of which Tumelo is part, includes representatives from the Democratic Republic of Congo, Botswana, Kenya, South Africa, Nigeria and Zimbabwe. It consists of a Head of Government, Sherpa, Press Secretary, Minister of Trade and Industry, Minister of Finance, Minister of Justice, Minister of Foreign Affairs, Minister of Energy and Climate Change, Minister of Development, and Minister of Defence. They are responsible for developing and negotiating position papers with regards to the various ministerial positions.

Tumelo Moreri is a co-founder of Tomorrow’s Leaders Today in her home country, Botswana. She is currently the International Affairs Officer of the Student Representative Council (SRC) at the Bloemfontein Campus. “The highlight for me is the fact that I am representing Africa. Africa’s voice will get to be heard through us,” says Moreri. “I see this as a huge opportunity to strive to make a contribution towards Africa and finding solutions unique to her problems. This will be a stepping stone to effecting change. This learning curve will shape and influence global discourse.”
