Weathering the winter with energy efficiency

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.

Rasool lauds our university

2011-10-24

At the dinner at the residence of the South African Ambassador to the USA, Mr Ebrahim Rasool, were, from the left: Prof. Debra Stewart, President of the Council of Graduate Schools in the USA; South African Ambassador, Mr Rasool; Prof. Jansen; and Prof. Molly Corbett Broad, President of the American Council on Education (ACE).

The Ambassador for South Africa to the United States of America (USA), Mr Ebrahim Rasool, recently hosted Prof. Jonathan Jansen, Vice-Chancellor and Rector of our university and a group of representatives from major science councils, foundations and universities at his home in Washington DC. Our university is the first South African university to be hosted at the official home of the Ambassador.

“The University of the Free State has shown South Africa and the world how to work with the past and how to make the past work for them. “You are a thought leader who had the privilege not to be comfortable with your own ideas of history; you understood the need to change and embraced it. You have moved the fastest towards racial and human togetherness of all the South African universities,” Mr Rasool said.

Prof. Jansen responded by saying that Africa needed strong academic universities and that had to be the focus of tertiary institutions across the continent. “We must create opportunities for people to be together and to learn from each other. The UFS is an experiment of human togetherness – and this experiment is taking off,” he said.

During his visit to the USA, Prof. Jansen also discussed research partnerships and new placements for UFS staff and students through exchange visits.
