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.

Leah Tutu - from a humble heritage to a matriarch of devotion

Leah Tutu Symposium: YouTube video

There are treasures in life, but owners are few
Of money and power to buy things brand new
Yet you can be wealthy and feel regal too,
If you will just look for the treasures in you …

The joy and the laughter, the smile that you bring;
The heart unafraid to love and to sing;
The hand always willing to help those in need;
Ones quick to reach out, to labour and feed.

So thank you for sharing these great gifts inside;
The caring, the cheering, the hug when one cried.
Thanks for the energy, encouragement too,
And thank you for sharing the treasures in you. (Author unknown)

With these words, Thandeka Tutu-Gxashe embodied the celebration in honour of her mother, Leah Tutu.

On Thursday 17 October 2013, the Annual Intercontinental Leah Tutu Symposium was launched at the UFS’ Bloemfontein Campus. Dignitaries and students alike flocked to the Centenary Hall where friends and family shared their immense love and respect for Ms Tutu.

Approaching the podium, Eunice Dhadhla (co-founder with Ms Tutu of the Domestic Workers Union) started humming and in an instant the audience had risen to their feet and the words “My mother was a kitchen girl. My father was a garden boy. That’s why I’m a unionist”, reverberated through the hall.

“I am what I am today because of her,” Dhadhla said of Ms Tutu. They have walked a long hard road together to ultimately unite domestic workers across the globe. Stretching her small body to its full length, Dhadhla imparted one of the most valuable lessons she has learned from Ms Tutu, “Stop crawling, stand up and walk for yourself.”

As soon as Dr Sindiwe Magona – acclaimed writer and poet – ascended the stage, her energy rushed across the room with electrifying intensity. Her high regard for Ms Tutu as public icon as well as a mother, wife and friend, was palpable. Belting out line after line of a poem she wrote especially for Ms Tutu, the audience echoed their agreement in a mutual exchange.
No sooner were they seated, than Archbishop Desmond Tutu and Prof Jonathan Jansen had the crowd roaring with laughter. Archbishop Tutu’s familiar chuckle peppered his story of how he came to propose to his wife. It was clear, though, how much he reveres Ms Tutu’s presence in his life. With enormous awe, he revealed her innate power, specifically during difficult times in our country’s past – from weathering death threats against her husband to public humiliation.

But despite adversity and heartache, in front of the Centenary Hall, this matriarch stood up and beamed joy into everyone present.
