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.

In support of building a more equitable and prosperous Africa, and in response to the plight of students who lack financial aid at universities across the country, Absa Bank handed over a cheque of R10 million to the University of the Free State (UFS) at a ceremony held on the Bloemfontein Campus on 13 June 2017 by the office of Institutional Advancement. The allocation of these funds will assist students who meet the bursary programme criteria (proven financial need, students who are from households with a combined income of less than R1 million per annum, with an academic average of 55% or higher).

Corporate and higher education collaborate
Speaking at the event, Rector and Vice-Chancellor of the UFS Prof Francis Petersen highlighted the important role corporates play in collaborating with educational institutions to help support future professionals who are the future builders of the economy and will later lead industry. “Absa and the UFS enjoy a good relationship and it is our hope that this bursary programme will grow from strength to strength,” he said.

In 2016 alone, Absa Bank disbursed R12 million towards settling outstanding fees for 439 students in four faculties of the UFS. In 2017 the funds will be allocated similarly to cover financial needs of qualifying students. Mr Bertie Smith, Absa Management Executive: Central Region said: “The university plays an important role in building future leaders and Absa’s strategy of shared growth supports the focus on education.”

Responding to a greater socioeconomic need
The event was attended by staff of the UFS and delegates from the Absa group, as well as students who were beneficiaries of the Absa Bursary Fund in 2016. Mr Fikemini Dlamini, Absa Head: Public Sector Business Banking, said the bursary programme was born out of the growing need to fund and develop the education of young people, and is a response to the outcry from students across the country in the “Fees Must Fall” movement. He said: “Educating one young person has a knock-on effect that has the potential to alleviate poverty in many families and communities around us.”
