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.

SRC raises over R1 million for UFS underprivileged students

2016-01-18

R1.2 million has been raised by the University of the Free State’s (UFS) Student Representative Council (SRC) under the Right to Learn (R2L) campaign banner.

The SRC launched the R2L campaign on 30 October 2015,following the first wave of the #FeesMustFall movement protests against a proposed increase in tuition fees. The campaign was initiated to ensure that academically-deserving underprivileged students do not have to bear the brunt of deregistration, food insecurity, and the lack of textbooks.

To date, the student leaders have taken it upon themselves to appeal to lecturers, businesses, the community, and students alike to support its campaign. Each SRC member pledged R500 from their own purses when the campaign was launched.

Looking back at the #FeesMustFall movement

To the #FeesMustFall movement, which had gained momentum and resulted in a shutdown of many campuses across the country, President Jacob Zuma responded with a statement announcing a 0 % increase.

At the launch of the campaign, Lindokuhle Ntuli, the UFS SRC President, made a commitment to source financial aid for needy students.

“Even though the president said no fees will increase this year, we are still faced with the same challenges. No students who qualify should be de-registered this year. It is up to us to raise funds for the poor students to ensure that they get their right to education.”

Forward to the future: #AccessMustRise

By 4 April 2016, the SRC’s goal is to accumulate financial relief worth R5 million to counter the growing financial aid demand.

Given that more South Africans are extending a helping hand, the SRC President is adamant about gathering the sponsorships in two months. “It is possible if we push to market the campaign to gather R4.8 million,” said Ntuli.
