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.

Private screening of Soft Vengeance: Albie Sachs and the New South Africa by Abby Ginzberg
2014-03-26

Soft Vengeance: Albie Sachs and the New South Africa, a film by Abby Ginzberg, was recently screened at the Odeion. The film is based on the life of Albie Sachs as lawyer, political activist, writer and art lover. 

Judge Sachs’ career in human rights activism started while studying law at the University of Cape Town. In 1955 he attended the Congress of the People at Kliptown where the Freedom Charter was adopted. At age 23 he started to practice as an advocate at the Cape Town Bar and defended people charged under the racial statutes and security laws of apartheid.

The film captures his tough life experiences, ranging from political imprisonment and torture, life in exile, to being a judge in the Constitutional Court and his ability to communicate human dimensions about legal matters. This same quality is highlighted in his judicial opinions on topics such as capital punishment, the rights of homeless people and same-sex marriages.

The screening of the film was hosted by the Vice-Chancellor and Rector, Prof Jonathan Jansen, with the Institute for Reconciliation and Social Justice and the Archive for Contemporary Affairs.

Judge Albie Sachs attended the screening and was be available to answer questions afterwards.
