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.

Co-architect of peace and reconciliation in Northern Ireland to present Annual Reconciliation Lecture today
2015-03-03

Colm McGivern, Director of the British Council in South Africa

To emphasise the University of the Free State’s Human Project, the UFS has positioned itself as an institution that is recognised across the world not only for excellence in academic achievement, but also in human reconciliation. The Annual Reconciliation Lecture, whose organising committee is chaired by Prof Pumla Gobodo-Madikizela, is a unique and major initiative to enhance this important vision of our university.

This year, Colm McGivern, Director of the British Council in South Africa, will present the Fourth Annual Reconciliation Lecture at the Centenary Hall on Thursday 5 March 2015.

Colm McGivern was brought up in Northern Ireland at the height of the conflict that has come to be known as the ‘Troubles.’ His early experiences of conflict, sectarianism, and living in a divided society have driven his career, and his personal commitment to peace-building and promoting reconciliation.  He was a student leader at Queen’s University in Belfast during the time of the first IRA Ceasefires in the 1990s, and then worked in the Higher and Further Education sectors, and at a community level with peace-building groups across Northern Ireland and internationally. He was Director of the British Council in Northern Ireland for four years and, in that role, facilitated discussions between divided communities before and during the Ceasefires and Peace Process, with a particular focus on bringing young people together across Ireland.

In his role as Director of the British Council, McGivern has created thousands of cultural and educational connections between the UK and SA. Every year, he ensures that young South Africans can get access to educational and cultural opportunities that are life-changing while deepening their connection with the UK.

A highlight of this year’s lecture will be a performance by musicians from the Odeion School of Music, Tumi Ntantiso (soprano), Bertha Menyatso (mezzo-soprano), Malefetsane Mofokeng (baritone), and Cezarre Strydom (piano). They will be performing works from ‘Tales of Hoffmann’ by Jacques Offenbach, among others.

Members of the public and media are welcome.
