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.

Prof Heidi Hudson, director of the Centre for Africa Studies at the University of the Free State, was recently appointed by the President of the International Studies Association (ISA) to serve on the Committee on the Status of Women from March 2016 to April 2018. 

Representing over 100 countries, ISA has more than 6 500 members in North America and internationally, and is the most respected and widely-known scholarly association in the field of International Studies. 

She anticipates that her role on the committee will complement her research interests in feminist security theory and practice in Africa. “I am looking forward to playing a part in the advancement of southern scholars, and the promotion of their voice in global academe.”   

Prior to Professor Hudson’s appointment, she served as a member of the executive of the Feminist Theory and Gender Studies (FTGS) Section of ISA.

Representing women of the world in academia

The Committee on the Status of Women has the task of reviewing the status of women in the profession, and making recommendations to the president and the Governing Council of ISA on ways of tracking and increasing the status and visibility of women in the profession.

“Some of the goals of the committee for the 2014 to 2016 period include reaching out to women scholars in the global south; creating an ISA networking website for women scholars; and surveying perceptions of the international relations climate and its needs,” said Prof Hudson. It is also responsible for “tracking gender balance within ISA and its journals, and supporting ISA regions in fulfilling the mission of the Committee on the Status of Women,” she added.

Connecting scholars globally since 1959

The ISA has been the premier organisation for connecting scholars and practitioners in fields of international studies, and promoting research and education. ISA cooperates with 57 international studies organisations in more than 30 countries, is a member of the International Social Science Council, and enjoys non-governmental consultative status at the United Nations.

Prof Hudson’s research interests concentrate on discursive and material gender deficits of liberal peacebuilding in the post colony, amongst other subjects. She is also co-editor of International Feminist Journal of Politics.
