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.

Sarah Shannon at the Paralympic Games in Beijing

 

Sarah Shannon, a second-year student in the Postgraduate Certificate in Education, has been involved in disability sport on national level for the past 12 years. Sarah has cerebral palsy.

In 1996 she participated at the South African National Championships for the physically disabled for the first time, entering for several sporting codes and winning five gold medals. In swimming she participates in the S3 class together with other swimmers that have comparable abilities to hers.

In 1997 she decided to focus on swimming competitively. She participated in her first national championships for swimming that year. After that (1998) she represented South Africa on international level at the International Paralympic Committee’s (IPC) Swimming World Championships in New Zealand where she ended 4th in the 50m backstroke and 7th in both the 50m and 100m freestyle in her class.

In 1999 she represented South Africa in Johannesburg at the 7th All Africa Games and won a silver medal for the 50m freestyle and a bronze medal for the 100m freestyle.

In 2000 she was part of the South African team at the Sydney Paralympic Games where she reached the finals and finished 7th in the 50m backstroke and 8th in the 50m freestyle. Northern-KwaZulu-Natal also awarded her the Junior Sportswoman of the Year award in 2001. In 2002 she participated at the South African Senior National swimming championships for KwaZulu-Natal in the multi-disability category.

In 2005 she completed the Midmar Mile. She also represented South Africa at the world championships for athletes with cerebral palsy in Boston in the United States of America. She won two gold medals for respectively the 50m freestyle and the 50m backstroke and two silver medals in the 100m and 200m freestyle. She was also nominated to represent South Africa as athlete’s representative on the world committee of CPISRA (Cerebral Palsy International Sports and Recreation Association). In this year Sarah also received the KwaZulu-Natal Premier’s Sportswoman with a disability award of the year.

In 2006 she qualified for the IPC world championships but could not attend.

In 2007 she represented South Africa once more at the Visa Paralympic World Cup in Manchester in the United Kingdom where she broke the South African record in the 50m backstroke, finishing 7th in the 50m freestyle and 6th in the 50m backstroke.

She was also part of the very successful Team South Africa to the Paralympic Games in Beijing. She reached the finals in both the 50m backstroke and 50m freestyle. She finished 7th in the 50m freestyle and 6th in the 50m backstroke in personal best times for both events. She has been participating in the able bodied South African National Swimming Championships since 2002. She is currently ranked 2nd in the world for short course items and 11th for the long course items. She is truly our best swimmer in the S3 class.
