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.

Protest actions planned for 12-14 March 2008

2008-03-13

Three protest actions will take place on the Main Campus of the University of the Free State (UFS) in Bloemfontein this week.

Although the interim court interdict granted to the UFS on 6 March 2008 is still in force, permission for the three protests was granted by the Mangaung Local Municipality and the court, in the presence of the university lawyer. Strict conditions have been set for these protest actions.

The UFS management respects the right to peaceful protest and also shares the sentiment of the protesters regarding the reprehensible Reitz video. However, strict conditions have been set for these protest actions as students are writing tests and the normal academic activities should not be disrupted.

Already the first picket protest took place today, Wednesday, 12 March 2008, by about 300 Satawu and Nehawu members. This was not a march and no memorandum was handed over.

On Thursday, 13 March 2008, Nehawu will again picket in front of the Main Building from 13:00 to 14:00. This event must be peaceful. This too is not a march and no memorandum will be handed over.

On Friday, 14 March 2008, a march of Cosatu and Nehawu will take place, starting in the city centre. The march will enter through the Nelson Mandela Drive gate and will enter the campus grounds.

However, it will be limited to the incoming lane of Chancellors Avenue from the Main Gate to the crossing with Alumni Avenue (in front of the Odeion building). Speeches will be made and a memorandum will be handed over.

It is expected that the march will reach the campus at approximately 10:00 and from then the Nelson Mandela Gate to the UFS will be closed for all traffic. The march must end by 14:00. The marchers will return to the city centre and may cause a traffic problem in Nelson Mandela Drive.

The South African Police Service (SAPS) and the UFS’s Protection Services Division will monitor all these actions. Staff, students and visitors to the campus are kindly requested to use alternative gates to the Nelson Mandela entrance on Friday. Academic activities will continue as normal this week.
