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.

UFS staff to get a minimum of 4,71 percent salary increase
2005-11-25

The University of the Free State (UFS) management and trade unions have agreed on a minimum of 4,71 percent salary increase for 2006 as well as a once-off non-pensionable bonus of R1200 payable in December 2005.

The agreement was signed today by representatives of the UFS management and the trade unions, UVPERSU and NEHAWU, in Bloemfontein.

Prof Niel Viljoen, Chief Director: Operations at the UFS and chairperson of the UFS Council’s representatives, and Prof Johan Grobbelaar, chairperson of the joint Union Forum, said: “The bonus is payable in December 2005 in recognition of the role that staff played during the year to promote the UFS as a university of excellence.”

He said the intention is to pass the maximum benefit possible on to staff without exceeding the limits of financial sustainability of the institution.
For this reason the negotiating parties reaffirmed their commitment to the Multiple-year Income-related Remuneration Improvement Model used as a framework for negotiations.

Proff Viljoen and Prof Grobbelaar said one of the factors that influence the model and therefore the negotiations is the level of subsidy the UFS receives from the government.

“As the state subsidy level is unfortunately not yet known, remuneration could vary several percentage points between a window of 4,71 and 5,5 percent. Should the state subsidy be such that the increase would fall outside this window then the parties will renegotiate.”

Proff  Viljoen and Prof Grobbelaar said the R1200 bonus is payable to staff members who were in the employ of the UFS on UFS conditions of service on 21 November 2005 and who assumed duties before 1 October 2005. There are however some exceptions.

The agreement signed today also provides for restructuring funds of R752 000 to address partial backlogs in support services, including an increase in the medical allowance of 640 staff members.

The implementation date for the salary adjustment is 1 January 2006, but could be implemented on a later date due to logistical arrangements.

Proff Viljoen and Prof Grobbelaar said the UFS and unions could reach an agreement despite the declining phase in income and the generally more difficult financial environment in which universities operate.

Prof Grobbelaar said salary negotiations are never easy, but the model is an important tool. The model made it possible to tie up salary negotiations for November 2006. “This is unique for any higher education institution.”
