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.

During a direct conversation with the South African ambassador to Japan, Mr Gert Grobler, today, the University of the Free State (UFS) expressed its compassion and solidarity with the people of Japan. The university also stated that it intended to support the country and its citizens in various ways.

This came after Japan was plunged into chaos the past week as a result of various earthquakes and consequential disasters. Mr Grobler, who participated in the conversation via Skype from Tokyo, welcomed this talk initiative initiated by Mr Rudi Buys, Dean: Student Affairs, and the Interim Student Committee (ISC). The talks formed part of a series of initiatives launched by students to promote solidarity with Japan, and which includes fund-raising projects and awareness campaigns.

Mr Grobler expressed his appreciation for the initiative: “The initiative by the UFS is greatly appreciated, and I shall do anything to promote partnerships between the UFS and Japan, particularly in collaboration with the ambassador for Japan in South Africa. The solidarity project is essential, because this is the worst crisis Japan has ever experienced in its history.”

In solidarity with Japan, the Student Committee envisages a mass march on Thursday, 17 March 2011 by means of which students will declare their unanimity with Japan and their support of human rights.

Prof. Jonathan Jansen, UFS Vice-Chancellor and Rector, also promised to send a message of support directly to the Japanese embassy in Pretoria, as well as extending a hand of support to Japanese universities in order to become part of discussions on how to render assistance, while making plans for students to visit the respective countries and share their experiences first-hand.

Mr Buys informed the ambassador that the university would support the rescue teams, which are departing for Japan in response to a request by Mr Grobler, by means of manpower. In response to this, Mr Grobler, a Kovsie alumnus, welcomed this token of compassion and offer of assistance. “I am excited to see that South Africa cares so much for Japan.”
