UFS installs solar plants on all campuses, bolstering renewable energy amid continuing power cuts

Bloemfontein Campus Solar Farm — The solar plant on the UFS’s Bloemfontein Campus, part of the university’s commitment to combatting loadshedding and embracing sustainable energy.

The University of the Free State (UFS) has installed solar plants across its three campuses.

The university says this is in response to the call for urgent solutions to loadshedding and the promotion of environmentally sustainable, cleaner, and renewable energy solutions.

Nicolaas Esterhuysen, Director of Engineering Services at UFS University Estates, said,

“The PV (photovoltaic) systems are grid-tied without storage to ensure maximum benefits and faster payback periods.”

Esterhuysen said the UFS has saved up to R32,5 million since the first solar plant was commissioned in 2017 to help the UFS reduce the impact of loadshedding and its carbon footprint and energy costs. “This will substantially increase this year with the commissioning of two large new ground-mounted solar plants on the Bloemfontein Campus,” he said.

“The microgrid installation on Qwaqwa Campus is one of the biggest solar diesel hybrid systems installed in South Africa. It allows us to keep the campus running despite excessive power interruptions.”

The UFS is currently embarking on research as part of the Grid-related Research Group (GRRP) under the Interdisciplinary Centre for Digital Futures (ICDF) to also help staff and students with understanding renewable energy and sustainability.

Esterhuysen said the plants are further evidence of the UFS’s commitment to renewable and energy saving solutions. “It is our flagship project, but our focus is also on energy saving initiatives – to ensure we are becoming more energy efficient and eliminate energy wastage. We have plans for expansion on all campuses. Some of the highlights are an off-grid solution for the new student centre at Qwaqwa Campus and to make South Campus a self-sustaining campus.”

The installed grid-tied system solar plants are operating without batteries on all three campuses, giving the university an optimal configuration between capital cost and payback period.

The energy generated at the solar plants:

Bloemfontein Campus – 3688 kWp

Qwaqwa Campus – 918 kWp

South Campus – 759 kWp

Paradys – 125 kWp

Water use on campus

2015-12-14

Report water wastage on the campuses.

High temperatures and the fact that no rain was falling, puts pressure on the existing water supply. The Free State is one of the most arid areas in the country, and the province was also declared a drought area by the government.

It is therefore very important that the UFS community will use water sparingly – both where you live and in the workplace.

Report water wastage on the campuses by sending an email to news@ufs.ac.za or phone 051 401 3422.

Tips to use water sparingly in the workplace:
- Set up an inventory regarding water use and identifiable water management goals in your department. Control this to indicate progress.
- Keep a bottle of tap water in the fridge to avoid running the tap until the water is cold.
- Fill the kettle with water according to your needs.
- Sweep paving with a broom instead of washing it with water.
- Apply mulch to your garden, as it can reduce water use by up to 70%.
- Don’t rinse glasses and other dishes under running water. Plug the sink and reuse the water in the garden.
- Where possible, recycle water. Support projects making use of recycled water.
- When waiting for hot water to come out of the tap, place a bucket under the tap so that the cold water can be used later.
- Don’t let water run wild. Make sure all taps in the kitchen or bathroom are closed when leaving the office/residence.

Tips to use water sparingly at home:
- Showering can use up to 20 litres of water per minute. Take short showers, less than 5 minutes.
- Turn the tap off between washing your face, brushing your teeth or shaving
- Ensure that you have a full load of washing when using the washing machine.
