Bloemfontein Campus Solar Farm

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

Producers to save thousands with routine marketing strategies, says UFS researcher

Using derivative markets as a marketing strategy can be complicated for farmers. The producers tend to use high risk strategies which include the selling of the crop on the cash market after harvest; whilst the high market risks require innovative strategies including the use of futures and options as traded on the South African Futures Exchange (SAFEX).

Using these innovative strategies are mostly due to a lack of interest and knowledge of the market. The purpose of the research conducted by Dr Dirk Strydom and Manfred Venter from the Department of Agricultural Economics at the University of the Free State (UFS) is to examine whether the adoption of a basic routine strategy is better than adopting no strategy at all.

The research illustrates that by using a Stochastic Efficiency with Respect to a Function (SERF) and Cumulative Distribution Function (CDF) that the use of five basic routine marketing strategies can be more rewarding. These basic strategies are:
• Put (plant time)
• Twelve-segment pricing
• Three-segment pricing
• Put (pollination)(Critical Moment in production/marketing process), and
• Pricing during pollination phase.

These strategies can be adopted by farmers without an in-depth understanding of the market and market-signals. Farmers can save as much as R1.6 million per year on a 2000ha farm with an average yield.

The results obtained from the research illustrate that each strategy is different for each crop. Very important is that the hedging strategies are better than no hedging strategy at all.

This research can also be applicable to the procurement side of the supply chain.

Maize milling firms use complex procurement strategies to procure their raw materials, or sometimes no strategy at all. In this research, basic routine price hedging strategies were analysed as part of the procurement of white maize over a ten-year period ranging from 2002–2012. Part of the pricing strategies used to procure white maize over the period of ten years were a call and min/max strategy. These strategies were compared to the baseline spot market. The data was obtained from the Johannesburg Stock Exchange’s Agricultural Products Division better known as SAFEX.

The results obtained from the research prove that by using basic routine price-hedging strategies to procure white maize, it is more beneficial to do so than by procuring from the spot market (a difference of more than R100 mil).

Thus, it can be concluded that it is not always necessary to use a complex method of sourcing white maize through SAFEX, to be efficient. By implementing a basic routine price hedging strategy year on year it can be better than procuring from the spot market.
