UFS campuses are transforming into research instruments while simultaneously improving campus operations through the Smart Grid initiative.

Imagine living in a smart home. Imagine monitoring your household’s electricity usage via an integrated system that would notify you of your daily electricity use, peak usage times, and tariffs and consumption at the location of the house. As a user, you would be able to take advantage of such information in order to manage your resources in a more efficient manner. This is just one example of what a Smart Grid can do.

The University of the Free State’s (UFS) Faculty of Natural and Agricultural Sciences has teamed up with the Department of University Estates to drive our very own Smart Grid initiative that is transforming the university’s power network into one with full control and monitoring. “A Smart Grid allows for resource optimisation and asset protection, especially in times like these,” said Nicolaas Esterhuysen, Director of Engineering Services. 

Why is it important for our university to have a Smart Grid?
Dr Jacques Maritz, Lecturer of Engineering Sciences at the Faculty, considers a Smart Grid the natural evolution of power grids in the era of Big Data, IoT and Machine Learning. Resources such as electricity, water and steam can now be monitored and controlled to promote savings and the protection of valuable infrastructure. “Aiming towards Smart Grid status, the UFS will improve resource service-delivery to its staff and students, while sculpting a digital twin of its campus’s power grid, consumer network and resource generators,” he added.
  
How will a Smart Grid improve student success?
The integrity, sustainability and continuous supply of energy directly affects the academic project on all three campuses. The implementation of a Smart Grid could allow improved service delivery and reaction time when any utility is interrupted, as well as maintaining the valuable infrastructure that serves the UFS community.

In what way does a Smart Grid improve the lives of staff members?
According to Dr Maritz  and Esterhuysen: “A Smart Grid will support staff to perform their teaching and research duties in a seamless manner, continuously optimising the energy that they consume to enable full comfort and reliability in energy supply, whilst simultaneously generating savings in energy and preventing wastage.”

The UFS already boasts most of the fundamental building blocks associated with the Smart Grid initiative, especially focusing on monitoring, grid protection, centralised and decentralised solar PV generation and software platforms to serve all these domains. However, to integrate all of these domains into one digital real-time paradigm will be a first for the UFS.

Some examples of the UFS smart grid applications currently in practice
Real-time remote monitoring and control that focuses on the following:
- We are able to detect power outages and don’t have to rely on customer complaints. This enables faster response time and fault identification, thus less downtime and an increase in reliability;
- Solar plant generation; 
- Monitoring our standby generation fleet; 
Identifying usage patterns and saving thereof;
Benchmarking buildings in terms of application usage, area or occupancy to determine energy efficiency and identify savings; and condition-based preventive maintenance that will increase reliability while saving costs.

What were South Africans left with after The Spear? More importantly, what did we learn from The Spear?

These were the issues discussed at a seminar, Beyond the Spear, on the controversial Brett Murray painting at the Bloemfontein Campus of the University of the Free State (UFS) on Monday 13 August 2012.

The university hosted this seminar, Beyond the Spear, in conjunction with acclaimed journalists, to look deeper into the lessons that South Africans learnt from this painting and the reaction from the public and politicians following soon after it went on display at the Goodman Gallery in Johannesburg.

The four panellists, Mr Justice Malala (political analyst, journalist and host of the news show, The Justice Factor), Mr Nic Dawes (editor in chief of Mail & Guardian), Mr Max du Preez (investigative journalist and political columnist) and Ms Ferial Haffajee (editor of City Press), all presented their views and experiences on the public’s perceptions of this artwork.

In his opening remarks, Prof. Jonathan Jansen, Vice-Chancellor and Rector, said the purpose of the seminar was to help us make sense of what happened. Prof. Jansen also chaired this seminar.

“This being South Africa, there will be more ‘Spears’. More public crises will unfold that divide the nation and that will stir the emotions. We need to understand what happened so that we are better prepared to deal with the coming ‘Spears’.”

Issues on leadership, South Africa’s hurtful past and the freedom of expression were some of the topics raised by the panellists.

“This has taught us that South Africans – especially the older generation – still need to vent their anger… White South Africa must be patient and allow black citizens to shout at them,” said Mr Du Preez. He warned that this anger should serve a constructive purpose. In reaction to a question if Brett Murray did not disrespect Pres. Jacob Zuma’s dignity with his controversial painting, he said that this painting was “…rude and disrespectful.”

“It was meant to be. It was not honouring him.” He said that politicians will do anything, including messing with the country’s stability, to further their own interests. “From now on we need to be far more alert, far more cynical about our politicians.”

Mr Dawes shared his experience and said that the debates around The Spear were very painful considering where the nation has come from. He said the painting opened up painful pasts and difficult spaces. “It is up to the media to open up these difficult spaces.” He said the painting also brought up questions of how South Africans deal and live with pain. “South Africa must live with its past. The debate should now be how to preserve space for the country’s ghosts and how its citizens could get the resilience to deal with it.”

Ms Haffajee, who was caught in the crossfire between freedom of expression and human dignity and who refused to remove a picture of the painting from the City Press website, said that the media was viciously played by politicians.

“This had shown that achieving freedom took many lives, but it took very little to kill it.” She said The Spear is art that it is part of a rich cultural heritage of protest art.

Mr Malala said with the debates around The Spear painting, something died in South Africa. “The debate was taken away from us. We let politicians get to us.”

After the panellists delivered their presentations, Prof. Jansen led a discussion session between the audience and the panellists.
