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.

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.”
