ENERGY EFFICIENCY
Energy efficiency key to business growth during power stresses

Companies would need to grow without using more power, and organisations that did not take the energy situation seriously would not survive, said South African Association of Energy Efficiency (SAAEE) president LJ Grobler recently.

Energy Minister Dipuo Peters added that electricity consumers had “been lulled into a sense of comfort by the economic downturn”, and seemed to forget that the reserve margin was still very low.
Eskom spokesperson Andrew Etzinger said: “At the moment, the [Eskom] system is under great pressure. We are unable to do scheduled maintenance because the demand has increased. We are under stress, and we need 
demand-side management (DSM) now more than ever.”


He further explained that DSM consisted of overall management and energy efficiency, as well as growth management, and what was called the ‘virtual power station’, which means that the system operator has the ability to control the load. 
The power conservation programme also fell under DSM, as did initiatives such as the roll-out of one-million solar water heaters, which would displace a large portion of demand from the 
grid.

Peters reminded delegates gathered at the SAAEE convention in Johannesburg that the department had outlined a 12% overall target for energy efficiency in South Africa, and to ensure practical application of the target, sectoral targets had been set.

Peters reiterated that government felt that these energy efficiency targets should be made mandatory, as there was a lot of progress on energy efficiency that could be made through no-cost or low-cost interventions.

She added that the Department of Public Works would also soon release regulations for energy 
efficiency in the building and construction industry, which would assist in changing bylaws to 
accommodate energy efficiency.

Peters stated that energy effi-
ciency should also be imple-
mented in the power sector itself, as a recent audit into power utility Eskom’s operations showed that savings of some 1,8GWh a year could be achieved at each power station site, largely through improved heating ventilation and cooling.
Grobler explained that South Africa used four times as much energy for the same economic 
output as Organisation for Eco-
nomic Cooperation and Devel-opment countries, and with energy constraints and price 
increases, companies and con-
sumers could not continue in the 
same way that they had in the past.

Grobler added that performance visualisation, which would make energy use more accessible and understandable, would assist people in monitoring the overall efficiency of a system and ensure it was operating as intended.

National Energy Efficiency Agency acting operation manager Barry Bredenkamp called for more action in the energy efficiency 
environment, and said that the industry needed proper training and capacity building; coordin-
ated activities; informative 
advocacy activities; standards and minimum energy performance 
solutions; as well as research-based innovative solutions, regu-
lations and international best practice applications.
