dc.description.abstract | Investigations into demand side reductions have
been encouraged by the South African electricity
utility, Eskom, in sectors with high electricity consumption,
such as the cement industry. The South
African cement industry is responsible for 5% of the
electrical consumption for the mining and industrial
sector. It has also been estimated that by 2020 this
sector will be ranked fifth for energy savings potential.
This paper investigates the potential of a loadshifting
(altering energy use method) scheme to
reduce evening peak loads and save electrical costs
on a raw mill at a South African cement plant. A
spread sheet-simulation was performed, which
showed that six hours of load-shifting could be
achieved, without adversely affecting production.
This was corroborated by a pilot study where the
load was successfully shifted for six hours over a
week-long period. The specific raw mill would
achieve a reduction in yearly electrical costs of 2%
when employing this load-shifting strategy. The
results, however, showed that cost-saving opportunities
are highly dependent on the reliability of the
mills and on the change in production demand.
Therefore, load-shifting schemes have to be flexible
on a daily basis to shift load whenever possible. | en_US |
