Abstract
Initiatives that are directed towards improving power management by a utility provider have
to consider technical feasibility, socio-economic and the environment. Patterns of power
consumption world over indicate that demand for electricity has over the years been on the
rise due to increase in activities that demand usage of electricity. Such activities include
construction and property development, development of industries and infrastructure. These
activities have strained the power production, whose development does not match the
increase in demand. ESKOM, a government authority mandated to generate, transmit and
distribute power in South Africa has seen demand surpassing its generation capacity, hence
resorting to load shedding actions. Load shedding imposes inconveniences to the consumers
who are completely disconnected from the grid, translating to unpredictable periods of
darkness. Utility providers have an option of constructing new peaker plants which lie idle
most of the day, to take care of high demand during the peak periods, hence, avoid effecting
load shedding actions.
Various ways of managing load have been presented in this research. In particular, the
research investigated possible ways utilities use in managing their capacity with an aim of
developing an alternative method and tool for Demand Side Management applications that
can be used by energy utility to improve reliability, manage and control consumption of
electrical energy through selective shedding of the load connected to the consumer when the
demand surpasses the utility's safe capacity.
