Abstract:
There is increasing interest in the new deregulated electric utility environment
in assessing the consumer costs, associated with failures in electric power
supply and the responsibilities associated with these failures. Continuous
electric supply is a measure of production in industry and profit in the
business. The uninterrupted electric supply is a desire of consumers.
The electric power interruption may create a significant loss to the consumers
of different sectors. In this study, the types of losses in the industrial sector
are identified to evaluate the losses due to power interruption into monetary
terms. The major loss components are: (i) loss due to damage of different raw
materials under process; (ii) loss due to usage of alternative sources; (iii) loss
due to reduced production, loss due to additional wages and (iv) loss due to
equipments' trouble and damage. In order to evaluate the loss due to power
interruption for consumers of industrial sector, an appropriate mathematical
model has been developed. A questionnaire has been developed to collect
information relating to power interruption. The evaluated loss has been
compared with the electricity bills paid by the consumers. The critical price
per unit energy in captive power plant generation on the basis of power
interruption cost of industrial consumer has been determined. Also, the
relative merits and demerits of the proposed model have been compared with
existing power interruption model.
The outcome of this research will be a guideline to the power system planners
to justify the future plan for power generation. The research will also create
awareness among the consumers by observing the losses into monetary terms,
incurred to them due to power interruption.
