Abstract
Energy – its source, price, security, and efficiency- are important issues for the world. Energy
management includes planning and operation of energy production and energy consumption
units as well as energy distribution and storage. Objectives are resource conservation, climate
protection and cost savings, while the users have permanent access to the energy they need.
Resorting to energy management which is the process of tracking and optimizing energy
consumption, is important to conserve energy sources as much as possible.
The rapid growth of industrial, and the huge growth of population have led to tremendous
energy demand in Palestine in recent years, so we have to find ways to reduce the dependence
on others, that's by reducing the load on power plants as fewer kilowatt hours of electricity are
needed, which achieve by energy management. From this background, this research has started.
The idea of this project is to implement an energy management program according to the
UNIDO methods for Al Rajeh factory which located in the city of Nablus. The methodology
consists of four steps, where the first one consists of eight stages, and in this project, the last
four stages were implemented.
A walk through the factory was done, in four departments (plastic, detergents, wipes,
administration). The bills of 2021 were collected, whereas the electricity consumption was
447,858 kWh. In addition, the most consumption was from the cooling system that consider as
the utilities, which are 3 chillers, and 2 cooling towers. Measurements of (currents, voltage,
power) for each equipment was done by using multimeter. These measurements were felt in
mapping tool that helps to understand the factory better. Then a comparison between
measurements and bills was did to check the energy balance.
After that, a saving opportunities cards were did. These cards contain the ways of achieve
saving by improving the energy efficiency. There were 5 cards felt, as follow, ‘Changing diesel
forklift to electrical forklift’, ‘Purchase the plastic bottles from outside instead of producing
them inside’, ‘Changing the cooling system equipment by a central chiller, and installing
inverter (VSD)’, ‘Changing the cooling system equipment by two chillers, and installing
inverter (VSD)’, and ‘Installing inverter (VSD) for each cooling equipment’. The annual of
each card as follow: 12,130.8 ILS/year, 86,202.32 ILS/year, 5,338.63 ILS/year, 4,859.36
ILS/year, and 10,514.82 ILS/year, respectively.
