Abstract
Energy conservation and efficient usage are vital to the country’s development. Demand for
energy is ever increasing worldwide due to the depletion of fossil fuel sources and other
related issues. Focusing on energy utilization assessment and consumption reduction efforts
through improvement, better production management and also introduction of new
technologies significant results can be achieved; saving money on energy bills, improving
energy efficiency and maintaining sustainable environment.
The cost of energy as part of the total production cost is significant in the mughar cement
industry in Ethiopia. They spend millions of dollars annually on electric power and fuel oil for
their energy requirement. Hence, considerable work of efficiency improvement on energy
utilization efficiency at the selected cement factory is important.
The aim of this thesis is to assess the energy sources and utilization in the selected factory.
And also, it is to study and identify energy utilization efficiencies of the different utilities of
the factory. Finally, to suggest alternatives based on measurements collected data and
benchmarked cement factories experiences.
In this thesis work energy losses at the selected factory have been assessed. Based on the
losses, energy efficiency performance assessments on the major energy intensive equipments
like electric motors and drives, lightings and the kiln have been done. At last energy
efficiency improvement opportunities both for electrical energy as well as fuel energy are
recommended.
Key words: Energy efficiency, energy intensity Mughar cement factory, electric motors,
industrial energy.
